| 摘要: |
| 对无人机投放航空炸弹过程中载机、航弹间的气动干扰特性和航弹运动规律进行了数值仿真研究。为得到更加精确地结果,对现有仿真模型进行了改进:考虑了动力学模型中无人机平台在投放过程飞行姿态变化项的影响。应用此方法模拟了典型状态下基于察/打一体无人机平台的武器投放过程,以获得该过程中更为准确的无人机/航弹运动速度、姿态轨迹,及气动力等信息。算例表明基于改进模型得到的载机、导弹之间的气动干扰和其姿态等结果更加精确。 |

| Abstract: |
| We simulated the UAV-weapon separation process with the improved computational fluid dynamics method which comprehensively considered the flying status of both UAV and released weapon. In order to study the aerodynamic interference and the rules of weapon movement more accurately, dynamic grid approach was used coupled with an unsteady Euler flow solver. 6-DOF models of both UAV and weapon were fully integrated into the CFD solution procedure to determine the body dynamics. And we presented the simulation results of a weapon launching process using developed numerical methods. Major trends of the separation were captured. The computation results and their analysis showed preliminarily the accuracy of the improved method. |
