INSTALLATION FOR AERODYNAMIC BLOWING OF AIRCRAFT ENGINE Russian patent published in 1999 - IPC

FIELD: aerodynamic blowing of aircraft engine. SUBSTANCE: installation uses a stationary force-measuring tool for engine to be blown and an auxiliary turboprop engine for blowing in a rigid tool capable of its moving in horizontal plane around the engine under test and fixing in the course of blowing in the required angular position. It comprises a curvilinear rail track intended for movement of the auxiliary engine on it. The tool of the auxiliary engine is furnished with running wheels and fixing jack supports. Installed under the air intake of the engine under test on a rail track is a runway simulator in the form of a flat movable table with rounded off, for instance to lemniscate, peripheral and front edges. EFFECT: provision during tests of blowing conditions corresponding to operating conditions on aircraft at take-off or landing at accurate measurement of thrust of engine of any power. 3 cl, 4 dwg
