TURBOJET-ENGINE THRUST-REVERSAL UNIT WITH DOORS FORMING BUCKETS COUPLED WITH MOVABLE DEFLECTOR Russian patent published in 2001 - IPC

FIELD: aircraft engine manufacture. SUBSTANCE: thrust-reversal unit of double-circuit turbojet engine has hollow swivel doors 3 integrated into external fairing of engine nacelle during forward thrusts and opposing deflection of gas flow during thrust reversal when they form buckets. Movable deflector 24 is coupled with each swivel door 3. Opening of swivel door 3 positions movable deflector 24 above outer surface of external panel 4 of door 3 so that interaction between gas flow ejected from inner space of swivel door 3 and gas flow deflected by outer surface of mentioned door 3 is made impossible. EFFECT: improved aerodynamic characteristics of swivel doors. 14 cl, 12 dwg
