| 摘 要： | 浮标能否安全出舱是某型飞机投放浮标试验中的关键环节。为解决这一难题，采用直角切割网格技术及有限体积法对浮标所处的流场及其所受的气动力进行了数值模拟，计算了浮标在飞机上投放离机时的运动轨迹，根据计算结果对浮标出舱的安全性进行了分析，最后对浮标提出相应的改进建议。

| Abstract: | Safely dropping is the key problem in the experiment of releasing buoy from aircraft. To solve the problem,this paper uses technology of Cartesian Grid and Finite Volume Method to simulate the flow and the aerodynamic forces of buoy. We compute the moving track for buoy dropped from aircraft. The safety of buoy dropping is evaluated and analyzed according to the computation result. We also give some suggestions to improve the design of buoy. |
