Abstract
In the Phase I SBIR a cartridge case that is compatible with both Rarefaction Wave Guns (RAVEN) and conventional gun systems was developed. A baseline cartridge design was developed for a 105 millimeter gun that will allow the breech venting to occur when used in a RAVEN gun. A 40 millimeter subscale test fixture (Phase I Option) and associated cartridge case were designed (Phase I Basic) so that experimental testing can occur during the Phase II program. In Phase II, proof of concept testing of the cross compatible cartridge case design will occur. Cartridge cases for the 40 millimeter cannon will be modified to incorporate the vent design developed during Phase I and tested at Veritays firing range. Finite Element Analyses and interior ballistic simulations will be used to support the experimental testing and guide the design process. The results of testing, combined with the analytical results, will be used to refine the cartridge case design. A scalability study will be performed to assess the applicability of the cartridge case design to calibers other than 105mm and 40mm. A manufacturing study will also be performed to assess fabrication methods, material selection, and production costs.
