Abstract

A hot fairing structure (102) for a pre-diffuser (100) includes a ring-strut-ring structure (118) that comprises a multiple of hollow struts (200), and a multiple of diffusion passage ducts (124) attached to the ring-strut-ring structure (118). A pre-diffuser (100) for a gas turbine engine (20) includes an exit guide vane ring (104) having a multiple of exit guide vanes (108) defined around an engine longitudinal axis (A), a ring-strut-ring structure (118) adjacent to the exit guide vane ring (104) to form a multiple of diffusion passages (120) defined around the engine longitudinal axis (A), an inlet to each of the multiple of diffusion passages (120) smaller than an exit from each of the multiple diffusion passages (120) through the ring-strut-ring structure (118), and a diffusion passage duct (124) attached to the ring-strut-ring structure (118) at the exit from each of the multiple diffusion passages (120).
