在实验条件不成熟和计算性能不够好的情况下,提出了一种研究螺旋桨气动性能的方法。首先对叶素周围的流场进行数值模拟,分析叶素的气动性能并得出叶素升阻系数,然后差值得到叶素升阻系数沿桨径的连续分布,再利用叶素理论对螺旋桨的整体气动性能进行分析。研究表明,所提出的研究方法不仅可以对叶素周围流场进行详细的分析,还能够较好地分析螺旋桨整体气动性能。对所研究的螺旋桨而言,发生严重气动分离并伴有气动振荡现象的部位并不在桨尖处,而是在桨径前半部分。 In the case of immature experimental conditions and poor computational performance, a method to study the aerodynamic performance of propeller is proposed. Firstly, the numerical simulation of the flow field around the blade was carried out. The aerodynamic performance of the blade was analyzed and the coefficient of resistance of the blade was obtained. Then the difference was obtained to obtain the continuous distribution of the blade drag coefficient along the blade. Then the blade aerodynamic performance Analyze. The research shows that the proposed method can not only analyze the flow field around the leaf element in detail, but also analyze the overall aerodynamic performance of the propeller. For the propeller studied, the area where severe aerodynamic separation with aerodynamic oscillations occurs is not at the tip of the paddle but at the front half of the paddle.
