Calculation of the optimum pitch distribution of a propeller with sweepback

[摘要] 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.
