As a frenchman i say hell yeah to that ! 🤣
I can imagine an ornithopter working as a really tiny insect sized drone designed to infiltrate buildings. I cannot imagine it working as a normal sized drone or even aircraft due to air density, mechanical stress and gravity.
If I'm correct. The wing tips would be super sonic.
This reminded me of the hunter-killer scene in the movie.
Ornithopters can at least scale up to normal drone sized. For example, the various robot birds and bats Festo has made over the last few years.
There are ornitophter drones. 😅 They actually can fly far longer because of the gliding affect. 🤷🏻♂️ if you don't believe me, there's one that looks like a parrot that I believe broke a flight record. 😅 I could be remembering incorrectly.
@@JDubzDrumzI think that he might be referring specifically to the dragonfly style design rather then any design with flapping wings.

Underrated comment
2:00 im pretty sure a normal plane with a propeller would use far less energy than trying to flap 4 big wings at hi speed
Looking at nature, Hummingbirds require insane amounts of sugar to stay alive too. Especially compared to otherwise similar birds that flap normally.
Modern ornithoper prototypes in lab settings do actually appear to offer superior efficiency to propeller driven aircraft in certain situations, like at lower airspeeds. I don't know if their testing methodology is completely bulleproof because ornithopters are a really weird mix of biology and aero engineering and judging their effectiveness without a very sound understanding of both is hard, but their performance is at least comparable. The real advantage appears to be that you can achieve similar performance to a fixed wing prop plane while also being able to take off and land vertically.
@@jerrymartin7019 you mean like if everything is set to the opposite so less efficient means more efficient then yeah ok i agree, also you have herd of a helicopter or a V 22 osprey right? if not, these 2 aircraft can also take off and land vertically, id also like to add that if it were possible for birds to have propellers they would because it just makes more sence

@@theumbreon1.0 yes, a bit more than that since my soul is chained
the problem with these type of aircraft is a dragonfly doesn't scale nicely. We as human's weren't destined to fly, and lifting our weight into the sky takes a lot of effort. Thats why propelling hundreds of us im metal tubes needs a pair or two of big engines to do so. The mechanics of an ornothopter just doesn't scale. theres lots of moving parts that can easily break down either from metal fatigue or simple failures such as a busted linkage etc. Plus it would be a horrificly uncomfortable ride; with all that vibration being mechanically linked to the fuselage.
100% this
100% my thoughts. Scaleability is always the biggest hurdle. + how do you steer it? how do you even create lift with it just flapping up and down. Pretty sure a dragonfly can also rotate it a little in the axis n stuff. Biology is complicated and introducing so many moving parts its just inefficient.
Could see this as a real craft used by special forces in military, IF it can be made like the one in Dune, but cant see it ever being used as a passenger airplane
@@elmeril2203 Imagine being a soldior in the thing though. Those wings beating up and down, transversing from up stroke to down stroke (to actually generate any useful lift) would make for a very uncomfortable ride! I'd rather spemd my time snoozing in a C130 than being shaken half to death in a flappy plane :)
Exactly, this design at the scale in this movie will never happen. Too complex, materials that can't take the insane fatigue cycles, the need for extreme vibration cancelling measures. It's ridiculous especially when other flying craft designs could accomplish the same or better flight with less complexity and greater reliability.
5:17 An experimental French ornithopter turning itself into a 'windmill' before the German invasion was definitely an omen.
You’d be surprised by how many crazy French designs made it into today’s day to day life, to the point we don’t even think about it.
From the jet engine, designed early last century when airplanes where made out of wood and fabric and that today powers airliners and fighter jets, to the statoreactor (ramjet), the pulsoreactor that powered the V1s, the quadrocopter that today everybody flies under the form of drones, the automobile, etc…
Flapping or oscillating Wings on aircraft are like legs on land vehicles. We know how they ought to work, but we do not know how to make them survive working or power them to operate them for a useful amount of time.

I always find the way you said "Orthinopter" rather than "Ornithopter" is hilarious :D
Orthinopter sounds like an aircraft powered by bone 🦴
Fun fact according to the Dune lore, ornithopters are powered by a giant living mollusk bred to flap the wings
like a cartoon
lmfao he said orthinopter lmfao
Ornithopters are such a cool concept
I think they'll make a come back. They clearly work but now we have the solid state autopilot and stability control systems to make it work as well as high power electric motors for control of wing flapping, articulation and warping. They will be VTOL and very quiet.
