On the 7th January 2025 schedule to launch  CNSA _China National Space Administration -China – People’s Republic of China 0400 Hours Hong Kong –Beijing Time China- People’s Republic of China…. at the Xichang Satellite Launch Center, Sichuan Province of the Xichang Launch Center, the Long March 3B carrier rocket was launched, sending This morning, China successfully launched the Shijian 25 satellite into space using the Long March 3B carrier rocket at the Xichang Satellite Launch Center. The satellite entered the planned orbit smoothly and the launch mission was a complete success. The satellite is mainly used for satellite fuel replenishment and life extension service technology verification..

At 04:00 on January 7, the Long March 3B carrier rocket ignited and took off from the Xichang Satellite Launch Center, and then sent the Practice 25 satellite into its predetermined orbit. This marked a “good start” for China’s space launch mission in 2025.

The Long March 3B rocket, Long March 3A rocket and Long March 3C rocket together constitute the Long March 3A series of rockets, which are developed by the First Academy of China Aerospace Science and Technology Corporation. The Practice 25 satellite is developed by the Eighth Academy of China Aerospace Science and Technology Corporation.

This year, the Long March 3A series of rockets are expected to carry out more than 10 launch missions. The rocket team will continue to improve the rocket’s mission adaptability by promoting de-missionized batch production, cross-parallel working mode, and tightening quality control.

Since August last year, the First Academy has tried to use a professional test and launch team to participate in the Long March 3 series of launch missions, promoting the transformation of the rocket test and launch model from a scientific research model to a professional model, thereby optimizing personnel allocation and freeing up the designer team. After nearly half a year of internship training, 9 positions in the first phase of this launch mission have been taken over, and the optimization of the professional test and launch model will continue to be promoted in the future.

The Shijian No. 25 refueling service aircraft was developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It is used for satellite fuel replenishment and life extension services, and provides sufficient energy guarantee for the long-term operation of satellites in orbit. It can carry 1.3 tons of fuel at a time, accounting for 52% of its own weight.


When the refueling service aircraft receives a distress signal from a fuel-shortage satellite, it will, under the guidance of the ground dispatch system and with the help of its front-end navigation system, achieve “automatic driving and door-to-door service.” After arriving near the satellite, the aircraft uses the navigation system to autonomously track and approach the satellite. When the aircraft is within about 2 meters of the satellite, it will cooperate with the robotic arm to achieve precise docking with the satellite’s fuel refueling port, establish a fuel transfer path, and smoothly carry out “space refueling.

During the mission, the launch site test team of China Aerospace Science and Technology Corporation adhered to the guidance of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, fully implemented the spirit of the 20th National Congress of the Communist Party of China and the Second and Third Plenary Sessions of the 20th Central Committee of the Communist Party of China, and implemented the spirit of the Ninth Working Conference of the Group Corporation. At the same time, it gave full play to the political function of the party organization, guided the test team members to improve their political stance, bear in mind their mission and responsibilities, and made every effort to ensure the complete success of the launch mission.

This launch is the 555th launch of the Long March series of launch vehicles.

#CNSA #ChinaNationalSpaceAdministration #国家航天局 |#BRI September2024 | #Tongchuan #ShaanxiProvince – Asia’s largest #CarrierRocket space engine high-altitude simulation test international benchmark for China’s Lunar Manned Lunar Mission..

DURING MAY 2024  CNSA _China National Space Administration – Assisting manned lunar landing Recently, Asia’s largest Carrier Rocket space engine high-altitude simulation test International benchmark  was completed and put into use in Tongchuan, Shaanxi province, China, People’s Republic of China, marking a major breakthrough in the key technology of high-altitude simulation test of the main reduction engine of China’s manned lunar landing project, which will effectively guarantee and support the smooth implementation of the manned lunar exploration project. What is a space engine test bench? Why is it the “ultimate test site” for Carrier Rocket spacecraft engines?

1. What is a space engine test bench?

There is a consensus in the aerospace field: “To develop aerospace, power comes first .” In space exploration, space engines provide power for launch vehicles and other spacecraft to fly into space. If the engine is regarded as the “heart” of the rocket, then the space engine test bench is like the monitor of the rocket’s “heart”. It is a ground test facility specially used to test the performance of rocket engines . It is usually composed of a test workshop, a load-bearing pier, a guide trough, a measurement and control center, a measurement and control system, a test frame, etc. It can simulate the working environment of the engine to verify and evaluate the performance, function, strength, reliability and other aspects of the rocket engine, and ensure that the engine can work stably and reliably in actual flight.

