Rebirth 99 to become a car giant.

Chapter 967: Hyperspeed Wind Tunnel Laboratory and Aerospace Vehicles
Although rocket explosions do not happen often, they do occur every year.

This time, the starship finally exploded on the test platform, but it did not bring any bad impact on the reputation of Venusstar Technology.

It even made Venusstar Technology more well-known.

After all, the forty-story-high appearance of the starship still gave everyone a very big impact.

The world's largest launch capacity should not be underestimated.

At Venusstar Technology, they were also intensively analyzing the cause of the problem. They eventually found that the design requirements of a pipe in the engine did not match the needs of the engine under maximum thrust conditions, resulting in fuel leakage and causing the explosion.

This rectification is actually not difficult at all.

All departments quickly took action and began to prepare for the production of the next prototype.

At this time, a new laboratory of Venusstar Technology was officially put into use.

Taking into account the particularity of this laboratory, Venusstar Technology invited relevant personnel from AVIC and China Aerospace Science and Technology Corporation.

These are all potential customers of the laboratory.

"Mr. Cao, Mr. Zhao, your ultra-high-speed wind tunnel laboratory was built just in time."

"With this laboratory, our research on many hypersonic weapons and aircraft will be greatly enhanced."

Qian Junfeng didn't expect that Venusstar Technology had quietly launched another satellite.

Major aviation countries definitely have wind tunnel laboratories.

Even some car manufacturers have their own wind tunnel laboratories.

However, the ultra-high-speed wind tunnel laboratory is definitely different from the ordinary wind tunnel laboratory.

Human beings have an aerospace dream and always want to fly faster, higher and farther.

As early as the 20s, Qian first defined the concept of "hypersonic flight".

In the future, a new generation of aircraft will be able to travel thousands of miles per hour, allowing international trips to take place early and return late.

The research and development of a new generation of aerospace vehicles is inseparable from an important scientific device - the hypersonic wind tunnel.

Hypersonic wind tunnels artificially generate and control high-speed airflows, simulate the flow of gas around an aircraft, and obtain the aerodynamic characteristics of the aircraft, which is equivalent to artificially building a "flying sky" on the ground.

The faster the aircraft is, the stronger the "wind" produced by the wind tunnel is required.

Scientists measure flight speed using the ratio of flight speed to the speed of sound - the "Mach number".

During hypersonic flight, the huge kinetic energy of the aircraft will generate strong head shock waves and frictional resistance, heating the air around the aircraft to thousands or even tens of thousands of degrees Celsius, causing complex chemical reactions such as dissociation of air molecules and ionization of atoms.

"Thermochemical reactions in the air around the aircraft are beyond the scope of traditional gas dynamics research. We need to create new theories to describe them and build new wind tunnels to test them."

"We at Venusstar Technology are now fully committed to the development of various missiles, aircraft and other products, and the demand for wind tunnels has greatly increased."

"Ground tests for the development of new aerospace vehicles require even more powerful hypersonic wind tunnels."

Zhao Siyu has very high expectations for this new laboratory of Venustech.

Whether Venustech can continue to lead the development of the aerospace industry in the future is closely related to the integrity of various experimental equipment.

The hypersonic wind tunnel experimental platform provides a powerful tool for Venusstar Technology's hypersonic development. Now it can carry out scientific experiments that "can do what others cannot do, do what is difficult for others to do, and do what others are not good at", and solve those problems that "cannot be done, cannot be done well, and cannot be done accurately".

It will definitely provide support for the design and development of many products in the future.

Qian Junfeng was obviously very clear about this.

"Aerospace vehicle?"

Zhao Tianling from AVIC keenly grasped a key word from Zhao Siyu's words.

Although this was not the first time he had heard of this thing, even within AVIC, there was discussion about whether to cooperate with China Aerospace Science and Technology Corporation to develop an aerospace vehicle.

But there has been no formal project yet.

This was originally secret information between AVIC and China Aerospace Science and Technology Corporation. I didn't expect to hear related content from Venusstar Technologies now.

"Boss Zhao, has Venusstar Technology already been researching aerospace vehicles?"

The American space shuttle at that time was considered a typical aerospace vehicle. It could not only fly within the atmosphere, but also fly in space.

But the final fate is not very ideal.

Now that Venusstar Technology is planning to develop aerospace vehicles, Zhao Tianling is really looking forward to what it will look like.

