초록

A structural frame assembly for use in a gas turbine engine includes an annular inner hub, an annular outer casing and a plurality of circumferentially-spaced and radially extending hollow struts connected to the inner hub and outer casing. Hot gases are extracted from the engine primary flowpath, using a scoop attached to each strut, and are directed through the struts to the inner hub interior for the purpose of reducing a bulk temperature differential between the outer casing and the inner hub and for providing a uniform temperature distribution withi...
