基于叶素动量理论和伯努利原理建立桨叶动力学模型,从能量捕获效率最大化原则出发,采用非线性优化方法求解得到桨叶外形参数,并制作出桨叶进行实验测试。结果表明,优化后的桨叶在设计流速附近运行时能获得更大的功率,并更接近理论预测值,可验证该动力学模型的正确性和有效性。 Based on the principle of leaf element momentum and Bernoulli principle, the blade dynamics model was established. Based on the principle of maximizing the energy capture efficiency, non-linear optimization method was used to obtain the blade shape parameters, and the blades were made for experimental testing. The results show that the optimized propeller blade can obtain more power when it runs near the design flow rate, and closer to the theoretical predictions. The correctness and validity of the dynamic model can be verified.
