METHOD FOR MANAGING A TURBOMACHINE STARTER VALVE FAILURE

摘要

The present invention concerns a method (200) for managing a breakdown of a starter valve of a starting circuit of an aircraft turbine engine, comprising the following steps: —starting (203) the turbine engine, a state-change command being sent to the starter valve in order for it to open;—increasing (204) the engine speed of the turbine engine to a predefined first threshold,—during said increase (204) in engine speed,—if a difference in position has been detected (201) between the position sensors before the step of starting the turbine engine or if a difference in position is detected (205) between said position sensors, determining (207) the position sensor that has switched between the closed position and the open position, the other position sensor having remained in the open or closed position;—when the first threshold is reached, storing (209) the position sensor that has switched between the closed position and the open position as healthy and the position sensor that has remained in the open or closed position as faulty, so as to measure the state of the starter valve only on the basis of the position of the healthy position sensor.
