On December 7, 2022, the China Fast Boat 11 solid carrier rocket ignited and launched at Jiuquan Satellite Launch Center, successfully putting related satellites into the scheduled orbit, and the launch mission was a complete success.
The high-performance composite combustion chamber of the third stage rocket engine is designed and produced by JSXY Advanced Materials Technology Group.
Combustion chamber is the core component of rocket engine
Previously, the combustion chamber of solid rocket motor was usually made of metal alloy materials, and the shell was very heavy.
Once it is too heavy, it will affect the carrying capacity of the rocket.
JSXY has been developing high-performance carbon fiber composites for China's aerospace industry since 2015.
It took seven years to launch the rocket engine composite combustion chamber, which can withstand the ablation erosion of the engine combustion chamber at 3000 ℃ high temperature and pressure.