2. Why build a space engine test bench?

The development of space engines is a complex and delicate project, which requires not only a deep theoretical foundation and advanced computational simulation technology, but also actual ignition tests to verify the accuracy and reliability of the design. Therefore, in the process of engine development, the combination of theory and practice is indispensable. The engine test bench is equipped with various high-precision sensors, which are the “senses” of engine testing and can monitor the key parameters of the engine in real time during the ignition test. Through these precise measurements, researchers can intuitively observe the performance of the engine in actual work, so as to have a comprehensive and in-depth understanding of the engine’s performance. These test parameters not only provide researchers with various indicators of the engine’s working status, but also serve as an important basis for evaluating engine performance. By comparing the test results with the design expectations, researchers can find deficiencies in the design and make necessary improvements and optimizations to the engine.

3. Why do different engines require “tailor-made” test benches?

From the perspective of type , since each type of engine has its own unique design and performance parameters, it determines the specific environment and conditions required for testing. This means that one test bench cannot solve the “package” engine test work. Different types of test benches need to be built according to different types of engines to make the test environment and the actual working environment of the engine as consistent as possible. For this reason, test benches can also be classified. For example , according to the scale of the test bench , the test bench structure, the propellant tank capacity, and the measurement and control equipment, it can be divided into large test benches and small and medium-sized test benches; according to the type of engine propellant, it can be divided into liquid oxygen and liquid hydrogen engine test benches, liquid oxygen and kerosene engine test benches, and room temperature storable engine test benches; according to the length of the engine thrust test, it can be divided into two types of test benches: steady-state test and dynamic test. The former mainly tests the engine’s steady-state thrust and pressure performance indicators, and verifies the quality of engine design and manufacturing through long-term stable work, while the latter focuses on the study of the thrust and pressure rise transition process and the aftereffect impulse change characteristics of the descending stage; according to the installation posture during the engine test, it can be divided into horizontal test benches and vertical test benches. The horizontal test bench has a wide range of uses, and the change of engine mass during operation has little effect on thrust measurement, but at the same time, this test bench is less sensitive to lateral forces. Vertical test benches are divided into upright and inverted types.

From a safety perspective , the test bench must ensure safety during the test process. Different engines will generate different thrust and heat flow when ignited, so special guide grooves and cooling systems are needed to deal with it.

From a measurement perspective , in order to obtain accurate test data, the sensors and measurement equipment on the test bench need to match the specific parameters of the engine. For example, the thrust measurement system must be able to accurately measure thrust within a specific range.

From the perspective of the simulation environment , the test bench is designed to simulate various conditions that the engine may encounter in actual flight, including high-altitude simulation, vibration environment, etc. The flight conditions of different engines may be different, so a specific simulation environment is required.

From a cost-effectiveness perspective, designing and building dedicated test rigs for different engines can improve the efficiency and accuracy of testing, saving time and resources in the long run.

From the perspective of technological development , the advancement of space engine development technology will be accompanied by new testing requirements. The construction of a dedicated test bench can provide the necessary testing support for new engines.

4. Why has the high-altitude simulation test bench become a development trend?

When launching, the engines of spacecraft such as the upper stage of a launch vehicle are in a state of low pressure at an altitude of more than 80 kilometers, and their high-altitude performance is very different from that on the ground. Since the aerodynamic and thermal loads that affect the structural strength of the engine cannot be simulated when it is stationary on the ground, a high- altitude simulation test bench is needed to create high-altitude conditions . Usually, a low-pressure environment of 30-40 kilometers is formed by vacuuming to simulate high-altitude flight conditions. The high-altitude simulation test bench is mainly used to assess the nozzle structure and performance of the engine in a low-pressure and vacuum environment to ensure the reliability of high-altitude operation. Through high-altitude simulated hot tests , the safety of the test can be improved , faults can be discovered and eliminated in a timely manner , and key support can be provided for the development of advanced engines .

With the continuous construction and improvement of the space engine test bench, it will provide a more advanced and reliable platform for the development and testing of various types of spacecraft engines.
