Military Technology

Anxi, a conference room at Linghu headquarters, Wu Hao and Zhang Jun gathered together to participate in related work meetings on Haoyu's aerospace work and the lunar scientific research station project.

At present, this project is already in the implementation stage, so Wu Hao and the others, as regulators, need to keep abreast of the progress of these projects from time to time, and give final decisions based on the progress of the project.

Although Haoyu Aerospace is an independent joint-stock company, its controlling shareholder is Haoyu Technology, so its development and decision-making 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 all appeared on the stage. Yu Chengwu, Yang Xiaoyun, Zhou Xiangming, Dr. Guo Yulong, who is in charge of the manned spacecraft project, Dr. Shi Zhaopingshi, the specific person in charge of the lunar patrol and exploration project, and Professor Zhang Qutong from Xingchen Laboratory, and the rocket, The load and engineering experts all sat at the conference table to participate in this meeting.

After Zhang Jun gave an eloquent opening speech, Wu Hao, who was sitting on the first seat, looked at the crowd and said, "Okay, let's stop with these polite and official interviews, let's get to the point.

I want to know the progress of various projects now, where should I start? "

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

Hearing Wu Hao's words, Yu Chengwu, who was sitting on the side, turned to Wu Hao and said, "Let me talk about the launch vehicle, because I am responsible for the launch vehicle technology, although I have already devoted most of my attention to it due to work. It’s on the management and operation of the company, but I’m quite clear about launch vehicles.”

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

"Currently, our Haoyu Aerospace rocket family mainly includes the 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 successfully developed by us. We used semi-solid foamed propellant on it, making its carrying capacity about 1.5 times that of ordinary liquid rockets. With With this rocket, we successfully entered the commercial launch vehicle market and successfully entered the aerospace field.

However, the shortcomings of the Jianmu-1 rocket are also obvious, that is, because of its small reminder, the fuel it can carry is limited, so its carrying capacity is relatively weak, and it can transport some light loads as much as possible.

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.

So since our Jianmu-2 series rockets were successfully developed and put into use, the Jianmu-1 rockets are basically not used anymore. However, there will still be some special payloads and launch tasks, which may be applied to Jianmu-1. ....

For example, for the delivery missions in low-altitude orbit and near the Karman line, and the sounding research missions in the high-altitude atmosphere, the Jianmu-1 rocket has completed very well.

At present, the main force of our commercial launch is still the Jianmu-2 series of launch vehicles. Since it was successfully developed and made its 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 The turnover comes from the Jianmu-2 series of rockets.

Because of the success, we have added many improvements 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 second-stage core rocket. . There is also the Jianmu-5 medium-sized launch vehicle that we use two Jianmu-2 core first-stage rocket seat boosters to bind to the Jianmu-2 rocket and so on.

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

So we developed the Jianmu-7 single-body rocket with greater thrust, and the Jianmu-7 bundled with two core first-stage rockets.

Arrows of the Jianmu-9 heavy launch vehicle.

At present, our Jianmu-7 series rockets are mainly used to launch some large-load missions, as well as our manned space launch missions. In addition, it is also the launch vehicle for the lunar ground inspection 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 manned transportation to and from space in the future. In other words, all future manned missions will be undertaken by the Jianmu-7 carrier rocket.

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, its safety and reliability are greatly increased, and the multi-channel and multi-system coexistence mode is adopted. Even if one system fails, another system will still operate normally, which greatly increases the safety and reliability of the rocket.

In addition, in addition to the recycling of the core first-stage rocket and the fairing, we are also actively developing the recovery and reuse technology of the second-stage rocket.

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

If it can be realized, UU Reading www.uukanshu.com will further reduce the cost of sending people into space and transporting materials to the moon in space in the future. It will help us greatly save costs, and it will also be conducive to the commercial transformation of these projects, so as to quickly realize value. "

Since this technology has been successfully applied on the Jianmu-2T carrier rocket, why not apply it directly, but continue to research and overcome it? What are the difficulties? Zhang Jun asked Yu Chengwu when he heard the words.

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 receivable launch vehicles, the technology of Jianmu-7 is more advanced than that of Jianmu-7. No. 2 is very difficult. To successfully apply the technology of Jianmu No. 2 to the Jianmu No. 7 launch vehicle, it is not only as simple as changing the increase value, but also its structure, materials, starting shape, and recovery methods. will change.

To give a very simple example, the core-stage rocket of the Jianmu-2T rocket increases in volume, and its strength must also increase accordingly, otherwise it may 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 secondary rocket likely disintegrated in the process.
