A flier launched from an electrothermal accelerator 2 is collided against a specimen 53 retained in a sealed specimen receptacle 36, so that impact testing or perforation processing can be effected without disturbing collision environments such as temperature and atmosphere.

Impact testing and processing apparatus electrothermally accelerating

A sabot separator includes a sabot separation cylinder equipped with a pair of rail electrodes extending axially and connected with a muzzle end of a barrel of a projectile accelerator. An electrical power source is connected between the rail electrodes and applies a voltage to the rail electrodes for producing a force in a direction for decelerating the accelerating sabot. When the sabot enters the sabot separation cylinder, an electric current flows through the sabot and the sabot is suddenly stopped by a braking force resulting from the flow of the electric current.
