Abstract

A compact diffuser for high- power gas turbines is constituted by an initial substantially axial diffusion stage 5 defined by two conical coaxial walls 6, 7 and followed by a double curved diffuser with three walls 8, 9, 10, of which the intermediate wall 9 is cantilever-supported by a set of aerodynamically profiled ribs 11 disposed with their generating lines substantially parallel to the axis of the turbine and situated nearly at the end of the double curved diffuser. The diffuser is connected to the turbine exhaust casing by an envelope internal to the exhaust casing and having its contours smoothly joined to the diffuser. <IMAGE>
