The Pressure Distribution on Four Sonar Dome Bottoms

摘要

The effect of changes in the shape of sonar dome bottoms on the pressure distribution over them was investigated. Wind-tunnel tests were made on models with bodies of EPH shape. The transverse sections of the bottoms were: Dome A-Circular; Dome B-Elliptical, 3 1/3 to 1; Dome C-Elliptical, 1 2/3 to 1; Dome D-Flat with rounded corners. Dome C appeared to have the maximum permissible flattening to maintain equal cavitation speeds on the body and the bottom. (Author)
