METHOD FOR MANAGING A TURBOMACHINE STARTER VALVE FAILURE

摘要

The present invention relates to a method (200) for managing a failure of a starter valve of a starting circuit of an aircraft turbomachine, comprising the following steps of: - starting (203) of the turbomachine, a change of state command being sent to the starter valve to open it; - increasing (204) the engine speed of the turbomachine to a first predetermined threshold, - during said increase (204) of the engine speed, - if a positional difference has been detected (201) between the position sensors before the step of starting the turbomachine or if a positional difference is detected (205) between said position sensors, determining (207) of the position sensor having switched between the closed position and the open position, the other position sensor having remained in open or closed position; - when the first threshold is reached, storing (209) the position sensor having switched between the closed position and the open position as healthy and the position sensor remained in the open or closed position as defective, so as not to measure the state of the starter valve only on the basis of the position of the sound position sensor.
