Deep Blue Aerospace Co., Ltd. is headquartered in Nantong City, Jiangsu Province. At the same time, the company has rocket general and liquid engine R&D centers in Yizhuang, Beijing and Xi’an, Shaanxi, respectively, and a rocket power system test base in Tongchuan, Shaanxi…..

The Zhuque-3 ten-Kilometer vertical take-off and landing recovery test Reusable Carrier Rocket successfully completed the final assembly and will be launched in June!

🔷On April 15, the Blue Arrow Aerospace Zhuque 3 reusable rocket vertical take-off and landing recovery test arrow (hereinafter referred to as the ” Reusable Carrier Rocket “) successfully completed the “ten-Kilometer flight” transformation and final assembly work, and will be fully transferred to the final assembly testing and factory release stages. This is another new milestone that the Zhuque-3 reusable rocket is preparing to meet after the successful completion of the 100-meter vertical take-off and landing flight test on January 19.

🔷Compared with the 100-meter-level vertical take-off and landing, the 10-kilometer-level flight test not only significantly increased the flight height, but also added a series of difficult challenges for the verification of key technologies for recovery and reusability rockets, such as the first time under transonic speed conditions The engine-grid rudder-cooling attitude control joint control was carried out, the first unpowered taxiing test was carried out in a wind environment at an altitude of 10 kilometers, and the engine was re-started in the air under the condition of high dynamic pressure in the return section for the first time.

🔷According to Blue Arrow Aerospace’s ten-Kilometer-level vertical recovery flight test plan, the modified test arrow will take off with a thrust of 80 tons, and after about 200 seconds of flight, it will fly to an altitude of about 10 kilometers. In order to meet the recovery needs, this flight test mission built a new recovery site, and through several high-definition camera devices and optical fibers arranged around the site, the landing process of the test arrow and the on-site images after landing can be transmitted in real time to a location 5 kilometers away. The command hall allows the hall commander to perform post-processing work such as leaking the remaining fuel of the test arrow remotely from a remote location. This process is also an exploration and exercise of the safe post-processing process for the future Zhuque-3 sub-stage recovered arrows.

🔷In the future, the test rocket will move to the general testing stage and is expected to arrive at the Jiuquan Satellite Launch Center’s Blue Arrow Aerospace liquid oxygen methane rocket launch site in May, and the launch mission will be carried out in June.

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.
