A double bypass, variable cycle gas turbofan engine is provided with a variable area bypass injector which varies the area through which the inner bypass stream is injected into the outer bypass stream. The bypass injector comprises an upstream variable area, double bypass selector valve, the position of which determines whether the engine will operate in the single or double bypass mode, and a downstream static pressure valve which defines an optimum flow path for injecting the inner bypass stream into the outer bypass stream. The ability to vary the ar...
An improved gas turbofan engine of the type having a core engine, a front fan section for pressurizing a flow of air, an outer bypass duct for bypassing a stream of pressurized air around the core engine, an aft fan section for further pressurizing the air discharged from the front fan section and an inner bypass duct for bypassing an airstream from the aft fan section into the outer bypass duct and around the core engine, wherein the improvement comprises: a common bypass duct for receiving confluent streams from the inner and outer bypass ducts and byp...
