有关资料~[1]指出:弹道环起改善跨音速段弹道稳定性作用。下面我们将具体讨论弹道环究竟起什么作用。资料~[2]介绍,弹道环对气动参数影响,是阻力系数明显增加,升力系数减小以及静稳定储备量增加。在风洞试验中,通过对弹道环的模型(涂油)进行观察,可以看到在离头环一定距离处形成明显分界线,分界线前方模型表面上的液体向前方流动,分界线后面的液体向后方流动。是因为气流在头环处开始脱体,而在离头环一定距离的地方又重新附体的缘
Relevant information ~ [1] pointed out: ballistic ring to improve the transonic section ballistic stability. Below we will discuss in detail what exactly is the role of ballistic rings. According to the data [2], the influence of the ballistic ring on the aerodynamic parameters is a significant increase of the drag coefficient, the decrease of the lift coefficient and the increase of the static stability reserve. In the wind tunnel test, by observing the model of the ballistic ring (oiled), a clear demarcation line is formed at a distance from the head ring, the liquid on the model surface in front of the demarcation line flows forward, and the Liquid flow to the rear. Because the air flow at the head ring began to take off, while in a certain distance from the head ring and re annex body edge
