AIRCRAFT AIR GUIDE PRESSURE CONTROLLED FLAP, METHOD OF FLAP POSITION ADJUSTMENT AND FORCED AIR COOLING SYSTEM INCORPORATING SAID FLAP Russian patent published in 2009 - IPC B64D33/02 B64D13/04 

FIELD: aircraft engineering.

SUBSTANCE: proposed air guide flap features one its surface facing air duct and subjected to aid duct air pressure and its another surface is subjected to pressure of relative flow that flows around aircraft. Air guide flap incorporates actuator to automatically open and close it that interacts with adjuster controlling flap position. To maintain stress in air guide flap at low level, there is a device to determine force that defines that applied to actuator from the difference between pressure prevailing in air duct and that of relative flow that flows around aircraft. Aforesaid adjuster control air guide flap position so as to force applied to actuator at any moment is, in fact, zero.

EFFECT: expanded performances.
