摘要

A regulator device (10) for reducing the risk of surging in a turbine engine (3) that includes a gas generator (4), an air extractor (8), and a mechanical power take-off device (100). An engine computer (11) includes storage (16) 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 (10) including a first measurement device (20) for measuring current air extraction, and a second measurement device (30) for measuring current mechanical power take-off, with the engine computer (11) controlling acceleration of the turbine engine (3) by implementing the acceleration regulation relationship corresponding to the current air extraction and to the current mechanical power take-off.

1. A method of reducing the risk of a surge phenomenon appearing in a turbine engine, the turbine engine including a gas generator, air extractor communicating with the gas generator and capable of extracting air from the gas generator, and mechanical power take-off means that co-operate mechanically with the gas generator, wherein:
a plurality of acceleration regulation relationships are established before the turbine engine is used and are stored in an engine computer by the manufacturer, each acceleration regulation relationship corresponding to air extraction performed by the air extractor in an air extraction range, and to mechanical power take-off performed by the mechanical power take-off means in a mechanical power take-off range; while the turbine engine is being used, current air extraction and current mechanical power take-off is measured continuously; and acceleration of the turbine engine is controlled by implementing the acceleration regulation relationship corresponding to the current air extraction and to the current mechanical power take-off.
