现代坦克均安装有集体防护装置,该装置一般是基于车内战斗舱室形成超压的原理达到防护目的的。但在火炮射击时,舱内会出现瞬间负压状态,从而外界染毒空气会乘虚而入,这对乘员是否会构成威胁,本文旨在对此进行安全评估。 根据测试,火炮射击时舱内负压动态过程可用下 Modern tanks are equipped with collective guards, which are generally based on the principle of creating overpressures in the cabin of a vehicle for protection. However, when the artillery firing, there will be an instant negative pressure cabin, so outside air will take advantage of exposure to air, which will pose a threat to the crew, this article aims to conduct a safety assessment. According to the test, when the artillery firing indoor negative pressure dynamic process available under
