This video only explains the manufacturing process and the plane and does not explain at all how it works or how the wheels can actually support the weight of the plane.
The video shows the manufacturing process, the tools, the finished parts, the size of the finished parts, the assembly process, the size and types of aircraft, the different sizes relative to the aircraft and their real world testing methods. In other words, how it all works to support the weight of the plane. How did you miss all of that?
Yeah. What A WASTE.
@@BillStemil 🤣 You clicked on a 14 minute video expecting to see the maintenance manual of a 747 landing gear? Hell, I’ll sell you one and watch you complain it’s too long.
@@BillStemil So, you said ‘yes’ you wanted more engineering info in the video, then said ‘no’ you’re not complaining about the video. Then I suggest where you can get that info and you trigger. Hmmm, I’m glad you don’t fly real aircraft, you don’t have the temperament for it.

Good Stuff,😄👍🏿 Proud Dad of an Air Force Airman
OK, so I’m just wondering, after watching the entire video: how does a landing gear support 400 tons of aircraft?
Me too!
There was a hurricane that did some damage to Kuai, Iniki(?) 1992(?). A FEMA team was sent immediately. They brought a communication rig, generator and two fuel trucks...in a C5. Kauai has a short runway. No C5 had ever landed there(?). So, while the FEMA team was on the way, the Airforce flew a C5 from the Philippines...to try it out... That C5 landed alright.....but it was empty. My friend was on the C5 with the FEMA team....and all of their gear...really heavy! He said that he never heard the landing gear, tires and brakes roar so loudly.
I remember when I was a kid long time ago at my grandfather's farm one day we heard a story one guy from our village bought an old landing gear at junk yard and he mounted the tyres on his tractor trailer , it took five men to set one tire for a whole day. He said this will last forever and he took a hammer and a knail try to puncture the tyre and nothing happens ......
IN BALDWIN KANSAS DURING WW2 THERE WAS AN SMALL TRUCKING COMPANY THAT HAD DIFFICULTY GETTING TIRES FOR THEIR TRUCKS!
ON ONE OF THEIR DELIVERY ROUTES WAS AN MILITARY AIR BASE, AND THEY HAD A BIG PILE OF AIRPLANE TIRES THAT WERE REMOVED FOR SMALL DEFECTS,AND WERE CONSIDERED UNSAFE FOR AIRPLANE USE!
THEY WERE GIVEN SOME AND THEY TOOK THEM HOME.
THEY WERE ALSO BLACK SMITH AND METAL WORKERS AND MADE TRUCK WHEELS TO USE AIRCRAFT TIRES! THEY THEN HAD GOOD TIRES WITHOUT RATIONING!
AFTER WW2 THEY STARTED ADAPTING AIRPLANE TIRES FOR FARM MACHINES TO WORK IN MUDDY FIELDS, AND THIS THEN BECAME A BIG BUSINESS, SELLING WHEELS AND AIRPLANE TIRES ALL OVER THE USA !
OMG é Power-Phull Orrrsé-Strâylêans
Can anyone could tell me ? this landing gear this strong carries all that weight, and the pressure of plane hitting the runway could evaporate after the crash ? like they told us the plane that hit the Pentagon just evaporated went up in smoke like the entire rest of the plane, boy that must be some special fuel LOL did anyone bought that BS explanation from the Government?
You mean he put aviation tires on his road transport prime mover or his attachment for his off highway farm tractor?... Cause I could see how the latter could probably work, but there's no way anyone is using them for a highway truck. Even if you used small ones, they're completely the wrong type of tire for the application and they wouldn't last long at all.
@@C.Fecteau-AU-MJ13
YES HE USED THEM ON A ROAD TRUCK AND AGRICULTURAL USE ALSO!
DURING WW2 TIRES WERE SEVERELY RATIONED IN USA !
HOWEVER AT THE AIRFORCE BASE THEY WERE THROWING THEM AWAY IF HAD DEFECTS.
THE BUSINESS OF TIRE AND WHEEL CONVERSION BECAME THE HEY MACHINERY CO AT BALDWIN KANSAS!
THEY ARE STILL IN BUSINESS TODAY !
Very nice video ! After the engines, the landing gear is the second most expensive unit in any jet aircraft.
I would think avionics.
@@davidrico52 I would actually say the Airframe was.
@@Smakheed I think its the airframe too, particularly a heavy 12Y check
Yeh the C130s my fav transport. if we're lookin at amphibs, the Catalina, and fighter/bomber, the Mossie. Not overly fond of the ones, who only go as fast as they do if the arse or their wings are on fire. Glad you mentioned these blokes in the metal shop, they deserve more credit than they get!
"...painting with laser-like precision..." LOL!
