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

Abstract

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.
