en.Wedoany.com Reported - The first Long March 12B carrier rocket lifted off from the Dongfeng Commercial Aerospace Innovation Demonstration Zone, marking a complete success in its maiden flight. This is a domestic single-core commercial rocket with a 20-ton payload capacity, utilizing a full liquid oxygen kerosene propulsion scheme and featuring a reusable first-stage design. It was developed in just 21 months, focusing on low cost and high-density commercial launches, primarily serving the construction of the Qianfan low-orbit mega-constellation network.
Loongson officially announced that, as the "central brain" of the carrier rocket, the core control system of the Long March 12B is equipped with a Loongson high-reliability processor. With its excellent product performance and strong adaptability to harsh environments, the processor delivers stable computing power under complex flight conditions. This marks the first application of a Loongson processor in the core control system of a Long March series carrier rocket.
The core control system of a carrier rocket runs throughout the entire flight cycle, including liftoff, ascent, trajectory correction, and precise orbital insertion, serving as the central hub ensuring precise and controllable mission execution. During high-speed orbital flight, the rocket must continuously withstand extreme environments such as drastic temperature changes at high altitudes, complex airflow disturbances, and strong electromagnetic interference, imposing extremely high demands on the real-time computing speed, operational stability, and anti-interference capability of the control system. As the core computing carrier of the control system, the processor is a critical component determining the success or failure of a launch mission.
In this mission, the Long March 12B adopted the Loongson processor, independently reconstructing core interaction logic and scheduling algorithms, successfully bridging the technical gap between the underlying protocol stack and upper-layer applications. This fully validates the leading technical architecture, exceptional environmental adaptability, and high operational reliability of the Loongson processor, conclusively proving that it fully meets the stringent standards for routine constellation launches of commercial carrier rockets.
