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.
