Research on the sealed launching technology of underwater gun

Abstract With the progress of military technology, underwater combat capability world’s major naval powers has developed rapidly. In order to effectively deal with threat, related technology research gun is carried out based on supercavitation technology. Due particularity launch environment, still faces many problems. this paper, sealed launching taken as object. By comparing submerged and air curtain launching, advantages are analyzed, muzzle sealing interior ballistic continuous stable water entry preliminarily studied. Opinions suggestions put forward for technologies, which can provide reference engineering practice in future.
