FIELD: engines and pumps.
SUBSTANCE: proposed device comprises sealed rotary reversing grids and flaps. Said sealed rotary reversing grids and flaps are arranged in fixed case to displace between fixed positions corresponding to thrust reversal open and closed positions. Flaps cover outer vent duct and are connected by leverage with said sealed rotary reversing grids via hydraulic cylinder driven via engines central control board. Besides, the device comprises the unit for reversal neutraliser control to display the position of rotary reversing grids in the entire operating range. Thrust neutralisation control toggle switch is arranged at the unit input to interact via engine central control board. Unit output is connected with hydraulic cylinder electric mechanisms and valves. Additionally, this device incorporates mechanical dogs hinged at rotary reversing grids.
EFFECT: expanded operating performances in rescue operations, higher reliability and efficiency, improved takeoff and landing characteristics.
