Book Description
Windmilling tests on a two-stage transonic compressor with a design over-all pressure ratio of 1.85 produced the following results. The maximum windmilling equivalent speed was 30.2 percent of design speed, and the maximum windmilling equivalent flow was 57.4 percent of the design flow. The maximum flow was limited by choking in the last stator passage. A method was developed for estimating maximum windmilling speed and flow from known compressor design values and geometry for a compressor with exit stators. The method, which is based on the results of the analysis of the windmilling data, predicts the maximum windmilling equivalent speed within 3.3 percent and the maximum windmilling equivalent flow within 0.4 percent.
