摘要
基于对桨舵干扰的系统研究 ,本文提供了一个桨舵非定常干扰问题的理论计算方法 ,桨采用非定常涡格法 ,舵采用基于速度势的非定常面元法。在时域范围内通过迭代计算考虑螺旋桨和舵的相互影响。文中提供了一些算例考核 ,通过与实验结果对比 ,证明本文提供的方法是可靠的 ,可供实际应用。
Based on the systematical investigations on interactions of propeller and rudder,a theoretical procedure for unsteady performance of the propeller and rudder system is proposed.An unsteady vortex lattice method and a potential based panel method are applied for predicting the unsteady performances of the propeller and the rudder behind the propeller respectively.In this procedure the iteration is needed until the periodical variation of thrust and torque coefficients of the propeller converges.Several examples are performed.Comparisons between the calculated results and the experimental data indicate that the present method is reliable,and maybe put into application.
