| Abstract: | 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. |
