【摘要】 再生式液体火炮的内弹道循环中存在液体燃料喷射、破碎和雾化过程,这给内弹道问题带来极大的复杂性。本文用经验关系给出雾化后的液滴直径及其燃烧规律,根据绝热压缩建立液相的状态方程,喷射过程采用非稳态的伯努里方程。在某些假设条件下建立起一组封闭的内弹道方程系。用美国120mm再生式液体火炮的参数进行数值求解,获得稳定的计算结果。更多还原

【Abstract】 In the interior ballistic cycle of a Regenerative Liquid Propellant Gun there exist some special phenomena such as jet formation and breaking, atomization of the liquid propellant etc. making the interior ballistic problem very complex. This paper approximates the drop size and law of burning of the liquid propellant using the classical interior ballistic relationships, the state equation of the liquid phase using the isothermal compression relationship and the jet process using the non-stationary Bernoulli equation. A closed set of the interior ballistic equations is established under some assumptions. Stable results of the interior ballistic computation were obtained with the help of the structural parameters of the USA 120mm Regenerative Liquid-Propellant Gun.更多还原
