A big country of aerospace with black technology

Chapter 118 A lot of small money~

Before the financial turmoil started, when it was already foreseen.

After Zhang Xingyang talked about this matter with Zhou Zhengxiong, he once brought it up.

If the country can obtain some benefits from this incident, it is hoped that part of it can be used to invest in the construction of hypersonic wind tunnels.

At that time, Zhou Zhengqun just said with a smile: "If what you said is true, then it is not a problem to give you all the money!"

But at that time, Zhou Zhengxiong was only joking. After all, the financial turmoil was almost impossible in everyone's mind at that time.

Now Zhang Xingyang is ready to make Zhou Zhengxiong fulfill his promise!

"Mr. Zhou, the construction cost of the hypersonic wind tunnel you promised earlier, should it be fulfilled this time?"

Zhang Xingyang, who was sitting on the sofa, looked at Zhou Zhengxiong expectantly at this moment.

Zhou Zhengxiong, who was originally in a good mood, now remembered what he had said, and instantly felt a little embarrassed.

After all, at that time, I didn't really believe that a financial crisis would really happen, so I was a little too full.

It is not so easy to cash in at this time, although in the process of confronting Quantum Fund, he did get a lot of money.

But for those mines, forest farms, fishing grounds and so on, the opinions from above are still inclined to self-development, and the money is basically invested in this area!

Therefore, the funds that can be used to build hypersonic wind tunnels are definitely not as much as previously mentioned.

"Xing Yang, although we have made a lot of money this time, as I told you just now, the industries we got may need to be developed by ourselves, and these funds may be used as start-up capital. to do construction work."

"So, the funds for you to build a hypersonic wind tunnel group may not be as much as promised before."

Zhou Zhengxiong looked at Zhang Xingyang with some embarrassment and said.

In fact, this situation was within Zhang Xingyang's expectation, and he never thought that he could get all the benefits.

During the entire financial turmoil, according to Zhang Xingyang's estimation, at least 6 billion US dollars were obtained from Quantum Fund and other Western funds in China.

The construction of a hypersonic wind tunnel actually does not cost so much money. With about 2 billion US dollars, several hypersonic wind tunnels with a test speed of around Mach 15 can be built.

"Mr. Zhou, we actually don't need that much money. A dozen or two billion dollars is enough."

Zhang Xingyang looked at Zhou Zhengxiong who had a slightly bad face and said.

Before meeting Zhang Xingyang, Zhou Zhengxiong had actually met other people who worked in the aerospace system.

According to different test speeds, wind tunnels can be divided into low-speed wind tunnels, high-speed wind tunnels, and hypersonic wind tunnels.

The wind tunnel proposed by Zhang Xingyang before with a test speed of Mach 15 is a top-notch existence even among hypersonic wind tunnels.

Generally speaking, low-speed wind tunnels use fans to blow air to simulate aerodynamic conditions, while high-speed and even ultra-high-speed wind tunnels use shock wave technology.

Only such a technology can achieve hypersonic speeds above Mach 5 or even Mach 10. Of course, the time for a single experiment in such a wind tunnel is quite short.

Being able to maintain 100 milliseconds is considered a leader in the industry!

"It's basically your credit for getting so much money this time. Logically speaking, I shouldn't refuse the amount you mentioned."

"But it's really not easy for us now, so we may not be able to give you so many dollars directly."

Zhou Zhengxiong said somewhat euphemistically, hoping that Zhang Xingyang could understand their difficulties.

At this time, domestic foreign exchange is still relatively scarce, so Zhang Xingyang doesn't really care whether he gets US dollars or domestic currency.

As long as there is enough funds, it is enough to carry out the construction of the hypersonic wind tunnel group!

"Basically, we don't think much about importing equipment from abroad for the hypersonic wind tunnel. It doesn't make any difference to us whether the US dollar or the domestic currency." Zhang Xingyang said almost without thinking.

"And our own detonation shock wave technology is not very weak, and it doesn't have much impact when used."

"About 10 billion is enough, of course, the cost of land is definitely not included here."

At this time, although land prices across the country are not as crazy as in later generations, they have already shown signs.

The wind tunnel group needs a large area, and as a big power consumer, every start-up test needs to consume 10,000 kWh of electricity.

Such a large power consumption means that it is impossible to build it in the deep mountains and old forests.

Even if you build a power plant yourself, you need to build it in a place with convenient transportation.

Because of such a large power consumption, except for thermal power plants or nuclear power plants, it is difficult for other wind power or solar power to keep up.

As for hydropower, the construction of the Three Gorges has not yet started at this time, so it will not be considered for the time being.

"Don't worry about the land issue, we will definitely solve it for you."

"How many wind tunnels are you going to build?"

"Is 10 billion enough?"

After Zhou Zhengxiong agreed to solve the land problem, he asked two more questions one after another.

In the previous internal discussions, the Rocket Research Institute has actually reached a conclusion that at least three wind tunnels,

A high-speed wind tunnel with a test speed between Mach 5 and Mach 10 is mainly used to test some small and medium-sized rockets and satellites.

The test speeds of the remaining two are above Mach 10, and one of them has a test limit of Mach 15, which is mainly used to explore hypersonic missiles.

The other is mainly used to simulate the high-speed situation on the sea surface, which is more special, and is specially used to explore hypersonic anti-ship missiles.

"It is mainly used to build three wind tunnels, one high-speed wind tunnel and two hypersonic wind tunnels, but it may also need to build some supporting facilities, such as a thermal power plant!"

After Zhang Xingyang did some calculations, he found that 10 billion may be too much.

"If you don't count the input of the thermal power plant, then it should be sufficient, but if the power plant is transmitted from other places, it will be too much trouble."

"So it is certain to build a power plant by ourselves. It will probably cost about one billion yuan in construction."

At this time, Zhang Xingyang somewhat missed the "Three Gorges in Space" space power station built in China decades later in the original history.

Power is transmitted through microwave technology, so there is no need to worry about power consumption!

"Then let's do this, allocate 11 billion from the previous income, and give it to you for the construction of hypersonic wind tunnels!"

In the end, Zhou Zhengxiong promised the funds for Zhang Xingyang's construction with the final word.

Today's last chapter may be after 12 o'clock, my arm is injured, take a break.
