Group 1 - The article highlights the successful completion of the "Weiguang No. 1" modal rocket at the Hebei assembly base, marking it as China's first carrier rocket to fully utilize carbon fiber composite materials [2] - The carbon fiber composite materials used in the rocket reduce weight by over 30% compared to traditional metal materials, while providing high strength and resistance to extreme environments [2] - The rocket features a first stage and upper stage configuration, with a diameter of 3.8 meters, a total length of approximately 60 meters, and a launch mass of 350 tons, achieving a payload ratio of 3.14% [2] Group 2 - The rocket's engine can be ignited more than 20 times, supporting upper stage re-ignition and ballistic gliding to enhance payload capacity, with typical orbital missions increasing capacity by 1 to 2 tons through 200 to 500 seconds of gliding [2] - The modal rocket, which simulates the full rocket's shape, can adjust its mass and center of gravity through added weight structures, facilitating key technology research and development for ground systems [2]
