Abstract : The analytic concept and capabilities of a computer program for predicting performance of a fan/compressor with arbitrary flow division are described in this volume, Part VII. It further presents comparisons of YTF-33 fan/compressor test data with program predictions. Finally, the results of parametric studies to evaluate the effects of the front fan and the splitter lip on the compressor performance at different bypass ratios are presented. It was concluded that the program is a valuable tool for predicting fan/compressor performance at off-design conditions, and for determining modifications that would improve performance. (Author)
