Jiuquan, June 17 - The Kuaizhou-11 Y13 carrier rocket lifted off from the Jiuquan Satellite Launch Center and delivered its satellite payload into the pre-planned orbit. This marks another successful space mission for the Kuaizhou-11 rocket, coming just three months after its previous launch in March. Baowu Carbon Baojing Composites, the core developer of the rocket's first-stage composite engine combustion chamber casing, provided critical technical backing for the mission.

The Kuaizhou-11 rocket adopts carbon fiber composites for its primary structural components. Its first-stage engine combustion chamber casing measures over 2 meters in diameter and more than 10 meters in length, imposing stringent requirements on load-bearing performance and structural lightweighting. Drawing on its technical expertise in integrated forming of large composite casings and lightweight high-strength structural design, Baojing Composites underpins the rocket's rapid-response launch capability and reliable orbital insertion.

Since its maiden flight in 2020, the Kuaizhou-11 has completed six launches, steadily validating its reliability and fast-response characteristics as a commercial solid-fuel carrier rocket. The manufacturing technology and integrated process solution for the first-stage composite combustion chamber casing developed by Baojing Composites have passed multiple flight verifications. Its strengths in weight reduction, efficiency gains and high-strength monolithic forming have been fully demonstrated in real missions, accumulating valuable engineering experience for the application of large-scale composite structures on China's solid carrier rockets.
