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.

Recently , the reusable liquid engine “Thunder-R1” independently developed by Deep Blue Aerospace conducted its first long-distance test run of 420 seconds under rated operating conditions. The test run time covered more than twice the flight time of the first stage of the reusable rocket “Nebula-1 ” ; The engine started and shut down normally, and the whole process worked stably. The test was a complete success, marking that the “Thunder-R1” engine entered the series boundary, life and reliability test stage.

As China’s first pin-bolt reusable liquid oxygen kerosene engine , this long-distance test run verified the reliability and stability of the system and components of the “Thunder-R1” engine under rated operating conditions. The engine status is stable and its performance is excellent. It demonstrates the technical strength and product leadership of Deep Blue Aerospace’s reusable rocket engine, and proves that the “Thunder-R1” is one step closer to being officially delivered, carrying out the high-altitude recovery test of the first stage of the “Nebula-1” rocket, and flying into orbit.

“ Thunder-R1″ is a liquid engine product specially developed for vertical recovery and reuse of launch vehicles. It currently demonstrates excellent performance in various aspects such as reuse, multiple starts, and wide-range thrust adjustment. 85% of the weight of this engine is made by 3D printing. It adopts a pump-back swing and has a compact structure. It is used as the main power for the first and second stages of the Deep Blue Aerospace “Nebula-1” recyclable and reusable liquid launch vehicle.

Up to now, the cumulative test run time of the same engine has reached 2,000 seconds, which has verified the anti-fatigue characteristics and service life of engine components in the harsh engine working environment.

The single ground ignition of the engine lasted 420 seconds. It assessed the long-range work coordination, process reliability and margin design of the entire engine and each component. According to real-time monitoring throughout the test run, the engine was working stably and in good condition. The test data is consistent with the set indicators, and all indicators meet the flight requirements of the “Nebula-1” rocket.

Long-distance test run is an indispensable and important link in the development, production and engineering application of a type of engine. The success of this long-distance test marks the rapid development of Deep Blue Aerospace’s reusable liquid oxygen kerosene rocket engine, and also provides strong power support for the subsequent “Nebula-1” rocket to enter orbit. Previously, the same “Thunder-R1” engine has completed starting and ignition test, complete machine test, secondary start test, and full flight sequence three-start test. In the future, we will continue to carry out ground testing work such as a series of working conditions for pulling deviation, swing test, life and reliability test for engineering applications. The “Thunder-R1” engine is the power foundation of the medium-sized launch vehicle “Nebula-1” and will cover the needs of liquid rockets entering orbit and first-stage recovery.
