摘要
枪炮二次焰的形成与燃烧产物中还原性气体息息相关。采用最小自由能法理论计算了硝酸铵发射药燃气组成随硝酸铵的变化。气相色谱分析表明,随着硝酸铵的增加,还原性气体含量大幅下降;30毫米火炮炮口焰参数表明,炮口火焰强度降低了42.37%。因此,硝酸铵能有效抑制二次焰的形成。
The formation of secondary muzzle flash is closely related to reducing gases in combustion products. Minimum free energy method is adopted to calculate gas components with the increasing of AN.Gas chromatographic analysis reveals that the reducing gases percentage composition greatly decreases with the increasing of AN. Parameters of muzzle flash on 30mm gun indicate that intensity of gun muzzle flash reduces by 42.37%.Therefor,AN can effectively inhibit the secondary muzzle flash of gunnery.
