For them as doctoral students, life is still very stressful. To be admitted to the doctorate, the age is basically twenty-six or seventeen years old, and the average is around thirty years old. For them, this age is the most difficult time in their lives, especially for them, who are engaged in technology, and they are also engaged in space rocket and satellite technology.

The development of domestic commercial aerospace is still relatively slow, and most of them basically go to public institutions after graduation, and their salaries are still relatively small.

Of course, that was after I went, and now during the doctoral period, although there are certain subsidies and scholarships, compared to many people who have married and had children, as well as living and socializing, life is still relatively cramped.

This time I encountered a free dinner, especially if it was so rich, so everyone inevitably couldn't control themselves.

As for Chen Zhihong, he even took care of the situation of his own students, so he no longer spoke out to persuade him.

Compared with the young people who gobble up, Chen Zhihong eats more slowly and logically. Wu Hao also accompanied him.

Xiao Wu, the main purpose of our visit this time is to observe your launch. I was sorry I didn't come to witness your first retractable rocket launch and recovery last time.

But this time it's also good, we can finally see the full picture of this ultra-low-cost launch vehicle.

Chen Zhihong wiped his mouth, and then said to Wu Hao: "Ultra-low-cost launch vehicles, in fact, we have been studying for many years, but how to control the manufacturing cost of rockets is a very complex and difficult problem.

How to reduce costs, that can only be from the material and technology efforts. However, for high-risk products such as launch vehicles, the most stringent requirements are often materials and technologies.

So, that's a contradictory question. How to reduce costs while ensuring the reliability of launch vehicles is a difficult problem for many rocket technology research and development personnel.

And obviously in this regard, you are on your way to the future. ”

Chen Zhihong first praised him, and then then asked him: "What did you think at the beginning, and how did you balance the relationship between the two?" ”

Hearing Chen Zhihong's question, the doctoral students and other experts who accompanied him also stopped the rhythm of their meals and began to listen carefully.

Wu Hao shook his head with a smile when he heard this: "Actually, I didn't think about it that much. When we first set up the project, we were thinking about how to save money and how to come.

On the one hand, we are a private enterprise and do not have such strong financial support, so we must be careful and do the most with the least money.

On the other hand, since we want to engage in private aerospace, we must focus on the market. The products we develop must also have very strong market competitiveness.

So where is the market competitiveness of launch vehicles, reliability, safety, carrying capacity, and one of the most important is cost.

In fact, the difference between the first four is not too big, and the only thing that can open up the gap and affect market competition the most is cost.

If we can control the cost of rocket development and manufacturing, it means that we can win the competition with similar products on the market at a very cheap payload launch price, so as to obtain orders.

It was also along this line of thought that we began the development of two types of rockets.

So how to reduce the cost of carrying rockets, there are no more than three solutions. First of all, the first type of rocket, a large payload, can transport more weight of the load, so that the cost per kilogram of load is naturally reduced. It's just that the carrying capacity has increased, and the cost of the rocket has naturally increased. Moreover, the technology of large-load rockets is relatively high, which is not suitable for us for the time being.

So we set our sights on the other two solutions, first of all, the first is to reduce the cost of rocket manufacturing and launch, anyway, conventional rockets are disposable, non-recyclable, so why do we make rockets so good, as long as they can be used.

To give a very simple example, like the spraying on the rocket, if it is normal spraying, it will cost hundreds of thousands, and we have this money left, although it is a little ugly.

Of course, we can also sell the rocket body spraying as advertising space, for example, this time, we sold the rocket body spraying to an e-commerce company for more than one million yuan, which is equivalent to recovering part of the cost in advance. ”

Hearing Wu Hao say this, Chen Zhihong, his doctoral students and others couldn't help but widen their eyes, and their hearts boiled like a group of horses. complained again and again.

This rocket can still play like this, this is too picky. Sure enough, there is still no business or treachery.

It is also in accordance with this idea that we can save money, and together with the new hybrid liquid fuel we use, the combined cost of manufacturing and launching its rockets is more than half cheaper than that of conventional rockets, so that we also have a strong market competitiveness.

In this way, I say, so many units and commercial companies are willing to hand over orders to you, it turns out that it is so cheap. Chen Zhihong suddenly realized, but then asked: "What about the safety and reliability of the rocket, and how do you ensure the reliability and safety under the condition of reducing costs in this way." ”

These two are not directly related to the cost of the rocket. There is a certain impact, but the impact is not as huge as we think. In fact, where we have to use enough materials, we are also very willing.

Saying that, Wu Hao took a sip of hot soup and said with a smile: "On the other hand, this is also related to our encouragement of innovation, we encourage everyone to be bold and innovative, whether it is researchers, manufacturing personnel, or employees of other companies." As long as you can put forward feasible suggestions, solutions, and inventions, or even ideas, you can get certain generous rewards according to the situation. From thousands to tens of thousands, hundreds of thousands, and even millions.

The old technician in one of our manufacturing workshops, with more than a dozen related processes and invention patent technologies, has received nearly 10 million bonuses from the company, and every year, we will pay him a certain amount of fees.

With this bonus, he bought a villa in Anxi and settled down, successfully jumping into the elite class.

There are many similar examples, and many young employees in the company also get very generous remuneration for their related innovations and inventions.

So many employees are very rich, you can see that our company drives luxury cars, not necessarily the company's leading cadres, most of them are probably employees. ”
