Before the financial crisis started, when it was already foreseen.
Zhang Xingyang had raised the issue after talking about this matter with Zhou Zhengxiong.
If the country can obtain some benefits from this incident, it hopes to use part of it to invest in the construction of a hypersonic wind tunnel group.
At that time, Zhou Zhengqun said with a smile: "If what you said is true, then it won't be a problem even if I give you all the money!"
But at that time, Zhou Zhengxiong was mostly just joking. After all, the occurrence of the financial crisis was almost impossible in everyone's minds at that time.
Now Zhang Xingyang is ready to let Zhou Zhengxiong fulfill his promise!
"Mr. Zhou, is it time to honor the construction cost of the hypersonic wind tunnel that you agreed on before?"
Zhang Xingyang, who was sitting on the sofa, looked at Zhou Zhengxiong expectantly.
Zhou Zhengxiong, who was originally in a good mood, suddenly felt a little embarrassed when he remembered what he had said.
After all, at that time I didn’t really believe that a financial crisis would really happen, so what I said was a bit too full.
It is not so easy to cash out at this time, although in the process of fighting against the Quantum Fund, a lot of money was indeed made.
But for the mines, forest farms, fisheries, etc. that are in hand, the opinions above are still in favor of self-development, and the money should basically be invested in this area!
Therefore, the funds that can be used to build a hypersonic wind tunnel group are definitely not as much as mentioned before.
"Xingyang, although we have made a lot of money this time, I just told you that the industries we obtained will most likely 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.
This situation was actually expected by Zhang Xingyang, and he never thought that he would be able to get all the benefits.
During the entire financial turmoil, according to Zhang Xingyang's estimate, the country generated at least US$6 billion from Quantum Fund and other Western funds.
In fact, it does not cost so much money to build a hypersonic wind tunnel. With about 2 billion US dollars, we can build several hypersonic wind tunnels with test speeds of around Mach 15.
"Mr. Zhou, we actually don't need that much money. A dozen or two billion US dollars is enough."
Zhang Xingyang looked at Zhou Zhengxiong, who looked a little bad and said.
Before meeting Zhang Xingyang, Zhou Zhengxiong had actually gotten to know other people working in the aerospace system.
Wind tunnels can be divided into low-speed wind tunnels, high-speed wind tunnels, and hypersonic wind tunnels according to different test speeds.
The wind tunnel that Zhang Xingyang proposed before has a test speed of Mach 15, which is top-notch even among hypersonic wind tunnels.
Generally speaking, low-speed wind tunnels use fans to simulate aerodynamic conditions, while high-speed and even ultra-high-speed wind tunnels use shock wave technology.
Only this kind of technology can achieve hypersonic speeds above Mach 5 or even Mach 10. Of course, the single experiment time of such a wind tunnel is also quite short.
Being able to maintain it within 100 milliseconds is considered a leader in the industry!
"The fact that I was able to get so much money this time is basically all due to you. Logically speaking, I shouldn't refuse the figure 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 tactfully, hoping that Zhang Xingyang could understand their difficulties.
At this time, domestic foreign exchange was still relatively scarce, so Zhang Xingyang didn't really care whether he got US dollars or domestic currency.
As long as there are enough funds, it is enough to build a hypersonic wind tunnel group!
"Basically, we don't think much about importing equipment from abroad in hypersonic wind tunnels. It makes no difference to us whether the US dollar or the domestic currency." Zhang Xingyang said almost without any thought.
"And our own detonation shock wave technology is not very weak, and it will not have much impact when used."
"About 10 billion is enough. Of course, this does not include the cost of land."
At this time, although land prices across the country were not as crazy as in later generations, signs were already showing.
The wind tunnel group requires a large space, and as a large power consumer, each start-up test consumes 10,000 kilowatt-hours of electricity.
Such a large power consumption means that it cannot be built in deep mountains and old forests.
Even if you build your own power plant, it needs to be built in a place with convenient transportation.
Because of such large power consumption, except for thermal power plants or nuclear power plants, it is difficult for other wind power or solar power plants to keep up.
As for hydropower, the Three Gorges project has not yet started construction work at this time and 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 planning to build?”
"Is 10 billion enough?"
After Zhou Zhengxiong agreed to solve the land problem, he asked two questions in succession.
In previous internal discussions, the Rocket Research Institute has actually concluded that at least three wind tunnels,
A high-speed wind tunnel with a test speed between Mach 5 and Mach 10, mainly used to test some small and medium-sized rockets and satellites.
The remaining two test speeds are above Mach 10, and one of them has a test limit of Mach 15. They are mainly used to explore hypersonic missiles.
The other is mainly used to simulate high-speed conditions on the sea. It 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. However, 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 might be a bit reluctant.
"If you don't count the investment in thermal power plants, it should be sufficient. However, if the power plants transmit power from other places, it would be too troublesome."
"So it is certain to build a power plant by ourselves. It will probably cost about one billion in construction costs."
At this time, Zhang Xingyang was somewhat nostalgic for the "Space Three Gorges" space power station built in China decades later.
By transmitting electricity through microwave technology, you don’t need to worry about using electricity at all!
"Then let's do this. 11 billion yuan will be allocated from the previous profits for you to use for the construction of the hypersonic wind tunnel group!"
Finally, Zhou Zhengxiong made the final decision and promised Zhang Xingyang the funds for construction.
The last chapter of today will probably be after 12 o'clock. My arm is injured and I need to take a break.
