Abstract
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.