“We do have a team developing related products, but the product has not yet been finalized.”

Zhao Siyu was not sure whether he was suitable to talk about the specific content of this product that had not yet been disclosed to the public, so he did not prepare for detailed communication.

However, the other party certainly doesn't want to give up easily.

Even Qian Junfeng from Aerospace Science and Technology was chasing Cao Yang and asked, "Boss Cao, this hypersonic wind tunnel laboratory is indeed very beneficial for the development of aerospace vehicles."

"We at Aerospace Science and Technology are also discussing the development of an aerospace vehicle with AVIC."

“Why don’t the three parties merge their projects together and discuss the development of this product together?”

Qian Junfeng feels that with the participation of Venusstar Technology, this aerospace vehicle will appear in front of everyone more quickly.

So I really want to pull the other party into the project.

Otherwise, it would be a bit awkward if the product they and AVIC have worked hard on for many years turns out to be inferior in performance to that of Venusstar Technology.

"The aerospace plane will be one of the key weapons for countries around the world to compete for air and space supremacy in the 21st century."

"America, the North Pole, China, and Germany are all researching space planes, but no one has actually succeeded. Most plans still rely on disposable launch vehicles to launch, similar to the old-fashioned space shuttle concept."

"Ideally, as a future aircraft, the space plane can take off horizontally like an ordinary aircraft and fly in the atmosphere at a hypersonic speed of 1.6 to 3 kilometers per hour. At an altitude of 30 to 100 kilometers, the flying speed is 12 to 25 times the speed of sound."

"Moreover, it can be accelerated directly into Earth orbit and become a spacecraft. After returning to the atmosphere, it can land at an airport like an airplane, becoming a means of transportation that can freely travel between heaven and earth."

"Before this, aviation and aerospace were two different technical fields, with aircraft and spacecraft operating in and out of the atmosphere respectively. The aviation transportation system was reusable, while the space transportation system was generally not reusable. The space plane can achieve full reusability and significantly reduce the cost of space transportation."

"AVIC has extensive experience in the aerospace field, Aerospace Science and Technology has accumulated many years of experience in aerospace flight products, and Venusstar Technology is involved in both aspects."

"I think the three-party cooperation can definitely produce very good chemistry."

Zhao Tianling immediately agreed to Qian Junfeng's proposal.

He is naturally very aware of the strength of Daystar Technology.

Future products such as aerospace vehicles rely on the strength of AVIC and aerospace technology, and it is difficult to see hope for mass production at least in the next ten years.

But if Venustech is brought in, he thinks it might take less than ten years for the product to be launched.

This is definitely something to look forward to.

"Much is known about the US space plane development program, such as X-24, X-33, X-34, X-43, etc. In fact, the European Union is also conducting intensive research. The European Space Agency is promoting the European space plane program and developing a rocket-based air-breathing combined cycle engine for it."

"The Polar Bear is a long-established aerospace technology power, and has particularly strong technical accumulation in the scramjet engines used in aerospace planes. In the 70s and 80s, the Rainbow Mechanical Design Bureau launched the 'Needle' and 'Rainbow-2' verification aircraft programs to conduct preliminary research on hypersonic aerospace vehicles."

"On the contrary, China is relatively slow in this regard. If we work together, we can catch up with and surpass our competitors such as the United States and the Polar Bear more quickly."

Qian Junfeng further persuaded Cao Yang from the side.

After all, to develop an aerospace plane, there are too many technical barriers to such a product.

The reason why China Aerospace Science and Technology Corporation and AVIC have discussed the project for a long time but have not officially launched it is because there are too many problems that have not been resolved.

For example, in terms of materials, since the space shuttle needs to enter and exit the atmosphere many times, a large amount of aerodynamic heating will be generated each time due to the intense friction with the air. Especially when returning and re-entering the atmosphere at hypersonic speed, aerodynamic heating will cause its surface to reach extremely high temperatures.

The temperature at the nose is about 1800℃, the temperature at the leading edges of the wings and tail is about 1460℃, the lower surface of the fuselage is about 980℃, and the upper surface is about 760℃.

Therefore, a lightweight, high-performance, reusable thermal protection system is necessary.

Another issue is engine development.

The flight range of the aerospace plane is from the atmosphere to the outside of the atmosphere, with speeds ranging from 0 to 25 Mach.

Such a large span and change in working environment is impossible for any single type of existing engine to cope with, making the development of a brand new engine for the aerospace plane the key to the entire project.

