Chapter 105 JF12 Hypersonic Shock Tunnel

Nighttime at a large hotel in Nanning, Guangxi Province.

Outside the window, neon lights of various GG brands flashed, and the humid wind, carrying the rustling sound of palm leaves, slipped in through the window cracks.

Williams, the first representative of the American observation team, turned on an anti-eavesdropping device, watched the indicator light turn from red to green, opened his shielded laptop, and encrypted a video call to China.

"Hey Williams, how did the public exercise you watched today go?"

The video call connected, and a white figure appeared on the computer screen.

Through the camera, you can see the bright morning sunlight outside the window behind the other person, and several cups of freshly brewed, still steaming, coffee on the office table.

"Mr. Smith, well, I don't know how to describe it."

Williams thought for a moment and said seriously, "Very strong, yet very weak."

Their new drone is invincible on the battlefield; no soldier can stop this drone from flying missiles right in their face.

However, for our country and for our strategic security, it is very weak and poses no threat whatsoever.

According to their country's official statement, this is a piece of equipment specifically designed to strengthen the army and further enhance its combat capabilities.

That's indeed true, just as they said; it's a very good piece of army equipment.

However, it is not a weapon capable of offensive operations, as its maximum range is only a few tens of kilometers.

In addition, I analyzed it with the team this afternoon.

It may have some impact on the security of our overseas bases, but the extent of the impact is still uncertain.

We observed them during the day and found that apart from selling a batch of drones to Pakistan, they haven't made many sales to other countries.

However, they opened up the civilian market for this drone, mainly using it for aerial photography...

Williams gave a detailed report on the exercises he had observed that day, the arms sales situation, the civilian drone market, and the analysis from his observation team.

"With a range of tens of kilometers, except for the specially made fiber optic version and the version using laser communication, the others are not resistant to electronic interference and communication suppression, and the payload is 1 to 3 kilograms..."

On the other side of the video.

Smith discussed it with the advisors and staff around him and nodded in agreement, saying, "Compared to military equipment, this is indeed more like a civilian product. It's great for aerial photography. The only highlight is that it can carry bombs and fly them at soldiers' faces."

If this were used against our soldiers at overseas bases, it would indeed be a problem.

"Yes, sir!"

Williams added, "They're quite fast, reaching speeds of over 200 kilometers per hour, making it very difficult for soldiers to dodge them."

This is a very good and powerful piece of equipment for small countries and regions, and it also poses a significant threat to our base. I suggest that we consider restricting its use...

"Williams, why the restrictions?"

Smith smiled and said, "It's a standard civilian product, but we're going to restrict it just because it can be used to carry bombs."

People in the desert have been using gas cylinders as artillery shells since 07. We can't possibly restrict gas cylinders too, can we?

We have no reason to impose restrictions now, unless we break off relations, but that's not a decision we can make.

As for the potential threats to our overseas bases in the future... if that really happens.

Our legislators would recommend equipping each base with cable nets, microwave jamming devices, and close-in weapon systems, as well as providing each soldier with a shotgun and individual communication suppression equipment…”

"I see."

A flicker of realization and delight crossed Williams' eyes: "Mr. Smith, today we also encountered Desert Camel purchasing drones here, and they indicated they would also purchase them from us. I have already sent the relevant information to your email."

"Yes, I saw it. That was handled very well. I'll have someone follow up on it..."

Smith nodded approvingly: "I heard they even included a company of spoiled rich kids in this public exercise?"

"Yes."

Williams nodded: "One of the main figures is the grandson of the No.1 in the Guangzhou region, another is the son of the chief engineer of Chengdu Aircraft Industry Group who designed the drone, and the rest are the children of their officers or core researchers at various levels."

Their official explanation is that this arrangement is to cultivate future teams.

But after some initial investigation, we found that this drone combat system was incompatible with their army's existing system. In the end, it was the family members and children who developed the corresponding combat system, so they participated in the exercise together..."

"oh."

Smith sat up straight immediately: "Have you investigated the personal histories of these two people? Are there any special circumstances?"

"We had our undercover agents investigate before the exercise, and we just got the results today."

Williams looked at a document next to him again: "There are no special circumstances. He is a sixteen-year-old in the third year of junior high school. He is quite active, likes all kinds of sports, has excellent grades, and is highly regarded by his teachers. He is influenced by his family to learn various military and training tactics."

"A twelve-year-old still in elementary school, with a rather lazy personality, grew up in the Chengdu Aircraft Industry Group's residential area, likes playing games, had consistently poor grades in elementary school, received mediocre evaluations from teachers, but is very skilled at operating drones..."

"Sixteen years old, twelve years old... At this age, they're still in elementary or middle school. Hmm, no need to investigate further. It's most likely due to both reasons, but they're just reluctant to admit the second one."