@@williamzk9083 not sure about that, they would be less efficient, a lot more stress on the moving parts and who knows how loud it would be because there isn't a full scale working version
@@williamzk9083
Energy efficiency and the ridiculously high inertial forces at the wings with every direction change at this speed negate your idea
Thats why you dont see this on larger animals.
@@alphadawg81 pterodactyls with wing spans of 10n/33ft and 250kg flew and leaped into the air. Only minimal Stresses would be involved. The inertia of the gentle downwards propulsive beat is arrested by aerodynamic lift itself. The wing then twist and rises gently under its own lift till at the top of the stroke when it descended da again. There would be no huge forces at the shoulder Joint
@@williamzk9083The bigger an animal, the less it flaps. For good reasons. Large Pterosaurs would have hardly flapped in flight mode.
Pairs of counterbalanced "fixed-blade" wings, which oscillate upon a desmodromically driven crankshaft, will be more efficient both mechanically and in terms of weight, and will be substantially more manageable/reliable/durable, than a hinged or split wing ornithopter. Utilizing greater quantities of smaller wings and an additional axis of oscillation should further improve effective output, as the winglets form a larger "dynamically ducted" wing, and reduce losses to aerodynamic drag by "slicing" upwards into the air, and "beating" downwards against the air.
Thanks, but I think you need to provide us with a diagram of what you just said. 😅
I wish I spoke engineer but sounds awesome
or you're totally wrong and wings actually work worse in air agitated by other wings ahead of them... which is what real life aircraft and racing cars' spoilers show to be the case. 😒
ornithopter wings certainly do need to change pitch or be flexible to change pitch by yielding to air resistance, more on the upstroke, which seems to be one of the things you're suggesting, without that, an ornithopter is entirely hopeless. insects generally fly that way, as do hummingbirds (the latter are the flying animals most easily replicated in simple hovering flight by ornithopters). some birds and I think more so bats fly mostly in a sort of butterfly stroke swimming like motion that involves complex folding of the wings to pull them forward, which would be very difficult to replicate. and many like small songbirds actually use a really strange looking standard flying pattern in which they flap a few strokes to propel up and forward, then tuck their wings in and arc a bit up and then down again like a little torpedo, so they bounce up and down. ai reckon it's probably an adaptation that they're evolved to basically do for fun, while it serves the evolutionary purpose of being more difficult for a surprise attack from an aerial predator like a falcon to hit them.
Desmodromes. I haven't heard that word since college....and a Ducati brochure talking about their desmosedice engine 😅
we need Thunderf00t in on this
It looks like a dragonfly but made out of steel. Interesting but clever design for a plane.
It seems to copy insect rather than bird flight as its name 'orni' would suggest.
except it doesn't work whatsoever, so there's nothing clever about it.
@@Ass_of_AmalekOrnithopters do work and do fly.
@@williamzk9083 at human scale the best are absolutely terrible compared to propeller- or jet-propelled aircraft.
@@williamzk9083no, not this type. Do you realize the forces at the end of the tip? The longer the wing, the faster the tip would be moving-physical limits exist. This only works at small scales-there’s a reason why no flying organism larger than ~a hummingbird uses this mechanism for flight. Material science isn’t even close-you not only have to consider the forces, tensile strength, but also heat. Can you imagine how hot the tip of the wing would get?
Flapping like an albatross, maybe, not a dragonfly.
The shockwaves of the wing tips continually breaking the sound barrier would cause such vibration that any known material would never withstand this.
it'd be basically the Thunderscreech all over again, except instead of a single (quite short, stout and rigid) propeller moved by a double engine connected to a single shaft, it'd be four independent wings with either two or four engines on a crank to move the wing up and down. Forget the vibrations on the wing itself, not sure any sort of engine would be able to withstand the stress of having to move a whole ass wing at basically supersonic speeds without wanting to jump out of the fuselage
There have been a couple of prop driven designs whose propeller tips broke the sound barrier. The engines didn't explode, but the pilots suffered constant severe headaches from being bombarded by dozens of tiny sonic booms all the time.
