BEIJING, March 3 (Xinhua) -- Smart Dragon-3 (SD-3), the third member of China's Dragon series commercial carrier rockets family, will make its maiden flight in 2022, its developer said Wednesday.

A four-stage solid-propellant rocket, the SD-3 will be the largest and have the highest carrying capacity among the Dragon series, according to the China Academy of Launch Vehicle Technology.

With a maximum diameter of 2.64 meters and a takeoff weight of 140 tonnes, the rocket is capable of sending a payload of 1.5 tonnes to the solar synchronous orbit at an altitude of 500 km.

To meet the large-scale commercial launch demands, the rocket's multi-satellite launch capability enables it to carry more than 20 satellites in a single mission, while the cost is just 10,000 U.S. dollars per kg, making it competitive in the market.

The rocket maker said the SD-3 was designed for both land and sea launches.

[Jielong 3 rocket fully transferred to the engineering development stage]

The Jielong-3 solid carrier rocket (code-named "SD-3") has recently been fully transferred to the engineering development stage. "Jielong 3" is the largest solid carrier rocket in China. It has a multi-satellite launch capability of "20 satellite per launch" and can be launched on the turbulent sea. It supports the remote security control technology of a general-purpose notebook and truly realizes a computer "One-click launch"!

You really dont want to fly from the Eastern Hemisphere to the Western one in just 2 hours on one of these if you are not a trained pilot.

[The first half-system test of the heavy-duty carrier rocket 220-ton staged combustion cycle hydrogen-oxygen engine was successfully completed]

September 23, the heavy-duty carrier rocket 220-ton staged cycle hydrogen-oxygen engine developed by China Aerospace Science and Technology Corporation successfully carried out the first half-system test , The test was a complete success.

The main purpose of this test is to obtain the coordinated working characteristics of the core components of the staged combustion cycle hydrogen-oxygen engine. The test starts and shuts down normally according to the predetermined procedure, the engine start process is fast, the main stage is stable and normal, and the parameters reach the expected values. The test has fully achieved the expected purpose, and the test parameters are the highest level in the history of the development of hydrogen-oxygen engines in my country.

This test is based on the comprehensive completion of the deep development work of the 220-ton staged combustion cycle hydrogen-oxygen engine, a key test arranged for the engine before the test run. The engine except for the thrust chamber and the pre-pressurized turbo pump, all core components have participated in the test assessment, verifying the correctness of the design, manufacture and test plan of the high-thrust supplementary combustion cycle oxyhydrogen engine.

The complete success of this test indicates that my country has achieved another milestone and important breakthrough in the key technology of the 220-ton staged combustion cycle hydrogen-oxygen engine, laying a solid foundation for the subsequent hot test of the full-system engine.
