Inside the Institute of Frontier Science and Technology.
Everyone was attentive, listening to Jiang Chen's explanation.
"The bypass ratio data also seems to be somewhat abnormal."
"We should increase it a little, and the thrust performance can be improved a lot!"
“The fan intake air and bypass air are both less efficient and the combustion efficiency is insufficient, resulting in a large increase in fuel consumption!”
"And here."
Jiang Chen was staring closely at the data on the screen, constantly making various corrections!
After all, this aircraft engine was changed from a small duct to a large duct, so it is normal to have various problems.
There are many aspects of the problem that have not been taken into account!
Fuel economy and endurance are the most critical things for a transport aircraft, not thrust performance, etc.!
But on the previous EPD-20 engine, it was just the opposite!
Fighters need mobility, but transport planes don't!
"Okay, Mr. Jiang!!"
"There is indeed a problem in this area, and it needs to be corrected."
"The aspect of fuel economy should be given special consideration. After all, this is not a fighter jet!"
"The fan surface can be enlarged and the intake air circulation can be increased so that the efficiency of the combustion chamber will be higher!"
Several academicians of the Academy of Aviation suddenly nodded and said, obviously very much agreeing with this statement.
Fighter engines and transport aircraft engines have completely different needs.
What transport aircraft pursue is transportation efficiency, endurance, carrying capacity, etc., followed by speed!
A transport plane that consumes a lot of fuel is no less than a bird with its wings broken off!
No matter how good the paper performance is, it does not have much practical ability at all. It must be considered comprehensively!
And the transport aircraft they want to develop this time will surpass the C-5, and even surpass the An-225!
Don’t be careless!
"H-20 also has to consider this issue."
"But if stealth is needed, then the H-20 must have a small tunnel!"
"It is estimated that this engine will need to be significantly modified before it is used on the H-20!"
"This is difficult"
Lu Yuanhang suddenly got a headache when he thought about this problem. Their real challenge was this!
Only flat bombers and fighter jets, if the surface area of the fuselage is reduced as much as possible, can't be detected by radar!
The flat shape means that an aero engine with a small bypass is required!
The H-20 requires not only a small duct, but also sufficient load capacity and endurance. In this case, it also needs to save fuel!
Under this major change, the difficulty is no less than re-research and development!
While everyone was still discussing various technical points.
Suddenly.
A R&D staff member walked in with a data report in his hand!
He said to Jiang Chen and others:
"General Engineer Jiang's first batch of 6 J-20s have all been upgraded!"
"After flight testing by Captain Li and other elite pilots!"
"The performance data is all normal and correct. It meets the standards!"
There was strong joy and excitement in his tone!
The words just fell!
"Great, the J-20 has finally been upgraded!"
"The performance is all normal? Wouldn't it be possible for it to be installed on the front line soon?"
"It's almost there. It should be ready to be delivered to the Air Force at any time!"
"You don't know, Air Force veteran Tian is almost living in Dean Lin's office during this period!"
Several academicians of the Aviation Academy suddenly became happy and began to communicate with each other.
Not to mention the Air Force, even they have been looking forward to this day for a long time!
This is the first batch of upgraded J-20 fighter jets, and all of them have dual new engines instead of single engines!
After all, the single-shot performance improvement is not that big!
It is better to directly use the dual-engine J-20, or even directly defeat the F22 fighter equipped with XA-100!
Once the test is completed, it means it can be delivered to the Air Force’s front-line troops for use!
However.
Just when they were happy about it.
Jiang Chen frowned, he was a little dissatisfied and said to Lu Yuanhang:
"Why are there only 6 upgraded?"
"Isn't this quantity too small? Our production speed shouldn't be that slow, right?"
"After such a long time, only a few J-20s can be installed? What's going on?"
"Is there a problem in any part of our process?"
He has been busy with various research and development, so the installation and production matters have always been carried out by Lu Yuanhang!
It was originally estimated that there should be at least 20 J-20s in the first batch this time, but in the end there were only 6?
You must know that the J-20 has three aircraft in a formation, which can only be equipped with two formations.
Even a squadron needs 12 fighter sorties. What are these 6 aircraft used for?
If we continue to upgrade at this speed, it will probably take years to replace all China's J-20s!
Not to mention that there are also J-15, J-10C and other fighter jets. At this rate, it will take years and months to complete the installation and upgrade?
"There is nothing we can do about it, Mr. Jiang!"
"The main reason is that the current material output is really not enough. We have only been able to produce more than ten engines this month!"
"So we can only install and upgrade 6 J-20s. This is already the ultimate efficiency!"
