CZ-2Dsoared up into the sky with full scores
CZ-2D was launched at Jiuquan Satellite Launch Centre on July 5, 2020, succeeding in sending Test 6-02 Satellite into the preset orbit.
As a two-stage common-temperature liquid carrier rocket developed by Shanghai Academy of Spaceflight Technology, the launched CZ-2D is characterized by about 300t takeoff thrust, 1.2t carrying capacity corresponding to 700km solar synchronous orbit, and the capacity to launch single/multiple satellites as requested by different orbits.
The launched CZ-2Dis further improved on the basis of the double strap-down control system, and the single-point quantity of electrical system is decreased by 22% through updating redundancy products and single machine, to strengthen rocket reliability. Meanwhile, the rocket timing control system is also improved, and tasks are switched uniformly under a fixed state, to better realize the serial connection and parallel connection of the model with multiple satellites, and improve the capacity to complete tasks.
The confirmation system of launching site was firstly implemented in the launchedCZ-2D, while quality confirmation was carried out before and during the filling in replacement of the original report of conditions in all phases as well as the final review on quality control conditions before filling. By illustrating in the form of charting, the conformation system of launching site provided more than 60 record tables and 30 quality confirmation tables covering all positions at the launching site from product unloading, transfer docking, and the execution of compulsory checkpoints to the filling. All systems and positions were managed by special personnel, who would be in charge of confirming and implementing work by items based on the quality conformation table, normalizing the operating process, and recording valuable original data. As the quality confirmation system is implemented at the launching site, both the efficiency and effectiveness of quality control can be further improved, so it’s regarded as a major approach to boost upgraded modes of scientific research on aerospace and production management, and ensure that the requirements for high quality, high efficiency and high benefits can be well implemented.
The launched Test 6-02 Satellite is developed by Shanghai Engineering Center for Microsatellites (SECM), and is mainly used to detect space environment and carry out relevant technical tests.
This is the 49th launch of CZ-2D, the 118th flying experience of Long March series of carrier rockets developed by Shanghai Academy of Spaceflight Technology, and also the 338th launch of Long March series of carrier rockets.
