Abstract
A cover is provided to conceal the forward-facing step defined by the protrusion of the first stage diaphragm into the LP inlet. The cover presents a smoothly contoured surface to the flowing fluid in both radial and circumferential directions and thus reduces energy loss of the working fluid, thereby to increase performance of the LP turbine.
