Chapter 2519 Lunar Science Observation Station Project Meeting (A)

In a conference room at the Linghu headquarters in Anxi, Wu Hao and Zhang Jun gathered together to participate in relevant work meetings about Haoyu aerospace work and the lunar scientific expedition station project.

This project is currently in the implementation stage, so as supervisors, Wu Hao and others need to understand the progress of these projects from time to time and make final decisions based on the progress of the projects.

Although Haoyu Aerospace is an independent joint-stock company, its controlling shareholder is Haoyu Technology, so its development and decisions are ultimately subject to the opinions and decisions of Haoyu Aerospace, the board of directors, and Wu Hao.

In order to prepare for this work report, the first, second and third leaders of Haoyu Aerospace, including relevant technical experts, have also appeared. Yu Chengwu, Yang Xiaoyun, Zhou Xiangming, as well as Dr. Guo Yulong, the general manager of the manned spacecraft project, and the director of the lunar patrol and exploration project

The specific person in charge, Dr. Shi Zhaopingshi, and Professor Zhang Qutong from Xingchen Laboratory, as well as experts in rockets, payloads, and engineering, all sat down at the conference table to participate in this meeting.

After Zhang Jun gave a eloquent opening speech, Wu Hao, who was sitting in the front seat, looked at everyone and said: "Okay, let's stop with these polite and official remarks, and let's get down to the main topic.

I want to know the progress of each project, where should I start first?"

Speaking of this, Wu Hao glanced at everyone present, and seeing that none of them spoke, Wu Hao immediately said: "Then let's go through it one by one, starting with the rocket project."

Hearing Wu Hao's words, Yu Chengwu, who was sitting on one side, turned around and said to Wu Hao: "I'll talk about the launch vehicle, because I am responsible for the launch vehicle technology, although I have focused most of my attention on it due to work.

It’s focused on company management and operations, but I’m still relatively clear about launch vehicle matters.”

Speaking of this, Yu Chengwu opened a folder, then took out a transparent tablet, then connected it to the big screen, and then preached to everyone.

“At present, our Haoyu Aerospace rocket family mainly includes Jianmu-1, Jianmu-2 rocket series, Jianmu-5 bundled rocket, Jianmu-7 rocket, and Jianmu-9 rocket.

The Jianmu-1 rocket is the first low-cost conventional two-stage launch vehicle we have successfully developed. We use semi-solid foam propulsion fuel on it, making its carrying capacity about 1.5 times that of ordinary liquid rockets.

With this rocket, we successfully entered the commercial launch vehicle launch market and successfully entered the aerospace field.

However, the shortcomings of the Jianmu-1 rocket are also very obvious, that is, because it has a small diameter and the fuel it can carry is limited, its carrying capacity is relatively weak and it can transport some light loads.

In addition, although it is designed and developed using low-cost technology, it is still a conventional model and cannot be recycled and reused, so the cost is relatively high.

Therefore, since our Jianmu-2 series rockets were successfully developed and put into use, the Jianmu-1 rocket has basically not been used much anymore. However, there will still be some special payloads and launch tasks that may be used on the Jianmu-1 rocket.

Number.

For example, the Jianmu-1 rocket has performed extremely well for launch missions in low-altitude orbits and near the Karman Line, as well as sounding research missions in the high-altitude atmosphere.

At present, the main force of our commercial launch is still the Jianmu-2 series launch vehicle. Since its successful development and first flight, it has been the main force of our commercial launch business. It should be said that in recent years, more than 60% of Haoyu Aerospace’s

All sales come from the Jianmu-2 series of rockets.

Because of its success, we have added many improved models to the Jianmu-2 series of rockets, such as the Jianmu-2 modified rocket with increased carrying capacity, and the Jianmu-2T rocket that can complete the recovery of the core two-stage rocket.

.There is also the Jianmu-5 medium-sized launch vehicle that we use two Jianmu-2 core first-stage rocket base boosters bundled onto the Jianmu-2 rocket, etc.

Of course, both Jianmu-2 and Jianmu-5 are intelligently used for some conventional space launch missions and cannot meet our manned space launches and lunar exploration missions.

Therefore, we have developed the Jianmu-7 single-body rocket with greater thrust, and the Jianmu-9 heavy-lift launch vehicle that bundles two core-first-stage rockets with the Jianmu-7.

At present, our Jianmu-7 series rockets are mainly used to launch some large payload missions, as well as our manned space launch missions. In addition, it is also the launch vehicle for the lunar ground patrol probe in our previous two lunar exploration missions.

.

According to the lunar exploration plan, the Jianmu-7 rocket will become our main transport rocket for carrying people to and from space in the future. In other words, all future manned missions will be undertaken by the Jianmu-7 launch vehicle.

Therefore, in the future, the Jianmu-7 rocket will be more suitable for a series of manned launch missions in the future, so we will continue to carry out relevant improvement and optimization work on the basis of the Jianmu-7 rocket.

For example, it greatly increases its safety and reliability and adopts a multi-channel and multi-system coexistence mode. Even if one system fails, another system will operate normally, which greatly increases the safety and reliability of the rocket.

In addition, in addition to the recycling of core first-stage rockets and fairings, we are also actively developing recycling and reuse technology for second-stage rockets.

Regarding this technology, we have already verified it on the Jianmu-2T launch vehicle and achieved success. We are currently conducting research on the basis of this technology and strive to conquer this technology as soon as possible.

If it can be realized, then the cost of sending people to space and transporting materials to the moon in space will be further reduced in the future. This will help us greatly save costs, and will also help the commercial transformation of these projects, so that they can be quickly realized

value."

Since this technology has been successfully used on the Jianmu-2T launch vehicle, why not apply it directly, but continue to research and overcome it? What are the difficulties? Zhang Jun asked Yu Chengwu after hearing this.

Hearing Zhang Jun's question, Yu Chengwu immediately nodded and answered: "The launch vehicle technology is very complicated. Although Jianmu-2 and Jianmu-7 are both retractable launch vehicles, the technology of Jianmu-7 is better than that of Jianmu-7."

No. 2 has many difficulties. If you want to successfully apply the technology on Jianmu-2 to the Jianmu-7 launch vehicle, it is not just as simple as changing the increase value. Its structure, materials, starting shape, and recycling methods will all

There will be changes.

To give a very simple example, as the volume of the core and second-stage rocket of the Jianmu-2T rocket increases, its strength must also increase accordingly. Otherwise, it is likely that it will not be able to withstand the speed and air resistance when re-entering the atmosphere, thus

The rocket body deformed and cracked, and the entire second-stage rocket was likely to disintegrate in the process."
