I've been designing an ornithopter, or bird-machine, if you will, but this is intended to be a manned aerial vehicle.. No, actually- it's like a jetpack, but with lightweight wings using carbon fiber and an electric engine with lithium batteries. The question here is- what is the ideal method of ornithopter flight? And why, of course. So far, my design is radically different- for liftoff, that is. The actual flight is done exactly like a bird's, but liftoff is done differently, by sheer brute force directly downward flapping using specially-designed wings to maximize vertical thrust, which is used in place of traditional "lift". This may seem impossible to maintain balance within reasonable terms, but it has a special balancing system that doesn't require computer processing, rather it works entirely mechanically(don't ask) to alter the wing thrust vector in real-time, and does automatically, as no human could ever hope to do this themselves, obviously. But don't worry about this aspect of the design, for now I want to focus entirely on vertical takeoff idealization. I'd like to get into a big discussion over this. I've been doing lots of research, and I can't stop coming to the conclusion that my current method of liftoff is actually the best one by far, but that just sounds like complete nonsense when I think of it like that, so it makes me uneasy and wondering what I'm missing that makes the reality of it the complete opposite, probably..
