NASA Examines Technology To Fold Aircraft Wings In Flight
Вставка
- Опубліковано 17 січ 2018
- NASA conducts a flight test series to investigate the ability of an innovative technology to fold the outer portions of wings in flight as part of the Spanwise Adaptive Wing project, or SAW. Flight tests took place at NASA Armstrong Flight Research Center in California, using an autonomous subscale UAV called Prototype Technology-Evaluation Research Aircraft, or PTERA, provided by Area-I.
NASA Glenn Research Center in Cleveland developed the alloy material, and worked with Boeing Research & Technology to integrate the material into an actuator. The alloy is triggered by temperature to move the outer portions of wings up or down in flight.
The ability to fold wings to the ideal position of various flight conditions may produce several aerodynamic benefits for both subsonic and supersonic aircraft.

That’s probably the best quality built rc plane lol
Nasa quality
Probably cost half their budget too
Not even. You should see the large scale airliner replicas ppl make. Quick UA-cam search will show some of them. I think someone did an A380.
@@gtdrummerdude Whilst I completely agree with you that there's some of the kits available that are very high quality and some of the scratch built kits have had so much attention to detail that you can take pictures of them and with nothing in the shot to give a sense of scale they could easily be mistaken for the real, full sized version, right down to exhaust smoke stains etc, this does look to be extremely well made. It would likely be a one of a kind model too. They would have gone to a lot of effort making moulds for the fuselage, wings and tail sections, then vacuum formed them to get rid of all unnecessary resin to keep the weight down and strength up, and they've done a beautiful job of that. They may use the moulds for making more, and probably do with the fuselage at least, this may not be an exact replica of anything, but it does appear to be very well made. But yeah, some model makers are pretty incredible at making highly detailed and very realistic looking models.
@@lorditsprobingtime6668 Your answer shows that you have no idea what people make lol. I personally know one guy who spent like $30,000 making an F16 replica. If you look thru my channel you will see a video of it starting up and being flown. It has wheel brakes, hydraulic retracts and everything. He spent 2 years making it.
I'm positively surprised nobody has commented about the shape of the flight path you can see on one of the monitors
It looks like a giant ...
Johnson! What is that over there? It looks like a huge..
Pecker!... Wait that's not a woodpecker - it looks like someone's...

Hahahahahahah drawing dik
Haha I saw that and thought they were in the penis pattern

That's only a normal and simplest fight path to test the model planes but dirty minded people can only think of dirt outta any damn thing.
Damn that's cool, NASA really knows how to build one heck of an RC airplane lol.
Krazy Kids ho yeah
warzoneearth R&D isn't a waste of money. Your education apparently was, though.
warzoneearth, but if it means cheap flights?!…
I have to agree with Pete Smith & Calvin Hodgson. A lot can be gained with this R&D both in the military and civilian sectors and not every thing is a waste of tax dollars and there would be no way to tell unless you have access to every thing they do so anything you say with out facts is just baseless.
Wasting tax dollars would be not building a small-scale prototype of new technology.
What is this?, a commercial airliner for ants!

Its for testing purpose for further studies

More than 50...
That was the best RC airplane landing I've ever seen.
so smooth
pretty rough landing actually I wonder if it was LOS or strictly remote instrument. the EXCELLENT suspension system they use (which I really want to duplicate looks sick!) is what made it appear smooth.
I wish the video explained the purpose of researching folding wings. I was expecting the wing to fold inwards to maybe reduce drag for efficiency. but from the video it seems they only fold the outer tip. Now I'm left wondering what is the benefit from that. Doesn't seem like it reduces drag, does look like an oversized winglet, maybe it could increase stability in a current?
Stability increase at high speed, lift increase at low speed
It’s so they can have a job and something to do. Back in the day Nasa was flying space shuttles but now? I don’t know what they are doing.
@@thedubstepaddict3675 - Flaps do that.. but based on the 777X, it'll help with efficiency.
Folding the wing reduces the induced drag. Since Induced drag is proportional to the square of Cl (Co-efficient of lift), as the wing folds Cl goes to zero for that particular bit as it's no longer producing lift and hence induced drag reduces. It also acts as a partial winglet which further reduces vortex causing less decrease in local lift and induced drag. The system is basically designed to give more lift when taking off and landing while reducing the drag when in cruise flight. It also reduces complexity and structural weight. At high altitude as the density decreases the lift also decreases. To generate more lift the aircraft could then use its tips. The video should have explained these points.
