平流层飞艇高能激光武器防御弹道导弹

防御弹道导弹逐渐受到世界各国的重视，扩大拦截窗口是重要的发展趋势之一。平流层飞艇有可能通过艇载激光武器或者中继反射地基激光两种方式拦截自由段弹道导弹，为评估这两种方式的拦截效果和可行性，本文分析了平流层飞艇搭载高能激光武器的可能性以及中继反射作战方式的特点，建立了激光烧蚀模型，采用数值计算方法对激光的烧蚀效果进行了研究，结果表明平流层飞艇部署位置应距离导弹发射点800～1000km，平流层中继激光飞艇能够在短时间内引爆弹头，艇载激光武器采用烧蚀弹头防热层的方法同样可以达到拦截弹道导弹的目的。

Defending Ballistic Missile using High-Energy Laser Weapon basing Stratosphere Airships

The importance of ballistic missile defence is known by many countries. One main trend is extending the intercept window. Stratosphere airships can intercept ballistic missile through two ways of airship borne laser and relay ground base laser. In order to evaluate the intercept capability and feasibility of these ways, the possibility that stratosphere airship can bear high-energy laser weapon and the superiority of relay mode are analyzed in this paper, and the laser ablation model is built, furthermore the laser ablation effect is computed. The results show airship should deploy 800~1000km away form the missile launch point, and the laser-relay airship will detonate warhead rapidly, while airship borne laser can achieve same interception effect by ablating the thermal protection layer.
