Abstract:

Apparatus for suppression of water flow noises in connection with a keel mounted sonar dome. A solution of water soluble polymer is ejected through a series of holes along the leading edge of the sonar some under forward movement of the ship. The concentration and flow rate is chosen to bathe the dome in a very dilute dispersion of the order of 10 parts per million by weight of the poly mer. Author