Wing folds -> Smaller Wing Area -> Cl goes to Zero?
Complexity going down compared to a Winglet?
Biggest contribution to drag in cruise of an civil aircraft with about 2/3 is still the friction drag. So having the tips is normally an disadvantage at cruise. As far as i know there is always a trade off between lower induced drag at take off and friction drag and cruise. So the best thing would be using the Winglets at take off and then folding them inside the wing, so their surface doesnt increase the friction drag at cruise.
So, i am still not sure what they are researching/ testing in this video
Albeit for research, as a serious fan of R/C commercial airline videos and the hobby itself, this was the ultimate R/C airplane video!
From the thumbnail I thought the plane was enormous lol
Am I missing something? I thought the wings were going to fold in?
J Jill yes you missed it
They already have wings that fold in. They're call variable geometry wings. Look up the F-14 Tomcat.
@Panther 74 Escaping what benefit does it have?
The wings were also folded up right before landing, and were shown extending.
@@DocxHammer no that's swing-wing, they don't fold
NASA, thanks for sharing this. It might be helpful to have someone do a brief introduction explaining what research is being performed during the test. Thanks!
Poor NASA they are way too underfunded. They put a man on the moon and now they’re playing with model airplanes.
All they need is a small model for data analysis.
They're not in the space race anymore... so the government is indifferent towards the matter...
for safety purposes, real flight might cause casualties. so yeah.
Thats what ya get when you loose the blueprints for the machine that got us there in the first place! Like its 2020 and nobody has an answer to why American people lost the only achievement we have as a civilization? The 1 thing that nobody else has ever been seen to do in our galaxy and we lost the blueprints and over 50 years later we got talking cellphones bit still no engine to propel us to the moon...that is eerily weird....
Paul Short You’re not one of those “THE MOON LANDING WAS FAKE!!!” people are you?
I would love to see them test variable profile wing shape. Have a thicker profile top to bottom at take off then slimming down for high speed.
@2:10 I've never seen a guy spin a pen so quick across his fingers since Top Gun lol
First thing I thought of was a new way to load passengers with that flip top lid.....that or a barbeque when the landings not so good!
What benefit does this feature add to the plane? Apart from looking like the wings broke and giving passengers a very long stressful flight.
Read up on f14 tomcat and why the wings moved.
Reducing drag because of vortices
Derrick Moses a swing wing like the f14 moves in a different direction and is nothing like this
Boeing 777 has folding wingtips
@@nczioox1116 777 max has folding winglets but doesn't really fold in flight only folds when landed
"On subsonic aircraft, such as commercial airliners, the potential aerodynamic benefit of folding the wings includes increased controllability, which may result in a reduced dependency on heavier parts of the aircraft, including the tail rudder. This may result in a more fuel-efficient aircraft, as well as the ability for future long-winged aircraft to taxi in airports. Additionally, pilots may take advantage of a number of different flight conditions, such as wind gusts, by folding their wings to adapt to any particular condition experienced in flight.
One of the most significant potential benefits of folding wings in flight, however, is with supersonic flight, or flying faster than the speed of sound." (source: www.nasa.gov/centers/armstrong/feature/nasa-tests-new-alloy-to-fold-wings-in-flight.html )
"The Spanwise Adaptive Wing (SAW) is a way to articulate the outboard portion of the wing in flight to effect a variety of multi-disciplinary, multiplatform benefits. SAW incorporates advanced actuation technology which allows the outboard portion of the wing to articulate in flight. This allows the outboard portion of wing (hinge span) and its corresponding control surface to be folded to the optimal setting for the flight condition. In doing so the aircraft sees significant increases in lateral-directional stability and control augmentation. The increase in lateral control enables increasing aircraft efficiency by reducing the rudder through the incorporation of SAW. Supersonic benefits include increased compression lift and reduced wave drag, and is an enabler for supersonic flying wing design." - NASA website
Phil Pan You also forgot to mention (SAW) Is also being developed for the worlds Airlines an airports in general . Primarily so airports can fit more larger air craft in densely pack aprons without violations to regulated space allotments at the gates, airlines in general will also see enhanced takeoff / Climb / Cruise & Descent profile efficiencies with there aircraft that are fitted with a (SAW) Ability to the wings as standard from there respective aircraft manufacturers. Maybe saw is a long ways off for the aviation industry as a howl, but I do know that AIRBUS & BOING are actively investigating adaptive & Folding wing profiles for there future product line of aircraft..
