AID SYSTEM FOR RE-STARTING ENGINES AFTER TOTAL LOSS OF MOTORIZATION

摘要

P System for restarting assistance for at least one engine (1) of an airplane in flight, in the event of total loss of engine. The aircraft comprises a hydraulic circuit (5) for the servo-controls (6), normally supplied by a main pump (4) driven by the engine (1), and a backup pump (16) driven by an air turbine. (19) under dynamic pressure which is deployed from the fuselage in the event of loss of aircraft engine power. The excess hydraulic energy from the emergency pump (16) is used to drive the main pump (4), which will be of a reversible type and will operate as a motor, in order to increase the speed of autorotation of the motor off (1). and facilitate the re-ignition of the latter, even at low speed of the aircraft. /P
