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.

At 12:00 on September 11, 2024 Beijing Time Jiuquan Satellite launch Center, Inner Mongolia, China, People’s Republic of China , the Suzaku-3 VTVL-1 reusable vertical take-off and landing recovery test rocket independently developed by Blue Arrow Space Technology Co., Ltd. successfully completed a ten-kilometer-level vertical take-off and landing return flight test at the Blue Arrow liquid oxygen and methane rocket launch station at the Jiuquan Satellite Launch Center in China .This mission is the first time in China to achieve secondary ignition of a vertical take-off and landing return rocket in the air, joint guidance and control of the “grid rudder-cold air attitude control-engine” in a transonic high dynamic pressure environment, and engineering application of real-time wind repair technology for high-altitude winds. It marks a major breakthrough in China’s commercial aerospace industry in reusable launch vehicle technology, and is a crucial step towards the realization of large-capacity, low-cost, high-frequency, reusable space launches in the future!
In this test, the total air flight time of the Suzaku-3 VTVL-1 test rocket was 200.7s, and it went through the process of “ascent – engine shutdown – unpowered gliding – engine secondary start in the air – soft landing”. Among them, the engine was shut down for the first time about 113 seconds after takeoff. After shutdown, the rocket continued to rely on inertia to fly to the highest point of 10002m above the ground. In order to offset the high-altitude crosswind interference of 36m/s, the rocket relied on high-altitude wind correction, grid rudder and cold air attitude control to stabilize the flight attitude; after about 40s of unpowered gliding, when the rocket altitude dropped to 4.64km and the speed reached 0.8Ma, the engine was ignited again in the air at 100% working conditions, and the rocket entered the landing deceleration section, and through the online guidance control algorithm, the engine thrust and flight state were adjusted to guide the rocket body to achieve a soft landing on the recovery field about 3.2km away from the launch station; the center of the landing position was 1.7m away from the center of the recovery field, the landing vertical speed was -1.65m/s, and the landing attitude angle deviation was 0.3°. All indicators met the expected design and reached the domestic leading level.
This mission is an advanced verification of various key technologies for vertical take-off, landing and recovery of large liquid oxygen-methane reusable rockets, following the successful execution of the 100-meter-class flight test mission in January 2024. The test rocket is a single-stage liquid oxygen-methane rocket with a body diameter of 3.35m, a length of 18.3m, a take-off mass of approximately 68t, a take-off thrust of 800 kilonewtons, and is equipped with 3 sets of landing cushion legs and a new 4-piece grid rudder system. It uses a high-strength stainless steel body structure consistent with the Suzaku-3 rocket; it is equipped with an 80-ton Tianque-12 (TQ-12) improved liquid oxygen-methane engine of the same type as the Suzaku-3 rocket, which has achieved continuous orbital flight verification, and has orthogonal double pendulum, 45%~111% variable thrust adjustment and multiple ignition capabilities. The verification results achieved in this mission are as follows:
The Suzaku-3 VTVL-1 test rocket is an engineering prototype built with a full-size engine, and is an important part of the development of the Blue Arrow Aerospace reusable rocket project. This test strictly followed the company’s quality management system and test safety management requirements , carried out comprehensive risk identification and control , organized special review and recalculation and process review , and formulated and improved mission operating procedures and emergency response plans to ensure the success of the test. Through two vertical take-off and landing recovery tests, the model team successfully verified a number of key technologies for reusable rockets, laying a solid foundation for the future first flight and recovery of the Suzaku-3.
Since October 2022, Blue Arrow Aerospace has been fully committed to promoting the demonstration and development of large liquid oxygen and methane reusable rockets, and has clarified the development route of the next-generation reusable rocket Suzaku-3. At the beginning of this year, Suzaku-3 has completed the transition from the scheme stage to the prototype stage, and has fully carried out the development of various system products in the prototype stage. It is planned to carry out its first flight in 2025 and realize the recovery and reuse of the first stage in 2026, striving to help China’s commercial aerospace achieve a fundamental breakthrough in large-capacity, low-cost, and reusable launch vehicle technology in the next three years!
