摘　　要：机载导弹发射系统在导弹发射后,安全拉索的气动力影响载机性能。利用流体力学仿真软件Anasys-Fluent建立安全拉索流场及气动力特性的数学模型,并对不同航速、海拔高度及不同摆动角度条件下安全拉索的气动流场及受力进行了数值仿真。结果表明:飞行高度对安全拉索的受力几乎无影响;摆动角度对安全拉索的气动力影响较大,摆动角在20°附近时气动拉力最大;当航速为1.0 Ma时,因在弹肩上出现音障,使安全拉索的气动拉力急剧上升至6倍左右,仍在理论值范围内。For an airborne missile launching system,the aerodynamic force of the safety cable affects the performance of the carrier after missile launch.The mathematical model of the flow field and aerodynamic characteristics of the safety cable is established by using the hydrodynamics simulation software Anasys-Fluent,and the aerodynamic flow field and aerodynamic force of safety cable under different speed,altitude and swing angle are numerically simulated.The results show that the influence of flight height on the stress of safety cable can be ignored;the swing angle has a great influence on the aerodynamic force of the safety cable,and the swing angle of the maximum aerodynamic tension is around 20°.When the speed is at 1.0 Ma,due to the sound barrier on the elastic shoulder,the pneumatic tension of the safety cable rises sharply to about 6 times,which is within the theoretical range.
