Chapter 611: Two problems

"President Qin, I toast you a cup." At this moment, a voice came from behind him.
Qin Guan turned his head and watched Lu Lao walk over with a wine glass.
Mr. Lu is already nearly sixty years old. He doesn't like flattery or flattery all his life, and he doesn't like to go to the top of the camp by drilling, but today, he took the initiative to take the wine glass.
He wants to thank Qin Guan.
Without Qin Guan’s help today, their 6,650 institutes would definitely have to continue to study the Strong Six and Strong Six projects. It must be the last project of Mr. Lu. It was his life's hard work. However, the prospect of this project, Lu Being old is not guaranteed.
He didn't know how far this project could go. After all, the country's funding was limited, especially today, when he heard that the introduction of Tomcats began to discuss, he became even more nervous.
If the Air Force introduces the Tomcat, the funding will definitely be extremely tight. Many projects have to be cut off. For example, the 6650 Research Institute has no background in the Ministry of Aviation Industry, and any backstage research institute is the easiest to cut off. .
However, after a turn of events, they were able to undertake the surveying and mapping task of the Tomcat fighter. At that time, of course he would not retreat. Even if he had to spare his life, he would have to succeed in surveying and mapping.
He never complimented anyone. An old man like him came to respect a young man out of gratitude. On behalf of the entire institute, he was grateful to Qin Guan.
"Old Lu, I dare not be it." Qin Guan raised his glass: "I still respect you. You are also the veteran of domestically developed aircraft. I believe you will successfully survey and imitate our advanced fighter aircraft, and will develop into A series."
Before Qin Guan finished speaking, Lu Lao's wine was poured into his mouth, and his friendship was shallow, licked, deep, and boring. Now Lu Lao's friendship with Qin Guan is in this wine.
"Lao Lu, slow down." Qin watched a glass of wine and his stomach turned red, and Qin Guan knew that Lao Lu could not drink much.
"Come on, Lao Lu, sit here." The commander of the Air Force on the side stepped aside and added a chair.
Old Lu sat down, looked at Qin Guan, and said, "Mr. Qin, we have to imitate the Tomcat fighter. There are still some problems."
Mr. Lu has already begun planning to imitate the Tomcat, and the imitation of this aircraft is not easy.
Qin nodded his opinion: "Yes, there are two difficulties. First, the welding of the titanium alloy wing box."
The Tomcat fighter has a variable swept wing. The axis of this wing is the most important. It must have sufficient strength and it must be light.
Therefore, it is necessary to use titanium alloys. Among them, the welding of titanium alloys is the biggest difficulty. If this technology cannot be broken, the variable swept wing cannot be talked about.
Lao Lu is studying variable swept wings recently. Of course he knows that this is a difficulty. If this difficulty cannot be overcome, there is no way to talk about imitation.
This is the first.
"The second is the engine." Qin Guan said.
Any fighter must have an engine. Different fighters have different engines. For example, the engines used on Super-7s cannot do anything domestically.
But the Tomcat is different.
The Tomcat fighter is invincible as a whole. It is dragged down by the TF30 engine. Historically, the Tomcat has become an invincible cat until the mature F110 is developed.
This time I went to Eagle Country and visited Tomcat, but the engine was defective, and the others were all levers.
However, Qin Guan still has a solution for this engine.
Historically, the Eagle Nation's navy did nothing, and even considered Spey when planning an emergency.
Yes, it is Spey. Although the performance of Spey is not good, it is mature and reliable after all. Now, Han Guo has started to localize Spey, and it has also started to increase its push. It is proper to install Spey. That's it.
Old Lu opened his eyes wide and looked at Qin Guan: "Ms. Qin, you are really amazing."
Qin Guan is a layman, but he speaks better than an expert. What he said is what Lu thinks in his heart. As long as these two difficulties are solved, the imitation Tomcat will be no problem within one year!
President Qin has already raised the question, so how should we solve it?
"There are also solutions." Qin Guan said: "For the engine, use our Spey or a modified Spey. There is absolutely no problem in power. As for the welding of this titanium alloy, it is indeed a big problem. , You can ask comrades from the relevant parties to solve it. If they can’t solve it, then come to me again.

Even Grumman developed the Tomcat at that time. The key to success or failure was the welding of the titanium alloy wing box. At that time, an engineer invented vacuum beam welding, which was a perfect solution. When the Tomcat was retired, the wing box did not show any cracks. .
By 2020, that set of welding equipment will definitely be eliminated. If it enters the machine tool cemetery, I can go there and double it myself.
It’s been a long time since I used the system in my brain. When I needed it, I had to use it, all for the motherland.
Qin Guan talked about his thoughts, and the atmosphere here was very harmonious.
On some desks, that's not necessarily the case.
Mr. Gu took a few bites of food indiscriminately, and his mind was confused.
What should I do if there is a problem with the J-8-2 project that was good at first?
"If you continue to survey and imitate the blue shark, the ministry will support it." A voice came from my ear.
If you can’t rely on the J-8-2, then continue to develop new fighters, imitate the Blue Shark, and compete with them.
Listening to his ears, Mr. Gu can only agree that imitation is not easy. There is a large proportion of titanium alloys. We don't even master the welding technology of titanium alloys. How can we copy them?
Well, but it's still not certain now, will Qin Guan go to the Kingdom of Peace, will everything go well? Maybe I can't buy the Tomcat.
It is better to complete the avionics upgrade of the J-8-2 first, so that it has the ability to intercept at a medium range.
Mr. Gu continued to pick up the meal, feeling confused.
The night is already very dark.
The meeting can't be finished in one day, and there will be several days of meeting. After Qin Guan finished his meal, he rode the Warriors off-road vehicle and went back with Xiang Jingxiu.
"Hey, why do you have this expression?" Although Qin Guan drank a few glasses of wine, he was still very sober. The two of them had strange expressions.
"Mr. Qin, do you know how important your security work is? We are in the country and we are tired of taking care of your safety every day. Now, you are going abroad again!"
Xiang Jing spoke.
Are you worried about my safety? How do you look like you are excited? You have been holding back for a long time, and finally have a chance, right?
It's the eagle, who wants to spread its wings and fly high. It is indeed difficult for the fighters who came out of the vulture army to serve as bodyguards for themselves.