There are various other issues such as aerodynamic design, any one of which is daunting and there is no hope of resolution in the short term.

"The tripartite cooperation can indeed speed up the development of this project. We at Venusstar Technology are very willing to work with AVIC and CASIC to develop air-conditioned aircraft."

"At that time, we can set up a project team in Chang'an, Yangcheng, the capital and other places respectively, and promote each small project in accordance with the overall needs of the project."

"For example, the design of the appearance and aerodynamic analysis of aerospace vehicles can be done in Guangzhou, where our newly built super wind tunnel happens to be."

"For example, research related to airframe structure and material selection can be done in Chang'an City. Nanshan Carbon Fiber's headquarters is now located there, which can give full play to their advantages."

“Some projects related to human-machine engineering interaction can be considered to be placed in the imperial capital to give full play to the advantages of AVIC and aerospace technology.”

"As for the engine, we can further decompose its R&D tasks by combining the information of Nanshan Engine, AVIC and China Aerospace Science and Technology Corporation."

Zhao Tianling and Qian Junfeng have already said this, so Cao Yang naturally would not refuse.

However, although he is cooperating with the two companies on aerospace vehicle projects, Cao Yang still hopes that the ultimate initiative will be in the hands of Nanshan-based companies.

After all, the other party has just started discussing this product, while Venustech has officially launched related research and development.

The best way now is to let both companies cooperate with Venustech's development needs, provide relevant personnel and technical support, and ultimately bring out the products as soon as possible.

Qian Junfeng and Zhao Tianling could understand this point.

Anyway, we have cooperated before. For example, the H-20 project has been handed over to Venustech to lead.

Even many technical personnel in Venusstar Technology jumped from AVIC or Aerospace Science and Technology. The communication and precautions among people are not that great.

"I agree with Mr. Cao's idea. If we want the aerospace vehicle project to be implemented as soon as possible, we must maximize the advantages of our three companies."

"Now Venusstar Technology has already started to move forward, and we at AVIC will fully cooperate."

Zhao Tianling was the first to stand up and express his attitude.

He had just said so much about the necessity of cooperation. It would be obviously inappropriate for him to raise a bunch of opinions right after Cao Yang agreed.

Qian Junfeng had a similar idea and immediately stated that Aerospace Science and Technology also supported Cao Yang's arrangement.

This product, which will have a significant impact on the world in the future, quickly accelerated its progress.

Of course, people outside don’t know this information.

……

When it comes to aerospace vehicle projects, whether it is Venusstar Technology, AVIC or CASIC, they all attach great importance to confidentiality.

However, the ultra-high-speed wind tunnel laboratory developed by Venustech has been reported to the outside world on a large scale.

For professionals, it is still very easy to draw some conclusions from this laboratory.

After all, the only things that need this kind of wind tunnel are either hypersonic missiles or hypersonic aircraft, nothing else.

No matter which product it is, it is a very sensitive issue for China's competitors.

For example, in the United States, John found David from Boeing to discuss the things behind the hypersonic wind tunnel laboratory developed by Venustech.

"Although there is no specific source of intelligence, according to the information we have, Venusstar Technology is already developing several types of missiles and even anti-missile systems."

"This time, the hypersonic laboratory is likely to have some relationship with this project."

Although Venusstar Technology has done a good job of keeping secrets, many things cannot possibly leave no trace at all.

Besides, Venustech alone has over 100,000 employees, and this number is still increasing rapidly.

In this case, it is impossible to keep some information completely confidential.

So it is only natural that the organization behind John can find out some information.

"Venus Technology has strong technical capabilities in rockets and satellites. It is not surprising that it can produce advanced missiles."

"But I'm worried that they will not only develop a few missiles, but also come up with some products that no one has imagined at all, which will be very troublesome."

David has dealt with Venustech a lot over the years and has suffered a lot from it.

Many things that people thought were impossible before were eventually accomplished by Venustech.

If he hadn't experienced it himself, he would never have believed it.

"Your concern is not without reason. I heard that Venusstar is now fully engaged in researching various military products."

"They used to advertise themselves as a private enterprise producing civilian products, but now they don't advertise like that much anymore."

John felt a little overwhelmed.

The situation is becoming increasingly difficult to deal with.

"If the Morningstar 9 is modified, it can become an intercontinental ballistic missile."

