After Jiang Yan finished saying this, he suddenly remembered, it seems that there is no way to get a civil aircraft, and it is okay to introduce it if the research fails.

At the beginning of the founding of the People's Republic of China, under the embargo of Western countries, civil aviation mainly introduced woolly bear aircraft. At the end of the 50s of the 20th century, relations between the two countries reversed. The leader of the Mao Bear country once threatened that without the help of the Mao Xiong, China would be "isolated from the world" in air traffic. At this time, the urgency of civil aviation to "fly out" (fly to the world) and get rid of coercion is even more urgent.

In 1961, John Cow Vickers came to China to sell the "Viscount" aircraft. On March 14, 1961, according to the instructions of the higher authorities, our experts compared the technical performance of the "Viscount" aircraft with that of the Il-18 aircraft.

Because the life of the "Viscount" aircraft and its engines is longer than that of several existing transport aircraft in China, the aircraft and engines can be used for more than 3 years without having to go abroad for repair, and other aspects are also very suitable for domestic routes.

On November 15, 1961, experts recommended the purchase of 6~10 "Viscount" aircraft. The superior gave instructions to purchase 6 aircraft. On December 1, the Machinery Import and Export Company of the Ministry of Foreign Trade came forward to sign a contract with John Bull Vickers Aviation Co., Ltd. for the purchase of six "Viscount" 843 aircraft. China sent personnel to John Bull to study, and John Bull delivered in Guangzhou.

The contract has already been signed, although it is said that our country is still under the siege of the Western embargo, but it seems that this "Viscount" aircraft is not in this range.

Because the "Viscount" is a passenger aircraft with four turboprop engines designed by the original Vickers Company in the United Kingdom, the first flight was in April 1945, and the production was discontinued in March 1964, and the total production of various types of "Viscount" passenger aircraft reached 444.

Compared with conventional piston aircraft, the "Viscount" aircraft has two major advantages: first, it is faster, up to 576 km/h; Second, it can fly higher, so that the cruising altitude is in the stratosphere, so that passengers can ride more comfortably. These two advantages made the "Viscount" very popular after it was put into service, and it was improved many times, from the original model to the 700, then to the 701, 800 and 810 types, and a variety of engines were used. The passenger capacity increased from 43 to 75 people, the range increased to 2775 kilometers, and the engine power increased to 1990 horsepower. And the economy has been greatly improved, fuel consumption has been reduced by more than half compared with the passenger aircraft of the time. Therefore, it has been highly valued by the air transport community.

Compared with this aircraft, Jiang Yan attaches more importance to its engine, the "Dart" turboprop engine is a good engine, which has been exported to many countries and is a quite good engine.

Because of our relationship with the woolly bear, the West has become a state of wooing us, and the relationship with John Bull is still relatively close during this period, why not introduce his production line and aircraft engine production line, so that you can study your own aircraft, according to Jiang Yan's knowledge, this aircraft is a backward aircraft in the West, and it should not be too difficult to introduce.

And John Bull is the first adult in our country after the establishment of the country's Western countries, this old gentleman, has always been above the top, for our country has an indescribable feeling, our country and the West during the honeymoon period, from them there are no less good things, and even many are still half sold and half sent,

The most important point is that due to the emergence of Jiang Yan, there are a lot of agricultural and sideline products and some primary industrial products, and the country has also changed its thinking about appearance, and with the participation of the state, it has increased the ability of agricultural and sideline products in research and development.

The country's foreign exchange is not much now, but it is much better than it was in history.

In fact, what Jiang Yan didn't know was that the precision detector imitated by Jiang Yan also exchanged a lot of foreign exchange for the country.

"Let's talk about it when we have time." Jiang Yan thought of this and changed his words.

"Okay, no problem, let's solve the problem here first, and then go back to Sijiu City and talk about it in detail." Dean Tang saw that there was a way, and opened his mouth with a smile.

