Maybe I'm spoiled by the fact of playing with lots of working toy ornithopters as a kid. Plus I remember Snowbird, so my assumption has been that its probably possible but not really practical.

That ornithopter isn't how the Dune Ornithopter functions though. The Dune Ornithopter doesn't have flexible wings, they don't flap, they merely vibrate. Every action has an equal and opposite reaction, so my contention is that even with super advanced technology to vibrate at super high frequency, it still couldn't fly because there would be no positive lift.
January 28, 20224 yr If that's the explanation then no, probably it wouldn't work. My impression was not that they were vibrating. I thought that they were flapping at such a high rate of speed that they appeared to blur. (Hummingbird wings, or like a Dragonfly) Edited January 28, 20224 yr by HiFlyer We are all connected.....

The Comanche was quite a machine, very manoeuvrable and with an accompanying engine sound that was almost a scream. Weird! Edited January 28, 20224 yr by martin-w

They would also have to change angle on the upward strike I reckon. Edited January 28, 20224 yr by martin-w
January 28, 20224 yr The Air Force had something smiliar in the old days as I recall. The Kaman HH-43 Husky Noel The tires are worn. The shocks are shot. The steering is wobbly. But the engine still runs fine.

Its not a new concept. The pusher at the back is though and was based on the Bell X2 concept. Then we have the Airbus X3 which I love.

But the Kaman had twin rotors next to each other but slightly tilted so the rotors interwove with each other when they were spinning. The ones I saw at US Air Bases had foam fire suppression equipment hung below them to put out crash fires from above. Have there been any other helicopters that had interwoven rotors??
