 During 16:00 Beijing Time  on January 19th , 2024, the Zhuque-3 VTVL-1 reusable vertical takeoff and landing recovery verification rocket (hereinafter referred to as the “VTVL-1 test rocket”) independently developed by Blue Arrow Aerospace was ignited and launched into space at the Jiuquan Satellite Launch Center in my country. . The flight time of this test was about 60 seconds, the flight height was about 350m, and the landing position accuracy was about 2.4m. The rocket landed smoothly, the landing point was accurate, and it was in good condition. The test mission was a complete success!

China, People’s Republic of China’s first stainless steel rocket – LandSpace Blue Arrow Aerospace’s reusable liquid oxygen methane rocket Zhuque 3!


🔷The Zhuque-3 reusable liquid oxygen methane launch vehicle is the latest product in the Blue Arrow space launch vehicle series. The diameter of the rocket body is 4.5m, the fairing diameter is 5.2m, the total length of the rocket is 76.6m, the take-off mass is about 660t, and the take-off thrust is about 900t.


🔷The power system adopts the Tianque series liquid oxygen methane engines independently developed by Blue Arrow Aerospace. Among them, the first sub-stage is equipped with 9 Tianque 12B (TQ-12B) engines with a sea level thrust of 1000kN; the second sub-stage is equipped with 1 TQ-12B engine with a vacuum thrust of 1183kN. Magpie 15B (TQ-15B) vacuum engine has a vacuum specific impulse of 3500m/s.


🔷Considering that the first stage can be reused, the entire arrow is equipped with 4 sets of retractable grid rudders as aerodynamic control surfaces for attitude adjustment and landing point control of the aerodynamic deceleration section of the first stage; landing legs are installed on the tail to achieve a Vertical landing during sub-stage recovery.


🔷The first sub-stage of Zhuque 3 is designed to be reused no less than 20 times. The low-orbit carrying capacity for one-time missions can reach 21.3t, and the recovery mission in the navigation area is 18.3t. It has the capability of multiple satellites with one arrow and flat-plate stacking satellite group shooting. The capability fully covers the launch needs of most payloads on the market such as LEO, SSO, GTO and other different orbits. After being put into commercial operation, it will greatly improve the networking efficiency of satellite Internet constellations.


🔷The Zhuque-3 rocket is China’s first stainless steel liquid launch vehicle, which can significantly reduce the manufacturing cost of the rocket and shorten the production cycle. Its high temperature resistance has obvious advantages in the rocket’s multiple returns and reuse. In addition, due to the low cost of liquid oxygen methane, the methane engine’s non-carbon deposits, easy maintenance, and full life cycle monitoring properties, the first-stage engine of the Suzaku-3 rocket can be inspected without lowering the arrow after the rocket is recovered, and can be refilled after refueling. flight, achieving true flight operations, and the launch cost can be reduced by 80-90% compared with disposable rockets.

Recently on the 5th January 2024, 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 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.

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.
