STATIC TESTS OF A CW-351 SONAR DOME UNDER SIMULATED HYDRODYNAMIC LOADING

Abstract

Structural tests were conducted on a CW-351 sonar dome by simulating the steady-state hydrodynamic forces encountered in a seaway by multiple static loads in the laboratory. Computed steady-state hydrodynamic forces for angles of yaw of 0 deg and 10 deg and for shi p speeds up to 35 knots were simulated and applied to the sonar dome. In large areas of the dome, stresses were relatively low. The areas of high stress were at the juncture of the bottom and sides of the dome. Nowhere did the measured stresses exceed the yield strength of the material. The tests indicate that, for domes not subjected to appreciable slamming forces, reinforcement could be more effectively distributed and a lighter dome of adequate strength would still result.
