Visualization of high-speed interaction of bodies in water

The work presents opportunities of hydroballistic complex for studying the characteristics of movement super-cavitation model (SCM) on the length of waterway to 10 m. Gunfire of SCM implemented by this complex allows to study movement and collision of the different masses of SCM with underwater obstacles at subsonic, transonic and supersonic velocities in water. During the movement of SCM different masses the behavior supercavity was investigated

Experimental and theoretical research of the interaction between high-strength supercavitation impactors and monolithic barriers in water

The article describes experimental and theoretical research of the interaction between supercavitating impactors and underwater aluminum alloy and steel barriers. Strong alloys are used for making impactors. An experimental research technique based on a high-velocity hydro-ballistic complex was developed. Mathematical simulation of the collision the impactor and barrier is based on the continuum mechanics inclusive of the deformation and destruction of interacting bodies. Calculated and experimental data on the ultimate penetration thickness of barriers made of aluminum alloy D16T and steel for the developed supercavitating impactor are obtained

Experimental research of cavity geometry behind high-speed bodies in water

At high speed launching of bodies via smoothbore throwing facility into water, a stabilization of bodies was experimentally achieved due to periodical interactions of body contour with the cavity boundaries. If the body contours are not exceeding produced cavity boundary, drag force localized mostly at nose part of a body, which calls “cavitator”. Based on this, it will be rational to take into consideration cavity shape when designing contours of bodies

Determination of limit velocities of supercavitating motion of strikers from various materials in water

Experimental-theoretical investigations have been conducted into underwater supercavitating motion of cone strikers from various materials in a broad range of velocities. An estimate of the range of strikers' velocities has been performed for the implementation of their nondestructive entry into water and motion in it in a supercavitating regime. A possibility of an accurate hit by supercavitating strikers on underwater barriers in a supersonic range of motion velocities has been shown
