Projectile starting force loading mechanism in gas gun test device

The utility model relates to the field of gas gun test devices, in particular to a projectile starting force loading mechanism in a gas gun test device, which comprises a projectile blocking component and a pneumatic driving component. According to the device, the bullet blocking assembly and the pneumatic driving assembly are arranged in the gun barrel, the pneumatic driving assembly drives the bullet blocking block of the bullet blocking assembly to exert pressure on the bullet, and therefore the bullet can be launched only when the thrust borne by the bullet exceeds the pressure on the bullet from the bullet blocking block, and stable launching of the bullet is guaranteed. 本实用新型涉及气体炮试验装置领域，具体涉及一种气体炮试验装置中的弹丸启动力加载机构，包括：挡弹组件以及气动驱动组件。本装置通过在炮管内设置挡弹组件和气动驱动组件，通过气动驱动组件驱动挡弹组件的挡弹块对弹丸的压力，从而使得只有弹丸受到的推力超过挡弹块对弹丸的压力时，从能进行弹丸的发射，进而保证了弹丸的稳定发射。
