查询词典 ballistic curve

Based on researchful results of two former students, we take the influences of thermochemistry reaction, mutual disturb and unsymmetrical instance into account. Secondly, the paper simulates the transient thermal response of projectile according to the simulation software, and discuss the ablation regulation when the projectile is in different initial velocity, in different shape, in different angle of attack condition and in different material condition. Thirdly, the effect on the aerodynamic characteristic and the outer ballistic characteristic after the ablation of hypersonic projectile has been analyzed.

在前面两位师兄研究成果的基础上，研究了超高速弹箭组合体在考虑热化学反应、存在攻角影响下的的气动加烧蚀数学模型；然后对不同条件下的烧蚀过程进行计算，分析和总结出在不同外形和不同材料条件下弹体和弹翼的烧蚀规律；紧接着分析了在不同的烧蚀情况下，它对飞行中弹箭的气动力和外弹道特性的影响，从而为今后的超高速弹箭设计提供指导和帮助。
