The submarine noise detected by sonar consists of two parts : propeller - generated hydro - dynamical noise, which can be greatly reduced by improving the submarine rear shape ; radiated noise from the submarine structure excited by the centrifugal forces ( moments ) of rotatory machine, which is more complicated and influenced by many factors
聲納所探測的潛艇噪聲包括兩部分,一是螺旋槳運轉帶來的水動力噪聲,二是潛艇主機工作時產生的不平衡力和力矩引起潛艇結構振動,帶動流場振動從而輻射噪聲。通過改進潛艇尾部線型設計,已將水動力噪聲降到比較低的程度,而結構噪聲則復雜得多,與許多因素有關。With the progressive development of underwater acoustic detection and acoustic - guided weapons, more advanced requirements are imposed upon the acoustic properties of submarines
隨著水聲探測潛艇的手段和方法以及帶有聲制導的水下武器的不斷完善,對潛艇的聲學性能的要求越來越高。
