Chapter 865 Backbone

"Yes!" Jiang Yanhai agreed immediately, he was not hypocritical.

The reason is very simple. Other engines, the WS series engines, should have been finalized long ago, and what was done before was the replacement of materials.

The tests that should be done for these engines have been done a long time ago. As for some other detailed tests, it is not important, at least not as important as the one in Jiang Yanhai's hands.

"But there is one thing I have to explain first." Jiang Yanhai said.

"You said." Several old professors looked at him.

"The design of the entire engine adopts another design scheme, so when it uses conventional ordinary aviation fuel, the maximum thrust is only 177 kN, and the intermediate thrust is only 152 kN, and its current data is in line with my special A new type of aviation fuel that was formulated to achieve the effect."

"New type of aviation fuel?" Several old professors were stunned. Although Jiang Yanhai said 177 kN and 152 kN were actually quite amazing, but from what they saw before, no one wanted this number. want.

"Is this jet fuel expensive?" one of the professors asked immediately.

"It's not expensive. It's actually similar to the current aviation fuel price. The price of one ton of up and down is estimated to be only a few hundred yuan. The main reason is that it needs new additives and different formulas, so if it is used, the fighter jets will be refueled at that time. It may be necessary to separate from the previous one." Jiang Yanhai explained.

Hearing that this was the only problem and that the cost did not increase much, all the professors immediately breathed a sigh of relief.

"This is not a problem, as long as you pay attention to the logistics, it is not proportional to the combat power it can form. This small flaw can be tolerated." Another professor said immediately.

"Then there are no other problems." Jiang Yanhai nodded.

"I heard that you want to design a fighter jet yourself?" Professor Qian asked again after remembering something.

"Yes, I want to design a stealth fighter myself. In fact, from the very beginning, I designed the engine's size, performance parameters, and aviation fuel for this new fighter." Jiang Yanhai nodded directly.

All the professors have some incredible feeling, although all the design of the fighter jet is given the performance data of a fighter, and then find a way to design and complete it.

However, when the data of this fighter was given at the beginning of the design, it was also based on the actual situation, taking into account the overall domestic manufacturing level, research and development level, etc., and then giving the performance parameters, and then designing.

This is the first time they heard that someone first stipulated the abnormal data of this stealth fighter, and then in order to achieve such data, they developed engines, and even developed new formula materials, new aviation fuel, just to achieve this. Data on stealth fighters.

The key is... From the data of this engine, you can understand how perverted the data of the stealth fighter that this kid originally planned to develop.

Could it be that... this is the difference between geniuses and ordinary people designing things?

"That, boy, let me take the liberty to ask, what is the maximum speed of this stealth engine you are planning to design?" Mr. Liu over there couldn't hold back. He is a professional designer of fighter jets. This kid wants to get on a stealth fighter jet. And it is estimated to be a twin-engine heavy stealth fighter.

A single-engine thrust of 27 tons... a heavy stealth fighter propelled by a dual-engine 54-ton thrust, how could this be slow.

"The limit speed is Mach 4! The conventional cruise limit speed is Mach 3." Jiang Yanhai did not hide it.

"Pfft..." Liu Lao choked again.

Normal cruising speed is Mach 3? ? ? Boy, how dare you think!

The problem is, this kid has even come up with an engine for this number. According to this thrust, if the weight of the fighter he designed is similar to that of the J20, there is no problem in reaching this speed.

"Kid, do you know? Reaching this speed is not just a matter of the engine." Liu Lao couldn't help but speak again. This is his essential job, and of course he knows what the point is.

"I know that the thermal barrier is a huge problem, so I developed a new type of super invisible composite material myself! According to my idea, about 70% of the material of the body will be composed of this composite material, so that it The stealth capability is almost impossible for metric wave radar to detect."

"In addition, its empty weight can be reduced to about 15 tons while its volume is similar to that of J20. However, the strength of its material can allow it to withstand the high temperature of hundreds of degrees Celsius rubbing against air."

"However, the difficulty of making this kind of composite material is a bit high, and the estimated cost is a bit high." Jiang Yanhai knew that this was an opportunity. One of these old professors here counts one, and their words are very useful.

All professors: "..." Everyone's expressions were a little weird.

"You've already figured it out?" Liu Lao's tone was weird, and now he doesn't dare to despise this kid, because everything this kid has said so far has been fulfilled!

"Yeah! There are two kinds in total, one is magnetic lossy invisible paint, and the other is structural invisible composite material. Paint is easy to say, but this kind of composite material is difficult." Jiang Yanhai nodded directly.

"You boy... No wonder you want to see the internal circuit design of J20 with me, okay... You are amazing! In this way, if you really have a design drawing, if you don't mind, we old guys will help you." Liu Lao directly just opened his mouth.

"This... how can this be." Jiang Yanhai was taken aback, what a joke, there is one among them, one can be said to be at the level of the ancestors in terms of academics, let them fight for him?

Then you shouldn't be sprayed to death by people in the circle? !

"Why not?" Professor Li asked back.

"You are all highly respected seniors..." Jiang Yanhai said immediately.

It's just that he was interrupted by Professor Li before he finished speaking.

"Boy, there are specialties in the arts, and there is precedence in hearing about the Tao. There is no age in learning. The master is the first. The three must have my teacher. Have you heard these words?"

"I heard it." Jiang Yanhai took a deep breath, and then said.

"Okay, then there's no need to talk nonsense, we people will help you, since you are confident, then hand over everything you have designed so far to us. Designing a fighter jet is a systematic project. The guy still has some face in the industry... By the way, have you named the fighter you are going to design?" Professor Li asked.

"Get up, Phantom." Jiang Yanhai said seriously.

"Good name! Then you are the chief designer of this Phantom fighter! There's nothing to be embarrassed about, we can still command some people, since you are confident, let's get it out together, can it work? You have the courage, determination, and action, don't we old guys still care about some reputation?" Professor Li's old voice was loud and clear.

Jiang Yanhai was silent, what is the backbone of the republic? ! This is!
