| 摘 要： | 为选择全方向推进器的设计参数,运用CFD软件预报全方向推进器非定常水动力性能的方法,根据全方向推进器的工作原理建立仿真计算模型并进行网格划分,给出了计算结果。分析表明,周期螺距角和纵倾角决定了全方向推进器所能产生的横向力的大小,而整体螺距角则对全方向推进器的轴向水动力性能起决定性作用。 |
| 关 键 词： | 全方向推进器 整体螺距角 周期螺距角 纵倾角 |

| Abstract: | To select parameters of the variable vector propeller(VVP) for design,the method for prediction of the unsteady performance of VVP by CFD software was studied.According to the working principle of the VVP,the computational model of VVP was built,and the grid was generated.The influences of collective pitch angle,cyclic pitch angle and rake angle on the axial performance and transverse performance of VVP were analyzed.The numerical results showed that the value of transverse force depends on the cyclic pitch... |
