ABSTRACT:
A supersonic jet engine installation for improved noise abatement and thrust augmentation. There is an intake section, an engine, a mixing section, an exhaust section, and a secondary air passageway. Ambient air is directed into the engine and also into the secondary air passageway. The exhaust from the engine and the flow from the secondary air passageway are directed into primary and secondary passageway segments to mix and then be discharged from the engine as a supersonic mixed flow. In the noise suppressing mode, it is desirable that the mixed flow be subsonic.
