本文在“飞机投外挂时的动态响应及其地面飞行模拟”的研究基础上,对垂直机动飞行时飞机投外挂后的动态响应进行研究。文中推导了该状态下的运动方程,采用积分变换方法,求得动态响应的解析解,并以歼7、歼8为例,进行了计算.计算结果表明:投放同样的外挂,垂直机动飞行时运动初期的动态响应与平直飞行时基本一致.飞机作垂直机动飞行时投外挂对飞行影响不大,符合规范要求.
Based on the research of the dynamic response of the aircraft and its ground flight simulation, the dynamic response of the aircraft during the vertical maneuver flight is analyzed. The equations of motion are deduced in this paper, and the analytic solution of dynamic response is obtained by using the integral transform method. Taking the J-7 and J-8 as examples, the calculation is carried out. The calculation results show that when putting the same plug-in and vertical maneuvering The dynamic response at the beginning of the movement is basically the same as that of the straight flight.It has little effect on the flight when the aircraft is used as a vertical maneuvering flight and meets the requirements of the code.
