摘要
本文建立了在大气紊流作用下飞机或外挂的运动方程,阐述了考虑母机流场气动干扰时外挂所受的气动力和力矩的计算方法,提出了外挂投放后计算相对母机的运动轨迹和判断安全性的方法,最后以某歼击机投放机身下空副油箱为例,检验了在大气紊流场中投放该外挂的安全性。
The equations of motion for both aircraft and external store in atmospheric turbulence are established in this paper. The calculating method of aerodynamic forces and moments acting on an external store in consideration of the aircraft interference aerodynamic field is described. The method of calculating the external store trajectories relative to the aircraft and the method of determining the separation safety after the release of external store are presented. At last, taking the seperation of an empty auxiliary fuel tank under the fuselage of a fighter as an example, the separation safety of this external store in atmospheric turbulence field is investigated.
