Abstract:

A set of advanced blading has been designed for a 5-stage high speed research core compressor. The blade profiles were aerodynamically-tailored using a sophisticated S1-S2 flow calculation system, developed at RAE Pyestock, which incorporates an inviscid viscour blade to blade code. The design and measured performance of the compressor are compared with an initial conventionally-bladed 4-stage version. The new design achieved a peak level of polytropic efficiency approaching 91, a substantial improvement on the initial version.