The only main line passenger airline Manufacturers in the industry to be doing so as far as I'm aware..
Not directed at you Phil, but this concept is lame! this is an old solution created for WW2 carrier decks (F6F Hellcats). if you up-scaled this idea to commercial/revenue airframes, you would gain ramp space but lose overall fuel capacity/range.
hellcats didn't fold their wings in flight, however, 1960s xb-70 valkyrie did
OfF, I think you miss the point, it is not about space on an aircraft carrier, it is to do with an alternate way of changing the wing dimensions/shape inflight for the best efficiency for lift/drag at different ends of the speed envelope. A wing shape for cruising is not a good wing for supersonic flight.
I respect (almost) everyone's opinion, but I find it a bit much for armchair trainspotters criticising NASA on this page, to comment on the work of highly-skilled aeronautics engineers, especially by saying things like "lame" (not specifically directed at you, Omlette). This is pure research and it is what NASA has been doing since its inception. It conducts research in aviation envelope paramaters in order to further the understanding of the realm. Many things we take for granted today in aviation has come from NASA's research. Engineers and scientists who conduct this type of research should be applauded for their efforts and the progress they help usher. Don't you think that they know a thing or two about airfoils and aerodynamics ? Don't you think that they could wipe the floor with your Wikipedia or UA-cam-acquired knowledge if you debated with them ? They know what they're dong and why they're doing it - they're studying specific parameters of aerodynamics that you've probably never heard of. So tone down the rhetoric and act in a more constructive way: Share knowledge and ask questions instead of taking cheap shots that only manage to make you sound like neurotic fools. Those of you who helped raise the shared knowledge by mentioning technologies that are associated with this kind of research, are doing the right thing.
Now they need to speed that up and they have a bird
The North American Aviation XB-70 Valkyrie had wingtips that could fold down in flight when it was designed in 1958. North American improved on the basic concept of compression lift by adding a set of drooping wing-tip panels that were lowered at high speed. This helped trap the shock wave under the wing between the downturned wing tips. I don't know if the wingtips could be turned up to become winglets though.
NASA should invest in a huge RC Plane dogfight😂 just for fun
That's what we called R&D
That's basically called a drone
@@videogamechannels360 We spent a lot on you, that was a waste also.
Huh, first surprise is that it's a model! From the thumbnail pic I easily believed it was a full sized aircraft. Attention to detail was excellent by the builders, it looks beautifully made. Still trying to understand where any benefit from them folding down 90 degrees might be, still the same area of wing creating drag, just less lift. Folding up of course can be handy on the ground.
IT'S PROBING TIME ! 666 Bruh it has shopping cart wheels
@@jackkollhoff9519: " Bruh it has shopping cart wheels."
Are you really that dumb, or are you just joking? No, they are not shopping cart wheels, unless you're using a shopping cart with suspension and brakes and is that is. And what the hell is a "Bruh"? I've never known one of them. Oh, and that's ok, I edited your quote to add the missing punctuation for you since that's clearly too hard for you. I didn't want everything you said to look completely stupid.
IT'S PROBING TIME ! 666 Holy shit someone has a dick up their ass, first of all kid they are shopping cart wheels, just because someone adds breaks and suspension to wheels doesn’t change the wheel. Sit down.
That's cool and all
But besides a starwars lambda class shuttle, what would you use it for
Uh, clearly to improve upon the T-4a
To increase the efficiency of aircraft in flight and take up less storage space
Decreased lift/drag = faster cruising speeds.
Wide wing= mire lift at slow speed.
However, this makes it difficult to move quickly due to leverage on the structure and drag.
So taking off with a long wing, then transitioning to a shorter wing is a good idea
@@joesmith389 Or same speeds less fuel consumption.
Can it land in various stages of fold failure? Interesting approach and a hat tip for applying modern materials and technology to an old concept that was hamstrung by cost, scarcity of materials, and complexity.
