摘　　要：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HfO_2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 com- posite 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 com- posite 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.
