Hook, Jr, R B; Montanye, R D

This patent describes an improved gas turbine engine of the type comprising an outer casing, axially spaced apart turbine wheels rotatably mounted within the casing and having radially outwardly extending blades mounted thereon. A stationary annular member includes air foil vanes positioned between each of the turbine wheels. The bladed turbine wheels and the stationary annular members define a hot gas path. An annular plenum is defined between the hot gas path and an outer wall of the stationary member and a diaphragm is depending from an inner wall of the stationary member. Air passageways through at least some of the air foil vanes for conducting cooling air from the annular plenum to the diaphragm.
