硬质泡沫喷管堵盖试验及研究

Test and research of nozzle closure made of hard foamed plastics

介绍了固体火箭发动机喷管硬质泡沫塑料堵盖的设计方法与试验过程。某型号发动机硬质泡沫喷管堵盖打开压强模拟点火试验结果表明,这种硬质泡沫喷管堵盖设计方案可行,并已在实际中得到应用。

Design methods and test process of nozzle closure made of hard foamed plastics for SRM were introduced. The pressure for opening the nozzle closure was determined in the simulated ignition test. The results show that the design scheme is reasonable. This kind of closure has been used in the practice.
