WINGS
Abstract
Presented is a general account of aircraft wings from the envisioned, retractable folding wings for hypersonic aircraft to the flopping-wing aircraft resembling birds in flight. Evolution to wings from triplanes to the swept-back types of today is pointed out, as well as developments in various types of foreign VTO aircraft. Mention is also made of foreign experiments in pulling wings and jet wings. The pulling wing consists of small jet engines built into the wing along the wing span to fuse the engine and wings of the aircraft. The jet wing has a narrow slot in the trailing edge through which a stream of escaping engine gases are released at high speed to give greater lift and to lower the probability of flow collapse. For pylon-mounted engines the gas stream is directed toward the flaps to achieve this same effect.
