  • The paper has improved the existing lifting - line and lifting - surface design method by including the rake and skew and solving the optimum circulation distribution with the optimum theory . the blade geometry is expressed with b - spline for the lift - surface method . the boundary condition on the blade is transformed to minimize the summation of the square of normal velocities , the fair blade geometry can be obtained by present technique and the design quality is better
    改进了现有的升力线和升力面设计方法,在升力线设计中计及桨叶的纵倾和侧斜的影响,用优化理论求解最佳环量分布,升力面设计中用b样条来拟合桨叶,将物面边界条件转化为求法向速度分量的平方最小,由此可得到光顺的桨叶几何形状,提高和改进了设计质量。
  • The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller . the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution . for highly skewed propeller , the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface , which result easily in incorrect calculation results of velovity on blade surface , even in iteration divergence and calculation failure . a “ non - conventional grid ” is developed to acoid these problems . this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller . the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure . by sample calculating , the obtained results are satisfied the experimental data
    采用面元法预报大侧斜螺旋桨水动力性能,螺旋桨表面及尾涡面离散为四边形双曲面元,每个面元上布置等强度源汇和偶极子分布.对于大侧斜螺旋桨而言,桨叶表面采用常规的等半径网格划分方法在近叶梢处将导致大展弦比、大侧斜和扭曲面元,这容易使桨叶表面速度的计算结果不正确,甚至会导致迭代过程发散及计算失败.文中建立了一种“非常规网格”划分方法,能有效地解决大侧斜螺旋桨的计算和收敛问题.桨叶随边处通过迭代实现非线性等压库塔条件
