[China’s first 10-kilometer-class vertical take-off and landing flight test of a reusable carrier rocket was a complete success]

On June 23rd 2024, China’s first 10-kilometer-class vertical take-off and landing flight test of a reusable carrier rocket was a complete success. The rocket was developed by the Eighth Academy of China Aerospace Science and Technology Corporation.

 At about 1300 hours Beijing Time, at the Jiuquan Satellite Launch Center, Inner Mongolia, China, People’s Republic of China , a 3.8-meter-diameter reusable carrier rocket new technology verification arrow was erected on the launch pad. Three variable thrust liquid oxygen-methane engines were ignited, spewing blue tail flames. The rocket body rose to an altitude of about 12 kilometers. The central engine adjusted the thrust, and the rocket descended in a controlled manner. At 50 meters from the ground, the four landing legs unfolded, and then the rocket slowly descended, approaching zero altitude, and landed steadily on the recovery field, achieving a fixed-point vertical soft landing.


This test is currently the largest-scale vertical take-off and landing flight test of a reusable carrier rocket in China, and it is also the first application of the domestically developed deep variable thrust liquid oxygen-methane engine in a 10-kilometer-class return flight.
The entire test took about 6 minutes. The rocket went through five stages: accelerated ascent, decelerated ascent, accelerated descent, decelerated descent, and slow descent, achieving “take-off, accurate control, unfolding, and stable landing”.

[Take off, control accurately, deploy, and land steadily! China’s first 10-kilometer-level vertical take-off and landing flight test of a reusable carrier rocket was a complete success]

On the 14th June 2024  CNSA _China National Space Administration -China – People’s Republic of China at a China Academy Of Launch Vehicle Technology  Engine Testing complex.. On June 14, the Long March 10 series rockets used for manned lunar landing and other missions successfully completed the test of the first-stage rocket power system. During the test, the engine started normally, worked stably, shut down at a fixed time, and all parameters were tested normally. This test is the first system-level large-scale ground test of the Long March 10 series of launch vehicles. The matching of the first-stage booster delivery system and the engine, the propellant filling process, the multi-machine parallel power transmission and environmental characteristics and other technologies were fully verified.

The Long March 10 rocket is a three-and-a-half-stage rocket developed for the manned lunar exploration project. The total length of the rocket is 92.5 meters, the takeoff weight is about 2,189 tons, the takeoff thrust is about 2,678 tons, and the Earth-Moon transfer orbit carrying capacity is not less than 27 tons. In the future, it will be used to launch a new generation of manned spacecraft and lunar landers. In addition, the Long March 10 has also designed another booster-free configuration that can perform space station astronaut and cargo transportation tasks….

The engine is the power source of the rocket, and its development process is very complicated. Test run is an important link in the engine development process, and there are dozens of types. In layman’s terms, engine test run is the process of igniting the engine and verifying the rationality of its design scheme and process reliability. This is an indispensable and important part of the development and delivery of a type 1 engine. It will run through all stages before and after engine development. Each stage of test run has different meanings, and the ignition time varies from a few seconds to hundreds of seconds.

It is reported that the engine used in this test run uses advanced liquid oxygen kerosene as fuel, which is improved and iterated from the high-thrust liquid oxygen kerosene engine used by the new generation of launch vehicles such as the Long March 5. The thrust reaches 130 tons. The R&D team of the Sixth Academy of Aerospace Science and Technology Group adheres to the concept of digital design, and has successively overcome key technical problems such as engine start-up and shutdown sequence, engine wide-range continuously variable thrust, and engine long life and high reliability.

In addition, the continuous success of the test run has fully verified the reliability of a number of new carrying process technologies. The engine production of this test run adopts the concept of intelligent manufacturing, and actively applies new materials, new processes, and new technologies. The inner wall of the thrust chamber of the core component adopts a new protective coating, key assemblies adopt automatic welding technology, and a large number of components adopt 3D printing technology.

During the preparation of the engine test run, the participants in the research and test conducted tests and verifications on each subsystem of the test through comprehensive means such as digital modelling, simulation calculation, and system debugging. The successful test run shows that the test area has greatly improved the multi-station parallel test run capability and test efficiency by optimizing the workflow.
