Propulsion System for Confined Space Projectile Launchers

Southwest Services LLC Confined Space Projectile Launcher is a derivative of a conventional shoulder fired recoilless launcher incorporating improvements to dampening the energy and overpressure within the exhaust gases. Our CSPL will increase the muzzle energy of the launcher which will have a corresponding increase in the exhaust gas energy, but by using our innovative approach to dampening the exhaust gases our system will have a net decrease in the back-blast overpressure to produce an operator safe environment for confined space launches. Our Phase I effort will include a basic launcher design defining all key system parameters, a detail computational model of the system to analytically verify our systems compliance with the SBIRs noise limit requirement, and test firings simulating the rearward ejection of the launchers exhaust gases to evaluate fundamental characteristics of our unique exhaust gas dampening feature to verify its functionality.
