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.

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.

I always find the way you said "Orthinopter" rather than "Ornithopter" is hilarious :D

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.

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.

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. 💥💥💥💥💥

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.

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.

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.

2:16 CH53 "Yas'ur" יסעור in the wild. We fly them is very dusty environmets, notice the specially ordered particle filters on the engine intakes.

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.

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.

"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.

I'm in toronto right now, and It's pretty rare for a project like THIS to happen near me.

im from Germany and i can really tell how you struggled with "Messerschmitt" you said it like Mesch scher schmitt :D Love your videos

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 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

Its amazing how many wonderful machines could be built with Unobtainium!

Isn't this the "flying plane" that NerdCubed showed off in one of his flight simulator videos a while ago?

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.

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.

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...

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.

kinda funny how the destroyed prototypes wings formed a Swastika like shape, almost foreshadowing for them lol.

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.

Whereas fixed wings need not deal with reciprocating movements. And they can still fail often enough. Look at the difficulties encountered in the cancelled Boeing SST project. The design called for a swing-wing and the problem came with the pivot point getting exponentially heavier with the size of the aircraft. Even the early F111 had issues and this was just with movement in one axis. It’s the same effect that limits the size of insect exoskeletons.

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. Just imagine! - tens of thousands of small ramjet engines assembled in panels and launching plasma synchronously at a huge frequency (hundreds of kilohertz). Plasma jets form toroidal air vortices - this air cushion creates lift and acceleration.💥 🕳💥💥💥💥💥💥 💫 💫 💫 💫

Always heard wings stall from the wing root ans progresses out to the tip I may be in error, but that's what I remember

Only if they are designed this way on purpose to prevent more catastrophic tip stalls. It’s called washout.

what is the glide rate and can it auto rotate (or something similar)?

13:43 if that's how a real life Ornithopter really flies, my god the motion sickness 😂🤮

Someone did the math and the wings of the ornithopters from the Dune movie would be breaking the sound barrier. So each wing would be creating 2 sonic booms in one full cycle and there are at least for wings so that would be one LOUD craft. With all the other problems like material strength and the articulation required it seems so much easier to just use helicopter blades.

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

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

Wear and tear and maintenance even on a modern version will likely be significant A prop or fan turning on a fixed point in 1 direction is way more simple and far less prone to wear and breakages, This going up and down at high speed constantly changing direction is going to be suicidal in anything less that countries or companies with large maintenance budgets and facilities.

Im not surprised this wasnt able to be made The most realistic part about dune is spice letting you see the future and that really says something

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.

Should have wheels on wingtips for angled landings

5:22 looks like that one was made by Vichy France from the likes of it.