@@lukedogwalker a single design, the Thunderscreech, and it literally rattled the plane loose after a single hour of flight... assuming the test pilot could withstand the nausea that long
@@DonPatrono I thought there was also a variant/prototype of the Wyvern that this was tried with, but was abandoned.
@@DonPatrono the Tu-95's blade tips exceed the speed of sound. There's a reason it's infamously loud.
the biggest benefit of elastic wing tip is that airbus don't have to pay extra for extra wide terminal. The price gone through the roof even if you wing span a few feet too wide. A lot design consideration end up need to accommodating airport pricing instead of pure aerodynamic performance.
in the dune lore, the ornithopter's power actually comes from a clam opening and shutting rapidly inside the aircraft
I don't know enough about Dune lore to say if that's true, but I know enough to say it's entirely plausible.
Lolwut?! I don't remember that
This sounds totally plausible from someone who tried reading dune at too young and age and gave up
French challenge: dont go crazy (extreme difficulty):
5:32 the ornithopters folded itself into a swastika
It truly was a french plane ahead of its time. It surrendered before the war even started!
And I was always under the impression that insects like dragonflies and bees had one set of wings that they used for propulsion and one set of wings that they use for directional stability and changes.
Huh, thank you. TIL that bees in fact have 4 wings and not 2 that I, mistakenly, had assumed.
Flies have two wings. The other two have evolved into club like appendages.
@@kentl7228

@@AssistantCoreAQI Incredible little animals in ways, and we spray and swat them.
Between this ornithopter and the exaggerated tumblehome design of their pre-dreadnought warships, I have concluded that France is a Jules Verne fever dream.
Oh yeah, vibration would **obliterate** those wings in moments.
No matter what it's made of. Unless it's self-repairing, it's gonna experience a ton of stress fatigue very quickly
It all started with James Pitts' "Sky Car" vibrating orthotopter umbrella, then the umbrella was closed with a dome and devices appeared according to the scheme of conventional electromagnetic vibrating speakers (membrane + inductance) - fragments of the membrane were found by a farmer in Roswell. Then they created piezoelectric thrusters, or with small dischargers on the surface (they glowed all over the body due to ionization of the air), and now they are planes with plasma propulsion panels (so they are angular - that is, with flat surfaces). Thousands of discharge cells are densely packed into motor panels - they shoot streams of plasma (railgun architecture - coaxial electrodes). The ionized air of the spark discharge is accelerated in the railgun chamber by the Lorentz force to enormous speeds - a kind of ramjet engine is obtained. 💥💥💥💥💥
This is definitely your best video yet! I like how you looked at what worked in the old one as well as what didn't work. And then showed us how nature is being integrated into future aircraft design.
Please make a video about flying AutoGyros. They are an overlooked underused technology.
one fundamental flaw alot people had with this concept:
nature teaches us the fast flappers are all small and have no weight, insects or colibris.
all heavier ones flap slow.
Its really hard and against physics to try to apply small/weightless principles to a completely different scale.
the austrian and canadians did the right thing and used the right principle for this scale.

Man i love ur videos and you have rekindled my interest in aviation and other weird things!!! These videos keep me occupied and enthralled for hours on end well done you deserve a subscriber and keep up the good work!!!!
The bird of pray would be cool. But could you imagine the panic of a nervous flyer, with the outer wings of the albatross, and probably why it was named after that bird too. Has the four times 20 living people panic thinking the wings are falling off lol. I would not like to be on it.
"energy SAVINGS???"
Uh, no, No and HELL NO!
Do you have any idea how much energy is lost from flapping wings every time they're switching movement direction?
Ridiculously much.
And the same switch also causes massive force un the wing. Chances are BAD that wings will snap. Just as the French prototype did.
And the problems becomes exponentially worse with every increase in size.
To have any chance of working beyond micro scale, you also need to figure out how to not lose a huge amount of lift from every upthrust of the wings.
Personally, if i wanted something fictional-ish with these kind of abilities? I'd much rather go with Airwolf.
At least there, i can sort of figure out how to make it(supersonic helicopter) work in theory even if it's probably impossible in practice.
Imagine the tinnitus from that sound
9:30
Imagine being kinda scared of flying, braving it, looking out the window at altitude and seeing the wingtips flap around wildly
The speed required by the flapping wings at this scale exceeds the speed of sound, which is impossible without breaking those wings. Microscopic drones are, on the other hand, perfectly feasable, imitating dragonflies.
