Abstract:
1. 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; 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 and channeled to the auxiliary engine for generating electrical power; and coupling a modulating valve in flow communication to the propelling gas turbine engine to control the flow of airflow from the propelling gas turbine engine to the auxiliary engine, wherein the modulating valve is selectively operable to control extraction and mixing of airflow from the propelling gas turbine engine from at least two of a plurality of extractions points.
