Method and system for regulating power in the event of at least one aircraft engine failure

Abstract

A method to optimize resources needed to continue flight if at least one main engine is lost, by relieving a propulsion system that has remained operative of all or some of non-propulsive energy demands, by additional generation of non-propulsive power, operating continuously. The method uses a GPP unit that operates constantly in flight while taking up some of nominal total non-propulsive power of the aircraft, to supply increased non-propulsive power almost instantaneously, based on at least three respective emergency regimes at a time of engine failure. A control and monitoring function of the GPP calculates elapsed time for each emergency regime, and informs a data processing unit thereof, while emitting an alarm if operating periods allocated to each emergency regime are exceeded, and the emergency function adjusts non-propulsive power demands made by the aircraft between main engines and the unit GPP either automatically or on orders of a pilot.
