Research on the sealed launching technology of underwater gun

Abstract

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