After greeting Jiang Yan, Dean Tang said to the middle-aged man beside him, "Lao Shen, this is Comrade Jiang Yan." ”

Then he introduced to Jiang Yan: "Comrade Jiang Yan, this is the director of Shen Chongshen of Nanfei. ”

After listening to Dean Tang's introduction, Director Shen stretched out his hand very enthusiastically and shook it with Jiang Yan's outstretched hand.

"Hello Director Shen." Jiang Yan took the lead in greeting

Director Shen said enthusiastically: "Mr. Jiang, hello, welcome to Nanfei, for your name, I am like thunder, it is really better to hear than to see, I didn't expect Mr. Jiang to be a young talent." ”

"Our latest fifth master can successfully test fly and take off, but thanks to your help, if it weren't for you, our fifth master would probably have to wait a few years to be born!"

After the greetings, Director Shen said to Jiang Yan: "Mr. Jiang, you have been on a hard journey all the way, why don't we go and rest first?" And then at work, after all, the body is not the capital of the revolution. ”

Jiang Yan, who heard this, glanced at the people present and said, "Director Shen, thank you for your kindness, I'm not tired yet, I don't need to rest, I want to go and see the plane first, can I?" ”

In fact, as soon as Director Shen saw Jiang Yan just now, he wanted to tell him about the second fifth master, but considering that Jiang Yan came from Sijiu City on a tiring journey, he was embarrassed to let the family rest without resting, so he worked immediately, and the donkeys in this commune did not dare to use it like this.

But now that Jiang Yan has taken the initiative to mention it, of course Director Shen can't wait, after all, the second plane had such an accident, and Shen Chong, as the factory director, is still under great pressure, and he has not rested for several days for a while.

So he took Jiang Yan and his party to the hangar where the second prototype of the fifth master was placed.

After arriving at the hangar, Director Shen said to Jiang Yan: "Mr. Jiang, about the basic situation of this fifth master, I think on the way here, our chief engineer Lu has already told you, this second fifth master, we have basically realized the national production of parts and components." ”

"But in the process of test flight, we found the resonance phenomenon, and we also organized a lot of people to check it, but we just couldn't find the problem......

"Mr. Jiang, you are also one of the chief designers of this aircraft, so I invited you over, you have to help us diagnose it."

Director Shen said this very loudly, not only for Jiang Yan, but also for those behind him.

Just after Jiang Yan got out of the car, and on the way to the hangar, the people behind him were talking.

Director Shen is among the people present, except for Dean Tang, the oldest and highest-ranking person, he has understood Jiang Yan's relevant abilities, especially Jiang Yan's contributions to the Five Masters project.

But those people in the back, out of secrecy and their own level restrictions, they don't know much about Jiang Yan.

Many of the people present were temporarily transferred from various research institutes across the country, and they were also elites in this industry, and most of them were above the top. Especially when they saw Jiang Yan so young and came alone, they were even more skeptical about Jiang Yan's ability.

Generally speaking, everyone is a scientific research group, or a project team of many people comes together, but Jiang Yan came alone. If Jiang Yan were alone, he would have found out the problem, wouldn't it seem that they were too useless.

Of course, they still have basic respect for Jiang Yan, after all, Jiang Yan's special design room has come up with a new type of improvement plan for the fifth master, and has imitated so much equipment, which they can't do before.

However, these people always thought that Jiang Yan's special studio was composed of a large number of professional aviation experts, otherwise they would not have come out with so much equipment, and when Jiang Yan arrived, they knew that strictly speaking, the researchers in this special studio in Sijiu City were only Jiang Yan himself, and the others were to assist him, so these people had strange ideas.

All kinds of discussions also came and went, but of course Jiang Yan heard these discussions, but he didn't take them to heart at all.

After all, no matter what time it is, there are always those who can't see the good of others and dump the pot everywhere.

Especially those turtles who think they have drunk foreign ink outside for a few years, they look down on this and that, as if foreign is fragrant.

For such a person, Jiang Yan is too lazy to take care of it!
