【摘要】 SDA 是利用高温高压气体作为动力源的机构,因此 SDA 的动力腔压力是影响安全设计的一个主要因素,所以对SDA 的动力腔平均压力的研究是很有必要的。本文首先推导了数学模型,然后用计算机进行了仿真,这些结果在实际应用中具有一定的价值。更多还原

【Abstract】 The SDA uses high temperature and high pressure gas as a source of power,the pressure in kinetic chamber of SDA is a major factor in safe design,so the research on pressure in kinetic chamber is very important.The article deduce mathematical model at first,then simulate it by computer and the results will be valuable in application更多还原
