由二0二所负责的“先进加榴炮新结构技术”预研课题,“九五”期间研究的适用于模块装药、药包装药和满足快速射击要求的新型炮闩(含底火自动装填)原理样机,最近在“051”基地试验成功。样机以155mm口径为研究试验对象,发射牵引155mm加榴炮药包装药和填砂榴弹,从小号装药低温—40℃到全装药高温+50℃的膛压范围内密封可靠;各种射击条件下机构灵活、动作准确,能满足快速射击要求。
The pre-research project entitled “New Advanced Technologies for Adding Cannon and Part 2”, which was undertaken by 220 Corps, the new type of research project for module charges, drug-packing drugs and rapid-fire requirements that were studied during the Ninth Five-Year Plan period ) Prototype prototype, the recent test in the “051” base successfully. Prototype to 155mm caliber as the research object, the launch of traction 155mm gunded gunpowder and filling sand grenade, from the small charge -40 ℃ to fully charged high temperature +50 ℃ bore pressure sealed within a reliable range; a variety of shooting Under the conditions of flexible body, accurate action, to meet the requirements of fast shooting.
