In the field of aerospace, the pace of human exploration of the universe is accelerating, and commercial spaceflight has also made great progress in the process. Recently, the hyperbola-2 reusable liquid oxygen methane verification rocket of Beijing Interstellar Glory Space Technology Co., Ltd. successfully conducted the second flight test at the Jiuquan Satellite Launch Center in China. This mission not only realized the reusable flight of the rocket, but also verified a number of key technologies, breaking the wall for the development of China's commercial aerospace.

The hyperbola-2 rocket is an innovative product in China's commercial aerospace field, and its biggest feature is that it can be reused. In this flight test, the rocket successfully completed vertical take-off and landing, flight and landing, and achieved a complete multiplexing flight. This is not only a major breakthrough in China's commercial space technology, but also provides a more economical and efficient launch method for future space missions.

In this flight test, the technical indicators of the rocket have been fully verified. Among them, the parameters of the rocket, such as lateral displacement, landing position accuracy, landing speed and attitude angle, have reached the expected goals. The acquisition of these data is not only a comprehensive test of the rocket's performance, but also provides an important reference for subsequent research and development and optimization.

It is worth mentioning that the hyperbola-2 rocket completed the reuse maintenance inspection work in only 20 days after the first flight, and successfully performed the flight mission again. On the one hand, it shows the outstanding ability of the Interstellar Glory team in rocket design and maintenance, and on the other hand, it also shows that China's commercial aerospace has strong strength in rapid response and efficient operation.

Through this flight test, we obtained samples of flight data for each system, which will provide technical accumulation for more and more efficient multiplexed flights of reusable launch vehicles. At the same time, it also provides key technical verification for the development of medium and large reusable launch vehicle hyperbola-3. This will help promote the rapid development of China's commercial aerospace technology and enhance China's status and influence in the global aerospace field.

The successful flight of the hyperbola-2 rocket also further verified the natural advantages of liquid oxygen methane as a propellant. During this flight, the Reusable Depth Variable Thrust Liquid Oxygen Methane Engine of Focus 1 demonstrated the ability to quickly reuse flights. This not only illustrates the advantages of liquid oxygen methane propellant in terms of low cost, simple maintenance, and easy access, but also provides an important reference for selecting the appropriate propellant for future space missions.

In addition to the advantages of propellants, the flight also validated a number of key technologies. One of the most striking is the use of adaptive control technology. In order to better adapt to the characteristics of reusable launch vehicle mission airspace speed domain envelope, large change of dynamic characteristics, and large environmental uncertainty, the SQX-2Y rocket introduces an adaptive control technology with the ability to reconstruct the mission. The application of this technology effectively avoids the significant loss of carrying capacity and propellant consumption that may result from the nominal mission trajectory of offline planning, and improves the economic indicators of reusable launch vehicles.

In two flight tests, the adaptive control technology has been effectively verified. This not only provides a new solution for the economic improvement of reusable rockets, but also provides a more reliable guarantee for the successful completion of future space missions.

In addition to the breakthrough in control technology, the flight also verified the effectiveness of the intelligent health monitoring system of multiplexed rockets. The system can automatically monitor and diagnose the health status of each stand-alone equipment on the arrow according to the environmental data such as force and heat of the actual flight test in the early stage, and the ground BIT (built-in test) test data, and quickly give the conclusion of whether the stand-alone machine is working normally. The successful application of this technology solves the problem of inconvenient measurement of stand-alone equipment after loading, realizes the rapid confirmation of the electrical system status without dropping the arrow of the stand-alone product, and greatly improves the efficiency of reuse detection.

It is worth mentioning that the launch site used by the hyperbola-2 rocket in two flights is the first simple launch site system in China with integrated take-off and landing. The launch site does not rely on large-scale fixed ground facilities, and the ground gas filling and supply equipment and launch support equipment have the ability to be flexibly assembled and relocated, and at the same time have the ability to be unattended before launch, taking into account the gas-liquid preparation before launch and the processing needs after launch. The flexibility and efficiency of the launch site and related equipment and facilities provide new possibilities for the rapid response and efficient execution of future space missions.

The Interstellar Glory team demonstrated excellent technical strength and innovation ability in this flight test. Their self-developed arrow-borne stand-alone aircraft "Xingdong No. 1" and "Xingkong No. 1" achieved perfect blessings for the two missions. As the "control center" of the liquid rocket engine, "Xingdong-1" can realize efficient and intelligent control, and adopts a cross-redundant reconstructed design architecture, which can realize the functions of engine start-up and shutdown control, timing control, continuous variable thrust adjustment, remote measurement and collection, fault diagnosis, rapid detection and intelligent maintenance. As the "brain" of the rocket, the "Starcon-1" rocket computer adopts a multi-mode redundant design scheme based on advanced processors, which greatly improves the reliability of the system and the ability to detect and deal with faults. These technological breakthroughs and innovations have injected new impetus into the development of China's commercial aerospace.

In conclusion, the success of the second flight test of the hyperbola-2 reusable liquid oxygen methane verification rocket marks the achievement of China's commercial aerospace in the reusable technical capabilities of liquid launch vehicles.
