Gas turbine engine diffuser

Patent ·
OSTI ID:7349972
Apparatus for diffusing the working medium gases which flow from the compression section of a gas turbine engine is disclosed. A controlled diffuser comprising an inner and an outer flow path shroud initially increases the static pressure and decreases the velocity of the medium gases. The diffusion process is completed downstream of the flow path shrouds in a dump region of rapidly increasing flow area. The inner and outer shrouds of the control diffuser are concentrically supported at both the upstream and downstream ends. The inner and outer shrouds support the compressor exit vanes within the path of working medium gases flowing from the compressor and damp vane vibration during operation of the engine.
