Abstract

The principal problem dealt with is the derivation of a method for computing the optimum pitch distribution of a lightly loaded, sweptback propeller. The method is based on an extension to the work of Glauert as presented in Volume IV of the Durand series. A complete calculation is carried out for a swept propeller in which the resultant velocities along the blade vary through the transonic regime. The analytical work is simplified by the use of the calculus of variations. A survey of the German literature on this topic is included along with a complete discussion of the aerodynamic parameters to be considered in making of such a design.
