Spiral Spring Wings
4 wing suit made of springy adaptive foam to make human powered flapping flight possible
Human Powered Flapping Flight would be possible with a 4-
wing, one piece suit made of springy foam and shaped
adaptively so that
it serves the purpose of smooting the person into the air.
The design principle would be to simplify completely, so
instead of having a 2-part suit with skeleton
skin, the foam suit would use density fading to achive
springyness in one area and lightness in another. The
suit would extend the capability of each apendage or of the
a whole to use all of its energy evenly in supporting itself in
air. One way to do this would be to graduate the shape and
thickness of the wings so that they fade slowly into the air
have extreemly sharp but flexible edges. I think the wings
should also be curled up around each appendage so that
only unfurl when the flyer excecutes a crawl style stroke
vigorously enough with all limbs. (See bad drawings at link
below.) Besides the spiral shape of the wings, (see link two)
this idea is basically just a "simplify" idea for human
flapping flight. Every design I've ever seen involves working
parts that would not be efficient and would eventually wear
out anyway. The
answer seems to me to be to simplify the design as much as
possible so that the one piece suit serves only the purpose
smoothing the person into the air so that they can use their
energy efficiently. I'm pretty sure the answer is in the
and the adaptiveness (gradual as opposed to sharp change in
every quality) of the wing suit.

||"The only thing that is better than Home Depot for sparking ideas is a forest." -- well said.
||So it would wrap my arm when I needed low wind resistance, and unwrap to offer high resistance to push the air when I needed to "flap". Oh yeah. Really fine drawings! I love the superhero connotation. I think you are going to fit in fine here, JHC.
||kudos, very creative. but as far as a
vertical take of is concerned, look at a
bird that is capable of that feat, it's
analogous pectoral muscles are near
half the weight of its body....
||I thought this said "Spiral spring wigs." Good for bouncing off the walls...
||triplenine: Most of the power for vertical take off would
come from leg wings. Leg wings would be wrapped
around legs until take off and only unfurled by air
resistance as the flyer pistoned all limbs during take off.
Wrapping wings would allow for walking in furled mode
and also optimize
tension over the unfurled wing in flying mode. Recent
discoveries suggest that the first flyers may have been 4-
winged and used their leg wings for power during
undulating flight, and only lost the lower wings to be able
to compete as they started soaring.
||Then there is the issue of wanting to go to the toilet in a really big hurrrrrrryyyyyy.
