    I invented a prototype of a flying machine with flapping wing. I named this invention as "hansdacraft". This invention is basically about a simple flapping mechanism. A suitable wing can be connected to this flapping mechanism to generate thrust or lift through flapping.



    Is there any laboratory facility, where this prototype can be developed further?

    Hahahahaha. Uh no.

    This is just a wild ass guess, but you're not an Aeronautical Engineer are you? Do you have an idea about wing design or, oh hell, never mind; let's just leave it at ...no, nobody with a facitlity will want to test this further.

    I did not design any wing. I only developed a flapping mechanism.

    No, you didn't. A "prototype" of a flying machine with flapping wings is a working model of a flying machine with flapping wings. What you have invented is the flapping mechanism.

    BTW, the technical term for an aircraft that flies by flapping its wings like a bird is an ornithopter.

    BTW Hansda . . . lots of jealous 'scientists' on the forum who will denigrate anyone-else's ideas!! Keep up the interesting and creative work!! wlminex

    Nothing to do with jealousy. Just observing that it is nothing new. Several types of ornichopters can be bought as toys, these days.

    In the developement history of flight, ornichopters represent a dead-end, because the materials and engined available at the time did not suffice to build working examples. Now we can, but the principle has no practical use exept where it is desirable to impersonate birds or insects (and as novelties), because they are less efficient on all counts than fixed-wing planes and they lack the ability to hover, like helicopters.

    I think alongwith the design of wings, flapping mechanism is also important for success of these kind of flying machines.

    Not necessarily a dead-end for very small flying devices.

    Hansda should be aware that nothing (as in living organisms) heavier than a human has ever really been able to fly properly in recorded history or prehistory without updrafts or wind velocity gradients to borrow energy from. Non-fixed wings are wasteful at such a size.

    I think paragliders can support a human being for some considerable amount of time in the air.

    Did you read what I wrote?

    FTL said "flying." That's not flying. Paragliding borrows energy from updrafts and/or wind velocity gradients. A reasonable definition of "flight" in the context of aeronautics is: starting at or near ground level, the ability to increase and maintain altitude while moving in a chosen direction, without the aid of energy transfers from the atmosphere.

    In other words, being able to get off the ground and travel in a direction of your own choosing, in completely calm air.

    Not only that they don't fly; I can't understand why he's referencing paragliders at all, which do not use flapping wings to do anything (they kind of bend a single wing to steer; but that's not substantially different from any rigid winged aircraft which use flaps on the wings to change their shapes to control flight).

    The only thing I could make of the reply was that he either didn't read my post at all, or he has no idea what he's talking about. I'll be charitable and assume the former

    If a suitable flapping mechanism can be connected to a paraglider, then through flapping the paraglider can generate lift and gain height.

    hansda, list the detailed schematics of this flapping wing mechanism here, or just message me.

    No, it can't; it's been tried. You need a lot more than "flapping" to achieve powered flight.

    You can achieve sustained, powered flight, using flapping wings. It is just not very effective.

    Yes, that's been accomplished with a rigid wing. It has never been accomplished with a paraglider, despite several attempts.

    he took to the sky with his arms spread to conquer.

    This is a flapping mechanism for flying, powered by a man.
