Jiang Chen looked at the stranger calmly. He looked about thirty years old, with a thin figure, but his eyes were shining, and he looked like a top shot.
Jiang Chen said nothing, and the stranger also smiled and said nothing.
Jiang Chen was confused.
You came all the way here without talking. Brother, are you here just for fun?
Academician Liu probably also felt that the atmosphere was a bit strange, and he quickly said: "This is Xiang Yang, the project manager of COMAC. Xiao Xiang, this is the Academician Jiang I told you."
Xiang Yang's eyes flashed with joy and he said, "Hello, Academician Jiang, I didn't expect to finally see you!"
After speaking, Xiang Yang held Jiang Chen's hand, with such excitement on his face that Jiang Chen mistakenly thought he had met a fanatical fan.
After the embarrassed Jiang Chen said hello to the other party, he waited for the other party to say something.
"Academician Jiang, it's like this. The J-20C you developed has been spread among the top management of our aviation industry. Now the leaders of the capital hope that our civil aviation can also make breakthrough progress."
"This is a good thing." Jiang Chen commented, not realizing at all that this matter had anything to do with him.
"Without the civil aviation manufacturing industry, we may not be beaten, but we can't escape being slaughtered."
Listening to Jiang Chen's words, Xiang Yang repeatedly expressed his agreement.
"Yes, Boeing and Airbus stole a lot of money from us before, but there was nothing we could do if we didn't buy them. Now, under the leadership of Academician Jiang, fighter jets and drones have been developed."
"We are worried that Boeing and Airbus will raise the price of civil aviation aircraft and make us take advantage of them."
hiss--
Jiang Chen took a slight breath.
I thought to myself that I haven't thought of this level yet.
I have raised the level of domestic fighter jets and drones. Will Yingjiang be happy?
Maybe it will cause harm in other ways.
In the entire aviation manufacturing industry, the manufacturing of civil aviation aircraft requires the integration of various advanced technologies. Only when a country's industrial development reaches a certain level can it be possible to develop its own civil aviation aircraft.
Moreover, once a civil aviation passenger aircraft is developed, it will also have a driving effect on the entire country's industry.
Now that they cannot build large aircraft, they will inevitably be strangled by companies such as Boeing and Airbus.
But why did Xiang Yang come all the way here to tell him this?
Jiang Chen had a bad feeling in his heart.
Sure enough, the other party came up with the next step: "I hope Academician Jiang can help us."
Tsk, this favor is not something you can just ask for help.
I built a fighter jet before. Compared with civilian passenger aircraft, they have some similarities, but they are also very different.
In terms of flight performance, fighter jets need higher climb rates, greater maneuverability and faster speeds to survive and perform missions in special times.
Passenger aircraft focus on comfort and economy, and are usually designed for smoother and more efficient cruising flight functions.
According to Jiang Chen's experience in building fighter jets, there is really no confidence in letting him build a passenger jet.
But the only thing that's certain is that he can still help with the engine.
"The engine currently used by the J-20C is Blue Star's first variable-cycle engine. This engine currently has a maximum afterburning thrust of 30 tons, but the thrust of a passenger aircraft like the Boeing 777 is about 52 tons."
"The thrust gap is not very big. We can find ways to improve it, but it will take time." Although Jiang Chen obtained the technology from the second part of Wandering Planet, he only had the technology of the J-20C in terms of aviation.
Although learning relevant techniques can achieve the effect of analogy, it still takes time to touch.
Building a passenger plane is not something that can be solved in a flash.
That one engine is not enough. Can't we install a few more variable cycle engines?
It really doesn’t work.
Civilian aircraft are generally subsonic commercial airliners, and more consideration is given to fuel costs and service life at subsonic speeds. If a few more oil-hungry variable-cycle engines are mounted, not many people will be able to fly.
Therefore, it must be changed to an engine with a high bypass ratio, high pressure ratio, and high temperature ratio, which can save a small amount of money.
The key thing is how to change this, Jiang Chen doesn't have a clue yet.
In order not to expose his current lack of knowledge about civil aviation aircraft, Jiang Chen asked MOSS to give Xiang Yang a small part of the basic information on variable cycle engines, and asked him to go back and study it first.
After Xiang Yang left, Jiang Chen dug out the system.
At this time, the system's voice suddenly came to mind.
[Congratulations on completing the mission: J-20C fighter jet. 】
[Reward now: 2300 points. 】
[Your current points are: 7955 points. 】
[Next task: 7G construction. 】
[Task point reward: 4000 points. 】
Jiang Chen:? ? ?
7G?
Now that 5G has not been popularized in the Dragon Kingdom, is it going to be 7G?
Let me go, the system is really good at arranging difficult problems!
Is there really 7G in Wandering Planet?
Jiang Chen's mind went blank for a moment, and then his whole body felt bad.
He seems to have remembered it!
In the play, when Wu Gan received the emergency notification of the astronauts’ arrival, the phone displayed seemed to be 7G!
He was really convinced.
Can’t the astronaut emergency entry notification be sent using 5G? !
However, after calming down, Jiang Chen also understood the system's intention of arranging this task through the system's prompts.
Only 7G communication that realizes integrated communication between heaven and earth can support highly developed artificial intelligence. Just like before, MOSS remotely operated the artificial intelligence of a big player. When it comes to an emergency——
Network card.
If it were under 7G, it would be impossible for such a thrilling thing to happen.
In addition, Kunpeng drones are now about to enter service. If you want to control thousands of Kunpeng drones at the same time, it is really impossible to operate without 7G.
According to the system description, the peak data transmission speed of 6G reaches 100Gbps-1Tbps, which is 10-100 times that of 5G.
7G can reach 10,000 times that of 5G!
Not to mention ordinary data, even the consciousness in a human brain can be uploaded to a computer in a second with the help of 7G!
Jiang Chen realized that 7G communication must be done.
If there is no way to solve the 7G problem, it will be difficult for the world to develop.
When Jiang Chen's technology is really put to use, there will be no basic communication network support.
Communications are not developed, and other technologies cannot bring them forward.
Relying solely on mobile 5G to develop high technology is empty talk!
Jiang Chen sighed slightly, resigned to his fate and asked MOSS to find information about communications engineering.
While looking for information at MOSS, Jiang Chen looked through the system's mall, hoping to find technology related to civil aviation aircraft. After searching all over, he only found an X engine.
X engine?
What engine is this? Jiang Chen clicked on the parameters to check, and the more he looked at them, the more frightened he became.
It is actually 100 times better than the LEAP-1C engine sold to Longguo by CFM International in the previous life!
Not to mention the thrust-to-weight ratio directly reaches 20, and with scramjet technology, the speed can reach Mach 16, and the fuel efficiency is increased by 70%!
Taking a common A320 or B737 as an example, their current fuel consumption is about 2.5 tons to 3 tons per hour, but if the engine is replaced by an X engine, the fuel consumption will only be about 0.75 tons to 0.9 tons!
Great value for money!
Jiang Chen felt happy and looked at the price tag of the system.
