Impingement baffle with embedded deflector

摘要

An impingement baffle (62) includes a perforate plate (64) having a pattern of impingement holes (66). An imperforate deflector (68) is spaced from the plate (64) and is smaller than the plate for deflecting inlet air around the deflector to the holes (66). The baffle (62) is disposed between a turbine shroud and supporting hanger, and the deflector (68) is disposed between the hanger and the baffle (62).
