| 摘 要： | 常见计算螺旋桨滑流流场方法中，很少计及桨叶面附近必然存在的尾涡收缩。本文采用升力面涡格法，建立一种三维自由尾涡模型。构造一种松弛迭代格式，通过迭代获得收缩尾涡模型，计算相应的滑流流场。

| Abstract: | Among the usual methods for calculating slipstream flow-field,it is seldom that the slipstream contraction which definitely existsbehind propeller has been accounted.In this paper lifting surface analysisof Vortex Lattice Method (VLM) is used.A three-dimensional free con-traction model of propeller slipstream is establishe,By formulating arelaxation iteration scheme, the iterations are continued until covergenceof the wake geometry is reached. Lastly, induced velocity field can befound. |
