20. ABSTRACT (Continue on reverae aide It neceaaary and Identity by block nuntber) 



A procedure and numerical results are presented for the prediction of 

 the steady pressure distribution on a rotating propeller blade surface 

 based on lifting surface theory. A computer code, named the Propeller 

 Steady Pressure (PSP) program, has been developed by extending the existing 

 propeller analysis program, PSF, based on vortex/source lattice techniques, 

 developed at the Massachusetts Institute of Technology. Predictions by