"With a few modifications to the Chang'e space station, it can become a mobile space military base."

"Not to mention the Black Hawk and Apache-like products they are currently developing, which have nothing to do with civilian use."

“We should not be misled by their propaganda.”

David never thought that Venustech was a civilian enterprise.

Just like Boeing, it has never been a civilian enterprise.

Even though Boeing’s most famous products are various civilian aircraft, it is essentially one of the top military-industrial complexes in the United States.

That is the confidence that America has in dominating the world.

"David, Venustech is doing more and more things. Do you have any way to curb their development?"

Talking about other things can only vent your resentment, but it cannot solve the problem.

John came here today with the purpose of solving the problem.

"If you want to curb the development of Venusstar Technology, you have to curb the development of China, otherwise it will be impossible to curb it."

"In the past few years, we have divided our focus very widely. We have been desperately involved in various things around the world."

"I think we need to make appropriate choices in the future and focus our attention on the Asia-Pacific region."

"We need to think of ways to cause trouble for China so that they don't have as much energy to focus on economic development."

"As long as the economic strength is weak, all kinds of problems will arise. Wasn't it the same thing that brought down the polar bears back then?"

Regarding the question raised by John, David actually discussed it with people within Boeing for a long time.

I'm just taking this opportunity to say it now.

Of course, Boeing will certainly not rely solely on John as a voice channel, it also has its own spokespersons.

In fact, Boeing is not the only one doing this. Companies such as Lockheed Martin are also doing similar things.

Only by focusing America's attention on the most threatening areas can their relevant departments realize that many of America's military equipment needs to be updated.

It is also necessary to continuously increase the military expenditures allocated by relevant departments.

Ultimately, a large portion of these costs will fall into the pocket of Boeing, the military-industrial giant.

……

"Grotin, this time when I go to exchange ideas with Venusstar Technology, I want to add an exchange project, which is to use their wind tunnel laboratory to conduct some modeling research."

Dmitri is now paying close attention to the developments of Venusstar Technologies. He vaguely feels that Venusstar Technologies will become a leading company in the global aerospace field in the future.

There is no harm in grasping the other party's development rhythm in a timely manner for Polar Bear United Rocket and Space Corporation.

So he naturally knew about the newly built hypersonic wind tunnel laboratory of Venusstar Technology.

Although it seems that many countries have wind tunnels, the difference between wind tunnel laboratories and laboratories is very large.

Just like many countries can produce drones, but the difference between drones is not that big.

The wind tunnel laboratory of Venusstar Technology can be said to be the most advanced in the world, without a doubt.

One of the development focuses of Polar Bear United Rocket and Space Corporation in recent years has been the development of various hypersonic cruise missiles and ballistic missiles.

At present, the technology they have accumulated in this area is quite good.

However, Dmitri feels that there is still room for improvement in the missile's appearance design and aerodynamic layout.

After all, for some things, it is definitely not enough to rely solely on computer software simulation.

The simulation parameter designs of those software are derived and sorted out based on actual data.

If similar experiments have never actually been carried out, then the information produced by the simulation software can only be used as a reference.

"You want to use the other party's wind tunnel laboratory to carry out missile research?"

Grogin was not stupid and immediately knew what Dmitri's purpose was.

A large part of the funds allocated to them by the relevant departments of the Polar Bears are used to research missiles and rockets, which are also closely related.

If we fail to produce satisfactory results in these two areas, it will affect our ability to obtain funding in the future.

So Grotin also attaches great importance to this business.

"Yes, I think looking around the world, the only company that can help us with the research of hypersonic missiles is Venustech."

Demetrius gave his reply with certainty.

"Let's not talk about whether the other party is willing to cooperate and what the conditions are."

"If we just cooperate with each other, won't the information about the missiles be leaked out?"

Confidentiality is a very important issue in military-industrial units and it cannot be overemphasized.

So Grogin didn't want to suffer any loss in this place.

"It's just information about appearance. Even if Venusstar Technology knew about it, it wouldn't have a big impact."

"They already have a lot of experience in this area, and they may not necessarily be willing to learn from us."

When Dmitri said this, Grogin's face darkened.

China learned its missile technology from the polar bear. It can be said that the other party has always been China’s apprentice.

But now it seems that the apprentice’s level is improving very quickly, and the master is about to starve to death!

However, that was the truth, so Grotin had no reason to object.

Besides, when faced with two evils, choose the lesser one.
