一、引言近期,对点火过程进行了广泛的研究。为了这些研究,提出了各种点火模型并在一般情况下进行了点火试验。通过试验结果的分析和比较,对复合及双基两种固体推进剂发动机的点火程序有了进一步的了解。例如采用聚酯过氯酸铵复合推进剂及硼/硝酸钾点火药,通过试验找出点火器和发动机的某些重要参数,如自由容积、推进剂的面积比以及装药重量等的
I. INTRODUCTION Recently, extensive research has been conducted on the ignition process. For these studies, various ignition models were proposed and ignition tests were conducted under normal circumstances. Through the analysis and comparison of the test results, the ignition procedures of the two solid propellant engines with composite and double bases are further understood. For example, the use of polyester ammonium perchlorate propellants and boron / potassium nitrate ignition powder, ignition and engine through the test to identify some of the important parameters, such as the free volume, propellant area ratio and the weight of the charge
