Although time is limited, Yang Xiaoyun still tried his best to introduce the general situation of Haoyu Aerospace Technology Co., Ltd. to Wu Hao.

After listening to Yang Xiaoyun's introduction, Wu Hao put down his pen, then nodded slightly, and said to her and the others: "Since the Aerospace Business Department was separated and established Haoyu Aerospace Technology Co., Ltd., I have never counted on you be profitable in the short term.

So you don't have to worry about this, I can still handle it. Not only that, in the next three to five years, the company will increase investment every year to promote the smooth progress of various projects under Haoyu Aerospace.

And your most important task at present is to promote the sound and rapid development of these projects, which is the most important. Of course, profitability is also important, after all, it can relieve some of the pressure on the head office.

And I have separated you for the sake of convenience and profit. However, compared with these projects currently underway, the profitability aspect is relatively secondary. "

Speaking of this, Wu Hao looked at Yang Xiaoyun and nodded, "I am quite satisfied with the overall operation of the company, and your work situation is obvious to all.

I hope you can make persistent efforts in this area and strive for better results.

Compared with other aspects of work, your work is still in operations. Actively develop the market and tap potential customers, this is what you will focus on in the future.

Don't limit your eyes to our one-acre three-point land, you can open your field of vision wider and wider. "

You mean the overseas market. Yang Xiaoyun couldn't help asking.

Wu Hao nodded and said: "That's right, compared to the domestic market, the international market is larger, with more potential customers and full potential for development.

You should use it to open up the market in this area and do your best to tap potential customers.

As for those difficulties and problems that do not exist in China, it is not difficult. Can you deal with them flexibly in this regard?

If you have no money, you can get a mortgage. Our major investment banks are very interested in this kind of business.

It is easy to handle without technology, we can help them teach from scratch, including teaching and meeting.

It’s easy to do without satellites. We can help them cover the entire process from design to manufacturing to launch. At that time, they only need to pay to receive and use it.

It's easy to do without interest. Cultivate their interest and explain to them the benefits of related satellites and spacecraft, such as communication satellites, optical remote sensing WeChat, earth resource exploration satellites, etc.

As long as the work is done, I don't believe they are not interested.

For the overseas international market, our biggest dilemma lies in other aspects. In terms of market competitiveness, we are no worse than those other international aerospace technology companies, and the related costs are very cheap.

You should make good use of your advantages in this area, make use of your strengths and avoid your weaknesses, and strive to make a name for yourself in the international market. "

Yes, you can rest assured that we will start the layout of the international market as soon as possible, and strive to enter the international market as soon as possible and win orders. Yang Xiaoyun responded seriously to Wu Hao.

Well, that's it. Wu Hao nodded, and then said to Zhou Xiangming, "Then we will go to the technical department, and you will arrange it."

Zhou Xiangming nodded when he heard the words, then looked at the crowd, then smiled at Wu Hao and said, "As the person in charge of technology, let me briefly report to you.

First of all, let's talk about the launch vehicle project.

At present, our most important two projects are the Jianmu-5 bundled booster medium launch vehicle, which will make its first flight early next year.

It will make its maiden flight next spring, sending our first unmanned experimental spacecraft into space. "

New arrows and new ships are extremely difficult and risky. Wu Hao said.

Zhou Xiangming nodded and said: "That's right,

The difficulty is great, and the risk is not small. The success rate of the rocket's first flight is not even half, which can be said to be very low.

And the success rate of the first flight of the new spacecraft is not high. It is not a small challenge for us to combine the two to launch together.

However, we are full of confidence in this Jianmu-5 bundled booster medium launch vehicle. We are also very confident about our first unmanned test vehicle.

Let’s talk about the rocket first. The basic technology of this Jianmu-5 bundled booster medium-sized launch vehicle is actually derived from our Jianmu-2 launch vehicle. The technology can be said to be very mature.

The difficulty of this rocket is how to bundle the first-stage rocket bodies of three Jianmu-2 rockets together for launch.

This is not an arithmetic problem where one plus one equals two. It involves a lot of complicated commissions. The most important one is the addition of two booster rockets, which are the same size as the rocket's first-stage rocket body structure.

This will inevitably affect the center of gravity of the rocket and affect the flight attitude of the rocket. Moreover, after adding two booster rockets, the take-off weight of the rocket will also increase, which is also very stressful for the rocket itself.

Secondly, it is the change of rocket aerodynamics. The addition of two booster rockets will not change the overall aerodynamic shape of the rocket and affect the flight attitude of the rocket. In this regard, an adjustment test must be carried out.

Compared with the launch of this Jianmu-5 rocket, its recovery work is also very complicated.

This time, two booster rockets will be recovered at one time. These two booster rockets basically landed at the same time. How to control them precisely without affecting each other is also a big problem for technicians. .

In addition, the rocket's first-stage rocket body will be recovered, which takes a few seconds to escape from the two boosters, so after the two booster rockets land, the first-stage rocket body will also land.

This also means that three rockets will be landed on the landing site at one time, which is also a very difficult test for the entire landing site and even the entire recovery staff.

If one of the three rockets lands, if there is a problem, it will inevitably affect the other two, resulting in the failure of the entire launch mission.

Therefore, it is necessary to ensure that the entire recycling process is accurate, so that nothing can go wrong, and the rest depends on God's will.

Although we don't believe in this, we have already done what we can, and sometimes it really depends on luck.

In addition, this time, there is no escape tower on the Jianmu-5 rocket launched by our unmanned test spacecraft. We fully adopted the design concept of the Dragon spacecraft, using the thrust reverser engine on the return capsule of the spacecraft to escape.

There is no fairing on the outside of the spacecraft, and rockets will propel the spacecraft into space. If the rocket fails during this process, the thrust reverser engine on the spacecraft's return module will ignite immediately, the spacecraft's return module will be separated from the faulty rocket, and then the parachute group will be thrown out, and then it will land smoothly.
