Abstract: A system includes a turbine casing assembly that includes an outer shell and an inner shell positioned substantially concentrically within the outer shell. The inner shell includes an inner surface facing away from the outer shell and an outer surface facing toward the outer shell, and the outer surface has one or more false flanges. At least one of the one or more false flanges includes a first surface protruding from the outer surface and facing the outer shell, and a flow diverting portion extending between the first surface and the outer surface of the inner shell. The flow diverting portion includes a first portion that diverges in a first circumferential direction between the first surface and the outer surface.

Abstract: A distortion control ring disposed and connected between a fuel injector body and a clamping device. The distortion control ring is utilized as an intermediary for transmitting a static clamping load from the clamping device to the fuel injector body. The distortion control ring includes a cylindrical shaped main body having a bore extending therethrough between an upper surface and a lower surface. The upper surface of the main body being adapted for mounting a return spring thereon. The lower surface having an annular portion for contacting the fuel injector body. A radial flange is formed on the distortion control ring adjacent to the main body for contacting the clamping device and receiving the static clamping load. The clamping device engages the radial flange at a distance radially outward of where the lower surface of the main body contacts the fuel injector body.
