Its successful development has realized the leap from a 5-meter-level diameter to a 10-meter-level launch vehicle storage tank in my country, and also marks that my country has become the third company in the world with the development capability of a 10-meter-level ultra-large-diameter storage tank after Russia and the United States. The country has laid a solid foundation for the development of my country’s heavy-duty launch vehicle engineering.
Hu Zhenggen, deputy chief designer of the heavy-duty launch vehicle of the Rocket Academy, introduced that expanding the diameter of the storage tank to the 10-meter level seems to be just the diameter multiplied by 2, but the actual development difficulty is not as simple as doubling, and the process almost challenges the limit of my country’s industrial basic capabilities , but it also fully drives the development of advanced materials, advanced technology, high-end manufacturing and other related basic industries, and plays a positive role in accelerating the transformation and upgrading of my country’s manufacturing industry, driving the development of high-end equipment in my country, and promoting the construction of a strong manufacturing country.
The project team innovated with the model of national large-scale cooperation and brainstorming, united more than 20 domestic superior units, and carried out collaborative research. It took more than 6 years to open up the entire development chain from materials, design, component forming, assembly and welding, and test assessment. The road has realized the upgrading of the design and manufacturing technology of large-diameter tanks for launch vehicles in my country. Previously, the team has successively completed the important components of the tank – the overall transition ring of the 10-meter tank (Figure 3), the melon petal sample of the 10-meter tank (Figure 4), the bottom ring of the 10-meter tank ( Figure 5) …

The official account of the Rocket Schoolhas updated the new developments of its Darwin II rocket in the past two days. Let’s take a look at ▲Wan Mei, the co-founder of the Rocket School and the deputy commander of the rocket team: “The first rocket of the Rocket School——Darwin II It is a small liquid carrier rocket with a total length of 30 meters, a diameter of 2.25 meters, a take-off weight of 54 tons, a take-off thrust of 70 tons, a carrying capacity of 500 kg in low-earth orbit, and 300 kg in SSO orbit. Currently, the development of the rocket is proceeding smoothly according to the project progress. It is expected to complete the general assembly test by the end of this year, and choose an opportunity to launch in the first half of next year.”
▲ Li Wei, deputy chief engineer of the Rocket Group: “The Darwin 2 (DW-2) launch vehicle will be established in 2021 and will be completed by May 2022 The design work of all the schemes has been completed, and it is transferred to the initial sample engineering development stage. At present, the overall and subsystem design of the initial sample stage has been completed. The corresponding research and development work will be carried out in accordance with the completion of the assessment flight test of the remote first plan in mid-2024. The DW-2 rocket needs to overcome the three-stage problems of liquid rocket design and development, system performance optimization and upgrading, and low-cost reusable commercial rocket formation. Therefore, we need to focus on improving the overall design capability of liquid rockets in the development process of the DW-2 follow-up rocket, upgrade the company’s self-developed electric pump engine, and aim at recyclable rockets in the future to tackle key problems in related recyclable technologies.
DW- 2. The follow-up rocket adopts the electric pump engine technology. The electric pump engine has inherent advantages in realizing large-scale variable thrust and multiple starts of the engine, which has laid a good foundation for the company to realize rocket recovery in the future. At the same time, it can be reused in the future The Company is also actively researching and researching 3D printing technology and composite material technology.”
▲Cheng Wei, founder of Rocket School: “The engine of Rocket School’s first rocket was outsourced, and the purpose is to realize the whole rocket to the sky first. Form a closed business loop as soon as possible. The company is also independently developing core technologies and engines, and plans to replace them in the second and third rounds… The Rocket School uses an electric pump engine in the future. The principle, structure and control method are simpler than traditional methods. ; In terms of reuse, it also has advantages over other companies using traditional gas generator cycles.”
▲Supplementary to the news that DW-2 passed the review of the program to the initial sample stage in January 22: The first sub-stage of DW-2 Yaoyi liquid launch vehicle uses a 70-ton liquid oxygen methane engine “LY-70”, and the second sub-stage adopts A 10-ton vacuum version of the liquid oxygen methane engine “LY-10V” (Figure 3), 300kmLEO carrying capacity of 470kg.
▲ Let me add the news that the DW-2 engine development plan was approved in December 21: The first sub-stage of the rocket sent Yaoyi liquid carrier rocket “Darwin II” uses a 70-ton liquid oxygen methane engine, and the second sub-stage uses a The 10-ton vacuum version of the liquid oxygen methane engine, “Planned for the first flight in early 2023″, uses the design idea of ”integration of ship and rocket test and launch” to double the load capacity, and launch the existing rocket through systematic structural optimization and application of new materials. Efficiency improvement is “ten times better”. [Through the optimization and iteration of “Darwin 1” and “Darwin 0”, and the finalization of three launches, it is planned to initially form a full-process service capability of space biomedicine integrating high-frequency launch vehicle launch service capabilities and space life science experiment capabilities in 2025. 】(At this time, the DW-2 capacity in Figure 6 is LEO600kg, SSO350kg )
The carrying capacity of the “Darwin II” rocket seems to be very Schrödinger. In addition, “Darwin I” and “Darwin Zero” are completely missing. Except for a second-stage engine LY-10V delivered by Kyushu Yunjian, “Darwin II” has never seen any other physical photos. Can it be launched in 2024?
