ABSTRACT (Continue on reverse side It necessary and Identify by block number) 



Analysis and numerical results are presented for the design of a 

 system of wide-bladed thin lifting surfaces rotating at constant angular 

 velocity in an axisymmetric onset flow field. Blade sections may be located 

 arbitrarily in space. General chordwise and spanwise loading functions are 

 available as well as a variety of thickness forms. In addition to the final 

 meanline and pitch distribution determined from a chordwise integration of
