Abstract

Abstract

A propeller-nacelle interaction analysis has been developed in this paper as a kind of lifting line analysis. It represents the blades by curved lifting lines, taking into Consideration the blade sweep and the effect of the nacelle on the propfan flowfield. The wake model assumes that the vortex filaments occur along stream surfaces. Some corrections have been made to transonic portion of the blade and large solidity cascade portion at hub. Comparison of the results of the design and analysis with those given in references show the method is feasible and effective, Aspects of its improvement are also discussed.
