Abstract

Studies on high-speed phenomena, occurring in a closed liquid-filled tank as a result of its perforation, is of great interest from both a theoretical and practical point of view. Processes of that kind are usually being registered by x-ray recording and high-speed filming. The photos obtained make it possible to analyze the dynamics of the cavity and the shock wave propagation in the liquid. The authors have developed an experimental installation for the purpose of registering the phenomena caused by perforation of liquid-filled tanks. A high- speed camera acts as a command unit of the installation. The camera is started from a remote desk and when the rotating mirror achieves the desired rotation velocity, the camera signals the gun to fire. The projectile's velocity is measured by an induction velocity meter, and the information obtained enters a synchronization unit, which works out signals for switching on the flash lamp and x-ray apparatuses, as well as for memory oscillograph sweeping. X-ray recording and high-speed registration are accomplished in orthogonal planes. Front and back walls of the tank are steel targets, and side walls are made of transparent material. The movement of the projectile and the cavity dynamics in the liquid are registered by the camera in transmitted light (the camera is placed against a diffusing square -- marked reference screen).
