Abstract
A turbine engine having an engine core having a compression section, combustion section, a turbine section, and an engine drive shaft. The turbine engine includes an air turbine starter having a housing defining an air flow passage. The air turbine starter can operate in a start-up mode and a shut-down mode. The turbine engine further includes a gearbox and a drive unit.
Claims20
A method of operating a turbine engine comprising:
- in a start-up mode, flowing a pressurized air in a first direction through an air flow passage of an air turbine starter to rotate a turbine of the air turbine starter, which is operably coupled to an engine drive shaft of the turbine engine, to affect a rotation of the engine drive shaft by rotating the turbine about an axis of rotation;
- and
- in a shut-down mode, rotatably driving the turbine of the air turbine starter to generate a pressurized air flow flowing in a second direction, opposite the first direction, through the air flow passage of the air turbine starter.
