Dongyang, Pangu base.

Although Chen Hai's Yun-20 went first, the speed was much slower than the J-20 sitting on Kangchi.

In less than an hour, Kangchi was the first to arrive at the Pangu base from the Eagle test flight base, spanning nearly 2,000 kilometers in the middle.

This efficiency is so high that Kangchi can't help but want to buy one as a long-distance vehicle......

However, it is still a bit extravagant to use a high-cost fifth-generation aircraft as a means of transportation, and the leader may not refuse because he favors him and pays for it himself, but he has to have a scale in his heart and knows what it means to be pampered and arrogant.

If you have time in the future, you can consider cooperating with COMAC to develop a small supersonic passenger aircraft, maybe with the development of the times and the economy, this kind of thing that is not suitable for the market is now there a market?

After saying goodbye to Li Xiangnan, Kang Chi walked straight into the Pangu base, and the guards saluted him directly after seeing that it was him, and then immediately felt the familiar feeling that was in full swing.

At present, except for Laboratory 06, which belongs to Kangchi's absolutely private space, and no one can enter without his permission, half of the other areas are temporarily idle, and the rest of the place is carrying out the production of turbofan 30.

However, after the completion of Datang Heavy Industries' Luzhou No. 2 Plant next month, this production line that has just been rushed out is estimated to be moved again, and some mass production equipment may be added to meet the production capacity requirements of turbofan-30.

"Mr. Kang, welcome back."

Yan Hui, who received the news in advance, was already waiting for him at the door with several technical backbones, and they all came back early yesterday.

After saying hello to them with a smile, Kangchi observed the production situation in the base.

"Has the second one been built?"

"Not yet, I guess it's almost tomorrow."

"Hmm...... Wait for the 20 to send Yinhe and Chen Hai back, and let them wait for a day, and send the second engine over tomorrow by the way, and conduct the second round of testing at the same time. ”

"Okay."

After confirming that the base was in normal condition, the group soon came to the R&D conference room, and Kangchi began to assign them the next tasks.

"The production of turbofan-30 will be in charge of Dr. Fang Qiang next, including the transfer of the production line next month, and we will come back to Dongyang after Luzhou is on the right track."

Hearing that he was going to work in the field for a period of time, Fang Qiang's heart couldn't help but secretly complain, but he had not been sent by Kangchi once or twice in the past few years, and his psychological endurance was no longer what it used to be.

I especially remember that when Kangchi asked him to go to Gangcheng to build a single crystal furnace, he put the overall situation of the country first, so that Fang Qiang couldn't find a reason to refuse.

What's more, this time I still build a turbofan 30, if you don't want to go, it is estimated that it will be a bigger hat to buckle down......

Therefore, he only hesitated for a moment, and then nodded directly: "I'm fine." ”

"Well, yes, yes, Director Fang is now more and more of a general in charge, I hope everyone can learn from Director Fang in the future, the company's demand for talents like Dr. Fang is still very high."

Kang Chi's praise at this time, coupled with the envious eyes of everyone, made Fang Qiang almost unable to find the north......

Compared with Mr. Kang's high evaluation, how old is the business trip in the field!?

"Well, another task is about the research and development plan of the turbofan-25."

"Turbofan 25?" Yan Hui was a little puzzled, "I remember that the detonation engine seems to be in the front, right?" ”

"The project was cancelled." After Kang Chi explained a little vaguely, he then said to Yan Hui, "I only give you a general requirement for the development of turbofan 25, and I mainly leave it to you to complete it yourself, are you sure?" ”

"Well, there is still a certainty, after all, you have taught us the core technology of the turbofan 30, but the time is ...... Surely you can't do it so fast. ”

"It's okay, this project is not in a hurry, and I just thought about it carefully, and I think that there are not many things that can really improve the small duct than the engine."

After Kang Chi finished speaking, he walked to the front of the whiteboard, drew two concentric circles, pointed to the outer circle and said: "When I just took the plane, I suddenly found that I actually fell into a technical misunderstanding, that is, I was too persistent and superstitious to change the duct technology. ”

"But for the engine with a small bypass ratio, as long as there is a full-bypass afterburner, it can enter the vortex state of 0 bypass ratio at any time, and the bypass ratio only determines its speed and fuel consumption in the cruising state."

"Therefore, we don't need the technology of changing the duct at all for the small bypass than the engine, we only need to use the performance of PG01 material to apply the front technology of the afterburner and the reverse thrust technology."

Yan Hui nodded, if the change duct is removed, the difficulty of improvement will obviously be reduced a lot.

But soon he frowned again and said, "But the reverse thrust seems to be a little difficult to achieve." After all, the engines of fighter jets are all built into the fuselage......"

"So I had a bold idea." Kangchi pulled out a hard drive from his bag, "This is the J-15 blueprint I want to come." ”

"If we don't think of the engine and the fuselage as two separate parts, but the fuselage as a part of the engine...... What will happen? ”

Think of the fuselage as a part of the engine?

They quickly realized the meaning of Kangchi's words, and then their expressions were stunned.

What does Kangchi mean by integrating the baffle door into the fuselage of the aircraft?

This means that the aircraft becomes a ...... that can be flexibly vented in all directions Motor?

The idea......

It's crazy!

But who dictates that airplanes can only be jetted behind?

If the materials allow, the idea of Kangchi is really feasible!

In fact, the vector engine is to change the tail exhaust direction of the engine, so that the aircraft can make some incredible super-maneuverable maneuvers, and even carry out vertical take-off and landing actions.

But even the most advanced vector engine can deflect the direction of the tail airflow by 90 degrees at most.

And if this crazy assumption of Kangchi can be realized, not to mention the vertical take-off and landing and the incredible super-maneuverable maneuverability, it may even be able to fly bricks vigorously, directly making the plane fly sideways and backwards!

Imagine when an enemy has just locked on to you from behind, and you suddenly jet forward and right, completing the sudden braking and left flash......

The offensive and defensive situation has been transformed in an instant!

Just ask this kind of flexibility, who can stand it?

However, this design has very high requirements for the strength structure of the aircraft, and it is a huge test for the pilot's body.

It is estimated that it must be made into a drone to maximize its extreme performance.

Of course, unmanned is Kangchi's medium and long-term plan, before the communication technology is completed, try to develop a traditional manned aircraft, to verify the idea of more practical.

After understanding Kangchi's train of thought, the researchers present were suddenly a little excited.

People engaged in scientific research usually have a fanatical passion for this kind of principle that does not shatter the three views, but it is subversive, so as soon as the meeting ended, Yan Hui couldn't wait to take over the hard drive and began to discuss and study fiercely with everyone.

But Fang Qiang was uncomfortable.

Seeing that everyone was working on this thing, just listening to it made people want to build it immediately, and he had to run around to assemble the turbofan for 30 ......

This gap is too big!

Fang Qiang couldn't help but look up at Kangchi,

As a result, Kangchi has already flashed......