Is it just me or does he keep saying "Orthinopter"? Check near 3:40
It wouldn't be Found and Explained without him mispronouncing something important.
In the 60's, we had balsa wood gliders with nose-weights to throw and balsa wood gliders with rubber bands to twist a propellor and store energy, then throw.
As an Army Brat, my family was in W. Germany a lot. Toy stores over there had this rubber band-powered cellophane bird that would flap around in the air for a few circles.
Pretty cool take on the rubber band-powered flying machine, imho, back then.
I guess the toy was basically an ornithopter...
I would thing rather than flex the wings would twist, on the down stroke they would be flat but on the up stroke the trailing edge would passively twist down, that would have the result of making them act like a propeller on the upstroke but lift on the down stroke. Mechanically this would be simple to implement and would put far less stress on the materials, though it would make it very loud as because the the bearing for the twisting motion would have to have have probably spring loaded stops to limit the movement.
As others have said: "Sounds good! Doesn't work."
Take a look at the rubber powered toy ornithopers available all around the world. They stay aloft for a fraction of the time that a rubber powered fixed wing toy plane does.
Large flexing structures like flapping wings would put large stresses on the aircraft.
The flapping mechanism would be far more complex and delicate than a helicopter's rotor's hub.
In short it would be an underpowered, overstressed, maintenance nightmare used to duplicate things that we already have working fine.
But, it Would look cool in CGI videos...
I was just reading about the UTIAS Ornithopter recently. The bouncing up and down you mentioned near the end of the video is definitely an issue, especially at takeoff. Wings go down, fuselage lifts up, wings go up, fuselage slams down into the pavement. The landing gear is strong enough to take that, but it still lost a bit of speed every time that happened, which is why they needed to add a (very small) jet engine to finally make it fly.
Should be less of an issue with the French one though. Two sets of wings moving in opposite directions would counterbalance each other.
can you do a video of the Coanda 1910 jet biplane? the first "jet plane" before ww1. It was made by the same guy who discovered the Coanda effect.
Idk how will those wings for thos props materials would be but i have a feeling this is where graphene shines so well..
We finally have it the french version of Dune, Fune. Featuring a giant baguette worm
I'm in toronto right now, and It's pretty rare for a project like THIS to happen near me.
Look at the hoops people will go through to simply not design a helicopter.
I'm starting to feel bad for the helicopters.
Ornithoptors will never be used as war-machine because the wing flapping will create too much noise and it will be less efficient. 👍
But birds tho
@@FoundAndExplained the way bird flies, it would create too much pressure on the pilot. But if controlled remotely then,it could be useful but the production cost would be a pain.
birds are a lot lighter, so materials just arent up to it at our scale. yet. besides, we have jet engines.@FoundAndExplained
Flapping wing aircraft must be a maintenance nightmare.
Ornithopters are really cool, I am a huge nerd in early aviation and not once have I ever heard of this craft!
Aeronautical engineer here:
The biggest problem with the ornithopter is the acceleration that the wings will have, and the inefficience of the design
Il a regular aircraft, the wings will endure only lift, a mostly continuous force that will create constraint not varying over time.
In an helicopter, each blade will endure much more forces, mostly centrifugal. The lifting forces will also change slightly over the course of one rotation, but it will not create that much constraints. Finally, the rotor being balanced will reduce the efforts on the bearings of the blades. But overall, helicopter blades suffer way more than airplane wings, and because of that (and also a limitation from the speed of sound), they are limited in size, with the biggest helicopter being the soviet Mil Mi-26 with a rotor measuring 35m in diameter. Comparing this to the biggest airplane wings ever, the stratolaunch (+115m)
Now flapping wings will create an acceleration in both upward and downward direction. If you flap your arm at great speed you will feel the effort varying over time, and it's a big problem. First, the bending of the wing will be huge because of this acceleration. Take a ruler with a hole and make it turn around said hole, you will not have any problems. Now make it flap at high frequency, and you will see the ruler flexing in each direction. That's a very bad thing for structure, they don't like to have a varying constraint like that. If you bend too much the small plastic thing of your pen, it will eventualy break, via a process named fatigue. Now considering a wing flapping 5 times per second for 15 hours of flight, and you will have 270 000 cycles, reducing the resistance of the material by 50% at least. Now imagine over a lifetime, and you will need very strong and heavy wings.
