摘　　要：为了验证舵前进流的选择对桨-舵系统定常性能的影响,计算了三种舵前进流下的桨-舵系统性能,结果表明,不同进流状态对桨-舵系统性能预报结果十分接近。文中还验证了舵面上诱导速度不取周向平均时对桨-舵定常性能的影响,并对这样计算的诱导速度峰值使用Lagrange插值处理。与试验值比较表明,在计算桨-舵定常性能时,以此方式来计算舵上诱导速度也有效。Three entrance velocity conditions are considered in the calculation of performance of propeller-rudder system performance to verify the influence of entrance velocity on its steady performance. The results show that the system has similar performance with different inflow conditions. This paper also verifies the influence of non-averaged induced velocity on the steady performance of propeller-rudders, and calculates the speed peak value by Lagrange interpolation. In comparison with the experimental results, this calculation method of the induced velocity on the rudder is testified to be effective in the computation of the propeller-rudder system steady performance.
