摘要：

To solve the problem of sabot separation in experiments using light gas gun with short target chamber, a new type of sabot and its separation device were designed. The relation between projectile velocity, together with sabot operating range, and charge pressure in sabot separation container, length of the container, and initial velocity was studied through experiments and simulations. Results show that under the pressure of pumped nitrogen gas of about 0.2~0.5 MPa, the sabots can be effectively separated during flight of projectiles in the container at the velocity of 1~2.5 km/s. The pose and the stability of projectiles before impacting targets are satisfying for experiments of light gas gun with short target chamber. The separation angle increases with the increase of charge pressure; and the higher the projectile velocity, the more obvious the separation effect. The short separation container is more advantageous in decreasing the ballistic error caused by aerodynamics.
