某电子设备机载吊舱的气动特性分析

采用计算流体力学软件Fluent开展了某飞机机身外挂吊舱的三维气动性能研究， 得到了外挂吊舱的表面流速/压力分布、吊舱的尾流、飞行阻力，以及吊舱的偏航力矩等信 息。根据气动计算结果，就吊舱的强度、尾流、偏航力矩等影响飞行安全性的问题展开了讨 论。研究结果和试飞一致显示该电子设备外挂吊舱的气动外形是良好的，吊舱的设计是成功 的，可供同类产品设计提供参考。

Aerodynamic analysis of an airborne equipment pod

By using the computational fluid mechanical(CFD) software Fluent,the 3D aerodynamic properties about an airborne equipment pod is investigated.The information about the surface press distributation,tail airflow,flight draft,and yaw moment of the airborne equipment pod is obtained.According to the information,the strength,tail airflow,yaw moment of the equipment pod are discussed.CFD computation and flight test show that the presented pod is excellent in aerodynamic properties,as well as successful in design,which provides a reference for the design of similar products.
