A circular thrust augmenting ejector has an annular wall which defines a central passageway and a convergent contoured inlet section, a constant area cylindrical mixing section and a divergent conical diffuser outlet section. The inlet, mixing and outlet sections merge one into the next in axisymmetric serial relationship. The ejector also has a plurality of discrete primary nozzles arranged about the periphery of the annular wall at the entrance to the inlet section thereof for injecting a primary flow of high velocity air into the inlet section and thereby entraining a secondary flow of ambient air into the central passageway of the ejector.

A circular thrust augmenting ejector, comprising: (a) a contoured inlet section having a surface; (b) a constant area mixing section; (c) a conical diffuser outlet section; (d) said inlet, mixing and outlet sections merging one into the next in serial relationship, having a common central axis, and defining a central passageway; and (e) a plurality of discrete primary nozzles positioned at the entrance but spaced from the surface of said contoured inlet section for injecting a primary flow of high velocity air into said inlet section with a trajectory generally parallel thereto and thereby entraining a secondary flow of ambient air into said central passageway of said ejector.