You'd be really surprised at how complex that thing is.
@NASA Armstrong Flight Research Center >>> Does this partially create _compression lift_ when the outer wings are in the down position?
Luckiest bunch of guys with best job.
Isnt that just personal preference kind of thing really? If you are super enthusiastic about trains wouldnt you seek a job at the railroads/trains, like train operator/driver.
To me their job looks boring af, stare at instruments on a screen while you sit in a booth on the ground.
SCREW THE FRUTS ON THE COMMENTS!! IF YOU LIKE RC PLANES AND YOU NEED 1MIL. TO FUCK AROUND TOTALY AGREE WITH YOU! BEST JOB
@J Michael not everyone has the gift of, say, having a mind for mathematics. Some of us LOVE these sorts of things without truly loving the technicalities behind them. Some people love both though!
Funny!
Making millions of dollars doing it, too.
What are the advantages of being able to do that can someone explain?
Reduced drag and aerodynamic performance. Also, think about planes on an aircraft carrier that fold wings so more planes can be accommodated. Apply that to an airport and they would be able to build planes with longer wings that create more lift, and then fold up while taxiing around an airport and parking. Apparently this new alloy can also change shape based on temperature. If you have ever been on a plane in very cold weather, the air is more dense and the plane performs better. They would be able to build a wing that automatically takes on the most efficient shape possible based on the temperature, and therefore get more lift and less drag. Apparently it also helps in the transition between subsonic and supersonic flight.
@@JeepersCreepers2013 to bad they don't try it F14 style, look much sexier.. but i get it the wings heavy as fuck and to sweep them back.
I'm not an expert but the extra width help plane takes off at lower speed, but not needed at cruising speed as they add drag. So it fold them up and work as a stabilizer. Is that it?
damn landing is so smooth 🤯
Wait, the XB-70 was capable of this in the back half of the 60's and at Mach 3. (If only once. Plenty of flights an Mach 2+.)
America, reinventing the wheel. They could have asked any model builder if it works manybhave done this already on small scale.
2 things, acutally 3,
1. XB 70 was a experimental bomber(later reconnaissance) but xperimental Bomber as the first part stands for
2. It couldn't it could bend the tips of its wings 15 degrees
3. Even if this was true nasa Is Severely underfunded they get a few billion a year I believe while army gets 600 billion so yeah.
1:56 actually thought for a second I was on a real airliner cruising!
What for? Will this get us there faster? Will it allow us to go outer space?
That will save a lot of drag..Awesome work guys
The aeronautics space race is extremely important for space travel .I love seeing the new projects that America is working on
Mate NASA ain't gonna get u into space, private companies are gonna get you to Mars and mining asteroids not NASA
What's the point?? Is there a benefit? If so, I wish it was explained.
Craig Dillon I imagine the extra wing length allows the plane to use less runway because of the extra lift and it's easier to store

But those people are going to be replaced by machine learning AI robots soon.
true, the entire industry is going to disappear soon, yes. but those people still have cooler jobs than this, which was what I was saying
Everything will be replaced by AI eventually. Probably.
Indeed, coolest job ever. Those guys get to test cool ideas, get to build & play with extremely cool RC/autonomous/FPV airplanes and even get payed to do it. As for not really being up there, etc, I'm betting that many of them are also pilots and have their share of real flying as well, so that's also covered.
If they wanted to test the aerodynamic characteristics of folded vs extended wing configurations, would it not be cheaper and easier to fabricate both types of wings, and test fly each? What does having the wing tips extend, fold, or whatever in flight tell you that different static wing configurations won’t, unless, of course, the tips of a lowered tip version would scrape the ground. That could be addressed y using longer landing gear struts.
Nice video liked it. Don't know why this was on the mind after watching a USA air force planes landing on highways closed off. It was on my mind on why airplanes are not open and close wings well in or on the fly. The video is about changing the short part of the wing as in up and down. Is there a video on the wing level with itself? Be it under or over the solid part of the wing. If the tips fold over the wing will there be flaps with it? That could work like the many planes that have two flaps to stop. Like on one wing air force planes? Last question What change makes the tips when one up and one down? As in airflow. Too many questions .. sorry.
