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.
Zhongke Aerospace successfully completed the vertical recovery flight test at sea From January to March, Zhongke Aerospace continued to conduct vertical recovery demonstration and verification flight tests in Haiyang, Shandong, and successively carried out land launch recovery and sea recovery.
The vertical recovery principle prototype of Zhongke Aerospace launch vehicle, which successfully completed the flight test this time, is used as a technology verification platform. At the beginning of the scheme design, it has adhered to the innovative design concept and adopted the integrated control system of power supply and distribution-control-telemetry Design and 3D printing design and process the anti-sway storage tank, and adopt a lightweight carbon fibre structure to realize the integrated configuration of bearing-force transmission-vibration suppression, which can integrate and reuse the functions of multiple systems, greatly simplifying the overall quality Connected with cables, it can be applied in similar miniaturized aircraft.
The complete success of the demonstration test of the vertical recovery principle prototype of the Zhongke Aerospace Launch Vehicle at sea has verified a number of key technologies. The success of the flight test will carry out technical research and accumulation for the near-space recyclable scientific experiment platform, the sub-stage recovery of the orbiting rocket, and the space tourism vehicle, which will be applied in subsequent models and sub-stage recovery missions of the orbiting rocket.
The whole flight test simulates and verifies the flight process of launch on land and recovery at sea, mainly to verify the process of landing at sea during the recovery process of the sub-stage rocket into orbit, and the communication and relative measurement technology under the influence of sea clutter environment. The landing accuracy of the Kilometer-level flight environment and the shaking of the offshore landing platform will be assessed. The maximum flight altitude is greater than 1000m. After flying to the highest point, adjust the attitude and descend after hovering. The descending section is decelerated by the reverse thrust of the engine, so that the speed of the aircraft can be reduced below 2m/s when approaching the landing platform at sea, and then through the buffer legs Realize soft landing, the whole flight takes about 10 minutes, and the landing point accuracy is better than 10m.
In terms of vertical return high-precision guidance and control technology, the re-entry and return high-precision navigation and positioning technology, the powered vertical recovery online trajectory generation guidance technology for the prototype of the carrying principle, the adaptive flight control technology for complex environments, and the initial alignment of offshore shaking platforms And long-term tracking technology, the verification work of semi-physical verification technology for the whole flight…
