| Abstract: | This paper is concerned with the problem of sound radiation from the body of surface ship derived by surface pulsative force of the propeller.The sound radiation model is established and the expression of far-field sound pressure is obtained therefore.Finally,the example of numeric result for typical ship with 4-blade propeller is given. |
