Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com, April 4, according to the official news of China Science and Technology Aerospace, the company continued to conduct vertical recovery demonstration flight tests in Haiyang, Shandong Province from January to March, and successively carried out land launch recovery and sea recovery. The demonstration test of the principle prototype of vertical recovery at sea of China Science and Technology Aerospace launch vehicle is a complete success, which verifies a number of key technologies.

It is said that in the aspect of vertical return high-precision guidance and control technology, they have completed the reentry high-precision navigation and positioning technology, the dynamic vertical recovery on-line trajectory generation guidance technology of the carrier prototype, the adaptive flight control technology in complex environment, the initial alignment and long-term tracking technology of the sea sloshing platform, and the verification of hardware-in-the-loop verification technology for the whole flight.

The whole flight test simulates and verifies the flight process of land launch and sea recovery, mainly verifies the process of sea landing in the process of sub-stage recovery of in-orbit rocket, communication and relative measurement technology under the influence of sea clutter environment. The landing accuracy of the mileage flight environment at the end of the recovery landing stage and the landing accuracy of the offshore landing platform under the sloshing condition are evaluated.

According to reports, the maximum flight altitude in the test is more than 1000m. After reaching the highest point of flight, the attitude is adjusted to decrease after hovering, and the descending section is decelerated by the reverse push of the engine, so that the speed of the aircraft can be reduced to less than 2m / s when approaching the offshore landing platform, and then the soft landing is realized by cushioning legs. As the title of CTOnews.com shows, the accuracy of the landing point in this experiment is better than 10m, and the whole flight lasts about 10 minutes.

Officials said that the success of this flight test will carry out technical research and accumulation for the near-space recyclable scientific experiment platform, sub-stage recovery of orbiting rockets, and space tourism vehicles, and will be applied in the sub-stage recovery missions of follow-up models and orbiting rockets.
