Siheyuan: I eat melons while doing scientific research

Chapter 1144 Gao Zhendong is itchy (three chapters today, one chapter will be published first)
This car was sent to the Third Factory, mainly because it was not very convenient to enter and exit the alley.

Gao Zhendong jumped onto the car excitedly and touched here and there.

He can drive. After taking the college entrance examination in his previous life, he went to get a driver's license. It took him two years on and off to get it, and it was a C1 license, which allowed him to drive a manual transmission car.

Then, the main function of a driver's license is to deduct points. Except for driving when traveling with senior students, I seldom drive the car at other times. It is probably another kind of "two tanks of gas a year".

Seeing Gao Zhendong like this, the comrades from Beijing Automobile Factory were very happy, but the hearts of other comrades were in their throats. Could it be that this guy wanted to take a walk around?

There’s an old saying that goes – What you fear is bound to come to you!

Gao Zhendong kept touching around in the car, but he didn't feel satisfied, so he decided to do it himself!
This type of car is positioned as an entry-level national car. It is impossible for all of them to have automatic transmission these days, and even the AMT semi-automatic that Gao Zhendong suggested is impossible. However, the one Gao Zhendong has here is undoubtedly a top-of-the-line model with full configuration, so it naturally has no shortage of AMT and other things.

This is good news for Gao Zhendong. If it is a car that needs to pull the choke, he can't drive it with his skills, but this is a semi-automatic car! It is basically in Gao Zhendong's comfort zone. C1? What C1? I am actually a C2 driver, understand?
When the comrades on internal security at the Third Branch Factory saw Gao Zhendong's expression, they knew the situation was not good.

Gao Zhendong stretched out his hand and said, "Give me the key!"

When the comrades from the Beijing Automobile Factory were happily taking out the money, they were held down by the security comrades from the Third Branch Factory.

"Chief Engineer Gao, you don't have a driver's license, right? This is a violation of discipline." All comrades knew that Chief Engineer Gao attached great importance to discipline, so this was the only way to deal with it.

Gao Zhendong was dumbfounded when he heard this. Oh shit, I really don’t have this thing.

"Well, I also drove a car when I was on the battlefield. Do I still need that thing?" Gao Zhendong decided to cheat. As for whether he had driven a car on the battlefield, no one knew.

"Chief Engineer Gao, you have returned to the local area, the discipline is different now." The comrades in charge of internal security are very smart, and they immediately found a reason. As for whether Chief Engineer Gao had driven a car in the army or not, or whether he drove well, it didn't matter, anyway, you didn't have a driver's license in the local area.

Gao Zhendong was very disappointed. He touched his head and sat down on the passenger seat. Given the size of the car, this movement was quite difficult.

"Come, take me around the factory."

The current No. 3 Rolling Mill is a large factory with a factory road that is wide enough for strolling.

This request was no problem. The comrade who drove the GAZ-69 for Gao Zhendong stepped into the driver's seat, and under the guidance of the comrades from the Beijing Automobile Factory, he quickly started the car and drove forward.

Not only Gao Zhendong was happy with this run, but even the driver himself felt extremely comfortable. After all, compared with a sedan whose technology was actually at the level of the 69s and 80s, the GAZ-90 was completely beaten in all aspects except for its off-road capability.

The driver felt happier than Gao Zhendong when he was driving.

"How do you feel about this car?" Gao Zhendong asked with a smile.

"It's easy to drive, comfortable, and more powerful than the GAZ-69."

This is for sure. Even a castrated three-cylinder engine is much smoother than the GAZ-69 engine. So happiness is achieved through comparison.

"Let me try it twice." Gao Zhendong's hands were itching again.

"No, boss. You're asking me to make a mistake." The driver felt happy, but he was not confused and he refused to give in.

Gao Zhendong hesitated to speak and finally said nothing.

The car drove back to the parking lot of the Third Factory, and Gao Zhendong jumped out of the car: "This car will be my daily car from now on. It is more comfortable than the GAZ-69 and is more fuel-efficient."

As for when off-roading is needed, the comrade in charge of driving will naturally make arrangements.

After saying this, he turned to the security guard at the third factory and said, "Can you help me find out how to get a driver's license?"

I still don’t believe it!

"We must not let him get his driver's license!" This statement came from the Defense Working Committee. As for how to implement this matter, naturally there are comrades to handle it.

After getting back home, Gao Zhendong was still immersed in the excitement of the new car. Looking at Lou Xiaoe who was busy, Gao Zhendong suddenly had an idea.

"Xiao'e, why don't you take some time to get a driver's license."

Gao Zhendong had more or less figured it out. He probably had no chance of getting a driver's license, or it was very difficult. Although he was confident in his learning ability, he could not prevent the referee from cheating. Well, that's OK. I'll let my wife drive. That should be fine.

Lou Xiao'e was dumbfounded: "Driver's license? Why should I get that? Don't you have a driver at home? There is also a driver at your workplace."

Gao Zhendong shook his head: "That's so boring. There are already new cars being produced in China. If you learn to drive, we can buy one and you can take me out to play. That would be wonderful."

Lou Xiao'e is a soft-hearted person. When she heard Gao Zhendong's envisioned bright future, her eyes lit up. I'll take Zhendong out to play... just thinking about it makes her feel so happy.

As for why Gao Zhendong didn't take the driving test himself, Lou Xiao'e had never thought about it at all.

Lou Xiao'e nodded her head like a woodpecker: "Yes, yes, yes, that's good, I'll go take one!"

It is not easy to get a driver's license these days, and even ordinary people have no such way. However, Lou Xiao'e did not consider this, after all, she is not an ordinary person.

As for whether Lou Xiao'e's idea of ​​getting a driver's license can be realized, who knows.

At the Northeast Aircraft Manufacturing Plant, a MiG-21 with a slightly strange wing shape landed steadily on the ground.

This is an original MiG-21, but if there is any difference, it is that its wings have a distinct two-stage swept angle.

The mission of this aircraft is to test this somewhat strange-looking wing shape.

The comrades on the ground rushed forward, some hung up ladders, some received the test pilot, and some comrades began to open some cabin doors and connect data cables to the aviation plugs exposed inside the cabin doors.

They were downloading data from onboard test equipment.

The data is still being downloaded, and the comrade in charge of the wing modification has already greeted the test pilot who has just got off the plane. The data can reflect the actual process, but as the top of the pilot pyramid - the test pilot, he can naturally also feel the flight quality intuitively from the flight, and he also has first-hand feedback data from the onboard instruments.

"Old Li, how does it feel to fly?"

Test pilot Lao Li had just taken off his helmet. In the late November weather, his forehead was covered with sweat and a comrade on the ground staff quickly put a fur hat on his head. The flight helmet was uncomfortable to wear, but if he took it off, his head might get cold, so he had to put on the hat quickly.

Lao Li's face was full of excitement: "Good! Very good! Although the top speed is slightly affected, the impact is not significant. This airfoil still retains the performance of the large swept delta wing in high-speed flight to a great extent."

Although the wind tunnel test results show that the double delta wing basically retains the high-speed performance of the large swept delta wing, and the maximum speed can even reach Mach 2.2 without causing wingtip stall and wing elastic deformation problems, the wind tunnel is a wind tunnel and reality is reality.

Moreover, this only verifies the extreme flight speed of the double delta wing, but there is not much evidence for the increase in thrust demand for the double delta wing. Of course, theoretical calculations show that the airfoil and two-stage sweep angle proposed by Comrade Gao Zhendong do not have much effect on high-speed flight, but as I said, theoretical calculations are just theoretical calculations, and those who understand fluid mechanics will understand.

Now that it has flown down from the air, it has been proven that this wing shape does not have much impact on the high-speed performance, and the comrades responsible for modifying the wing are more than half relieved.

At least the high-speed performance is not lost, which is enough. After all, as long as this is not a problem, it is equivalent to having obtained a larger wing fuel tank, which is of great benefit to the range. They have calculated that the change of this double delta wing and the larger wing fuel tank can increase the range by 10% to 40% at different altitudes and combat profiles.

This is a remarkable number!
The high-speed performance is not affected too much, and the range is directly improved. Who wouldn’t be happy?
As for the slight impact, we still have the engine thrust increase improvements waiting.

Chief Engineer Gao's suggestion to modify the airfoil at the meeting can now be said to be completely successful, and nothing else is needed.

But science is science, and benefits are benefits. You can't just give them up if you want to. The benefits brought by the double delta wing are obviously more than just that.

"Moreover, compared to the original MiG, the aerodynamic focus of this aircraft has changed, making it easier to operate..."

Although this had been anticipated in the calculations, the comrades in charge of modifying the wing profile were still very happy when the test pilot said this himself. As we all know, one of the criticisms of the MiG-21 is its mediocre handling performance, and they did not expect that they could solve this problem at the same time.

In fact, what they don’t know is that the change of aerodynamic focus is the original purpose of the birth of the double delta wing on the MiG-21 model, and the starting point of all this comes from the impact of the super heavy air-to-air missile on the aircraft when it was launched.

As for other benefits, they were actually incidental. Of course, these benefits gradually became the main demands, which was an unexpected result.

So many advantages have been proven and the comrades are all grinning from ear to ear, but the story is not over yet.

"And during the flight, I could clearly feel that the aircraft's agility and low-altitude maneuverability have been greatly enhanced..."
