The “bird” towards the end of the video... 50+ years ago I bought a mechanical bird at a local fair. It was made of hollow plastic tubes as the skeleton with thin plastic film for wings and it was driven by a rubber band and it flew just like a dove! It got itself upwards and really high until it stalled. Then it tipped over forwards, beak down, still flapping. During the dive into a slight ascending bow, the air pressure became too high for the kinetic energy in the rubber band so without flapping it glided in a long gradually rising bow until it lost ascending acceleration. Then, at the end of each top of the rising curve it started flapping again. Just like doves fly! It caught a lot of attention I remember. More amazement amongst adults really. I was a young teenager at the time and so often later in life I regretted having tossed it away instead of keeping it for my children.
I copy and pasted your comment into ChatGPT and it said you were likely talking about a "Tim bird" or "rubber band powered ornithopter". Let me know if this is what you were referring to
Mine was immediately torn to bits by the family dog on its second flight after he heard it and went into bird dog mode,it was that convincing and realistic I suppose.
@@lasercat538 thx. Maybe it was. But looking at all pics on the web i think mine had more faded colours. Much like my memory 😅 but it could very well be that Tim bird toy. If that was around 1970?!..
A centrifugal compressor below a parachute type canopy can replace the common helicopter method of generating lift. This configuration is more efficient in how the kinetic energy of the air is converted into pressure below and even by suction above the canopy.
I like your format - a sequential, basic analysis of the technologies with their pros and cons, followed by a summary at the end. (Teaching 101, but almost entirely missing from the Tube-o-sphere). Your library looks interesting. Subbed. 😉
The company zipline has taken out a patent for a propeller for its drones that looks totally different than a regular propeller and is significantly quieter than regular propellers and looks a bit like a wishbone..
OK I'll play your game "Fly like a Bumble Bee at 8 Hertz" well at least hover. I'd suggest a light honey cone platform with Piezo in each cell to focus the already Focused Charge Shape that frequencies between 8 Hertz to about 9.5 Hertz create. To actually visualize what 8 Hertz looks like there's a guy on youtube that does 1 Hertz through to 10 Hertz over water and it's quite clear why Tesla himself Liked 8 Hertz. It appears like a Bulleye with 2 outer rings - Just like an Explosive Shaped Charge. If you have a hexagonal platform made of hexagonal tubes, and mount the Piezo wired in Rings to fire the piezo's in the firing first, the first ring firing second and the outer ring firing third is a continuing sequence at something between 8 and 9.5 pending on the resident of the length of each hex tube you will in fact make a hoverboard. How High and how controllable is going to be related to the strengths you play on the 6 segments. So Play Like a Bumble Bee and remember where you got it from. Me
Whatever the shape of the propeller, as long the profile of the blade meets the Bernoulli's principle, the propeller will generate lift to lift or propel force.
The screws were upside down and the thread needs to be stretched. A curtain around the screws could help funnel thrust. Just using these ideas should give you 3xthrust
look into T. Townshend Brown and his studies of dielectric stress, in the 1950s he was able to make a disk (capacitor) fly at hundreds of miles per hour. though his experiments were tethered. the tethering was due to high voltage needs to achieve the dielectric stress needed for flight. but it boiled down to this. pump enough electricity into a capacitor and you can achieve flight with no moving parts.
👍🏻 Interesting, but what about the V-configured propeller? 2 blades arranged in a V shape with a counter-balance opposite them .. supposedly very quiet
The company Zipline works on this technology and Mark Rober (UA-cam channel) made a video covering this recently (it is indeed pretty quiet as per his video)
When I built my jet drone. I used 1 turbine engine with just 6 pipes for exhaust. Each pipe was 28 inchs long and was what most call arms I guess lol. Gate opens and closes like carb to create direction..... or gain or lower height. Funny enough just used cheap pixhawk to control it with my own firmware
Your concept came into my mind as I saw the 4 expensive turbines on that drone. I guess that the current VTOL fighter jets don't carry so many jet engines on board to be able to maneuver in the air
@@pascalfust1035 well I literally have 11 engines 110lb thrust turbines all the same make lol. But here is the thing! 4 on drone is suicide for those engines. These small turbines dont like like up and down left to right. Greatly reduces bearing life. Forward only is ideal for how fast they spin. Other issue is the rotation mass of them causes really bad rotation issues. In a drone was huge problem for me. Ended up using 20mm tubing on left and right. On the right I had 16mm incerts just to restrict some thrust output Just to help with the twisting rill effect. So gyros could make it fly level. Gates where very hard to manage. Ended up using 6 align digital tail servos for 800mm 3d helicopter to control them has to be stupidly fast changes of the gates. Turbine lasted 50 hours in that drone build. Tossed a new one in it and it has been wall hanger ever since lol
the toroidal propeller shows more promise then was advertised here it has higher performance with less noise by a significant margin then standard propellers. the fact that it produces less noise contributes to its gains because instead of energy into making noise, it's more energy into thrust. with advancements in 3d printing the prices should keep dropping. it has a promising future.
Ionic water propulsion is quite interesting; salt water is best for good propulsion, but continuous feed of hydrogen being created by the separation of h2o is what in turn can be captured and used in a fuel cell to create energy for recharging the batteries.
If I had the money? This is what I would try. Using a drone: 1) Remove the propellers. 2) Using Mercury inside of a round tube in a figure 8 shape; folded back onto itself. So the fluid would flow in clockwise direction in the upper lever and flowing counterclockwise in the lower level. This would be using the magnetic field of the motors to move the Mercury in only one of the levels. As the other level needs to flow in the opposing direction. It is these opposing fields that break the gravity fields and allows the lift.
What about the Magnus effect, either with rotating tubes or spheres? There's also the possibility of using small graphene spheres, reinforced with internal struts with a vacuum inside.
What about the zipline drone blade design, which is formulated from soft feathered owl wings which is near silent for neighbourhood drone deliveries. P:S the design is totally alien to current designs.
Ion Propulsion has Hughe Potential if we figure out how to properly power it maybe with the help of ttesla coils that provide energy thru the air / atmosphere ...
The snail-propeller is just louder, heavier and less efficient. Toroidal props have been in use for decades but it is used for anything but efficiency (and for drones - yeah, if you adapt the prop and the entire drone than it can be quieter). Jet-drones ... no commercial aircraft uses turbojets. they are extremely powerful but inefficient. They are only used for military applications due to their shear power and the top-speed (turbo-fans have a hard time reaching Mach 1.5) Ion thrusters - no. Let alone the practical limits, even the theoretical maximum limits make them an absolute no-go for drones. They are horrendously inefficient and weak. There is a reason why props have not changed much for a long time, same for turbo-fans. The aviation industry is spending many billions each year for the smallest improvements and they (together with the military complex ) are also funding thousands of (mostly stupid) projects each year in hopes of seeing even glimbs of some new idea that could work. DARPA is a prominent example spending several billions each year on stuff like nuke-propelled rockets and robot-donkeys.
It's odd that I haven't seen that sideways drum rotor with ducting around it. Where the duct inlet is in the center, horizontal, and the outlet thrust is at the bottom. The duct would have to be able to rotate or in some way be able to move the thrust forward or backward around the cylindrical duct. It's an ID fan. In heavy industrial we use them to move air...a lot of air. If the whole thing could rotate a few degrees forward and back that could give you lateral movement or if the 4 "squirrel cages" pushed against each other it seems like the drone(or whatever) would be more stable. Then it would be less dependent on drum speed, or difference in drum speeds, to move laterally or tilt. I'm not a drone mechanic though. The thing would have to rotate to go a different direction I think. Damn, now I want to make one.
7:02 Again the same common mistake and misunderstanding. Those ions (not plasma) don't need to collide anything. It is just the matter of force and counter force: if you push an ion away you will be pushed to the opposit direction by the impulse (I=mv).
I had an idea for a craft(possible heavy lifter like an air crane) that uses a number of different lift effects. Its a large neutral buoyant hydrogen filled lifting body with variable geometry tech and cyclorotor powered. It would be hydrogen feul cell powered. Imagine a massive manta ray shaped craft with wings that change shape to maximize lift potential, hydrogen gass bags make it light but not lighter than air.cyclorotors under the main body would give the main thrust and maneuverability.
Until someone can review the Zipline propeller revealed in Mark Rober’s last video, nothing else matters. That thing is revolutionary and there’s essentially no other info out there about it.
Yeah, but also it can be used for horizontal flight, fast as airplane. And if you add plane wings to cyclorotors - you get plane with vertical takeoff and landings, which doesn't longer reqire any runways.
Why has no-one tried a semi floating drone, one with a small balloon to offset some but not all of the weight? I realise it would add to the drone's wind profile, but it would give a longer flight time.
You folks are killing it with your videos! 🚀 Each video is a tech journey that I'm excited to take. Keep up the fantastic work, and know that your viewers are hungry for more! 📚🎥
5:24 Seems to me you'd be burning through a million cycles in just a few days at best, when you consider the wing beats/second a small flying craft requires. The average hummingbird has a wing beat of around 53 hertz. At that rate, you'll have about 48 hours of use. Now, if you use that in craft with much lower wing beat speeds, it's a little better.
For those who want to look at the ionic drone more, the name is Ethan Krauss. It sounded like it was pronounced "Cross" in the video, but as I found out, Ethan Cross has nothing to do with ionic drones!😆
💥💥💥💥💥💥💥💥💥💥The principle of the railgun underlies the unusual design of the aircraft, but it is rarely talked about because it is a secret thing. The topic of pulsed plasma engines has been known since the early 1960s (see PPT - Pulsed Plasma Engine in Wiki) - they are usually designed for spacecraft. But I will tell you about a little-known design - plasma propulsion panels for vehicles flying in the atmosphere, they use the same pulsed plasma engine, but reduced to the size of a pencil and stacked like cells in the panel. The design is similar to the screen of an ordinary plasma TV, because there are also bit cells there to activate the glow of pixels on the screen. And in plasma propulsion panels, the discharge cells are long, the spark gap has the architecture of a railgun (just rail contacts or coaxial), and the ionized discharge air is accelerated there by the Lorentz force to enormous speeds - a kind of ramjet engine is obtained. Just imagine! - tens of thousands of small ramjet engines assembled in a panel and synchronously firing plasma at a huge frequency (hundreds of kilohertz). Thus, plasma propulsion panels create lift with the help of pulsed emissions of plasma jets from the cells of the railgun - a huge impulse is obtained, and the plasma twists the air into toroidal rings - the aircraft is supported on this air cushion. Horizontal acceleration is created by the same plasma panels on the sides of the device (they glow, from the outside they look like "portholes"). Devices such as the "triangle" or "disk" have been observed for a long time, they are mistaken for aliens - but these are terrestrial devices. They are classified and used for espionage and secret activities. Pulsed electromagnetic technology generates microwave radiation, so it is harmful to health, so they rarely fly - only on military missions. And for a citizen, therefore, they are not suitable. Declassification has now begun - too many people know about this secret technique. After declassification, they will be used for cargo airships.🕳🕳🕳🕳
Kind of curious, why would you say that in the future it is very likely that micro aerial vehicles will have some different type of setup? It's certainly possible to generate lift with other designs and methods, but is there anything more power efficient or weight efficient?
I find it surprising you never mention how loud jet engines are. Just price and availability. Yet you listed noise concerns when referring to different props.
Hi everyone, thank you for this feeds and comment sections. I guess its almost true you mentioned there is a flaw in the diagram and designs, that wasn't done in purpose, its incomplete diagram. But I just leave it there so incase the designs gets stolen, it wouldn't work.
You missed a few innovations, on your other videos, and that chanel that has many bladed 350mph+ drone designs. That's crazy stuff. Moving over to vtl and pv aircraft, there is one based on the Dyson fan technology. There is a single prop alternative to private corporate jets, with linear design. There is a drone for deliveries that has a delivery box with 400 feet cable to drop the parcel on a dinner plate sized area. It's propeller system is very quiet and likely very efficient. It on the same channel as the African drone blood delivery service that has launcher and dual arm capture. 500,000 deliveries in 6 years to hospital from the central base. I think both are the same guy who designed them. Have a great day.
The company is Zipline, founded by Keller Rinaudo Cliffton. I don’t know if they have their own UA-cam channel, but Mark Rober's video on them is worth a watch.
We as humans always feel what we have and are used too, is the way it will be for some time. Yet history tells us things change, so let's think outside the box and embrace new thinking. for example and only for example, could we have a propellor with ion propulsion combined! Would ions change the boundary layers around a prop in a way that would add an increase in displaced mass. All of which i expect will be shot down by very cleaver experts; and that is OK, yet please just remember: - some of the best thoughts come from thinking like a wild man outside the box of rational processes, and you never know what one thing will change the World. To end I loved the video, it is very interesting so please keep them coming.
Though I envision drone warfare as more of a nightmare than as lower-casualty "dream warfare", I understand that others' drone uses mandate that we stay competitive. We need to ramp up cyber education en-masse (& funding thereof) beyond just UAV engineering, production using domestically-acquired (per country) materials, and applications, but also related diversification of methods for detecting and targeting specific coordinates. Annnnd, as if that weren't enough, any "cyber-army" must thwart attempts at proximal and distant hacking (incl data retrieval, data swapping, destructive sabotage, imbedding code ... incl live-time reprogramming - esp of moving objects, turning on built-in geolocation +/- audio-visual +/- broadcasting functions, Etc.) for ALL digital technology with abuse potential throughout our country (+/- cooperate internationally to disband coordinated networks of offenders). Then there's the need for oversight to limit abuses of such power. Nontrivial! ... Btw, have you heard the Ted-Talk UA-cam video wherein Elon Musk enthusiastically suggests how convenient it would be to integrate his NeuraLink Company's neural lace (hardwired into customers' heads) with the IoT (Internet of Things), likely controllable via his Starlink Company's global network of low-orbiting satellites?
The smaller the tech becomes that civilians want UAVs to carry, the less efficient drone propellers need to be. Luckily, small sodium batteries are around the corner. Audio & visual is shrinking. Unfortunately, diversified location tech (detecting and targeting), that's less EMP- vulnerable, has yet to evolve in sufficiently diminutive combination tech. Of course, better propellers extend range, extend the life of materials by reducing cavitation "explosions", and minimize energy consumption from production "footprint" as well as from driving UAV motors +/- accessories (all of which impact climate, incl even solar-powered friction "thermal pollution").

Research why humpback whales have bumps on their flippers. Efficiencies at low speeds? The same with bulbous bows on modern vessels. Think experiment think.
Jet engines have high temperatures inside them as a consequence of COMBUSTION of the fuel. 3D printers using plastics aren't going to be of any use printing jet engines !
Liquid die-electric Good god we've managed to develope reactive tendons.......well more of a muscle/tendon combined, it's insane knowing we are a few years away from creating a fully non-organic lifeform, that bird is close to being an actual bird
Has water cavitation research been revolutionizing propeller engineering that's accessible to civilians (for drones & wind-power harvesting, Etc.) who don't use 3D printers?
You need to do some more research. The torroidal propeller you show attached to the marine engines was invented in 2012 by Gregory Sharrow and he now holds 78 patents on it. Although very expensive, it has shown to be superior to conventional props at almost every metric including speed, fuel consumption and vibration.
It's not rocket science. I'd like to see drones powered by gasoline engines. Drones could be designed after heavy lifting helicopters, dual rotor helicopters and blimps.
I wouldn’t say we can do multi-material 3D printing but there is a company I can’t quite remember the name of printing rocket engines fuselages all the parts you would need to send a payload to space so we can’t be far away from printing jet engines right 🤔
I have the same problem, you gobble thru Berkeley and the blah blah ion thrust then when trying to follow can't get the sub text to work, grr if you have something to say work on your sound system...we are interested...
Toroidal props are not new. They have been around from the earliest use of powered craft. Old enough to have been used a plot device in a 1940's movie.
And jet engine powered drones can fly longer than 10 minutes. Drones and other rc aircraft were stupid expensive for my entire life until 10 or so years ago, so if the market for small jet engines increases then the prices will drop. And at the moment you can get one of these engines for around $1500
if only people could replicate tehTR3B anti grav effect engines. fast moving dense vortices are what nature creates to counter gravity as observed in tornados.
Циклические воздушные колёса могут стать новым словом в авиации, так как могут позволить летать на больших скоростях горизонтально, как самолёты, только используя поворот направленности роторов. Это позволит уменьшить затраты энергии на горизонтальное перемещение относительно горизонта, так как сопротивление корпуса потокам воздуха можно снизить именно с целью дальних полётов. А если добавить в конструкцию крылья, то это получится самолёт с вертикальным взлётом и посадкой на горизонтальные и наклонные плоскости.
This video is just an overview of different drone propulsion systems which I covered before! Thanks for watching!

Could you take the "Flying Screw" and slot it so it is is like a prop, so cut openings in it, at intervals....

A centrifugal compressor below a parachute type canopy can replace the common helicopter method of generating lift. This configuration is more efficient in how the kinetic energy of the air is converted into pressure below and even by suction above the canopy.
Variable pitch propellers with curved blades, That's probably the way to go, they're pretty damn efficient....

Put the Da Vinci screws under the drone and eliminate downwash, and create efficient ground hover.
That will actually just pull the drone downwards
You cant eliminate downwash. Thats how you fly. By displacing air downwards...
I didn't get much out of this. I think propellers question is settled.
Until someone can review the Zipline propeller revealed in Mark Rober’s last video, nothing else matters. That thing is revolutionary and there’s essentially no other info out there about it.
The cyclorotor gives me similar vibes as a helicopter. Very complex, but it performs its "gimmick" very well
Yeah, but also it can be used for horizontal flight, fast as airplane. And if you add plane wings to cyclorotors - you get plane with vertical takeoff and landings, which doesn't longer reqire any runways.
The propeller came from a Chinese toy. DaVinci stole the idea.
Ion propulsion… Looks a little bit like a flying saucer
They're using iotics restoration on most of the satellites are coming out. Most recent years
Lol 😂 500 years ago stolen work from India
Why has no-one tried a semi floating drone, one with a small balloon to offset some but not all of the weight? I realise it would add to the drone's wind profile, but it would give a longer flight time.
You folks are killing it with your videos! 🚀 Each video is a tech journey that I'm excited to take. Keep up the fantastic work, and know that your viewers are hungry for more! 📚🎥
3:28 So it seems Hobgoblin is real, so my question is: Where is Spiderman?
zipline drone has anther propeller that seems good
5:24 Seems to me you'd be burning through a million cycles in just a few days at best, when you consider the wing beats/second a small flying craft requires. The average hummingbird has a wing beat of around 53 hertz. At that rate, you'll have about 48 hours of use. Now, if you use that in craft with much lower wing beat speeds, it's a little better.
Liquid dielectric is best
For those who want to look at the ionic drone more, the name is Ethan Krauss. It sounded like it was pronounced "Cross" in the video, but as I found out, Ethan Cross has nothing to do with ionic drones!😆
Im telling you! Birds are not real.
toroidal props are awesome!
💥💥💥💥💥💥💥💥💥💥The principle of the railgun underlies the unusual design of the aircraft, but it is rarely talked about because it is a secret thing. The topic of pulsed plasma engines has been known since the early 1960s (see PPT - Pulsed Plasma Engine in Wiki) - they are usually designed for spacecraft. But I will tell you about a little-known design - plasma propulsion panels for vehicles flying in the atmosphere, they use the same pulsed plasma engine, but reduced to the size of a pencil and stacked like cells in the panel. The design is similar to the screen of an ordinary plasma TV, because there are also bit cells there to activate the glow of pixels on the screen. And in plasma propulsion panels, the discharge cells are long, the spark gap has the architecture of a railgun (just rail contacts or coaxial), and the ionized discharge air is accelerated there by the Lorentz force to enormous speeds - a kind of ramjet engine is obtained. Just imagine! - tens of thousands of small ramjet engines assembled in a panel and synchronously firing plasma at a huge frequency (hundreds of kilohertz). Thus, plasma propulsion panels create lift with the help of pulsed emissions of plasma jets from the cells of the railgun - a huge impulse is obtained, and the plasma twists the air into toroidal rings - the aircraft is supported on this air cushion. Horizontal acceleration is created by the same plasma panels on the sides of the device (they glow, from the outside they look like "portholes"). Devices such as the "triangle" or "disk" have been observed for a long time, they are mistaken for aliens - but these are terrestrial devices. They are classified and used for espionage and secret activities. Pulsed electromagnetic technology generates microwave radiation, so it is harmful to health, so they rarely fly - only on military missions. And for a citizen, therefore, they are not suitable. Declassification has now begun - too many people know about this secret technique. After declassification, they will be used for cargo airships.🕳🕳🕳🕳
Kind of curious, why would you say that in the future it is very likely that micro aerial vehicles will have some different type of setup?
It's certainly possible to generate lift with other designs and methods, but is there anything more power efficient or weight efficient?
I find it surprising you never mention how loud jet engines are. Just price and availability. Yet you listed noise concerns when referring to different props.
Hi everyone, thank you for this feeds and comment sections. I guess its almost true you mentioned there is a flaw in the diagram and designs, that wasn't done in purpose, its incomplete diagram. But I just leave it there so incase the designs gets stolen, it wouldn't work.
You missed a few innovations, on your other videos, and that chanel that has many bladed 350mph+ drone designs. That's crazy stuff.
Moving over to vtl and pv aircraft, there is one based on the Dyson fan technology.
There is a single prop alternative to private corporate jets, with linear design.
There is a drone for deliveries that has a delivery box with 400 feet cable to drop the parcel on a dinner plate sized area. It's propeller system is very quiet and likely very efficient. It on the same channel as the African drone blood delivery service that has launcher and dual arm capture. 500,000 deliveries in 6 years to hospital from the central base. I think both are the same guy who designed them.
Have a great day.
The company is Zipline, founded by Keller Rinaudo Cliffton. I don’t know if they have their own UA-cam channel, but Mark Rober's video on them is worth a watch.
My favorite flying object was Superman, although I have no idea what propulsion system he used.
We as humans always feel what we have and are used too, is the way it will be for some time. Yet history tells us things change, so let's think outside the box and embrace new thinking. for example and only for example, could we have a propellor with ion propulsion combined! Would ions change the boundary layers around a prop in a way that would add an increase in displaced mass. All of which i expect will be shot down by very cleaver experts; and that is OK, yet please just remember: - some of the best thoughts come from thinking like a wild man outside the box of rational processes, and you never know what one thing will change the World.
To end I loved the video, it is very interesting so please keep them coming.
Thanks for doing your voiceovers! I'm still loving your videos!
So that’s how the alien’s designed the ufo … IT ALL MAKES SENSE 😂😂😂
1:49 - the cyclorotor works by celebrating fluid with a...? Who is writing this stuff?
please give me pointers on a propulsion system for a drone which will work in space where there is no atmosphere or gravity. I appreciate your help
Now add torsion drives to the drones and the propulsion system will be enhanced. Skunkworks already proved the concept.
Do any of these new prop designs have any applications for a two stage snow blower ?
Nothing that was said about the toroidal prop was true. Ive tested and reported the results extensively
Though I envision drone warfare as more of a nightmare than as lower-casualty "dream warfare", I understand that others' drone uses mandate that we stay competitive.
We need to ramp up cyber education en-masse (& funding thereof) beyond just UAV engineering, production using domestically-acquired (per country) materials, and applications, but also related diversification of methods for detecting and targeting specific coordinates. Annnnd, as if that weren't enough, any "cyber-army" must thwart attempts at proximal and distant hacking (incl data retrieval, data swapping, destructive sabotage, imbedding code ... incl live-time reprogramming - esp of moving objects, turning on built-in geolocation +/- audio-visual +/- broadcasting functions, Etc.) for ALL digital technology with abuse potential throughout our country (+/- cooperate internationally to disband coordinated networks of offenders).
Then there's the need for oversight to limit abuses of such power. Nontrivial!
... Btw, have you heard the Ted-Talk UA-cam video wherein Elon Musk enthusiastically suggests how convenient it would be to integrate his NeuraLink Company's neural lace (hardwired into customers' heads) with the IoT (Internet of Things), likely controllable via his Starlink Company's global network of low-orbiting satellites?
The smaller the tech becomes that civilians want UAVs to carry, the less efficient drone propellers need to be. Luckily, small sodium batteries are around the corner. Audio & visual is shrinking. Unfortunately, diversified location tech (detecting and targeting), that's less EMP- vulnerable, has yet to evolve in sufficiently diminutive combination tech.
Of course, better propellers extend range, extend the life of materials by reducing cavitation "explosions",
and minimize energy consumption from production "footprint" as well as from driving UAV motors +/- accessories (all of which impact climate, incl even solar-powered friction "thermal pollution").
subscribed = thank you for a well edited script and decent HUMAN narration.
Also thank you for NOT making the presentation ALL about your face like so many others who are perpetually suck in the 2004 narcissistic vlogger style of constantly mugging, goofing and pretending to be an actor
A nuclear battery that was safe and reliable to use could be used in those ion thruster vehicles because it would be a good weight to power ratio.
See... Electric motors using Hydrogen Solar Cells... Will change flight time for Drones to crazy levels when done right!
None of these are “breakthroughs” 🤨. All KNOWN systems, only difference is computing advances to control them better in flight cause they suck w/ out.
Research why humpback whales have bumps on their flippers. Efficiencies at low speeds?
The same with bulbous bows on modern vessels. Think experiment think.
Jet engines have high temperatures inside them as a consequence of COMBUSTION of the fuel. 3D printers using plastics aren't going to be of any use printing jet engines !
Liquid die-electric
Good god we've managed to develope reactive tendons.......well more of a muscle/tendon combined, it's insane knowing we are a few years away from creating a fully non-organic lifeform, that bird is close to being an actual bird
Has water cavitation research been revolutionizing propeller engineering that's accessible to civilians (for drones & wind-power harvesting, Etc.) who don't use 3D printers?
You need to do some more research. The torroidal propeller you show attached to the marine engines was invented in 2012 by Gregory Sharrow and he now holds 78 patents on it. Although very expensive, it has shown to be superior to conventional props at almost every metric including speed, fuel consumption and vibration.
Toroidal propellers have already been breaking industry standards??? Why would a prop that can be 3D printed not be used???
It's not rocket science. I'd like to see drones powered by gasoline engines. Drones could be designed after heavy lifting helicopters, dual rotor helicopters and blimps.
I wouldn’t say we can do multi-material 3D printing but there is a company I can’t quite remember the name of printing rocket engines fuselages all the parts you would need to send a payload to space so we can’t be far away from printing jet engines right 🤔
3:47 This specific Ionic truster doesn't produce plasma. Please go back to school and learn basic Physics.
I have the same problem, you gobble thru Berkeley and the blah blah ion thrust then when trying to follow can't get the sub text to work, grr if you have something to say work on your sound system...we are interested...
No shout-out to Zipline's quad props? Mark Rober did a review on them and they are funky and quiet.
Toroidal props are not new. They have been around from the earliest use of powered craft. Old enough to have been used a plot device in a 1940's movie.
Mark Rober's video from Zipline seems to show they have found a pretty good solution to the noise....
And jet engine powered drones can fly longer than 10 minutes. Drones and other rc aircraft were stupid expensive for my entire life until 10 or so years ago, so if the market for small jet engines increases then the prices will drop. And at the moment you can get one of these engines for around $1500
Let's see the Nokola Tesla wireless antigravity models like they run on AlphaCetalon3, the aliens there swear by them!
if only people could replicate tehTR3B anti grav effect engines. fast moving dense vortices are what nature creates to counter gravity as observed in tornados.
Циклические воздушные колёса могут стать новым словом в авиации, так как могут позволить летать на больших скоростях горизонтально, как самолёты, только используя поворот направленности роторов. Это позволит уменьшить затраты энергии на горизонтальное перемещение относительно горизонта, так как сопротивление корпуса потокам воздуха можно снизить именно с целью дальних полётов. А если добавить в конструкцию крылья, то это получится самолёт с вертикальным взлётом и посадкой на горизонтальные и наклонные плоскости.
I'm curious to whether or not ion propulsion engine would work in 0 gravity I don't believe it would but I'm not sure
Very poor audio. The speaker is talking too fast and does not clearly pronounce his words. Slow down and speak clearly.
Some props need to be given to American Anti Gravity who did ionic lifters for many years using a mains power cable attached to the lifter platform
