"Yes!" Jiang Yan Hai agreed directly without being pretentious.
The reason is very simple. Other engines, such as the WS series engine, have long been finalized. What was done before was just the replacement of materials.
The tests that these engines should be done have been done for a long time. As for other detailed tests, they are not important, at least not as important as the ones in Jiang Yan Hai's hands.
"But there is something I have to explain first." Jiang Yan Hai said.
"Say." Several old professors looked at him.
"The entire engine design adopts another design plan, so when using conventional aviation fuel, its maximum thrust is only 177 kilonewtons, and its intermediate thrust is only 152 kilonewtons. Its current data is achieved with a new type of aviation fuel that I specially prepared."
"New aviation fuel?" Several old professors were stunned. Although the 177 kilonewtons and 152 kilonewtons mentioned by Jiang Yan Hai were actually amazing enough, from what they had seen before, no one wanted these numbers.
"Is this aviation fuel expensive?" one of the professors immediately asked.
"It's not expensive. It's about the same price as the current aviation fuel. The price per ton is estimated to be only a few hundred yuan. The main reason is that it requires new additives and different formulas, so if it is used, fighter jets may need to be refueled separately from the previous ones." Jiang Yan Hai explained.
All the professors immediately breathed a sigh of relief when they heard that this was just the problem and the cost had not increased much.
"This is not a problem. Just pay attention to the logistics. This is completely out of proportion to the combat effectiveness it can form. This small flaw can be tolerated." Another professor immediately said.
"Then there are no other problems." Jiang Yan Hai nodded.
"I heard that you want to design your own fighter jet?" Professor Qian remembered something again and asked again.
"Yes, I want to design a stealth fighter myself. In fact, from the beginning, to the size and specifications of the engine, performance parameters, including aviation fuel, I designed it for this new fighter." Jiang Yan Hai nodded directly.
All the professors had some unbelievable feelings, although all designers of fighter jets first give the performance data of a fighter jet, and then find ways to design and complete it.
However, when the data of this fighter jet was given at the beginning of the design, it was based on the actual situation, taking into account the overall domestic manufacturing level, research and development level, etc., and then gave the performance parameters before designing.
This was the first time they heard that someone first specified the abnormal data of this stealth fighter, and then in turn developed the engine, and even developed new formula materials and new aviation fuel, just to achieve the data of this stealth fighter.
The key is... from the data of this engine, you can understand how abnormal the data of the stealth fighter this guy originally planned to develop was.
Could it be that... this is the difference between geniuses and ordinary people designing things?
"Well, boy, let me take the liberty to ask, what is the maximum speed of the stealth engine you designed?" Old Liu over there couldn't hold it back. He is a professional fighter designer. This guy wants to fly a stealth fighter, and it is probably a two-engine heavy stealth fighter.
A heavy stealth fighter propelled by a single engine with a thrust of 27 tons... and a twin engine with a thrust of 54 tons. How could it be so slow?
"The limit speed is Mach 4! The limit speed of regular cruising is Mach 3." Jiang Yan Hai didn't hide it either.
"Pfft..." Old Liu choked again.
Regular cruising speed is Mach 3??? Boy, you really dare to think!
The problem is, this guy even built an engine for this number. Based on this thrust, if the weight of the fighter he designed is similar to the J20, there will be no problem in reaching this speed.
"Boy, do you know? Reaching this speed is not just a problem with the engine." Old Liu couldn't help but speak again. This is his essential job, and of course he knows what the point is.
"I know that thermal barrier is a huge problem, so I developed a new type of super invisible Composite Materials! According to my idea, about 70% of the material of the body will be composed of this Composite Materials, so that its stealth ability is almost difficult to detect even Microwave Radar."
"In addition, its empty weight can be reduced to about 15 tons while maintaining a volume similar to that of the J20. But the strength of its material allows it to withstand high temperatures of hundreds of degrees Celsius due to friction with air."
"But this kind of Composite Materials is a bit difficult to make, and the cost is probably a bit high." Jiang Yan Hai knows that this is an opportunity. Each of these old professors here can speak very effectively.
All professors. "..." Everyone's expressions were a little weird.
"Have you already done it?" Old Liu's tone was weird. Now he didn't dare to look down on this kid, because everything this kid said so far has come true!
"Yeah! There are two types in total, one is magnetic loss Stealth Coating, and the other is structural stealth Composite Materials. Paint is easy to say, but this kind of Composite Materials is difficult." Jiang Yan Hai nodded directly.
"You kid... no wonder you want to see the internal circuit design of J20 with me, okay... you are awesome! In this way, if you really have the design drawings, if you don't mind, we old guys can help you." Old Liu spoke directly.
"This... how can this be possible?" Jiang Yan Hai was startled. Are you kidding? One of them can be said to be at the level of a master in academic terms. Let them attack him?
Then he must not be sprayed to death by people in the circle?!
"Why not?" Professor Li asked.
"You are all highly respected seniors..." Jiang Yan Hai spoke immediately.
But before he finished speaking, he was directly interrupted by Professor Li.
"Boy, there is a specialization in the art, there is a priority in learning the Tao, there is no age in learning, and those who are masters come first. If we are three people, I will always be my teacher. You haven't heard these words, haven't you?"
"I've heard of it." Jiang Yan Hai took a deep breath before speaking.
"Okay, no need to talk nonsense, we 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, and we old guys still have some face in the industry... By the way, have you decided on a name for the fighter jet you are planning to design?" Professor Li asked.
"Get up, Phantom." Jiang Yan Hai said seriously.
"What a name! Then you are the chief designer of Phantom Fighter Jet! Don't be embarrassed. We can still command some people. Since you are confident, we will work on it together. We will know if it works or not. You have courage, determination, and action. Don't we old guys still care about some reputation?" Professor Li's old voice is loud and clear.
Jiang Yan Hai is silent, what is the backbone of the republic?! That's it!
