20. ABSTRACT (Continue on reverae aide If necessary and Identify by block number) 



Experiments are described in which the pressure distribution on two 

 model controllable-pitch propellers was measured. The pressure was measured 

 at 40 locations on the blade surface with the propeller operating in both 

 uniform and inclined flow. The discussion of the experimental technique 

 includes a description of the hardware and data analysis systems.
