应用升力面理论涡格法和面元法，建立了拖式吊舱推进器非定常水动力性能的数值计算方法。
Based on potential flow theory, a numerical method is proposed for predicting the steady and unsteady hydrodynamic performances of puller type podded propulsors.
在波浪动力的理论和实践的基础上，促进了浪翼和鱼尾型推进器的深入研究。
The research of wave-wing type and fishtail type propellers has been promoted based on the theory and practice of wave-mechanics.
因此，移动的距离是不一样的，因为推进器的“滑动”背后的理论距离，它应该与每个旋转旅行。
Therefore the distance traveled is not the same, since the propeller is "slipping" behind the theoretical distance it should travel with each rotation.
因此，用无刷直流电动机代替永磁直流电动机作为海洋水下机器人的推进器，无论是理论上还是实际上都具有重大意义。
So, to use permanent magnetic brushless DC motor as the propeller of the ocean robot instead of the permanent magnet DC motor has a great significance both in theory and in practice.
