此项实验研究在于了解多次点火对固体燃料冲压发动机燃烧效率和燃料性能的影响，研究对象分别为纯ＨＴＰＢ固体燃料和金属化Ｂ４Ｃ／ＨＴＰＢ固体燃料。试验中采用差分扫描量热法分析了对燃料性能的影响。其中燃料药柱的热性能和机械性能没受到影响，燃烧效率略有增加。
The experimental study is to understand the impact of multiple ignition on the combustion efficiency and fuel performance of solid fuel ramjet engine. The subjects are pure HTPB solid fuel and metallized B4C / HTPB solid fuel, respectively. Differential scanning calorimetry was used to analyze the effect on fuel performance. The thermal and mechanical properties of the fuel pellets were not affected and the combustion efficiency increased slightly.