Lu Yuanhang shook his head helplessly and explained.
It’s not that their production speed is too slow, but that the material output and supply cannot keep up!
None of the three new alloy materials currently developed can be manufactured in large quantities.
Even if it is just the easiest ultra-high temperature wear-resistant alloy.
Production cost is not a problem, after all, one gram of ultra-high temperature wear-resistant alloy only costs 4 pieces/g!
The material cost of an engine is only 8 million at best! (Based on 2 tons.)
But no matter what, the output of materials is only so much!
Think of this.
"That's a problem!"
"I will optimize the production equipment later. We must speed up mass production!"
“And our Academy of Sciences is no longer responsible for producing materials, that’s too slow!”
"Let the various research institutes below carry out preliminary research and development and production work!"
After Jiang Chen thought for a moment, he gave the order directly.
Let the various research institutes under the Institute of Materials Engineering start work simultaneously, so that production can be quickly expanded!
Not only is the new engine of the J-20 needed, but the electromagnetic weapons on the other side also need ultra-high temperature wear-resistant alloys!
When an electromagnetic weapon fires a bullet, steel cannot withstand the high temperature that bursts out instantly!
"Yes!" Lu Yuanhang and others responded in unison.
After a while, all the questions were answered.
Jiang Chen was sitting on the table in the research institute, tapping his fingers on the table.
Obviously he was deep in thought at this time.
"The high-performance version of Gundam Mecha"
"We need an upgraded version of high-density solid-state batteries, which may not be that easy to make yet!"
"At the research institute, it is estimated that it will take some time to complete the energy battery upgrade technology."
"The rest of the research and development projects are progressing normally!"
He whispered secretly in his heart, constantly thinking about the next research and development plan and how to proceed!
At present, almost all research and development projects seem to have stalled, which he is not used to.
At this time.
Zhao Xiu walked up to him and asked.
"General Engineer Jiang has almost finished developing the exoskeleton armor!"
"The research and development progress of the military version of Gundam Mecha is very smooth so far."
"I feel like the design will be finalized soon."
"Only the two final difficulties of sensing and transmission are left!"
His tone was full of excitement!
After all, he has the theoretical basis provided by Jiang Chen, as well as a complete set of related drawings!
And they all have finished Gundam mechas, so their research and development speed has naturally increased by leaps and bounds!
Not only will the exoskeleton armor be developed soon, but even the military version of the Gundam Mecha will be finalized soon!
Hear this.
Suddenly, Jiang Chen seemed to have remembered something, and a look of joy appeared on his face!
This is not just because the development of the military version of Gundam Mecha is going smoothly.
He just remembered something crucial, something he hadn't had time to develop yet!
"I have thought about what the next step of research and development of the institute should be!"
"There is something I haven't started developing yet!"
Jiang Chen's eyes lit up and he spoke quickly.
He has already thought of what his next research and development plan will be!
This is exactly the technology he got from the beginning!
However, since Jiang Chen has been busy with various research matters during this period, Jiang Chen never thought of it!
Taking advantage of this opportunity, we can develop it directly!
"Chief Engineer Jiang, the new research and development direction of our research institute??"
"What kind of technology is that? I've never heard you mention it before?"
Zhao Xiu's tone was confused and he said slowly for a while.
He didn't remember that he had mentioned this matter before, and there was no memory at all!
Hear what he said.
"I think we can start developing Gundam!!" Jiang Chen said word by word.
"Developing Gundam? Aren't we always developing it?"
"Is it a Gundam mecha with better performance? That's not a new project!"
“It’s just an upgrade.”
Zhao Xiu was even more confused. Could it be that he had misunderstood?
Even the fully upgraded military version of Gundam Mecha is still the original research and development direction!
only.
Staring at Zhao Xiu and everyone present!
"No, it's not a Gundam Mecha, nor is it a military version of a Gundam Mecha!"
"What we want to develop is a giant Gundam!!"
"A real Gundam, a Gundam mecha that's more than ten or twenty meters tall!"
Jiang Chen shook his head, his tone full of excitement, his eyes shining.
He just finished speaking! !
In an instant!
Zhao Xiu's eyes widened, looking completely unbelievable!
Giant Gundam?
The entire institute suddenly became silent, as if you could hear a pin drop!
Whether they are academicians or ordinary researchers, they all look stunned!
It was as if he was wondering if he was hallucinating! !
"hiss"
"Chief Engineer Jiang, do you want to develop Gundam??"
"That kind of giant Gundam that's over ten or twenty meters tall??"
Good guy, they even wondered if Jiang Chen was joking!