The painting is the most important part if that’s not right than they have to redo everything
@@chadbroski342 say what?
"This 747-8 is practing what's known as a rejected take off" Shows the plane taking off
True... 🤣
Saw that and was like...... Damn, guess he failed the test???
Superb engineering!!! What goes up must come down..... safely!!!
Agree...
It would be nice if we put as much care into our roads as they do with the landing gears.
@@nyccollin That’s not a question, it’s an admission of mental defects and a cry for help. Please seek professional help.
As mentioned earlier by Bill Luce, your facts need to be revised. The landing gears on the A380 were in fact design by two different companies. Safran designed the Nose Landing Gear and it's components, nothing else. United Technologies Aerospace Systems (formerly Goodrich Aerospace), turned Collins, now Raytheon Technologies designed and manufactured the mains; the body gears and wing gears.
What are body gears and wing gears???
The landing gear under the body and wing of the aircraft
Incredible human state of the art design,great achievements
How I wish people can also love one another in the same commitment!
I think these industrial workers also should be getting awards same as those who are in the battle field...
Best beautiful sharing ❤️❤️🧡👍
Very interesting, thanks for the technology of the landing gear, had no idea
Totally agree!
The most dangerous part of flying are the takeoffs. The fuel tanks are full, so that plane never weighs more, and it's rippin' down that runway with all that weight pressing down on those tires. A simple tire blowout would be cataclysmic. Once the plane arrives at its destination and it's ready to land, the fuel tanks, and therefore the plane itself weighs far less, so the tires aren't as stressed. A fellow passenger I had just met was nice enough to share this info JUST before taking off. I'll never forget it.
That just isn't true though, a blown tire isn't a catastrophic failure, and yes there is a lot of jet fuel, but you also have less momentum. It's also worth noting that taxi is the same as the runway in your example if not "more dangerous"" since you don't have enough speed to generate lift, which means all the weight is on the aircraft's wheels. As the aircraft is accelerating down the runway it builds up speed and therefore lift, as lift increases the weight on the wheels decreases which in turn makes it safer (in your flawed example). So, I wouldn't let that random guy scare you. Even assuming there was a blow out of the tires there is 2 on each wheel, which means you would have a backup and just abort the takeoff. (Which mind you is extremely rare.) Even assuming you had both tires blow out which has happened before look into the February 22nd, 2022, A plane headed to Phoenix with 142 passengers blew two tires during takeoff, but the jet stopped safely on the runway. Passengers were transferred to another plane, and no one was hurt.
So, to summarize, this is just not true in any regard, so don't worry about anything in future flights. And if you really want to know the most "dangerous part" it is universally considered to be the landings. Since you are at the extremes of the flight envelope among other factors, and since statistically, nearly half of all fatal accidents have happened during the approach / landing phases of flight are the most dangerous.
Tire explodes, full reverse if speed below V1.
I worked just north of a c5 base for years. It always amazed me how quiet these behemoths were. They would fly over at just a couple hundred feet. Never heard them till after they flew over.
Should have worn those ear defenders early on before you lost your hearing. 😂
They make a very distinct whining sound. It's not a straight jet engine like on older b52s but I would never have said I never heard them until overhead
@@scottallberry6713 So do most Americans although you hear them half a mile away.
M
Real question is why are 95% of the engines in front of the wing and always have been? Mandela Effect
Very good job, 🎉👏 congratulations
Did anyone else realize that 28 tires on the C-5 divided by 4 engines works out to 7 tires per engine?
28 divided by 4 equals 7? You don't say!
@@tettazwo9865 I know, it truly is astonishing, but I've run the numbers several times. Checked, double checked, cross checked and I keep getting the same result. Incredible!
Tbh that is kinda impressive. Those engines put out so much power you need 7 tires just to stop it
Fortunately they were very strong and well built. considering the weight of the plane and its passengers. Also having the means to withstand the force it takes to land. Also credit must be given to the pilot / copilot to land safely so that the front wheels don't bounce. I flew, ( for the first time last year to New Orleans ), and a friend told me to just relax, it'll be like going uphill in a car.
The landing gear on all aircraft get more stress than any other part on the plane. The landing gear must do this for many years. They still must be as light as possible.
I wonder why aviation engineers do not make large parachutes that help stop large aircraft. This is a simple process and preserves the life of aircraft tires.
Marvel of Engineering 👌🔥🔥👌
An Engineering Marvel Reflecting Superhuman Effort . Just Amazing every bit of it .
The A380 is a BEAST and a dinosaur that will be phased out of existence
That could be said for the B747, as it's a 4 engine jet, as well.
But, the B747F could be around longer, maybe.
