WTF-48 Single Rotor Compressor Development.
Abstract
Development of the reduced scale WTF-48 lift fan engine was continued under this program. The objective of the program was improvement of the pressure ratio, efficiency and diffusion of the compressor rotor. This program investigated the effects of deblunting and sweep of the rotor trailing edge and modification of the passage area schedule and wall contours. The modifications investigated in this program did not produce increased rotor pressure ratio or efficiency. An increase of 11% in rotor static pressure, accompanied by a 20% reduction in diffuser losses, was accomplished. This improvement produced a 5 point increase in stage efficiency of the compressor.
