A design method for high efficiency propeller was presented. This method could calculate the geometric characteristics of maximum efficiency propeller

including the chord distribution

pitch-angle distribution

efficiency

thrust coefficients

torque coefficients and power coefficients based on the given flight velocity

rotating speed of propeller

thrust

diameter

blade number and airfoil. The propeller of an aircraft was designed using the parameters under climbing and cruise conditions

respectively. The chord distribution and pitch-angle distribution were obtained. Wind tunnel test of scaled model of propeller (diameter 0.84m) was carried out. The test results show that cruising efficiency of propeller is 83.02%

and climbing efficiency is 79.13%.
