=this young engeneers from prof.Kiselov scuul are continued workornithoptor guys credit for not making bird looking wings and using basic rectangular ones.
in 1977 dr Jerzy Wolf was experimentally realised His methodeI tried pump climbing Rogallo wing hang gliders
I removed credit for that. The wings are made like model airplane wings, instead of ornithopter wings. It has independent parts pivoting on a rigid spar for twist rather than flexing for twist. This basically eliminates the span-wise wing bending modes of the wing. That leaves a lot of potential ornithopter efficiency out of reach for this design. That may be why it needs 8 wings to fly instead of 2, or even 4 like the dragonfly.I'll give the OP ornithoptor guys credit for not making bird looking wings and using basic rectangular ones.
Far too many have copied the appearance of bird's wings but not the functionality trying to fly. The Wright Flyer didn't have tip feathers unlike several failed previous designs. Seeing beyond the pretty to the function is a talent.
flapping wing generate some vortices with huge energy...basic principles of flapping wings that, if they had known, would have taken them down a very different design path.
My Russian is not too good, so I have no idea what he said.Has anyone posted this yet?
I can just imagine Jonathan Winters telling that story.My Russian is not too good, so I have no idea what he said.
But I do recall my old friend Maude Frickert recounting the story of her brother Maynard, who had scotch taped 146 pigeons to his arms... he was airborne for a good twenty seconds, she said, until somebody threw a bag of popcorn in the stone quarry.
