Abstract:

A method was derived and a computer program formulated which utilizes a vortex-lattice lifting surface representation to model a statically operating propeller and to compute its performance. The computer program has been written to yield propeller performance characteristics for a prescribed blade geometry the direct problem or to yield blade camber distribution the indirect problem. All of the results described were obtained for the direct problem. Performance characteristics, including propeller thrust and torque coefficients, were computed for three propeller configurations and were compared with test data and with results computed using lifting line theory.