Next is the controlability, each wings will need to turn around its own axis to be able to create lift like a bird do. So this axis will create a complex and heavy attachment, and another system that should wistand the constraints of this flight. In an helicopter it's already a nightmare, so i'm very affraid of that in a ornithopter.
Then on a more practical note, have four flapping wings next to each other will be a nightmare for aerodynamics studies, and will create something difficult to control in vertical take of and landing, compared to a balanced circular rotor. Same in high speed, having four wings potentially breaking the sound barrier is not something that we want to do.
Finally, the motorisation needed to move an entire wing will be huge (in a regular aircraft or helicopter, you need to consume motor power to overcome two things: rotor acceleration and drag. Acceleration is only needed at the begining and then it's only drag that needs to be balanced. On the other hand on an ornithopter, you will need to consume power each time you want to reverse the rotation of the wing. Just imagine an helicopter alterning the direction of rotation of its blade 5 time per seconds and you will see the difficulty of such things.
Sure ornithopter did exist, and are today studied for small drone application, but the French ornithopter flyed basically cause it's a regular aircraft with wings, but the wings flapped instead of staying still. So an inneficient use of energy that finally killed the project
And for the future project looking like a bird, it's not meant to flap wings. You can see the propeller to push the aircraft, and the feathers-like features are here to improve the air flow around wing tip, like today's winglet and sharklets on most civil airliners. There is no hinge at the wing root and this aircraft is to big to move their wings at great speed. Airbus's "AlbatrossONE" will not be able at all to take off vertically, it's not meant to and it's not possible at this scale with flapping wings
So why birds flap their wings ? Isn't nature the best at finding the most efficient solutions ? Well, it is, but to a certain extend: it is impossible for any animal to create propellers, cause it will require a hinge able to do multiple rotations without any problem, and it is not possible. So the birds came with another great solutions: making the wings able to propel the bird. But it came with its own cost, and most big birds don't like to flap too often their wings, and would rather glide and soar. They are also limited in size, with the biggest known flying bird being 70kg in weight (argentavis magnificent, an extinct bird) and the largest flying animal may have been a pterosaur 12m in width and 200kg in mass, the size of the smallest planes that you can find.
I think we should be thinking more along the lines of check valves for the up stroke and down stroke. Allow air to pass thru the wing on the up stroke but seal in the down. I thing it would be easy to protoype.
Stationary and Rotating airfoils make sense because they maintain a constant direction and a steady resistance. Flapping wings abruptly stop and change direction several times a second. I don’t think there are materials strong enough to withstand that force and the vibration has to be insane. Dragonflies and bees buzz when they fly, imagine the buzz when it weighs a ton or more.
With deformable wings, this design can not only overcome turbulence, but *exploit* it like an insect.
The French has a rich history of aero engineering. Not many people outside of history buffs and engineers know this.
A prototype called Riout 102T was built back around ww2 was built by the french

5:28 Foreshadowing!
Casually observing that bugs' wings flap therefor fly, will never lead to manned flight; one would be better suited to observing a rower to determine flight-mechanics of flapping-wings: pivots on a rigid-wing would only toss the center of gravity repeatedly body-slamming the fuselage on deck. Wings would snap unless they bowed on every stroke, flapping angles would have to be pitched rolled swung and reversed twice per stroke.
13:27 Surely it's the... OrNITHOPter Number One, not the No-one.
You say "orthinopter" a *lot*.
An interesting idea, certainly. I do wonder about vibration problems, as I cannot imagine it would be a smooth ride. Also, it seems to me that ANY mechanical problem with the wings would automatically lead to a crash. With a conventional aircraft, if the engine gives out, then gliding remains at least a theoretical possibility; and if it loses a chunk out of a wing, then maintaining control MIGHT be doable.

kinda funny how the destroyed prototypes wings formed a Swastika like shape, almost foreshadowing for them lol.
It's a cool-looking concept, but at least for civilian aviation a pure ornithopter wouldn't work out. Notwithstanding the materials problem, safety of the passengers needs to be one of the highest priorities. Riout's ornithopter in the windspeed tunnel highlighted the problem: if the wings get screwed up, ALL the lift goes with it, unless there's some type of vertical thrusters to fall back on. A plane can at least glide.
