The Secret of Flight - Season 1 Episode 12 Эпизод 12
"Man seems to have surpassed nature as he can fly faster and higher than the natural flying creatures. But further study of the flying habits of birds and insects is still necessary." Dr. Lippisch presents a discussion on the wing motion of birds and insects and how the texture and shape of the wings differ with the various birds and insects. Not only airborne animals apply the laws of fluid motion; the program also presents the propulsive systems of fish and shows the action of the fishtail-propeller in the Smoke Tunnel.
