Abstract:

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 13 to 1 Dome C-Elliptical, 1 23 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
