    摘要:

    建立完善的螺旋桨绕流理论异常困难,这一方面是由于螺旋桨流场整体旋转性、非定常非线性、三维效应、气流粘性、涡桨干扰等原因;另一方面是螺旋桨流场的流场结构有待于进一步认知。文章采用CFD方法对螺旋桨的瞬态流场结构进行了重点研究,详细绘制了自启动瞬间直至充分发展的螺旋桨瞬态流场结构图及所受气动力的变化图,分析了流场变化特性及其对升力的影响。

    Abstract:

    The establishment of a perfect theory for the propeller flow field has been a hard job up to now. Firstly, the propeller flow field has many complicated characters such as the entire rotation, the unsteady and nonlinear characters, the 3-D effects, the interference between the vortex and the propeller, and so on. Second, the structure of the flow field hasn’t been well known. In this paper, the aerodynamic performance of the instantaneous propeller flow field was studied. The detailed flow field structures and the evolution of the aerodynamic forces were drawn. The characters of the flow field and its effects on lift and moment were analyzed.
