THRUST REVERSAL UNIT FOR TURBOJET ENGINE WITH ROTATABLE DOORS COUPLED WITH SYNCHRONIZATION AND CONTROL DEVICE Russian patent published in 2000 - IPC

Abstract RU 2151316 C1

FIELD: aircraft industry. SUBSTANCE: proposed invention is designed for double-flow turbojet engines. According to invention, thrust reversal unit has rotatable doors 7a, 7b integrated with outer wall of gas flow channel from fan at forward thrust and forming obstacles for deflecting gas flow, thus providing reversal of thrust. At least two power drives 23 to control movement of rotatable doors 7a, 7 b are coupled with one synchronization device 19 formed by electric motor 20, its electronic power system 21 and angled gearbox 22 coupled, respectively, with each power drive 23 through transmission coupling 26. EFFECT: provision of safe and reliable operation of thrust reversal unit if one of rotatable door fails to get locked. 9 cl, 6 dwg
