U.S. Patent Specifications

Abstract

In a gas motivated power plant, substantially cylindrical outer wall structure, inner fairing structure having a rearwardly converging exterior surface and coaxially disposed within said wall structure to provide a rearwardly diverging annular diffuser passage adapted to conduct a high velocity stream of gas under pressure, said fairing structure having formed therein an interior chamber and a plurality of bleed ports providing communication thereto from a downstream region of said diffuser passage having relatively large flow area, a plurality of radially disposed supporting struts secured to said wall structure and to said fairing structure at points upstream of said bleed ports therein, at least one of said struts having an interior passage communicating with said chamber in said fairing structure, and a plurality of discharge ports formed in each of said struts, said discharge ports being remote from said bleed ports and communicating with said diffuser passage in an upstream region of relatively small flow area, the differential between static pressures of gas in the respective downstream and upstream regions of the diffuser passage serving to effect withdrawal of boundary layer gas away from the exterior surface of said fairing structure through said bleed ports, and return of such gas to the main gas stream by way of said discharge ports.
