高超声速弹箭烧蚀对外弹道特性的影响

The Effect on the Exterior Ballistic Characteristics After the Ablation of Hypersonic Projectile

该文根据烧蚀模型计算出弹丸在某一时刻的烧蚀外形及其对应的气动系数 ,利用外弹道模型仿真高超声速弹丸烧蚀后对其外弹道特性的影响。文中所采用的理论。

On the basis of ablation model, the paper calculated the ablation shape of projectile at a certain time, and computed corresponding aerodynamic coefficients.Using outer ballistic trajectory model,the paper simulated the effect on the outer ballistic trajectory characteristics after the ablation of hypersonic projectile. The theory, method and calculation results presented in the paper are valuable for the study of hypersonic projectiles in the future.
