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%
