INVENTION
HYDRAULIC JACK TO ALTER AIRPLANE WING'S CAMBER


The old dilemma of the camber of an airplane's wings, which should be thick for takeoff and climbing but thin for speed in flight, has challenged Jacque Fresco of Hollywood, Calif., for patent 2,410,056. His solution is a small hydraulic jack in the cavity of the wing, with ribs radiating from top and bottom to change the wing's shape as the jack is operated.
