摘要
Comparatively cool fan bypass air in the annular space surrounding the air compressor of a fan jet engine is diverted near the front of the engine into a duct leading to right and left hand aircraft wing leading edge ducts which in turn deliver the bypass air to a wing blowing device to augment wing lift. All of the fan-generated bypass air can be positively forced into the common duct or manifold by operation of a guided flexible metal strip of sufficient length to form a concave helical diverter vane extending for one complete turn in the annular bypass air engine space when activated by a power control mechanism. Fixed coacting guides shape the normally flat metal strip into the proper cross sectional configuration when the strip is driven to its active bypass air diverting position.
