Launching Noise Reduction for Underwater Weapon Launch Tube

We illustrate the importance of noise reduction of underwater weapon launch tube, and summarize the classification of underwater launch tube and the main sources of launching noise. The mechanism of launching noise is analyzed in view of equipment alteration and upgrade based on the current status of domestic weapon launcher and the characteristics of the tube driven by reciprocating pump. A series of methods to reduce launching noise is proposed in low noise design of underwater weapon launcher for the purposes of upgrading the existing launch tubes and designing new launchers.
