"Comrade Xiao Jiang has seen this plane before." Mr. Xu finally couldn't bear the question in his heart and spoke.

At this time, Jiang Yan said lightly: "When I was studying abroad before, I had a classmate's father who was an engineer who produced this aircraft MiG-19, and I saw and heard him talk about this aircraft, but then I also thought about it a lot. ”

In the country of hairy bears, the situation of this aircraft is quite embarrassing.

Soon after the radar-equipped MiG-17PF entered service with the Woolly Bear's Territorial Air Defense, the Woolly Bear found that the aircraft was not strong enough to stop John Bull's Canberra PRIII. and Eagle Sauce's RB-57D reconnaissance aircraft. In addition, Eagle Sauce's B-29 "Super Fortress" bomber was changed to night bombing, and the MiG-15 could not detect and intercept it, so Mao Xiong accelerated the development of an all-weather interceptor under development

So the Maoxiong government ordered the MiG Design Bureau to develop a fighter that could fly faster than the speed of sound and have a greater range than all the previous designs of the design bureau.

Prior to this, although the single-engine MiG-15LL and some experimental versions of the MiG-17 could fly at supersonic speeds for a short period of time, neither of them could maintain this speed on a sustained basis. The main goal of the program is to solve the maneuvering problems caused by how to continue supersonic level flight and supersonic flight, and the final result of the program is the MiG-19 fighter.

However, the MiG-19 fighter set a flight speed record of Mach 1.3 at that time. The production of MiG-19 fighters is not high, inferior to MiG-15 fighters and MiG-17 fighters, and with the emergence of the more advanced MiG-21 in the near future, it was quickly replaced by MiG-21 fighters, so it has become a tasteless thing to abandon in the country of hairy bears.

There is a way that the city is blooming in the city, and this aircraft has a huge development in our country.

Although this aircraft is relatively secret to the outside world, there is a certain degree of relaxation internally, otherwise Jiang Yan would not have seen his information and physical objects, otherwise he would have been arrested by the secret bureau of the Mao Xiong country.

But it's also their carelessness, they don't believe that anyone can remember so many materials at all, you must know that all the information of the entire aircraft is almost a room, and it took Jiang Yan more than two months just to read these materials.

However, when Jiang Yan looks at these materials, he will basically search his body, but who calls people to have space, which documents have a large part of the key information, Jiang Yan uses the equipment in the space to scan and preserve.

"You've seen the original drawings." As soon as Jiang Yan's words fell, his hand was grabbed by Mr. Xu, and his expression was quite excited.

So, Jiang Yan was confused by him, so he could only nod subconsciously.

"Great, great." Seeing Jiang Yan admitting it, Mr. Xu was a little happy and dancing. I was a little speechless with excitement.

"No, Mr. Xu, what's your situation." Jiang Yan felt a little unbelievable about Mr. Xu's appearance, so he asked with a confused look.

Mr. Xu also knew his gaffe, and after sitting down, he lit a cigarette and took a hard puff before speaking.

"The drawings of this aircraft we bought, the woolly bear people have set a lot of traps on it, and the tolerances of some parts are very different from the actual ones, and they can still produce when they are guided by the technicians of the woolly bear country, without their guidance, we basically can't produce them ourselves, and now all the researchers are comparing the drawings."

Hearing Mr. Xu say this, Jiang Yan suddenly realized, no wonder he remembered in his previous life that my country introduced this fighter in 58 years, and it could be mass-produced in 60 years, but the first batch of aircraft installed was in 64 years, and it turned out that there was such a thing in the middle.

However, this Mao Xiong Country did do a bit too much, according to Jiang Yan's knowledge, the type of aircraft we bought cost real money.

"Up to now, the revision of the entire drawing has been carried out tightly for less than one-tenth, and there are still a lot of things waiting for us to do, and time waits for no one!"

Mr. Xu sighed after saying this.

Although there has been great progress in the country's industry, compared with those developed countries, it is still not worth mentioning, and such a high-end thing as a jet aircraft cannot be completed without the strength of the whole country, and it has long been known that even in the later period, the number of countries in the world that can produce jet aircraft is only two palms.

However, this father has a mother, and it is better to have it yourself, which we are quite clear.

"How is the development of aircraft engines, and is there any flaw in those materials?"

The engine is the core of the aircraft, without him, you are no matter how good the design is, it is useless, the problem of the aircraft engine in later generations has plagued the country for a long, long time, and our scientists have solved such a problem after hard work.

Moreover, Jiang Yan also knew that when China purchased this type of aircraft, it also purchased a complete set of drawings for this engine.

And designated in Shengjing Liming Engine Plant to produce engines. According to the agreement, Mao Xiongguo successively sent the drawings of the MiG-58P to the Shenyang Aircraft Factory and the Dawn Engine Plant in the first half of 19 years.

In August 1958, the preliminary preparations for imitation were basically completed, and the imitation work officially began.

In the early stage, whether it was the imitation of the aircraft or the imitation of the engine, most of the parts were imported from the woolly bear country, especially the blades on the aircraft engine, and almost all of them were imported from them, and it was not changed until later generations.

In 1963, the Shengjing Dawn Engine Plant achieved the first flight of the turbojet-6. In fact, the Turbojet-6 was put into mass production in 1959, but for various reasons, this batch of engines had many flaws.

"Thanks to the A-1 metal you provided, the most rare blade problem for aircraft engines has been solved. There is also the importance we attach to the engine in the early stage, and there are almost no defects in the drawings of the engine, and I believe that a qualified engine will soon be imitated. ”

Hearing this, Jiang Yan breathed a sigh of relief in his heart, the most difficult thing to solve, the rest is a matter of time.

Thinking of this, Jiang Yan's face turned straight, and he stood up directly and said to Mr. Xu, who was sitting there: "Mr. Xu, please arrange the task!" ”

Seeing Jiang Yan's attitude, Mr. Xu nodded secretly in his heart.

"Sit down, sit down, don't be so serious."

After Jiang Yan sat down, Mr. Xu said: "Comrade Jiang Yan, I want to touch your low after talking to you today, so that you can arrange the follow-up work. ”

"So now I'm thinking about having you join our team to calibrate the drawings. I don't know what you mean. ”

"There is no problem, go and follow the organizational arrangement." Jiang Yan was very happy and agreed.

"I don't know where we work." Then Jiang Yan asked again.

"It's in the conference room on the third floor, and the drawing review team is basically here. I'll take you up in a moment. ”

Hearing this, Jiang Yan nodded, instructed the secretary to pack up his things, and then followed Mr. Xu to the third floor.
