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

CTOnews.com, September 6, according to news from official account of Xinghe Power Aerospace, on September 5, Xinghe Power Aerospace launched a Ceres-1 sea-launched carrier rocket from Haiyang and nearby waters in Shandong Province, sending 21-24 stars of the Apocalypse constellation into a scheduled orbit 800km high. This was the first sea launch mission carried out by a private rocket company in China, and the launch was successful.

▲ Tuyuan Xinghe Power official account CTOnews.com learned after inquiry that the mission, code-named "Little Mermaid" (The Little Mermaid), was organized and directed by the sea launch team of Taiyuan Satellite launch Center, and it was also the ninth flight of the Ceres-1 carrier rocket.

In addition, the mission carries the Apocalypse constellation 21-24, which is a low-orbit data acquisition satellite developed by Beijing Guodian Hi-Tech and is part of the "Apocalypse" project. The project mainly "provides global and quasi-real-time Leo satellite Internet of things data services" and plans to complete deployment and operation in 2024.

It is reported that the satellite launched at sea has the characteristics of strong flexibility, good mission adaptability, and excellent launch economy, and can flexibly select launch sites and landing areas to meet the launch needs of various orbital payloads, and effectively solve the long-standing problem of the safety of debris landing areas. however, due to the high technical difficulty of launching satellites at sea, only a few countries in the world have mastered it.

Xinghe Power claims that it has made six breakthroughs so far:

1. Domestic private rocket launched at sea for the first time

2. Launch of the world's first unsupported land and sea general mobile platform

3. The world's first unguided thermal launch of a solid rocket at sea

4. Domestic commercial aerospace has entered the 800 km inclined orbit for the first time

5. for the first time in the world, the rocket adopts high-precision navigation scheme of sea vertical self-alignment and on-line misalignment angle correction.

6. the world's first solid rocket uses a non-pyrotechnic locking and release mechanism.

In terms of technology, Xinghe Power claims that the Ceres series rockets have implemented as many as 16 technological innovations:

1. Rocket Last stage structure / Power / Electrical Integration Technology

2. High-precision navigation technology of vertical self-alignment and on-line misadjustment angle correction on marine moving base.

3. The simple control technology of the first class non-rolling control device.

4. Modular multi-satellite separation timing design technology.

5. Simple and safe separation technology of launch vehicle fairing based on single spring.

6. rapid, safe and active derailment technology for the last stage of the rocket.

7. Accurate prediction technique of parameter orthogonalization 3D mode.

8. High integration / low cost / integrated electrical system technology

9. Low-cost space-based S-band high bit rate telemetry technology

10. the design and forming technology of the final integrated support of lightweight multi-function special-shaped composite material.

11. Distributed attitude control power system technology of pressure separation rail.

12. All-metal 3D printing track control engine technology

13. Design technology of multi-function miniaturized rail attitude control valve

14. Low-cost and unsupported land and sea general transshipment launch vehicle technology

15. Non-pyrotechnic locking and release technology of solid rocket

16. Unguided thermal launch technology of solid rocket at sea

In addition, in view of the launch environment of the moving base under the condition of sloshing at sea, it is reported that Ceres-1 sea-launched rocket used unguided thermal launch for the first time.

Compared with the guided launch methods such as barrel ejection and launcher, the Ceres-1 sea launch rocket continues to use the land transfer launch vehicle for thermal launch, which is fixed after the launch vehicle is on board, and only a magnesium belt locking mechanism is added at the rear end of the rocket, which is simple in structure and convenient to operate. the requirements for ground support conditions are low.

Xinghe Power said that in the future, the number of sea launches of Ceres-1 rocket will gradually increase, going hand in hand with the frequency of land launches.
