Abstract
Device and process for regulating the power of the engines of a rotary wing multi-engine aircraft.The regulating device (1) comprises, in addition to main regulating systems (2, 6) associated with the engines (M1, M2) of the aircraft, auxiliary regulating systems (12, 13) associated with said engines (M1, M2) and means (10, 11) for determining the speeds of rotation of the engines (M1, M2). Each auxiliary regulating system (12, 13) is capable of automatically adjusting the flow rate of fuel in such a way as to slave the speed of rotation of the associated engine, when its main regulating system has failed, to the speed of rotation of the other engine of the aircraft.
