Thanks to CTOnews.com netizen ZKSen for the clue delivery! CTOnews.com, July 25 (Xinhua)-- Xinghe Power Aerospace Company (hereinafter referred to as "Xinghe Power") officially announced that it has made phased progress in the preliminary test and verification of the vertical recovery control technology at the end of the rocket based on the scale platform.

Tuyuan Xinghe Power official account according to the official introduction of Xinghe Power, in this verification, the company completed the tracking and landing test of the pre-installed optimal landing trajectory, verified that the platform was in a stable state during flight, and that the tracking trajectory deviation, landing point deviation, attitude deviation and other indicators all met the design requirements, and achieved the purpose of the test. In the future, the on-line trajectory planning landing experiment based on convex optimization will be carried out to verify the vertical recovery landing control algorithm.

Tuyuan Xinghe Power official account CTOnews.com learned from Xinghe Power official account that the scaling verification platform, named "Firebird one", is the scaled verification platform (aeronautical power) for the vertical recovery control technology of the Zhisheng-1 carrier rocket, and is mainly used to verify the navigation, guidance, and control technologies and algorithms related to the vertical recovery terminal of the rocket, and to provide technical exploration and support for the future development of corresponding products.

The Firebird recovery technology verification platform planned by Xinghe Power Company includes Firebird 1 scale verification platform based on aviation power and Firebird 6 full-size verification platform based on self-developed liquid oxygen kerosene rocket engine.

Zhi Shenxing 1 carrier rocket, Tuyuan Xinghe Power official account "Zhi Shenxing 1" is a medium-and large-scale reused liquid carrier rocket independently developed by Xinghe Power and Aerospace Company. it is the first commercial carrier rocket in China to adopt 7-machine circumferential parallel recovery configuration. mainly for the market demand of large constellation network, it can provide low-orbit capacity of not less than 5 tons, and the expanded bundled configuration can reach 14 tons. The design was reused for 50 times.

In addition, "Zhi Shenxing 1" adopts a central unit, six sets uniformly distributed in the circumferential direction, and a full two-way swing scheme, combined with the depth conversion capability of the CQ-50 liquid oxygen kerosene engine developed by the company (35%-110%). It is said that "it can not only meet the requirements of vertical recovery and reuse, but also has the ability of power redundancy, that is, the ability of the other six engines to ensure normal flight into orbit in the event of any engine failure."
