A regulator device () for regulating a turbine engine (). The regulator device () includes mechanical power take-off means () for taking off power mechanically from a gas generator (), and an engine computer () controlling said engine () to comply with at least a first limitation (LimTET, LimT45) of a temperature (TET, T45) of the gas within the engine, and with a second limitation (LimNg) of a speed of rotation (Ng) of the gas generator (). The engine computer () determines whether the speed of rotation (Ng) of the gas generator has reached said second limitation (LimNg), and whether said temperature (TET, T45) has reached said first limitation (LimTET, LimT45). An avionics computer () causes the mechanical power take-off means () to operate if the speed of rotation (Ng) of the gas generator () has reached said second limitation (LimNg), and if said temperature (TET, T45) has not reached said first limitation (LimTET, LimT45).

Device and a method of regulating a power plant including at least one turbine engine, and an aircraft

A regulator device () for reducing the risk of surging in a turbine engine () that includes a gas generator (), an air extractor (), and a mechanical power take-off device (). An engine computer () includes storage () that stores a plurality of acceleration regulation relationships, each acceleration regulation relationship corresponding to air extraction in a first range, and to mechanical power take-off in a second range. The regulator device () including a first measurement device () for measuring current air extraction, and a second measurement device () for measuring current mechanical power take-off, with the engine computer () controlling acceleration of the turbine engine () by implementing the acceleration regulation relationship corresponding to the current air extraction and to the current mechanical power take-off.
