This paper presents a practical method to design propellers. In the method, the form of a propeller blade section profile is represented by eleven parameters. The parameters can be divided into three groups. (1) parameters to determine strength (2) parameters to affect largely pressure distribution on blade surface (3) other parameters Values of second group parameters are determined by solving simultaneous equation under prescribed pressure distribution. Coefficients of the equation are derived from solution of propeller analysis method such as Koyama's lifting surface theory. By the presented method, it is possible to design propellers with high performance in cavitation and efficiency, under various design conditions including wake distribution.
