Beijing Zhongke Aerospace Exploration Technology Co., Ltd. is the first domestic aerospace enterprise with mixed ownership, and it is also the target enterprise that Oriental Aerospace Port focuses on introducing. Relying on the scientific research strength and resource advantages of the Institute of Mechanics of the Chinese Academy of Sciences and the Aerospace Flight Technology Center of the Chinese Academy of Sciences, China Aerospace Science and Technology has been committed to the research and development and integration of space technology and aerospace vehicles as a platform for the transformation of major national scientific research projects, as well as the transformation and provision of technological achievements. Aerospace launch service. The Lijian-1 rocket project also adds a brand-new name card to the Oriental Space Port, which will surely promote the construction of the Oriental Space Port to take a solid step forward.
The Zhongke Aerospace rocket type spectrum
🔷Lijian No. 1 is China’s current largest solid launch vehicle, with a take-off weight of 135 tons, a take-off thrust of 200 tons, a total length of 30 meters, a core diameter of 2.65 meters, and a 500-kilometer sun-synchronous orbit carrying capacity of 1,500 kilograms. On July 27, 2022, the first flight mission of the Lijian-1 launch vehicle was a complete success. It broke through 6 major key technologies and 13 technologies that were used for the first time in China, enriching the pedigree of my country’s solid launch vehicle launch capabilities and setting the stage for my country’s launch vehicle field. made important contributions to technological changes.
🔷Lijian 2 is a medium-sized liquid launch vehicle independently developed by China Aerospace Science and Technology Corporation. It inherits the excellent genes and advanced technology of “Lijian 1”. Lijian 2 liquid launch vehicle adopts CBC configuration, with a universal core diameter of 3.35 meters, with a total length of 53 meters, a take-off mass of 628 tons, and a take-off thrust of 766 tons. SSO has a carrying capacity of 7.8 tons, and LEO has a carrying capacity of 12 tons. It has the ability to launch into sun-synchronous orbit, low-Earth orbit, and transfer orbit. It will become my country’s low-cost cargo spacecraft and satellite Internet group with large transportation capacity, high reliability, low cost, and excellent service. It is the main rocket for launching Internet and space science satellites, as well as deep space exploration missions.
🔷Lijian-3 is a reusable medium-sized launch vehicle. Both the first and second stages use 80-ton reusable liquid oxygen/kerosene engines. It has the ability to recover and reuse, and is aimed at low-cost launches for low-orbit constellations and large-scale space facilities. Demand; the Lijian-3 heavy-lift launch vehicle adopts a reusable universal core stage configuration. Both the core stage and booster can be recycled and reused, which can meet the needs of large-scale launches in low-Earth orbit. It is equipped with a high-performance liquid upper stage to improve geosynchronous orbit. , lunar transfer orbit and other high-orbit launch mission adaptability.
🔷The space tourism vehicle uses a combination of a single-stage rocket and a space capsule. The rocket has a diameter of 3.35 meters and is equipped with five 15t-level liquid oxygen and kerosene engines, with a take-off thrust of 75t and a take-off mass of 70t. The space capsule has a diameter of 3.35 meters, a height of 3 meters, and 4 fans. It has panoramic windows and can accommodate 7 passengers on a single flight. The landing site for aircraft launch and recovery will be planned and constructed in coordination with the aerospace theme park, space experience hall and aerospace science education base, where passengers will receive short-term training before flying. Passengers will cross the Kármán Line and experience the feeling of weightlessness that escapes the Earth’s gravity. Finally, the space capsule landed safely via parachute, and the passengers returned to Earth safely.
