| 摘 要： | 本文采用CFD方法分析了悬停状态下涵道尾桨的流场特性。该方法以动量源代替桨叶对流场的作用来分析涵道尾桨的气动特性。即通过编写UDF程序把动量源加入到N-S方程中,建立了一套适合于直升机涵道尾桨流场和气动特性的CFD数值模拟方法。然后利用所建立的数值模拟方法对某个涵道尾桨进行分析,并与试验结果进行对比以验证数值方法的有效性。

| Abstract: | The flow field characteristic of a helicopter ducted tail rotor in hovering were analyzed using CFD method in this paper.The momentum-source term with functional relationship to the local flow conditions represented the spinning rotor in flow field and were added to the N-S equations by UDF procedure.It sets up the CFD methods which fits to analysis the flow field and aerodynamics characteristic of a helicopter ducted tail rotor.Then,it analysis a helicopter ducted tail rotor with the present method and con... |
