Chapter 220 Variable Cycle Engine? Let's Talk About It First!
While recalling the contents of the movie, Jiang Chen sighed and said that the crew had put in a lot of effort when designing the J-20C.
A fighter can take off and land vertically, which means that it does not need a long runway, and can take off and land in a small space, which can greatly improve the flexibility of deployment.
And can fully expand the geographical scope of its mission!
In order to complete this setting, Jiang Chen designed the tail nozzle and the lift fan to deflect at a large angle, so that when taking off, he can adjust the direction of the nozzle of the engine to make it vertically downward.
In this way, through the lift fan device at the front, the aircraft can be lifted up one by one! When landing, the aircraft is also lifted by the front and rear devices to reduce the speed.
But the problem is, the design is designed like this, if the engine problem is not solved, can it fly? Not to mention the fuel consumption of ordinary turbofan engines, and the thermal cycle mode is fixed, and the speed cannot be raised at all.
"MOSS, does the turbofan engine only have one working mode?" Jiang Chen now regards MOSS as a new generation of point-and-read machine, and he can just ask MOSS directly for ordinary questions.
[Yes, whether it is a turbofan engine or a turbojet engine, the design structure is fixed from the beginning, so it can only have the best performance within a limited range of flight routes. 】
[This is true of the engines in the current five-generation fighter jets. 】
[Administrator, do you really want to develop a variable cycle engine? 】
"It's necessary, when the time comes, we will add another fifth-generation aircraft to Longguo, Dorafeng."
"Furthermore, the J-20C is very practical. If the development is successful, then our team will be afraid of others when all J-20Cs are deployed?"
The idea was good, but Jiang Chen began to worry about the materials.
There is no material base for making fighter jets.
This thing, if it is used on a fighter jet, ordinary materials will definitely not work.
Thinking of this, Jiang Chen decided to contact Academician Liu, the chief designer of the J-20. After all, he is a professional manufacturer of fighter jets, so there should be no shortage of materials.
Academician Liu was surprised when he received Jiang Chen's call.
"Academician Jiang, are you really going to build a fighter jet yourself?"
Jiang Chen was afraid of scaring the academician, so he said: "The crew needs to use it for filming, so I have to build a special one for filming!"
"Oh, that's right, but if it is manufactured according to the standard of a real machine, the cost will be high."
Academician Liu was right, but Jiang Chen couldn't help it.
How can he learn technology if he can't complete the task?
Although the system is a broken system, the things I learned are all real!
Helpless Jiang Chen had no choice but to say: "Our director likes to use real props to shoot, saying that it will have texture."
Jiang Chen didn't plan to tell Academician Liu that he was going to build a new generation of fifth-generation aircraft, otherwise he would have to explain it to all kinds of people for a long time.
After explaining it, others may not believe him, so I simply made it up first.
"You directors really worked hard to respond to the 'Wukong Project', but this is true. How about it, why don't you come to our factory, where everything is available, materials and manpower."
Jiang Chen's eyes lit up when he heard Academician Liu, and he thought it would be convenient to go to Shu Fei's place.
There are basically all kinds of aviation materials there. If not, you can find a way to make them according to the system prompts. Unlike staying in the base, you may not be able to find the machine.
The matter was settled in this way, Jiang Chen asked Yan Zhengqian to explain the situation: "Mr. Yan, the matter is like this, if the expenses incurred when I make props, will the country reimburse me?"
After a few seconds of emptying his mind, Yan Zhenggan said: "It can be reimbursed, after all, the Wandering Planet project is now a national project, and reimbursement is a small problem.
"Academician Jiang, you don't really want to build an airplane this time, do you?"
If it is true, it is indeed too magical.
Seeing Yan Zhenggan's worried eyes, Jiang Chen secretly thought it was funny.
Fortunately, I didn't tell the other party the truth about this time, otherwise Yan Zhengqian must have thought that he had lost his mind.
"Don't worry, Mr. Yan, airplanes are not so easy to manufacture."
Yan Zhengqian nodded in agreement.
There is no doubt that Yan Zhenggan must be with him when he goes to Shufei.
After the two chatted about the itinerary for a while, MOSS suddenly said——
[Administrator, Professor Lu wants to talk to you. 】
Jiang Chen reacted for a moment, and then realized that the professor Lu mentioned by MOSS was the one who studied biological self-repairing waterproof coatings with him before.
"Okay, let her come to Chief Yan's office to find me." After Jiang Chen and Professor Lu researched the paint, they handed over the matter of the research institute to Professor Lu.
She must have something important to tell herself this time.
Sure enough, after Professor Lu arrived, he started talking as soon as he saw Jiang Chen.
"Academician Jiang, people from the science and technology team have received news that they have already stockpiled the raw materials for bio-waterproof coatings. According to the current reserves, they can produce bio-waterproof coatings for 20 years."
20 years?
How much is that.
These raw materials are not in short supply now, why are the people in the technology group so nervous?
Could it be that the people in the technology group are going to do something new?
Jiang Chen turned his eyes, looked at Yan Zhenggan and asked, "Mr. Yan, do you know about this?"
"I have heard a little bit about the purpose of storing raw materials, academician Jiang, do you know?"
Jiang Chen thought for a while, and guessed: "Is this going to be announced?"
"That's right, academician Jiang, your scientific research achievements are obvious to all, but some technologies are related to national defense and cannot be released, such as biological waterproof coatings and holographic projection technology can be made public."
"This will not only demonstrate our country's scientific and technological strength, but also make the common people more confident in scientific research. Therefore, after careful consideration, the leaders above decided to disclose the scientific research results of biological waterproof coatings first."
It turns out that once the technology is made public, the relevant raw materials will definitely rise for the purpose of experiments or for the purpose of hoarding goods and selling them at high prices.
Jiang Chen looked at Yan Zhengqian in surprise, he never thought that Longuo would allow him to disclose his technology.
As soon as the technology of bio-waterproof coatings is made public, orders from Snowflakes follow.
Not only can he make money, but even Longguo can enrich the treasury.
This is extremely beneficial to him or Long Guo.
If we want to vigorously develop science and technology, we cannot do without money.
"Then is it already offline for production?" Jiang Chen asked.
"Yes, it has passed the laboratory test, the pilot test stage, and the production test, and it has been secretly used in some units."
"Now the leaders want to fully open the paint market, so that more people can know the existence of this paint."
"Now I want to ask Academician Jiang, which method he wants to use to make it public." Professor Lu looked at Jiang Chen's silence and said in a timely manner.
Fuck?
It's up to me to decide?
Do you want to ask me for my opinion on everything?
Although Jiang Chen is well-versed in technology, he doesn't know much about these things.
He doesn't know what choices he has now, how to choose?
No, I have to maintain my identity and pretend to be timid.
"Hey, what about Professor Lu's opinion?"
