Abstract
A method facilitates assembling a gas turbine engine assembly. The method comprises providing at least one propelling gas turbine engine that includes a core engine including at least one turbine. The method also comprises coupling an auxiliary engine to the propelling gas turbine engine such that during operation of the propelling gas turbine engine, at least a portion of the airflow entering the propelling gas turbine engine is extracted from the propelling gas turbine engine upstream from the core engine turbine, and channeled to the auxiliary engine for generating power.
Claims39
A method for assembling a gas turbine engine assembly, said method comprising:
- providing at least one propelling gas turbine engine that includes a core engine including at least one turbine;
- and
- coupling an auxiliary engine to the propelling gas turbine engine such that during operation of the propelling gas turbine engine, at least a portion of the airflow entering the propelling gas turbine engine is extracted from the propelling gas turbine engine upstream from the core engine turbine, and channeled to the auxiliary engine for generating power.
A gas turbine engine assembly comprising:
- at least one propelling gas turbine engine comprising a fan and a core engine downstream from the fan;
- and
- an auxiliary engine used for generating power, said auxiliary engine comprising at least one turbine and an inlet, said inlet coupled in flow communication with said propelling gas turbine engine core engine, such that a portion of airflow entering said at least one propelling engine is extracted for use by said auxiliary engine.
A gas turbine engine assembly in accordance with claim 23 wherein said control system comprises at least one adjustable air throttle valve coupled in flow communication with said auxiliary engine.
An aircraft gas turbine engine assembly, said assembly comprising:
- at least one propelling gas turbine engine comprising a core engine and an exhaust, said core engine comprising at least one turbine, said at least one propelling gas turbine engine for generating thrust for the aircraft;
- and
- at least one auxiliary engine comprising an inlet, at least one turbine, and an exhaust, said inlet coupled in flow communication with said at least one propelling gas turbine engine, such that a portion of airflow flowing through said propelling engine is extracted from said propelling engine upstream from said propelling engine turbine, and is channeled to said auxiliary engine for generating power.
