备注

针对高能硝酸羟胺(HAN)发动机特点,联合国防科技大学与贵研铂业股份有限公司研发了新型C/SiC复合材料身部,并进行地面试验。试验结果表明, C/SiC复合材料身部结构完好,表面HfO2基环障涂层较完整,未出现显著开裂、剥落,涂层效果明显,保证了HAN单元发动机工作寿命。本研究为C/SiC身部在HAN单元发动机上工程化应用提供参考。

According to the characteristics of the high-energy Hydroxylammonium Nitrate(HAN)thruster,a novel carbon fiber reinforced silicon carbide composite(C/SiC)thruster chamber was developed and the ground hot fire test was carried out.The test result shows that the C/SiC composite chamber works well during the tests,the HfO2-based environmental barrier coating(EBC)on the chamber is intact,and there is no significant crack or spallation on it,which protects the composite against the corrosion of the combustion gases of the engine.This study provides a reference for the engineering application of C/SiC thruster chamber in HAN thruster.
