Traveling through time and space & Doing timey wimy stuff.

On  the 27th July 2022  the 中科宇航Zhongke Aerospace first flight of the Chinese Academy of Sciences Lijian-1 ZK 1A carrier rocket successfully flew for the first time At 12:12 Hours Afternoon Hong Kong SAR – Beijing Time ……the ZK-1A Lijian-1 carrier rocket successfully made its first flight at the Jiuquan Satellite Launch Center – Inner Mongolia – China – People’s Republic of China successfully launched the new space technology test satellite, orbital atmospheric density The six satellites of the detection test satellite, the low-orbit quantum key distribution test satellite, the electromagnetic assembly test double satellite and the Nanyue Science Star were sent into the predetermined orbit, and the launch mission was a complete success. The launch vehicle is a solid launch vehicle independently developed by the Chinese Academy of Sciences. The six satellites it carries are used for space exploration, atmospheric density detection and other related technical verification and test applications  is mainly used for scientific experiments, educational popularization and research activities such as soil moisture detection, sea surface wind field detection, and data transmission….

Introducing CG video of the first flight of the Chinese Academy of Sciences Lijian-1 ZK 1A carrier rocket! ….Lijian No. 1 is a four-stage solid launch vehicle, which is currently the solid rocket with the largest carrying capacity in China. The rocket has a take-off weight of 135 tons and a 700-kilometer sun-synchronous orbit carrying capacity of 1330 kg. The first flight mission will be a one-shot, six-satellite launch mission.

“The Lijian-1 rocket is a major deployment project of the Chinese Academy of Sciences. It is of great strategic significance for leading the development of my country’s carrier rocket technology and model changes, and catching up with the world’s aerospace powers.” Zhongke Aerospace Chairman Yang Yiqiang said in an interview. The main launch equipment of the Lijian-1 rocket started in Haiyang on August 6 last year. It has successively completed 14 core technology researches that have been adopted for the first time in China, and completed the program demonstration, program design and engineering development work, which is about to be in March 2022. Implementation of the first launch mission of “One carrier and Six Satellites”…..

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.

[Lijian-1 Yaoyi launch vehicle first flight documentary released! ] At 12:12 Hong Kong SAR Beijing Time on July 27, 2022, the “Lijian-1” (ZK-1A) carrier rocket adopted the “one arrow and six satellites” method at the Jiuquan Satellite Launch Center to successfully send six satellites into the predetermined orbit, The first flight mission was a complete success. “Lijian No. 1” adopts a four-stage solid engine tandem layout scheme, with a take-off weight of about 135t, a total length of about 30m, a maximum arrow body diameter of 2.65m, and a 500km sun synchronous orbit (SSO) with a maximum carrying capacity of 1500kg.


The development of Lijian-1 lasted 1303 days, 151 items and 761 ground tests were completed, 277,300 lines of code were written, 646 drawings were drawn, and more than 850 project documents were written. Breakthrough in the overall optimization design and test of large-tonnage solid vehicles, advanced power system and vector control, centralized-distributed modern aerospace electronics, low-cost rocket body structure and separation, intelligent flight control, large-tonnage solid rocket ground use and thermal launch 6 items The major key technologies have fully assessed and verified the interface matching between the various systems of the project, the rationality of various technical processes, the accuracy of the formulation of force/thermal environmental conditions, the environmental adaptability of the products on the rocket, and the correctness of the rocket technical scheme…
