AIR INTAKE PLENUM WITH STRUTS

DRIVE March 18, 2026

An air intake plenum (22) for a gas turbine engine (20) is provided that includes an axial centerline (30), first and second gas path surfaces (58, 60), and a plurality of struts (42). The gas path surfaces (58, 60) are spaced apart from one another and define at least a portion of a plenum interior (61). The struts extend lengthwise between the gas path surfaces (58, 60). Each strut has a cross-section geometry. The cross-section geometry has a center, and major and minor axes (50, 55). The struts are circumferentially spaced apart from one another within the plenum (22). Each strut is oriented at a clocking angle theta. The clocking angle theta for each respective strut is disposed between the major axis (50) of that strut and a line (62) that intersects the cross-section geometry center of that strut and the axial centerline (30). At least one strut of the plurality of struts (42) is oriented at a clocking angle theta that is greater than zero.
