초록

The fan section of a gas turbine engine is divided into a front section and an aft section axially displaced downstream of the front fan section. A duct is provided for bypassing the inlet gas stream around a gas generator. The bypass duct has a first inlet disposed intermediate the front and aft fan sections and a second inlet disposed downstream of the aft fan section. In order to provide increased flexibility in modulating the engine bypass ratio, a diverter valve is provided downstream of the aft fan section to selectively distribute the airflow exha...
