Chapter 600: We can too

"Wait!" Mr. Gu said.
How did Qin Guan know the shortcomings of this aircraft? How could he blurt out its shortcomings? Mr. Gu didn't know. But now, if Qin Guan goes on to say that this aircraft is not a bullshit, then he might really let him. This model was discontinued.
After all, it only has this drawing in front of it, and it relies on this drawing to convince the Air Force.
Qin Guan is not selfish, but open. Qin Guan strongly supports Super Seven and the Raptors fighter project. However, if this J-8-2, Cai Guoqing in the air, wants to develop, Qin Guan also hopes to succeed. of.
In this case, all kinds of problems need to be corrected.
For example, although the J-8 produced two engines, due to the out-of-control design of the center of gravity, it elongated the front fuselage by more than one meter, making the center of gravity significantly ahead of the aerodynamic center of the wings, ensuring the flight stability and controllability of the aircraft. Sex. The substantial extension of the distance from the air intake to the front end of the engine has severely damaged the total pressure recovery of the F-8.
Since the engine cannot get enough intake pressure during operation, the thrust loss is very large, and the true thrust level after installation is much lower than the result of the bench test. What’s even more funny is that the ejector tail cover used by the J-8 is not only very heavy, but actually can’t play the role of the ejector tail cover and will only lose thrust in vain.
If these improvements are made, the performance of the J-8 can be greatly improved. Now Qin Guan hopes to speak out all kinds of problems.
However, Mr. Gu stopped him from speaking.
"Mr Qin, since you can see that there is a problem at a glance, then tell me, how can this be changed?" Mr. Gu's face was smiling, but his heart was extremely dissatisfied.
You just talk about it! You look like an airplane expert. All of us here are not as good as you. Without you, you have the ability, so you can talk about how to change it!
Hearing Mr. Gu's words, Qin Guan sighed in his heart. Now that he is like this, it is definitely not a fault. He hopes that the J-8-2 will truly mature.
However, the other party has obviously misunderstood him, and, in his own way, it seems that he really dismantled the stage.
How to change? Of course I know.
In later generations, they also insisted that there was no problem with their design, and they had been fighting with the Air Force. It was not our design problem, but your operation problem!
In the end, the Air Force could not stand it. Around 2000, it dismantled the aircraft for ground simulation tests. In the second half of 2001, it gave a very genius approach to replace part of the hard hydraulic pipelines with hoses in the connecting pipes of the hydraulic system. Pilot-controlled manual valves are installed on the road. This device was promoted throughout the army in 2002.
That's right, let the pilot control it manually. Once a set is damaged, the tee will be blocked. Even if that is the case, the 6601 Institute adheres to its own design philosophy. I am superfluous and absolutely no problem!
It was difficult for Qin Guan to change immediately with his own efforts.
Now, how do I change my request? Is it also a manual control?
"If you want to improve it and at the same time improve the J-8's air combat performance, then you can only use more than four degrees of digital telex." Qin Guan said.
Hearing Qin Guan's words, the bricks who were present suddenly gasped.
You said it happily, a few words, more than four degrees of digital telex, do you know how complicated it is? Do you know that even in the West, digital telex with more than four degrees is just beginning?
Moreover, the four-degree digital telex in the West is all caused by crashes. Whoever has not fallen a few times is embarrassed to say that it is such a dangerous nature that it should be developed by itself?
"How is that possible? Does our second-generation machine still need telex control?" The engineer who was still dissatisfied with Qin Guan just now spoke immediately.
"You are right. No matter how strong this aircraft is for interception, it is also a second-generation aircraft. Our Air Force now needs a second-generation aircraft?"
Qin Guan asked, the other party blushed immediately. That's right, he was completely wrong. He slapped himself in the face. They developed a high-performance third-generation machine. How could it be called a second-generation machine?
The whole world is working hard to get closer to the third-generation machine. What second-generation machine is it still working on?
"This J-8 fighter is improved from the J-7, and it is indeed the foundation of the second-generation fighter." Qin Guan continued to say to everyone: "However, we must not treat it purely as a second-generation fighter. It must not only have long-range interception capabilities, but also have air combat capabilities. Since the 6601 Institute has decided to replace it with a domestically made large-caliber radar, why dare not to replace it with a more than four-degree digital telex? , The technical experts of the 6601 Institute are not as good as the 6611 Institute?"
When Qin Guan said this, they were completely speechless, yes, how could they give up?
At present, the Raptor fighter model copied by 6611 is progressing rapidly. The full-moving canard fighter can only be controlled by digital telex. Everyone has overcome the difficulties of digital telex. Various supporting parts are also available. After the design is completed in China, it can be said that they only need to take those parts and install them on the J-8, and they can write the program for the J-8.
In this way, these backward hydraulic control systems are not needed.
In this case, it seems that the technical difficulty is not great.
It doesn’t seem to be too difficult to install the F-E-8 with telex control. In later generations, there will be such an aircraft, the F-Eight 2ACT. The following letter is the abbreviation of active control technology, which means active control technology. It can be regarded as the first digital three-axis and four-degree fly-by-wire flight control system with no mechanical backup, full-time and full-efficiency, developed by Han Guo.
This aircraft has functions such as control stabilization, neutral speed stability, flight boundary control, autopilot, emergency electric backup, relaxation of static stability and direct force control.
It can be said that the digital telex of the Han country was done on the Jianba. If you do it now, what's the big deal? In short, your own opinions have been put forward. , Moreover, the current control flaws of the J-8 are plain and clear.
Are you even worse than 611? This second-generation aircraft is already behind. The Raptors are considered third-generation aircraft. If you don’t want to change anything, just graft the MiG 21's nose and install the radar fire control. To fool people, there is no such thing as fools.
General Zhang has already photographed the table because of the fooling of foreign fighters. If you continue to fool, you will definitely be photographed.
It is to provoke the competition between them. Only with competition can there be development and progress. This has always been Qin Guan's philosophy. In order to make the motherland's military industry truly powerful, Qin Guan is willing to be a villain.
"What is 6611, what they can do, we can definitely do it too." Mr. Gu said, "We will go to the digital telex."