Smith tapped the table: "Williams, this exercise is done. You all go to Chengdu immediately."

Some time ago, it seemed that Chengdu Aircraft Industry Group (CAC) had a new aircraft test, and then the 606 and 624 teams suddenly gathered at CAC.

You should investigate this matter thoroughly. If necessary, you can request external assistance to probe the situation.

Over the past few months, we've lost several small teams there, and several lines of espionage have been uncovered. I suspect we might have been set up as a sting operation...

"Yes, Mr. Smith, we'll go tomorrow."

Nine o'clock at night.

Zhang Xiali changed into her work clothes, looked at Lin Dong who had just finished showering and was sitting in the living room with his laptop, and gently instructed him.

"Xiao Dong, there's something I need to take care of at the base. You should go to sleep soon, don't stay up too late."

"Okay, Mom, be careful."

Lin Dong replied, and used the mouse and keyboard to adjust a part of the original Hot Spicy variable ramjet engine blueprints, turning it into the engine components for the Longsword missile.

Then, add notes on why this improvement was made, what theories were involved, and the general verification process.

"Done."

"If I feed him this way, Godfather should be able to learn and understand without any problems, right?"

Lin Dong saved the blueprints, encrypted them, and then connected to a secure email address on the internal network to send the blueprints to Wang Xingguo.

After waiting a while, the drawings were successfully sent.

Lin Dong shut down all software and background programs on his computer, took out the USB drive given to him by Wang Xingguo, and plugged it into his laptop.

Di-

A scanning circle popped up. After waiting for about ten seconds to confirm that there was no problem, a password box and a countdown timer popped up in the center of the screen.

"This secure USB drive is a hassle; it requires system and location verification every time it's used."

Lin Dong muttered to himself, quickly entered the password, and pressed the Enter key.

Suddenly, a document popped up.

The document is not very long, only a few hundred lines long, and also includes seven or eight actual photos of the new Hot Spicy rocket undergoing wind tunnel testing.

"Subsonic speeds of Mach 0.8, Mach 1, Mach 1.8, Mach 2.3, Mach 2.8, and Mach 3.5 three times each... and once each of Mach 5, Mach 6, Mach 7.3, and Mach 8.6?"

"I don't recall applying for a hypersonic test. Is this an upgrade for me?"

"And has China's first hypersonic shock tunnel already been completed?"

Lin Dong quickly scanned the speed corresponding to the test data, and a look of astonishment and shock suddenly flashed in his eyes.

If he remembers correctly, the only wind tunnel in China capable of conducting hypersonic tests at speeds of Mach 5 to Mach 10 is the JF12 shock tunnel.

It was this hypersonic wind tunnel that opened the door to China's hypersonic field and laid the foundation for various waverider missiles and hypersonic aircraft.

Ten years later, the Americans also wanted to develop hypersonic aircraft. They offered to spend tens of millions of dollars just to have China blow-dry the JF12 shock tunnel for them once, but China refused. It can be said to be one of the most important national projects.

He just hadn't expected it.

My brand new, hot account has somehow managed to catch such a lucky break.

He didn't have much of an impression of when the JF12 wind tunnel was built.

Moreover, this is a top-secret project with no information from the outside world. Asking even a few more questions could raise the suspicion of the security department.

He avoided any trouble and directly applied to Lin Weiliang for a test at intermediate speeds.

The plan is to obtain data on intermediate supersonic speeds and then derive the data for hypersonic speeds.

Although the data derived by myself is not as precise as the data obtained from actually blowing a wind tunnel because the Navier-Stokes equations do not have an exact solution, it is still possible to complete the overall design.

Once we have news about the JF12 hypersonic wind tunnel test, we can test it again to verify and adjust the details. Then the shape of the fuselage will be pretty much finalized.

But to his surprise, before he could even apply, the wind tunnel testing team upgraded his package...

"Was it the godfather or the father who helped with the registration?"

"Did the wind tunnel testing team see that it was a classified application from Chengdu Aircraft Industry Group, and it was a hypersonic design? Since the wind tunnel itself also needed to be tested, they simply decided to use the new 'Hot Spicy' rocket for testing?"

Two guesses flashed through Lin Dong's mind, but after thinking about them without reaching a conclusion, he simply stopped thinking about them.

Looking at the wind tunnel data in the document, I couldn't help but feel uneasy.

"With this hypersonic wind tunnel data, the fuselage design can be finalized in just two months..."

"The fuselage design is way ahead of schedule... but the engine development is seriously lagging behind!"

Originally, his plan was to develop the fuselage design and engine design of the new Hot Air simultaneously.

Once he completes the fuselage design, the supercharger engine design will also be nearing completion, allowing for simultaneous production, assembly, and takeoff.

But now.

A single hypersonic wind tunnel test, which significantly accelerated the design of his fuselage, severely delayed the engine development...
