In which iSpace- Interstellar Glory in which it is the first Chinese Private Space Company to do so successfully commercially first out from sixty known private space companies in China People’s Republic of China.. Founded in Beijing 2016 located in Beijing Economic and Technological Development Zone or known for short as E-Town…
Recently, Interstellar Glory i-Space conducted a ground verification test for the grid rudder subsystem of the Hyperbola-2 reusable launch vehicle. The test process covered the entire mission of the Hyperbola-2 launch vehicle, and the verification test was a complete success. This subsystem is one of the typical key technologies for repeated use of launch vehicles. It has the characteristics of electromechanical integration and complex mechanical and thermal environment.
The grid rudder subsystem verification test was carried out in accordance with the full elements and the entire process of the flight test state. The test covered the typical flight mission conditions of the first sub-level of the Hyperbolic II carrier rocket, including the three stages of unlocking and unfolding, dynamic adjustment, and recovery and folding. All working conditions. During the test, the grid rudder carried out dozens of cycles of movement in the two directions of unfolding and swing. The movement was smooth and sufficient to avoid. The structural mechanism products and electrical products coordinated and matched and worked normally, which fully verified the grid rudder system. The correctness of the design and the coordination of the movement.
The grid rudder is a kind of rocket flight attitude control device. It has the technical advantages of high control efficiency, good control quality, reliable and economical technology to use the grid rudder to control the attitude after re-entering the atmosphere. As early as 2018 on the Hyperbola One verification rocket, Interstellar Glory carried out the grid rudder control technology verification, accumulating experience for the development of reusable liquid rocket related systems. Rudder Technology”). Compared with the grid rudder carried by the Hyperbola-1 verification rocket, the reusable grid rudder system carried by the Hyperbola-2 launch vehicle is a more highly integrated and complex system with more working modes:
-Dangyi When the sub-level is transported on the ground and in ascending flight, the 4 grid rudders are always kept folded and close to the outer surface of the
first sub-level arrow body; The folded state is unlocked and fully unfolded;
-When the first sub-level returns to the atmosphere, the arrow body relies on the grid rudder to swing the first sub-level attitude control and trajectory adjustment and decelerates pneumatically, and relies on the engine’s secondary ignition for power deceleration and hovering And landing, and finally achieve a sub-level vertical landing and recovery;
-When a child is completely vertical landing and recovery, the grid rudder will automatically fold, lock, and restore the initial state.
The design and realization of a fully reusable grid rudder system on a vertical recovery launch vehicle poses great technical challenges. It not only needs to meet the requirements of automatic folding and locking during ground transportation and ascent flight under severe thermal environment and multiple mission profiles. Development requirements such as automatic deployment and swing during the return process, and automatic folding and locking after recovery and landing. It also needs to meet the development requirements of good aerodynamic characteristics, reliability, maintainability and high supportability, with multiple mission profiles, harsh thermal and thermal environments, and dimensional chains. Features such as complexity and high integration.
The R&D team boldly innovated based on task requirements, and successively completed design and manufacturing difficulties such as comparison and optimization of multiple schemes, aerodynamic thermal simulation, electrical integration design of structural mechanisms, analysis of adaptability to complex environments, and overall 3D printing. The related technology can not only be used for the first-stage vertical recovery of a reusable launch vehicle, but also can be used for precise control of the wreckage landing point of a one-time use launch vehicle to improve the safety of the wreckage landing area.
The successful completion of this test is not only an important node in the development of the Hyperbola-2 launch vehicle, but also marks a breakthrough in another key technology for the vertical take-off and landing flight test of the hyperbola-2 verification rocket at the meter, Kilometer, and hundred kilometers level. , Laid a solid technical foundation for the complete success of the upcoming flight test…..
