Evolution has done a pretty good job of producing efficient wings in birds and insects. In particular, natural wings tend to be quite flexible and this allows animals to generate lift and thrust with ...

A team from MIT and NASA led by Neil Gershenfeld is developing a new type of "morphing" wing that rather than using conventional flaps, changes its shape. This new wing is made up of overlapping ...

Bat wings are like hands: meaty, bony and full of joints. A new study finds that bats take advantage of their flexibility by folding in their wings on the upstroke to save inertial energy. The ...

A team that has created a supersonic jet design resembling a flying shuriken has been awarded a US$100, 000 grant from NASA’s Innovative Advanced Concepts (NIAC) program to continue development of the ...

For an airplane to get airborne or climb in flight, the overall downward force of air on its wing surfaces must be less than the upward force. In this interactive activity learn how wing shape, angle ...

(Phys.org) -- Bat wings are like hands: meaty, bony and full of joints. A new Brown University study finds that bats take advantage of their flexibility by folding in their wings on the upstroke to ...
