"High-pressure compressor, intermediate bearing, high-pressure rotor bearing, double-walled combustion chamber, tile sheet heat dissipation, vector nozzle ......"

"No, I can't. There are too many details. ”

Single room in a dormitory. Li Xiu rubbed his swollen head, feeling a little tired.

Since there is a project to build a fighter, Li Xiu also tried to analyze it.

But halfway through the process, he gave up.

He was able to exchange engine drawings and redraw them in more than half a month.

The structure of the entire fighter is much more difficult to draw than an engine.

This system is not something that can be drawn directly after being exchanged.

There are structural diagrams, and it is not possible to start drawing immediately. I also want him to learn to understand the knowledge inside.

What's more, the number of details in an entire aircraft composition is too large.

If you use paper, you have to count tons of it. Not to mention a year, it is estimated that it will take two or three years to draw it all by yourself.

Scientific researchers are not dry food, and in his previous life, he overcame all difficulties and solved all kinds of problems, so that one industrial pearl lost its gold content. What has always been checked and balanced is only high-precision core technology.

In this life, it must be possible, and after overcoming the big problem of the engine, it is estimated that if you can't use yourself, you can directly get the fighter out.

"There are drawings of large ducted engines, and small ducted engines can be designed according to their core structure. In this way, the J-20 should be able to see the light of day a few years earlier. ”

The difference in other aspects or details between the large and small ducted turbofan engines is mainly due to the working conditions and requirements.

Li Xiu took out the drawings of the large ducted engine, and changed the ducted ratio according to the structure, and the small ducted engine could be developed.

The core technology of the engine is solved, and the rest of the technical difficulties will not cause much hindrance to the researchers.

gave up participating, and Li Xiu remembered the 'black technology equipment' given to Li Ao a few days ago.

These equipment are all practical equipment on the scale of a synthetic brigade.

In his philosophy, the synthetic brigade is not only a superposition on the scale of the synthetic battalion, but also an evolution and supplement in the combat form.

The main battle equipment is enough.

Other equipment must also be installed.

Now, he's just planting the seed.

……………………

Inside an ornately decorated office. A valian-looking commander hung a thick cigar and looked at the papers on the table with a slight mockery.

Next to him, the thick-eyebrow commander looked much more serious.

Facing the always heroic and confident Colonel Hulk, Commander Lille with thick eyebrows asked in a tone that pleased Colonel Hulk.

“…… So, Colonel Hulk, you mean there will be hidden dangers in the plane? ”

"If they want to save money to find a woolly bear, that's it."

Colonel Hulk bared his white teeth and smiled, "Our intelligence system has known this for a long time, hasn't it?" ”

"And we're going to ruin their deal?" Lille asked.

"Why? They're just a bunch of poor ghosts, and they won't be rich. ”

Hulk retorted.

Lille was noncommittal, and at the same time, regretted Huaxia's choice.

For a lower price, Huaxia chose to buy the all31NS engine of the woolly bear.

The thrust-to-weight ratio of this engine with great defects can reach 7, but the overall proportion of the fighter is only one, that is, in the case of lagging behind the West in material technology, in order to improve the thrust-to-weight ratio of all31ns, Red Bear does not hesitate to sacrifice the reliability of its support system and lubrication system to reduce weight.

Although it is very in line with the design concept of Red Bear Lida Brick Fly, its design flaws are irreparable.

The failure rate of Type 3 turbofan engines will be greatly increased, especially according to the information of their intelligence bureau, in Maoxiong, there have been eighteen shaft break accidents alone.

And the life is very short, their F100 engine has a two-stage low-pressure turbo with only a three-stage fan, while the All31N has only a one-stage low-pressure turbo. This results in an all31ns lifetime of only nine hundred hours. Compared to their whopping 4,000-hour lifespan, it's nothing short of rotten.

There is no doubt that this is a rather chicken rib third-generation fighter engine.

Suddenly, the telegram on the table ticked and ticked.

Colonel Hulk's face immediately became serious.

Immediately called the cipher officer.

After half an hour of decipherment by the ciphers, the contents of the telegram were quickly cracked.

"Huaxia has suspended the purchase of all31n. Are they ready to buy our F100-GE? ”

Colonel Hulk gave a strange expression.

Although it is said that the current focus of their mold country is on the hairy bear, it does not mean that they want to make Huaxia better.

The Moldy Nation has always wanted Huaxia to get out of their technological control.

Therefore, from time to time, something will be revealed for Huaxia to buy, so that Huaxia has neither the money to engage in its own research and development, nor its own technology.

However, it doesn't mean that they really want to sell the good stuff to the rabbits.

The F100-G, that is, the F16 engine, is already a very mature engine.

Colonel Hulk showed a hint of regret.

Buying their F100-G engine, at least very stable. There are no minor problems.

Of course, if their hearts are a little darker, they can also play some hands. It's not their business, though.

"I think maybe they've found a hidden danger."

Hulk Colonel Road.

"So are we going to raise our selling price? Or outright refuse? ”

On the other side, Lille asked worriedly.

"We don't count." Hulk glanced at Lear, then said, "Why refuse?" Isn't it good to have them as our wallet? Maybe we'll give them some discounts. Lille. You need to learn a little bit about this, and a lot of times, we have to leave them a little bit to live. ”

"It's like a beast, if you kill it at the beginning, it will explode with ferocity, but if you feed it poisoned food, it will slowly become your prey."

"That's what you said." Lille hurriedly said: "So, is it possible for them to develop their own engines?" ”

"Self-developed engines? Turbojet engines? If they want to develop their own, then we can rest easy. ”

Hulk sneered, disdainful.

"With the current technology of the Chinese people, how can they build an engine that can compete with us?"

"What if they continue to study? I think it may be a solution to the problem once and for all. ”

Hulk was very confident, but he was not blind, although he was sarcastic, he still said: "However, Huaxia is not Ah San, they have a saying called 'make a fortune with a muffled voice'." This situation is dangerous. We need to keep abreast of their movements. ”

"Yes"

The atmosphere is still relaxed.

Because it has suffered losses many times, this time, Huaxia has done an excellent job of secrecy.

……………………

PS: Forget it, let's fast forward. This plot is too difficult to handle.

There's a lot of professional knowledge, and I don't understand it
