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.

Knowledge Posts

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.

On the 0813 30th  December 2023 Saturday  Hours Hong- Kong SAR – Beijing time CNSA –China National Space Administration , China, People’s Republic of China. Successfully launched the Chang Zheng- Long March 2C/Yuanzheng 1S Jiuquan Satellite Launch Center, Inner Mongolia, China, People’s Republic of China, and then successfully launched a new advance satellite internet technology.

The Long March 2C/Yuanzheng 1S carrier rocket ignited and took off at the Jiuquan Satellite Launch Center, and then successfully sent the satellite Internet technology test satellite into the predetermined orbit. This year, all 48 space missions of the launch vehicles developed by China Aerospace Science and Technology Corporation were a complete success. The satellite Internet technology test satellite was developed by the Fifth Academy of China Aerospace Science and Technology Corporation.

“Long March 2C” is a medium-sized two-stage room-temperature liquid launch vehicle developed by the First Academy of China Aerospace Science and Technology Corporation. Its main power uses dinitrogen tetroxide/uniform dimethylhydrazine (N2O4/UDMH) propellant. The arrow is about 42.3 meters long, with a first and second stage diameter of 3.35 meters, a take-off mass of 241 tons, and a take-off thrust of about 302 tons. Its low-Earth orbit transport capacity is 4 tons, and the maximum transport capacity in the 500-kilometer sun-synchronous orbit is 2 tons. When paired with the “expedition” In the “No. 1 S” upper stage state, the 700-kilometer sun-synchronous orbit has a transport capacity of 2.5 tons…

The “Yuanzheng-1″ commercial/”Yuanzheng-1S” (YZ-1S) upper stage was developed by the First Academy of Aerospace Science and Technology and was improved on the basis of the “Yuanzheng-1” upper stage. The upper stage has a diameter of 2.8 meters, is equipped with a YF-50D engine, uses dinitrogen tetroxide/uniform dimethyl hydrazine propellant, has 2 ignition capabilities, a vacuum thrust of about 0.66 tons, and a vacuum specific impulse of about 316 seconds. This upper stage is mainly aimed at short-term flight missions. It has system optimization and equipment streamlining based on the “Yuanzheng-1” upper stage. Its weight and cost are greatly reduced, and its working time is shorter. After being separated from the basic stage, it can immediately The ignition was accelerated and the entire flight mission was completed within one hour.

Since its successful first flight, the “Yuanzheng-1” commercial upper stage has carried out a total of 7 launch missions, all of which were carried out in conjunction with the “Chang 2-C” rocket. The “Chang 2C” rocket, paired with the “Yuanzheng-1S” upper stage, can perform various orbital launch missions such as low-Earth orbit, sun-synchronous orbit, geosynchronous transfer orbit, and earth-moon transfer orbit, and has the ability to launch multiple satellites in different orbits.

This launch is the 9th launch of the “Long March 2C” rocket in 2023, the 36th launch of the Jiuquan Satellite Launch Center, the 67th launch of China, and the 220th launch of the world. At the same time, this launch is also the final battle between China’s aerospace industry and the world’s aerospace industry this year. The total number of China’s space launches this year reached a record-breaking 67, and the total number of world space launches reached a new high of 220.

This mission is the 505th flight of the Long March series of launch vehicles.