Probably the goal was to make use of the large wing span at takeoff and landings and during cruise to stop the span wise flow?
fadoobaba seems like you want span for cruise. Better L/D which would improve efficiency. I'm guessing shorter span is better for supersonic
Actually, not only is it better for transsonic speeds, but it also fights the vortices formed at the wingtips.. Those create a lot of induced drag, so for cruise you migth want to fold them upwards/downwards. this is not changing span only, but the surface area, so it might decrease the stall speed for landings..
yes, this is what I meant, fold them for cruise.
Václav Marek L/D would decrease with folded wings at subsonic. Bad for cruise
Shadowboost not so sure, the drag equation dictates that the induced drag is proportional to the lift coefficient, aspect ratio, oswald efficiency number, and cd0 will probably stay similar. I would have to see the data to do the calculations, but the change in lift/drag might not be negative. Actually, decreasing lift is desirable at high speeds.. too much moment at AC to trim for.
When plane was running on ground than it was even smoother then my car. Either the ground was very soft and levelled or the plane's landing gear was fitted with extra soft suspension. Amazed by NASA's RC plane 😂
I'm wondering if the old F-111 wing concept would be a better or more effective way to accomplish the hopeful end results?
Okay. So if they said that temperature triggers whether the wings fold up or down, does that mean they have sensors in the wings that detect temperature and then use motors to fold up the wing or is the alloy moving without any assistance?
Piccolo Autopilot and PCC FTW!
@yellowbikemike keen eye! If you look closely, however, Piccolo autopilot isn't engaged. Pic serves as a backup to Area-I's autopilot (middle, top, and left monitors) which flew the mission, performed SYSID maneuvers, and controlled the SAW actuation.
Just look back at the fastest Bomber ever built the XB-70 it drooped it's wingtips in flight to capture a shock wave to ride like a surfer does a wave
Instead of folding why not hydraulic extension, just like a radio antenna length can be changed?
It's nice to see the older technology still is being used.
Well, the image stabilization was awesome!
So many idiots in the comments. The scale model lab at NASA has been around since the 50s its an inexpensive way to test new concepts. Also why are people comparing this to the F14? totally different things F14 had variable sweeping wings while this folds a section of the wing to create a large winglet like surface. For those asking what are the benefits.. well thats what they are trying to see maybe it's better at controlling vortices then traditional winglets, it may also reduce drag and improve fuel efficiencies maybe improve flight dynamics as well. All we can do is experiment and learn. People need to start thinking outside the box for once. A lot of great things come out from NASA research like this
Reminds me of the B70 Valkyrie folding winglets. They fold them downwards for "compression lift" it gave the Valkyrie added lift while also reducing drag at supersonic speeds.
One thing is that the flight plan for the test plane was shaped like a d*ck.
newatlas.com/nasa-wings-memory-alloy/53053/
Ruben The new Boeing commercial jet incorporates similar technology (outer portion of wing swept back more than inner 2/3 of wing in place of winglets).
Do you know where we can find results of this experiment?
What is the need for the wings to fold what does it do for flight
How many time that these wing can handle of folding every flight?
is this whole plane out of carbon fiber?
Yes, this whole 'merely the size of a car' plane is completely made out of carbon fiber. If that is surprising to you then realize that the Boeing 787 Dreamliner's air frame is entirely made up of composite materials.
Darius Duesentrieb yes, to make it more light weight, some commercial subsonic jets are made of this partly.
black doesn't mean carbon fibre....it may just be paint
Abhîshek Kumar But you can see the carbon fiber mesh at some points of the video
Abhîshek Kumar Look Closer. It’s carbon fiber
What a coincidence! lSlS is examining technology to fold aircraft in flight.
veriable wing geometry in flight next step to atmosphere to near space flight and beyond
What's the benefit of the wing tips folding up or down? Whatever it is, is it really worth another moving part that could malfunction, short out and catch fire etcetera? This is one of those "if it ain't broke dont fix it" situations.

Jeremy kyle
lol too late I did this a while ago
NASA should totally package this plane as a kit and sell it on Amazon. Plane, control trailer, radio links, ground support services, haul trailer and all.
