OPTIMUM PROPELLERS WITH CAVITY-DRAG AND FRICTIONAL-DRAG EFFECTS
In a variational problem for the optimum pitch distribution of a propeller, the Euler differential equation with Munk's displacement theory is utilized. Effects of frictional-drag and cavity-drag are considered through simple approximate relations of drag-lift ratio and the circulation. Simple relations between the optimum pitch distributions and the drag-lift ratio are obtained both for free-running and wake- adapted propellers.
