Recently, DeepBlue Aerospace’s “Thunder-R1” engine rocking test run was a complete success. This test run included sine wave swing, square wave position, frequency sweep and triangle wave swing tests, covering the control requirements for subsequent flight missions and verifying the engine Compatibility with servo system operation.
This test run achieved the following results:
1. Feasibility of the plan
The “Thunder-R1” engine adopts a pump backswing solution, which has a small weight in the swing part, greatly reduces the power demand on the servo mechanism, and improves the response characteristics of the small engine control loop; the pump backswing technology can achieve the same swing angle. Significantly reducing the swing envelope is a key technology to achieve a parallel layout of multiple rockets in a limited space. This test run verified the feasibility of this solution;
2 Reliability of flexible links
The maximum swing angle of the engine during the test was ±7°, which verified the reliability of the high-pressure swing hose;
3. Stability of electrical system
Through multiple complete machine tests of the “Thunder-R1” engine, the working stability and reliability of the engine’s electrical system have been fully verified.
This test run fully assessed the relevant performance indicators of the engine controller, servo system, battery, measurement system, ignition system and other parts to meet the overall requirements for the delivery of the rocket. In addition, the engine servo is the most important execution link of the rocket control system, and its working performance, stability and reliability were fully assessed and verified during this engine test run. The engine servo operates according to regulations and completes unidirectional swing and omnidirectional swing of various swing angles at multiple frequency points, with a maximum swing angle of 7 degrees. The engine servo is working normally and all performance indicators meet the requirements of the rocket control system.
This engine test has accumulated a large amount of data and valuable experience for the power system test. It also laid the foundation for the high-altitude VTVL recovery test of the first sub-stage of the “Nebula-1” rocket that Deep Blue Aerospace will conduct this year, as well as the first flight of the “Nebula-1” rocket. Solid foundation.

The “Thunder-R1” engine thrust vector control adopts a pump backswing technical solution. As the name suggests, a swingable high-pressure hose is set between the engine’s thrust chamber and the turbine pump. When the engine is performing vector control during operation, the turbine The pump is stationary and the thrust chamber is oscillated by the servo actuator. The name pump backswing engine actually comes from the perspective of the overall engine layout. This layout is based on the engine frame, and the frame and the thrust chamber are connected through a gimbal. Since only the thrust chamber swings, the swing mass and inertia are small, and the power requirements for the servo actuator are lower; since the turbopump does not swing, the engine swing profile is more compact, and the saved space provides the possibility to connect more rocket engines in parallel.
长征十号 At 22nd 23rd July 2023 Hong Kong SAR- Beijing time , China- People’s Republic of China- CNSA –China National Space Administration Successfully Carrier Rocket engine tested for the New Next Generation Chang Zheng – Long March 10 Manned Lunar mission landing Carrier rocket freighter The main engine of China’s manned lunar landing rocket Long March 10 completed another ignition test run yesterday, which verified all the requirements of the rocket mission for the engine, and provided strong support for the solidification of the engine’s technical status, the establishment of product technology baselines, and the improvement of reliability.
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 active Long March 5, with a thrust of 130 tons.

The reporter learned from China Aerospace Science and Technology Group Co., Ltd. on July 23 that the main engine of my country’s manned moon landing rocket was tested in the Fengzhou Test Area of the Sixth Academy of Aerospace Science and Technology Corporation, and achieved continuous success. This test run verified the engine flight mission profile, and provided strong support for the solidification of the engine technical state, the establishment of the product technical baseline, and the improvement of reliability.
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.
