Method for starting a turbomachine

摘要

A method of starting a turbine engine, including a re-try performed if a main injector has not ignited when a shaft has reached a first predetermined speed value, the re-try including: a stopping during which a starter and the ignitor device are stopped; a second ignition during which fuel is injected into the combustion chamber, the ignitor device being actuated, the second ignition being performed when a speed of rotation of the shaft reaches a second predetermined speed value; and a second starting during which the starter is actuated once more to drive the shaft in rotation.

1. A method of starting a turbine engine, the turbine engine including: a combustion chamber including an ignitor device and at least one main injector, the combustion chamber including an outlet, a shaft connected to a compressor wheel arranged upstream from the combustion chamber to feed the combustion chamber with compressed air, and a starter connected to the shaft,
the method comprising: a first starting during which the starter is actuated to drive the shaft in rotation; a first igniting during which fuel is injected into the combustion chamber, the ignitor device being actuated; performing a re-try when the at least one main injector has not ignited when the shaft has reached a first predetermined speed value, performing the re-try comprising:
a stopping during which the starter and the ignitor device are stopped;a second igniting during which fuel is injected into the combustion chamber, the ignitor device being actuated, the second igniting being performed when a speed of rotation of the shaft reaches a second predetermined speed value; anda second starting during which the starter is actuated once more to drive the shaft in rotation.
