本文对采用高温燃气配合冷却水连续注入式调能的水下导弹弹射过程进行分析,考虑了火药燃烧产物中水蒸气的影响,将燃气中的水与冷却水统一考虑,再分为预先集中注入水和连续喷注水两部分。针对燃烧产物及不同阶段注入的水,进行了汽化机理、建压、做功过程分析,并以此为基础,依据弹射进程的不同特点,按3个不同的特征阶段,建立了能量平衡方程和汽化方程,构建了考虑火药燃烧产物中水蒸气的弹射弹道模型基本方程组,该模型的改进提高了水下导弹弹射出筒过程的计算精度。
In the present study, the underwater missile launch process with high temperature gas and continue cooling water injection method was studied. The effect of the water vapor in the gas and cooling injection were taken into consideration together, and the difference between the pre-injection and continue injection is analyzed. Based on the process analysis of the phase change, pressure building and performance for the combustion production and water from different stage, the gasification and energy balance equation are developed for three stages, and ejection model equations considering the water vapor from the combustion gas was proposed. The improvement of the ejection model improves the calculation accuracy of the underwater launch process.
