Abstract
An air turbine starter for starting an engine, comprising a housing defining an inlet, an outlet, and a flow path extending between the inlet and the outlet for communicating a flow of gas there through. A turbine member is journaled within the housing and disposed within the flow path for rotatably extracting mechanical power from the flow of gas. A secondary supply port is fluidly coupled to the flow of the pressurized gas in the housing.
Claims20
An air turbine starter, comprising:
- a housing defining an inlet configured to receive pressurized gas, an outlet, and a flow path extending between the inlet and the outlet for communicating a flow of the pressurized gas there through;
- and
- a secondary supply port fluidly coupled to the flow of the pressurized gas in the housing and adapted to provide a secondary supply of the pressurized gas from the housing.
An air turbine starter assembly, comprising:
- an air turbine starter including a housing having an inlet operably coupled to a flow of pressurized gas, at least one outlet, and a flow path extending between the inlet and the at least one outlet for communicating a flow of the pressurized gas there through, at least one turbine member journaled within a turbine section of the housing and disposed within the flow for rotatably extracting mechanical power from the flow of gas, a drive shaft operably coupled to the at least one turbine member and driven thereby;
- and
- a secondary supply port fluidly coupled to the flow of the pressurized gas and adapted to provide a secondary supply of the pressurized gas there through.
A method of operating an air turbine starter, the method comprising:
- providing pressurized air to an air turbine starter that includes at least one turbine member journaled within a portion of the air turbine starter;
- extracting mechanical power from the pressurized air via the at least one turbine member;
- and
- selectively utilizing the provided pressurized air, from the air turbine starter, in a secondary application unrelated to the extracting mechanical power via the at least one turbine member.