@@walterfink9782 not for freighter the 747 is the best aircraft for moving large amounts of cargo
Great recognition of the part Engineers play.
Pretty much everything on commercial airliner is just insane levels of engineering an manufacturing that is so easy to overlook. Not only do you have the challenges of extreme environmental fluctuations and forces at play but the stakes of failure are catastrophic and on top of this these aircraft are used nearly constantly for decades. Pretty nuts.
super trabajo muy bien!!!
Very interesting technology subject
well done!
very intersting video; but that was not a tank that was loaded on the Galaxy, it is a self propelled artillery piece.
And what is a tank? 🤨😂
@@jordenbronson8122 Not a self-propelled artillery piece that's for sure!
What's shown in the video is a Paladin M109a7 155mm Artillery System.
In other words, not a tank. Cant be bothered to explain the difference, you can look it up yourself if you want to. But a tank... that ain't!
@@jordenbronson8122 a tank is an armored vehicle designed to support infantry assaults as well as the tip of the sword to punch a hole through an enemy's defensive line, and then attack and destroy the enemy's rear echelon. a self propelled artillery is not designed to punch holes through an enemy's defensive line and continue the attack. though it is used to support infantry assaults., mainly to "soften an enemy's defensive position from miles away. self propelled artillery is also used to fire from positions that towed artillery can not get access to.
so the 'how these bogeys can support an aircraft' question is answered 'somehow'. The Antonov 225 nose gear can 'crouch' to assist loading and the thing has 32 wheels holding up 640 tons (or 1433600 pounds in USA speak) so it might be worth a mention. Also worth a mention are the cases where the landing gear failed and how the design evolved.
I don’t think they’ll bring up that plane because of the animosity involved. Ukrainians don’t want to admit that the plane was actually built by the Russians. It becomes a finger pointing game. Too much conflict between the countries regarding the plane and what happened. Russia will take the plane and rebuild it. It is a historical plane and it’s not entirely destroyed. Just was damaged to where it’ll take some time to repair it. But it was a dated plane that needed to be updated and rehauled with newer and stronger components.
Phoenix sky harbor is about to undergo a project to enlarge one of their jetway overpasses to handle these planes
talking about the landing gear, i'm always amazed the tyres withstand such pressure!
And they actually don't burst until twice the rated (maximum sin-service) pressure. They use a lot more rubber thickness and cord layers than car tires do.
26 ply (layers)tires and 200-250 psi. Car and truck tires are 4-6 ply and 30 psi
"(maximum sin-service) pressure"
The Antonov An-225 Mriya was a strategic airlift cargo aircraft designed in the 1980s by the Antonov Design Bureau in the Soviet Union. It was originally developed as an enlargement of the Antonov An-124 to transport Buran-class orbiters, and only one example was ever completed. Yet the C5 plane has no comparison to the antenov
The only Antonov An-225 to be built was destroyed in the Russian-Ukrainian war
You are correct ✅ 👍
the enormous landing gear cna support the huge aircraft, because they are 1. under the aircraft, and 2. connected to the aircraft via huge metal things.
Thick SHAFTS 😮
"tested successfully" - yet the tires flatten during that maneuver
Yes, they are very important. If the planes can’t fly, what good is a pilot?
Do one of these on the BRAKES please.
Wow
Imagine the load on those wheels and the landing gear whn one of those big planes lands.
True. I always wondered why they didn’t spin the wheels up close to landing speed to cut down on touchdown friction. Maybe someone tried it and it didn’t work?
@@6thmichcav262 That's been studied to death over the last sixty years. Turns out to be a lot more trouble than it's worth, regardless of the spinup method employed.
Landing loads can actually be less than takeoff loads. What's not obvious watching a landing is that at touchdown, most of the weight is still being supported by the wing until spoilers deploy. Also, stroking of the shock strut serves to reduce peak loads.
@@marcmcreynolds2827 Thank you for addressing that question for me!
I thought the video would explain how the landing gear works
Me too. Just general stuff about planes really.
Nice video!!
With these skill sets and experience, these guys are still making military salaries..Great health care, free chow, subsidized housing, but if you were a civilian I bet the pay would be 40 an hour.

It's an airplane documentary that's very interesting to watch.
“This Boeing 747-8 is preforming what is called a rejected takeoff.”
- Airplane takes off…
Interesting & Informative Video
This is really awesome and informative
Have a good afternoon
Shurely beautifully parts of the plane..
That was a self-propelled Howitzer you called a tank.
Im pretty sure they stopped making the A380
It's hard to take you seriously after you claimed that the A380 "continues to be a popular option among major airlines", considering that Airbus halted production on the jet last year due to lack of customers.
It's consumes to much fuel, it's maintainance is more expensive than earning😅
Hello! This is about the tyres.. so shut up already.
I think you misunderstood the video... those companies mentioned are still utilizing the A380. The video didn't say the plane was flying off of the store shelves... so to speak.
@@ejkk9513 bro check 1 more time, today's only UAE use A380, most of airways companies stop using, they use their other models
@@ejkk9513 Are you implying that airlines routinely chose between jet models they have in their inventory to serve various routs on a routine basis?
"Hey Bob, which jet should we fly from New York to London today? The 737 or the A380?"
"Continues to be a popular option" is understood by everyone except you to mean that many airlines are choosing to purchase the A380 instead of other aircraft, which is obviously incorrect.
are you testing with the equivalent of full passengers and cargo on board?
Justamente por serem enormes é que eles suportam até mais do que 400 toneladas.
Good Stuff!
AMAZING
lmao.. "you trying to throw a part" the guy says to the dude using the 4 jaw chuck lol. love shop humor
Excellent video sir. I enjoyed it
Thank you!!
Very impressive
So, can landing gear support 400 tons? Through landing gears of different configurations. Got it. I thought sturdy tires and crazy air pressure might have something to do with it... my bad.
Pavement strength is what limits tire pressure BTW, to somewhere around 180 psi for larger airports. Going higher doesn't break the pavement instantly, but does wear it out faster over time via fatigue. Same idea as with metal fatigue, where the amount of load applied plays off against the number of cycles until damage or failure.
Do they consider passenger weight per person ? Some people, like football players weigh over 275 to 300 pounds each. I know lighter weight people ( like me ,175 ) , will average out total weight plane capacity. Does the plane roll over a scale before take-off.
@@michaelcesco2970 Scales might be used in special situations such as flight testing, and some airliners have built-in gear weight sensing.
What's typically used in classic Weight & Balance calculations, where no direct measurements are made, is an assumed weight for the empty aircraft, the fuel taken on, and passengers plus bags. That can be a number like 220 lb per passenger including bags.
I was once told that your (American) football players scenario is in fact what designs floor strength. For the aisle, where people actually walk, floor rigidity is also a consideration. Even if it's strong enough, a lot of flexing would be disconcerting.
The above is for normal-sized airliners. For the smallest commuter planes, e.g. Cessna twins, passengers may be individually weighed and then seated so as to insure proper balance.
From landing gear documentary transition to military documentary 🥱
3:50 burning brakes, what a stench !
The fact that the main parts of landing gear struts are hot forged titanium by VSMPO AVISMA Russia was ommitted here!
Avisma is the only company that has the technology and 75000 ton presses to forge such large titanium components
Boeing, Airbus, Embrair use Avisma
Safran receive components from Avisma and does the final machining.
Wingstrut forgings are also done by Avisma

"How These Enormous Landing Gear Can Support 400 Tons Aircraft" It is because they landing gear are "enormous".
i think 400 tons is pushing it for single landing gear wheel assembly, considering steel parts shatter under loads as little as 20 tons. Methinks that number is for the safety inspectors and regulatory organisations
Tudo é feito dentro da engenharia. Se foi feito i projeto dentro dos conforme do peso, tem que suportar 🇧🇷🇧🇷
Weird? I could have sworn "popular" meant there was a demand for the item. I didn't now the definition changed to quit buying and trying to get rid of. Interesting! Maybe you can do a video on how and when the word changed definition.
The Airbus 380 is so advanced that it is now in the scrapyard!
Good video.
ah yes, 400 tons aircraft
This is a good example of how you can spend 10 million dollars to get 2-3 millions in "savings".
"continues to be a popular option"
it is literally being discontinued because nobody wants them anymore
How come all the tires went flat after the brake test 4:17
exacto, pueden soportar precisamente porque son enormes.
Amazing
Wow amazing
would have been nice to talk about tires, I'm guessing there is nothing ordinary about them
Wow! I tell ya though I wouldn't want to be responsible for those parts.
I just love the background music at 4:48
It’s from Hidden Enigma
Just what is "100% wore out breaks"?
there are a lot of landing gears bigger than a 380 like C5A,etc.
I'm afraid to say that although the C-5 does have more landing gear legs and therefore more tires and brakes, the actual legs on the A380 are the largest of any aircraft that size; both the bodies and wings alike.
Take those planes down on of the streets in town. Winnipeg Canada and we'll see how long they last. Nice

And enables I BEAM slideout wider than fuselage, more stable too, more even distribution on different quality surfaces landing on, making less dangerous to less affecting steering on initial touchdown..varying surfaces... greater chance of survival.. bad conditions with variables..
Airbus has stopped the A380 program down.
¿Why?
