Abstract

A analytical technique for predicting the aerodynamic performance of propellers with tip devices (proplets) using vortex lattice method shows that the ideal efficiency of a fixed diameter propeller can be improved by 1-5%.By suitable orientation and sweep of the proplet, the noise analysis method pr
