Description
Summary:The recently proposed light Future Combat System (FCS) vehicles require a highly lethal cannon with greatly reduced recoil momentum. A novel approach to this problem was proposed by Kathe, which utilizes a RArefaction waVE guN (RAVEN) propulsion system to significantly reduce the recoil momentum and barrel heating. To accurately assess the effectiveness of this approach, a Navier-Stokes flow solver was developed to calculate the internal ballistics of this unconventional hybrid propulsion system. The results of the internal ballistics analysis for the current 120 mm M256 firing an M829A2 Kinetic energy round indicated that the proposed system could theoretically reduce the recoil momentum by 75% and reduce the barrel heating by 50%'.
