This equipment is a gas gun called Aeroballistic range. Aeroballistic range enables to launch projectile at supersonic by using high pressure He gas. The equipment consists by high pressure chamber, launch tube tube(acceleration tube, ventilation tube, separation tube) and test chamber. Our aeroballistic range has two characteristics. One is rectangular bore launch tube. This tube prevents models from rolling. This is very important to launch projectiles which shape is like airplane. Another is sabot separation system. By employing this system, the chance of launching an experimental model with good attitude is increased.