Are the airspeeds they are calling out in Knots or Kilometers per hour? If in knots why do they rotate and take off at such a fast speed for such a small aircraft? Cessna 172’s rotate at around 45 knots and climb out at around 70 knots. That plane in the video didn’t rotate until around 70. Is it that heavy?
@NASA Why do you want to fold the wings in flight..? What's the purpose..?
Vishal Ignatious It significantly reduces drag on the aircraft yielding better fuel efficiency in the long run
Who remembers the XB 70 Valkyrie ? Make a new one NASA !!!
What purpose does folding the wing-tips serve? Would someone mind putting this little clip into context (i see no aero benefit, and so little of the wings surface actually "folds" that this surely hasn't been developed as a space-saver)... anyone?
Good . I am love with those guys who are involved in innovation!👍
Looks like the dry lakebed at Edward's. NASA, don't you have all the data from the XB 70 and its wing folding? Think it was termed as "compression lift".
What's the use of foldable wings...??
Anyone can explain this to me??
Foldable wings make the aircraft take less room at the airport. When you are in an airport walking half a mile to get to a gate it's because the gates have to allow room for the huge wings.
Turned up or down wingtips improve efficiency. This test aircraft allows them to test many different configurations are best, and see if a variable configuration might be worth the extra cost/weight.
TexMex they are actually to test for aerodynamic benefits to moveable wing tips, but st this stage Boeing has it already figured out and implemented o their new 737s, so really NASA is just wasting money instead actually doing work in space.

@@anshulsingh8326 Uhm, uhhh ur welcome?...
this is to cause the noise, or what I call sound being directed vertically rather than horizontally?
So which is better aerodynamically, folded up or down?
But after what's the advantages if plane wings r folds
Not mentioned
im looking the comments to find it lol
Just as a guess, I would imagine they have a drastic effect on stability/maneuverability.
I'm basing that on the current "anhedral" (downwards angled) wing design you see on large transport category aircraft. These large aircraft use an anhedral wing shape for better maneuvering characteristics in turns/rolls.
That's just my guess.
@@aviciouswalrus1303 could be, but i don't think NASA would do such simple shit. They like to do more scientific shit. I feel like that isn't their thing, it's way under them, don't u agree?
@@ahmedtofigh2951 well changing the aerodynamic characteristics of a wing profile in flight without any loss in altitude or speed is hardly simple. This could improve handling characteristics of high altitude flight such as strato/meso/thermospheric flight where the air resistance is much lower.
Again, this is all speculation because I dont work at nasa. But I see very few other possibilities or reasons for a wing profile change in-flight.
@@aviciouswalrus1303 so basically what ur saying is that it can help with maneuverability at cruising speed where the altitude is high. we have the auto pilot that keeps controll over all this, it's not like you would manually controll the airplane at crusing speed, this wouldn't happen. The autopilot does it all.
That is very cool! I cant wait to see what wonderful things result from this.

what good will folding wings in flight do ?
That's a heck of an RC airplane club!👍👍👍
What benefits will this design feat have ?
In theory improved control and reduced stress on some sections of the aircraft frame, you should be able to find the article by NASA fairly easily through Google if you'd like to know more!
I believe I read Supersonic flight capability somewhere in the video description.
The supersonic lift benefit will come from a phenomenon called compression lift and has only ever been used in the XB-70 prototype.
Bharath Sampath Kumar supersonic flight can be reached by many fighter jets
"The wings were folded during the flight using a thermally-triggered shape memory alloy, developed at Glenn Research Center and integrated into an actuator at Boeing Research & Technology." - www.nasa.gov/centers/armstrong/feature/nasa-tests-new-alloy-to-fold-wings-in-flight.html
That is so dang interesting! Watching again after learning this made the video even cooler, and it was already pretty neat.
Thanks for the link!
i have a question what will the flippled wing will do?
What for we need to have folded wings ? I means what's the purpose ? Please educate me
Didn't the XB-70 Valkyrie have a folding wing like this some 50 years ago?
But that was built for a different purpose, keeping the shock wave attached to the wing leading edge, to the wave rider effect, this is a subsonic aircraft, probably drag reduction and so lateral stability improvements?
While you're at it see if an aluminum airplane wing can slice through a 2" steel I-beam.
Doesn't need to it can break and slide in between the beams then ignite and soften all the steel beams.
@@humansrants1694 So why wasn't any of the 'broken airplane' found on the street, below where the airplanes struck?
All I'm thinking about is the maintenance us A&Ps will have to do.
What second did they fold it? I cant find it?
For a second I thought this was made by The Onion
Why not just redesign the fuselage into a lift body design? Has worked for decades in some fighter jets.
NASA is looking into that all the time and has had a big hand in doing research for those fighter jets. On top of that a comment higher up mentions how this technology is "an enabler for supersonic flying wing design", a lifting body plane.
From what I understand haveing wing tips that fold would actually increase the traveling distance ( kind of like the aircrafts that are commonly used 737,748,777 etc) of the craft because of the wind flow over the wings allows for a smoother flow
But then allowing it to extend upon landing aids it in landing🤷♂️
Just a thought 💭
Great video especially from inside.
This tech had been around since the Xb-70
Not really...
The XB-70 drops a third of its wing at sub to supersonic speed to; better take advantage of the compression lift, generated by the fuselage and intakes of the plane; increase the vertical surface area allowing shorter vertical stabilizers; reduce the rearward wing area, countering the delta wing's inherent rearward shift of the center of lift as speed increased. Valkyrie used motors and hydraulic systems to fold the wing.
This NASA project it's totally different, and if you had read the published article on their site, you would see they actually mention the XB-70, and explain the basic difference between both wing folding systems:
''Folding wings in flight is an innovation that had been studied using aircraft in the past, including the North American XB-70 Valkyrie in the 1960s. However, the ability to fold wings in flight has always been dependent on heavy and bulky conventional motors and hydraulic systems, which can be cumbersome to the aircraft.''
''The SAW project intends to obtain a wide spectrum of aerodynamic benefits in flight by folding wings through the use of an innovative, lightweight material called shape memory alloy. This material is built into to an actuator on the aircraft, which plays a vital role for moving parts on the airplane, where it has the ability to fold the outer portion of an aircraft’s wings in flight without the strain of a heavy hydraulic system. Systems with this new technology may weigh up to 80 percent less than traditional systems''

Edit: English is my second language, apologies for any mistakes, I hope I was clear enough tough.
So they build and pilot RC airplanes for NASA and get paid for that. Lucky bastards
What is the necessary of folding wing
What would be the need to fold the wings in flight??
and...?
They extended the actual size of wings just to fold wings midflight...🤔
"Extended" as opposed to what? They designed this thing, the wings are exactly the size they were calculated to need. And yes, they folded them mid flight, that was the whole purpose of the test. Once speed increases you need less surface area so they 'can' safely fold a section up or down. So what's the point of your comment, because I can't see any. If they'd tried taking off without those ends out, or even removed, takeoff speed would have to be ridiculously and dangerously high. So if you've actually got a point you'd better try explaining it better than that.
@@lorditsprobingtime6668 He was joking though. Like it was a joke. The whole premise is rather ironic if you don't understand the physics behind it. Sit.
@@gabbytea2253 Maybe you've got some sort of ESP powers. It didn't sound at all like a joke to me. Add the confused emoticon and it seems fairly clear to me he hasn't got a clue. He's had plenty of time to explain himself so I'll stick to my original opinion opinion that he doesn't have a clue but felt the need to say something stupid instead of asking a direct question. A lot of idiots in YT discussion sections seem to do a lot of that. Don't understand so try and make it sound like the people involved must be the dumb ones, it seems to be standard practice for a lot of the idiots who post in these comments sections.
@@michaels882 That's, um, well, just plain wrong. It's to signify confusion, lack of understanding etc.
@@lorditsprobingtime6668 Its time to go watch other vids now. Your comment was appreciated, but unnecessary
This was so cool to watch. Thank you.
Nasa: fold wings in flight
Xb70: hold my machometer
XB-70 Valkyrie : Am I a joke to you ?
2:10 look on his screen
lol
single balled pp
A pp lmfao
Taejun Chang there’s two balls if you look closely you can see it
Hmm, it's nice to see research continued on this.
However, I don't know why some people would think that this is radical or new considering that inflight folding in the vertical direction was already very successful with the XB-70 Valkyrie decades ago.
At the airport: don't get too close to turbines
NASA: your leg can get close enough
