In the second half of 2024 years, after China's first public Long March 9 heavy rocket, it is rare to hear its news, no, from the deep space exploration laboratory released the "China's fourth-generation spacecraft and commercial rockets", I saw the situation of the Long March 9 again, I have to say, this news is still a bit little.
Because this rocket is related to more tasks in my country in the future, and the Long March 9 has long been a rocket built against the American Starship, but many people see that it has changed a lot, so that there are many changes.
It's just that China has given the first flight time of the Long March 9, which means that its changes basically don't exist much, and the follow-up is to push it, and for the engine of this rocket research, China has also achieved a breakthrough in relevance.
Indeed, the research of the Long March 9 is already an "ultra-long topic", and many people are also looking forward to his early arrival, after all, the strength is very strong.
According to the comparative data, the "Starship" adopts an integrated design of ships and arrows, and consists of a "super-heavy" carrier rocket and a "Starship" spacecraft. The carrying capacity is 7400 tons, which can send 0 people to the moon, Mars or other distant destinations, or fly around the earth, the "Starship" system has a total length of 0 meters, a take-off mass of 0 tons, a take-off thrust of 0 tons, and both stages can be reused.
China's heavy-duty launch vehicle Long March 9 will be the largest type of rocket in China in the future, with one design and three configurations, with a Earth-Moon transfer orbit capacity of not less than 80 tons, and a low-earth orbit capacity of not less than 0 tons (the first stage is reused) and 0 tons (two stages of reuse).
Therefore, the difference in strength still exists, but under the slow promotion, it is still possible to enhance a stronger version, which actually depends on the needs of the mission, and China's goal at this stage is - the Long March 9 heavy rocket uses 10-meter rocket body diameter and high-performance liquid oxygen/methane, liquid oxygen/liquid hydrogen engine, mainly undertakes lunar exploration, Mars/asteroid exploration and large high-orbit satellite launches and other tasks, and performs large-scale low-earth orbit missions.
It can also be seen that the direct routes of the two are still different, which also shows that their respective pertinence is different, so let's just look at the data.
This time, China has seen the progress of the Long March 9, that is, it is already in the stage of deepening the demonstration of the plan. However, it should be noted here that although it is still at this stage.
但是關於它各方面的研究其實已經起步，去年已經公開說明瞭，YF-215的研究，其200t級全流量補燃迴圈甲烷機YF-215已經完成技術驗證，進行了長達千秒的試車，這些都說明瞭其突破性的成就是存在的，並且在不斷增強其研究速度。
Therefore, don't see the argument and already panic, think that it is still very early, in fact, other parts are already underway.
Indeed, China has clearly introduced the development timeline of the Long March 9, that is, China's heavy-duty launch vehicle adopts modular, general, and serialized development ideas, which is in line with the international trend and reflects some unique advantages, experts from the First Academy of China Aerospace Science and Technology Corporation said that through modular design, each part of the heavy-duty launch vehicle can be independently developed, produced and tested, and then combined according to different mission requirements, which improves R&D and production efficiency. At the same time, according to the point in time, the first flight of the Long March 9 heavy-lift launch vehicle is planned to be in 2035 years, and the first flight of the two-stage fully reusable configuration is planned to be 0-0 years.
What does this mean? That is, the first flight year of China's Long March 9 is in 2030 years, which should not change much, after all, there are still many years in this time, and there should be no problem.
所以，只要長征九號完成了首飛，那後續我國進行相關性的任務擴展，也就更加方便了。並且最初這一款火箭其實也針對過登月任務，但後續我國發展長征十號進行主力推動載人登月，這一款要是出來了，可以彌補任務階段之中的時間差。
Because in the future, China will not only implement its own manned lunar landing program, but also promote foreign astronauts to come to the manned lunar landing program, in this case, it is possible to see more missions carried out, even if the rocket cannot keep up with the pace of the mission, a variety of rockets can support each other, this is the benefit.
On the whole, it will take some time for the Long March 9 to make its first flight, and it will definitely take some time to start repeating the recovery test.
It's just that relatively speaking, these problems are not very big, after all, from the perspective of China's research rocket model, there are already a number of synchronous research models, but compared to repeatable rockets, this time is not so fast. This is a matter of patience, and in addition to the national team, many private companies in our country are also working on relevant repeatable rockets.
Including under this disclosure, it also shows that according to incomplete statistics, there are 20 commercial rocket companies in China, aiming at the industrialization needs of 0-0 years, planning 0 meters, 0 meters, 0 meters class medium and large reusable rockets, with a capacity range covering 0~0 tons.
Therefore, China's rockets have to wait to line up to the sky to achieve a new high in China's development in the aerospace field, which is worth looking forward to, and the Long March 9 is only one of China's various rockets, which is the basic situation.
