摘　　要：机载光电吊舱所受的气动载荷会对其自身的运动特性产生影响,受到了结构设计人员的高度重视。传统的计算方法是基于经验公式来计算风阻力矩,有很大的局限性。采用计算流体力学方法计算吊舱的风阻力矩。基于Workbench平台获得吊舱在方位和俯仰运动下的风阻力矩结果,同时给出了不同角度下的变化趋势。该方法具有在较短时间内给出计算结果的优势,满足工程任务节点高度时效性的需要,也给设计人员提供了很好的参考。Airborne optical pod suffered aerodynamic loads will have an impact on its own motion performance. Structur-al designer paid high attention on it,the traditional method of this based on empirical has many limitations,the CFD method to calculate the drag torque of pod is attempted to use in this paper. The result of air resistance moment of pod under the azimuth and elevation movement is obtained in simulation using workbench platform,and the results arre given in relatively short time, the engineering task node requires can be met in a high degree of timeliness. A good reference is also brought for designers.
