(Block 20 continued) 



an appropriate combination of geometric variables and induced velocities, 

 additional information not available from other existing techniques 

 includes pressure distributions and surface metrics for an orthogonal 

 streamline coordinate system on the blade surface, as defined in the 

 Appendix. The induced velocity field on the blades is derived from the 

 principal value of a singular integral; the evaluation of this integral 

 is discussed. The predictions are generally supported by experimental 

 data. A new term in the analysis arises from a radial onset flow component 

 and an example illustrates its importance in design. Sufficient 

 information for manufacture is obtained for computer run times from 400 to 

 1200 seconds on the Burroughs 7700 high-speed computer.
