【Abstract】 A new method is developed in the present paper for solving an aerodynaanie hybrid problem of profile cascade on S1 stream-surface of revolution by employing stream function equation on non-orthogonal coordinate system. For this ’kind of problems the shape of a portion of the blade profile is unknown. The remainder is determined by a giving prescribed velocity distribution. Four examples of Wade caseades have Seen carried out to examine this method. It is shown that the calculation method presented herein cam be used as a powerful tool together with aerpdynamic oprtimization method for blade cascade design.更多还原
