NOISE ABATEMENT SYSTEM FOR A GUN

摘要

A noise abatement apparatus (20) for a gun (12) having a gun tube includes a plurality of generally spherical pressure vessels (22, 24, 26), with a first pressure vessel having an end adapted to be coupled to the gun tube. The pressure vessels are adapted for attenuating pressure waves caused by a firing of a projectile by the gun and for being mounted on a surface. At least two of the pressure vessels are in general alignment with one another. The apparatus may further include at least one connecting portion, a catcher for entrapping particulates and for permitting the projectile to pass, and at least one orifice plate or baffle for aiding in attenuating the sound. A noise abatement system includes the apparatus and a platform on which the apparatus is mounted. The system may further include an actuator (48) for moving the apparatus along a track that is in physical commucation with the platform.
