【Abstract】 In this paper, the computer program established on modern propeller numerical lifting surface theory, i.e. vortex lattice method, is checked by experimental data and then improved for accuracy of calculation. By applying the improved program a propeller was designed and tested with its model. The results indicated that the powering and cavitating performance satisfied design requirements and further proved that the programs are reliable which can fulfill propeller design, propeller characteristics calculation, optimum skew selection and drawing propeller design plan etc.更多还原
