Firing Test of a Composite Gun Tube Support for the Multi-Role Armament and Ammunition System

摘要

The Future Combat Systems Multi-Role Armament and Ammunition System (FCS-MRAAS) Swing Chamber Launcher uses a rotating swing chamber to achieve a high firing rate while simplifying design and minimizing space claims. Since the chamber is detached from the tube, the tube is held only where it screws into the breech ring and tube deflections are not kept to an acceptable level. To overcome this problem, a thin shell carbon fiber tube support was designed that connects to the breech ring and the gun tube. This paper will discuss the building, assembling, and firing of two composite tube supports.
