In particular, interior noise levels are influenced by hydrodynamic coincidence, which occurs when the convection speed in the turbulent boundary layer matches the flexural wave speed in the ship hull panels. Calculation of the structural vibrations and of the noise radiated inside the dome ...
As the dry dock filled with water and the ship began to float again, ST1 Andy Anderson told me to go flood the Sonar Dome in preparation for getting underway. I told Cole to grab a bucket and a Crescent wrench and come with me. He hadn’t heard the assignment so when he asked what...
SUBSTANCE: antennas are placed in domes in the form of flexible rubber envelope of varying thickness filled with water in working state. EFFECT: improved efficiency of flexible dome due to air space built up in its stern part for shielding antennas from noise produced by carrier ship propeller....
