Technological power starts with upgrading lenses

After two days of wild play at the Aoying test flight base, Kang Chi successfully obtained a fixed-wing and helicopter pilot's license. With this driver's license, he will be able to legally drive Yinhe around in the future.

The test of the Turbofan 30 is still going on, but because this engine performed so well in all aspects after passing the first round of testing, its grade was directly raised to the highest level, and it was directly sent to Mianyang to start the third round. high-altitude platform testing.

After all, the second round of testing was actually a bit rough.

For example, the bird impact test is just like the car crash test. It will definitely damage the engine. The only difference is the size of the bird it can withstand.

If it can't resist even the smallest bird, it means that the engine is not up to standard, and the reason must be found out and redesigned and improved.

And such testing means that many prototypes are needed. If it is not particularly urgent, you can test it while building it, and improve it while testing it.

But after the level is increased, this kind of test, which will definitely damage the engine, can be left to the later stage. This will also give Datang Heavy Industry more time to build the test machine.

Six members of the technical team of Datang Heavy Industries followed the engine to Mianyang, and the rest returned to Dongyang by transport plane yesterday afternoon.

After looking at Yinhe being loaded into the transport plane, Kang Chi suddenly became playful again. He turned to Chen Hai and asked, "I want to experience supersonic flight. Can you apply for it for me?"

Chen Hai was stunned immediately.

"I can't fly a jet..."

"I didn't say I wanted to take your seat. You can just ask Li Xiangnan to take me back to Dongyang. Don't worry, Datang Heavy Industries will pay for all the expenses!"

"..."

Is this a question of whose fault it is to spend the money? !

Seeing Chen Hai's speechless expression, Kang Chi added confidently: "Our company will develop a small bypass ratio engine next. I want to experience an aircraft with this engine first. Is this a good reason?"

"..."

Chen Hai had no choice but to sigh helplessly.

"Wait for me here for a while."

After Chen Hai finished speaking, he directly went to the general manager of the base and applied.

Although they all knew that Kang Chi was definitely doing this to satisfy his curiosity and had nothing to do with building an engine.

But as long as Mr. Kang's demands are not too excessive, can they still disappoint him?

So the application was quickly approved.

When Kang Chi followed Li Xiangnan and Shen Ye to the hangar and saw the two-seater J20 inside, his eyes suddenly lit up.

So handsome!

This visual shock is much stronger than the photos!

"This is the ultimate man's toy!"

"..."

Seeing Kang Chi who was as excited as a child, the two of them immediately laughed.

Li Xiangnan has become somewhat immune to Kang Chi's state in the past two days.

Although it is a bit exaggerated, Kang Chi like this makes them feel more real.

Otherwise, it will always give them the illusion and sense of distance that this guy is not human...

The ground crew helped Kang Chi put on his flight suit and helmet, helped him sit in the back seat, made sure that the seat belt and mask were on, and then closed the cabin door.

When starting the plane, Li Xiangnan couldn't help but warned again: "Remember, don't touch any button by mistake."

"Well, I promise to just sit and enjoy the scenery!"

Li Xiangnan nodded. In fact, the weapons of this aircraft were all removed. Even if Kang Chi pressed the missile launch button, it would be useless. The main reason was that he was afraid that he would press the skydiving button...

Under the guidance of the ground staff, the plane quickly taxied to the runway. The transport plane carrying Yinhe in front had just taken off, and it was their turn next.

"Mr. Kang, take a seat!"

After receiving permission from the tower to take off, Li Xiangnan said hello and began to gradually increase the throttle.

However, considering that it was Kang Chi's first time flying in a fighter jet, he flew extremely carefully and did not dare to accelerate too violently. The original minimum take-off distance was more than 200 meters, but he just slid for more than 600 meters before flying. .

Even so, the strong pushing feeling still made Kang Chi feel very excited.

It’s great that Malaysia is pushing small machines!

The thrust of fighter jet engines with small bypass ratio, especially the turbofan 15 with afterburner, has basically reached its limit. The new technology that can be added to it is mainly to change the bypass ratio, which allows the fighter to cruise at cruising speed. It is more fuel-efficient, increases combat radius and ammunition load.

Moreover, in order to pursue stealth performance, the engines of fighter jets are built into the fuselage. Therefore, this duct change technology cannot be changed to an external duct, but must be changed to an internal duct.

Due to changes in the outer duct, the fuselage may have to be redesigned, which wastes valuable space in the fuselage.

However, the design difficulty of changing the inner duct is obviously more difficult than that of changing the outer duct. If the afterburner still adopts the traditional rear design, it may be simpler.

But if you want to have a front afterburner and shorten the length and weight of the engine like the turbofan 30, it means putting a variable inner duct on the fire, and it will be grilled both inside and outside...

The design difficulty and material requirements suddenly became higher.

Kang Chi didn't know if PG01 could bear it, so he could only let Yan Hui and the others try to build it first.

"Mr. Kang, do you feel okay?"

"Well, okay, what was the maximum acceleration just now?"

"2G."

"Would you like me to experience 4 or 5G?"

"No, the superior requires that it can only be controlled at 2G."

"It's okay, my body can handle it."

"Sorry, this is a request from my superiors. I can't break the rules. You just need to experience it properly. There is no need to joke with your body... We are about to enter supersonic speed."

As soon as Li Xiangnan finished speaking, Kang Chi felt that the roar of the air around the plane began to obviously get louder, pressure waves began to form, and the fuselage of the plane began to tremble slightly. When the plane finally broke through Mach 1, the wind noise disappeared immediately. , only the noise from the engine through the fuselage can be heard.

But at this time, you still can't take off the sound-isolating headphones. After all, the noise of the aircraft engine is not vegetarian...

Watching the clouds passing quickly outside the window, it seemed that time was blurring due to the accelerated speed. This dizzying experience made Kang Chi feel a little sad.

Only technology can bring this unprecedented experience to mankind...

Liaodong Province, Sanshan Shipyard.

In Project 004 Department, after Ren Zhou received the news that Chief Shen came to see him, he immediately put down the work at hand and returned to the office from the aircraft carrier.

After hearing the footsteps, Chief Shen, who was contemplating with his eyes closed, immediately opened his eyes and looked at Ren Zhou.

"Didn't it disturb your work?"

"It's okay. Today we are mainly testing the lift. It's not a big problem. I don't have to keep an eye on it."

"That's good. Everything went well in the audition, right?"

"It went very smoothly." After Ren Zhou took off his coat, he replaced Chief Shen's tea cup with a pot of hot tea, and then he took a sip of tea and continued, "We are currently following the time plan, maybe this time it will be faster. That one is slower, but the overall situation is still ideal... You came here specially, you won't come to rush the progress again, right?"

"Did I push you so hard?"

"It's not there, you just don't feel it yourself."

Chief Shen suddenly smiled: "No wonder you all met me like a mouse meets a cat... Well, no kidding, I came here mainly for something that Dr. Kang mentioned to me the day before yesterday. thing."

"Dr. Kang? Kang Chi?"

"right."

Ren Zhou immediately became energetic.

"What did he say?"

"He wants you to help him design a drone carrier."

Drone aircraft carrier! ? ?

Ren Zhou was stunned immediately.
