Pretty impressive...Of course not very practical...however, can somebody answer me this question.
As thrust is used to push air under and against the area of a wing or rota blade to generate lift. And the greater the thrust the greater the
lift...but also as seen in the video... with a lot lower thrust you can still achieve lift as long as you have a much larger area of wing or rota. In
other words its an equation that states more thrust plus less area and less thrust plus more area.
The obvious problem using less thrust..like human power...is that you have an impractically large and flimsy vehicle. So as the equation states that
wing area is the real issue..then why not have a stack of rotas,
If you could make a stack of rotas, but building them with a very small space between each one, it should equate to much greater area, but used over a
much smaller diameter making the machine much smaller and more practical.
Has anyone considered this? I have seen early helicopter designs using stacked rota blades...but what Im suggesting is using carbon fiber..or
something similarly strong and light weight.. to make much lighter stacks, with many more blades in them...so perhaps 10 blades but stacked in a meter
Would this work?
