Investigation of the Pressure-Loss Characteristics of a Turbojet Inlet Screen
Abstract
Results are presented of an investigation to determine the static-pressure losses and total-pressure distributions of a turbojet inlet screen. The screen which consists of 31 circular vanes supported by 12 radial struts, was tested in two configurations: one having the vane leading edges square and rough and the other having the vane leading edges rounded. The results of the investigation indicate that pressure losses increase rapidly with increasing weight flow, and slight radial and circumferential variations are present downstream of the screen. The rounding of the vane leading edges reduced static-pressure losses considerably and brought about slight improvements in total-pressure patterns.
