飞机在各种机动飞行过程中,因任务需要从飞机中弹抛一些物体。本文以歼××机在上升、俯冲、倒飞、定常协调侧滑、盘旋等各种机动飞行为基准状态,受到约等于飞机重量量级的扰动为例、讨论该情况下的运动方程:受扰动后动态响应计算;飞机弹抛物体时安全飞行包线的确定等有关问题。通过讨论表明飞机弹抛物体时的安全飞行包线应受到飞机弹抛物体后,扰动运动参数中升力系数(迎角)、高度损失、过载、侧滑角等参数的制约。
Plane in a variety of maneuvers during flight, because the mission needs to throw some objects from the aircraft. In this paper, the J-type aircraft in the rise, subduction, inverted flight, steady coordination of sliding, hovering and other maneuvering flights as the benchmark state, subject to approximately equal to the weight of aircraft disturbance as an example, to discuss the case of motion equations: Dynamic response after perturbation calculation; flight safety patrol aircraft to determine the envelope and other related issues. The discussion shows that the safety flight envelope when the aircraft is launching the parabolic body should be controlled by such parameters as lift coefficient (angle of attack), altitude loss, overloading and side slip angle in the parameters of the disturbance motion after the projectile is thrown off by the aircraft.