One could argue that a helicopter has the same problem, but all rotors have to do essentially is spin, not flap a large surface through the air. The wear and tear would be tremendous.
5:26 the shape. . .
In the nature the biggest flaing creature by rapidly flapping it's wings is Kolibry, other smaller ones are insects. So you there is no way to scale this principals on a scale. The Kolibry is the biggest it can get airborne.
1:35 and no --- there's no way a huge aircraft can fly like a small dragonfly --- air itself behaves different for larger objects and the most doubtful is the wing flapping frequency --- no way the wings would need to flap that frequent as even big birds don't do that
5:22 looks like that one was made by Vichy France from the likes of it.
The funny thing is that this plane was not that far-fetched as it seems today. After all it wasn't that far removed from a couple of guys in a bike shop throwing an weak engine on a pile of fabric, wood, and wire and that flew.
i feel like having a static wing flip up and down will not be efficient. either have the wing do some kind of fold on the way up to reduce resistance. or have it work like a bee wing that kinda "drills" upwords
The wear and tear would be insane, maintenance costs would be insane.
For an ornithopter to work, I believe that the solution is not to make the wings go up and down, but to make the wings make movement similar to scooping the air and push it down. Like mosquitos do!
Do whatever you want with that information.
"It was able to travel 100 mtrs."
At 101 metres, the wings fell off due to metal fatigue?
"Airbus is making ornithopters" - shows designs that are not ornithopters.
LOL. You uploaded this as I was watching a documentary about jodorowsky's Dune.
What an abomination that would have been. I had to stop watching when he said he was going to kill off Paul, lol.
If nature had managed to invent joints that could freely rotate, I imagine birds would have evolved propellers.
Hearing “Brought to you by War
Thunder” instead of Squarespace was like a slap in the face
Perhaps a more acceptable option is vibrating membranes.
Directed high-frequency vibrations create a zone of compacted air and this is a good idea for experiments with modern materials.
Its amazing how many wonderful machines could be built with Unobtainium!
Id be terrified to ride this constantly worrying about the wings
To be honest, I don't know how he did not see it being a dead on arrival concept. I'm no engineer, nor physicist, I'm, in fact, a lonely depressed nearly junkie and even I understand that with that size the scale of forces will put so much strain on the wings and hull that everything will break apart. And even if the materials were sturdy enough to withstand forces like that, the vibrations -- oh man, I can't even imagine those. I'm pretty sure pilots would suffer from internal organs damage pretty soon. Humans had been trying to lerarn to fly for millenia coming up with different concepts and there is a reson for planes and helicopters being in the form as we know it, it's like he tried to reinvent the wheel.

Ornthinopter ornithoptner lmao every time he says it wrong differently.
The way an ornithopter would need to worl its wings are more in a figure 8 motion like how dragonfly do it.
The wings would need to twist and flap since a dragonfly or bee fly by creating a low pressure area above the wing it couldn't flyy like a normal airplane. It generates lift in a completely different way.
It seems pretty clear to me, and I'm not even an engineer, that the stresses on the wings changing direction so quickly would very quickly break something. Fixed wing aircraft only have the drag on the wing going in the same direction, and rotary wings always rotate in the same direction, so they are not constantly moving in one direction, then the opposite direction, several times per second. For fun, take a tape measure out and move slowly. If you only move it slowly, it will remain rigid, but if you move it faster, it will bend.
The dragonfly is the closest analogy. The main problem is one of mass. The bigger the size the higher the involved masses become, in this case particularly because the length of a wing will speed up the tips very strongly even at low flapping frequencies. It’s a bit like the question why we do not have exoskeletons like insects. We would become incredibly heavy and breathing ducts in stead of lungs would be too inefficient. There simply is a scale limit for such solutions.
Dragonfly wings do not flap, they rotate forward and back in a mostly circular motion
I could see a drone doing this.
Since we have a dragonfly like helicopter, now make a helicopter that looks like a beetle!
How do you pronounce ornithopter wrong after Dune 1 and 2?
And he said that the titular planet in the story is called Dune. It is not.
This is not an Ornithopter! From Greek Ornith means 'bird'. An Ornithopter is a device that imitates the flight of a bird.
This device imitates the flight of an insect. Therefore it should be called Entomopter!
Wow that’s actually very true!
