| 中文摘要: |
| Φ100/30mm口径二级轻气炮主要用于EFP（Explosively Formed Projectile爆炸成形弹丸）、PELE（Penetrator with Enhanced Lateral Efficiency 横向效应增强型侵彻弹）、分段杆条等杀伤元件对各类目标毁伤机理及高应变率材料动态性能等领域的高速、超高速撞击实验研究。该气炮以Φ100mm单级压缩气炮作为首级驱动，加装可拆卸的Φ30mm发射管,实现了一、二级气炮的功能。本文主要介绍了该气炮的高压锥段、发射管、膜片及活塞等关键零部件的结构设计 |
| 英文摘要: |
| Φ100/30mm-caliber two stage light gas gun is mainly used in high velocity and hypervelocity impact experiments in the area such as dynamic performance of materials subjected to high strain rate and damage mechanism of kinds of target shot by EFP（Explosively Formed Projectile）, PELE（Penetrator with Enhanced Lateral Efficiency） and pole of several segments and so on. The device is made up of a 100mm-caliber compressed gas gun as the first-stage drive and a 30mm-caliber launch tube, which can be disassembled, so it can be used as a one-stage or a two-stage light-gas gun. This article mainly presented not only the machinery design of the device's key parts such as high pressure vessel, launch tube, diaphragm and piston, but also adjusting method and some experiments as its application. Now, when the gas gun is used as a one stage light gas gun, it can propel an 20kg projectile to a velocity of 349m/s or propel an 1kg projectile to a velocity of 1157m/s; when it is used as a two stage light gas gun, it can propel an 100g projectile to a velocity of 3005m/s or propel an 400g projectile to a velocity of 1520m/s. |
