Siheyuan starts from a better life

Chapter 590, Transport Plane

More than two hours later, Jiang Yan's plane landed at a military base in the southeast.

Jiang Yan looked at the various fighter planes on the tarmac in the distance and felt quite emotional. In the 21st century, these fighter planes would be called antiques. Most of them were displayed in parks or Being dismantled... But in today's era, it is the main force in protecting our country's airspace. He took a curious look at it and didn't show much interest.

After getting off the plane, Jiang Yan saw Mr. Lu and his people waiting here early. After Jiang Yan greeted Mr. Lu, he got into Mr. Lu's car.

As soon as he got in the car, Jiang Yan asked Mr. Lu, "Chief Engineer Lu, what on earth happened to call me here in such a hurry?"

"Is there something wrong with my modification plans, or is there something wrong with the imitation equipment?"

Seeing Jiang Yan's anxious look, Mr. Lu said directly: "Xiao Jiang, it's not your problem, it should be other problems."

"Our prototype of the modification plan you provided has been tested and no problems have been found. We have also independently tested the equipment you copied, and there are also no problems. This shows that your plan is still good. The idea was quite successful.”

"The current situation is like this. We assembled the second prototype and when we were preparing for further adjustments and test flights, we found that resonance occurred shortly after the second prototype took off."

"Resonance?" Jiang Yan's eyes widened when he heard this.

Once an aircraft resonates in the air, it will cause devastating structural damage in a very short period of time. The pilot has almost no time to deal with it, so flutter is not allowed to occur within the aircraft's flight envelope.

"Has the resonance phenomenon been found on the first prototype?" Jiang Yan asked after regaining consciousness.

"No, the first plane was completely normal."

Speaking of this, Mr. Lu sighed and continued: "Although Fifth Master was produced by us independently, the first prototype before that, in addition to the equipment that you imitated, the parts of the entire aircraft were about More than one-third of them are shipped from Mao Xiong, and they are not 100% fully domestically produced.”

"When we were manufacturing the second prototype, we used all domestically produced substitutes. Every single component was rigorously tested before assembly, and no problems were found."

"But there were problems with these parts that were fine after they were assembled..."

In fact, resonance is nothing if it is placed on ordinary machinery and equipment. At most, the noise will be slightly louder. But if this matter is put on a fighter plane, it will not be a trivial matter. This may not be possible, but it may destroy people at any time!

Anyone who is engaged in aircraft design basically understands this.

Therefore, superiors attached great importance to this matter and mobilized relevant technical experts from all over the country to find out as soon as possible the cause of the resonance of the fighter planes.

These relevant technical experts, after more than half a month of research, have not found where the problem lies.

and so……

The only thing we can do is to call Jiang Yan, this magical person, over to take a look. Speaking of which, among these experts, Jiang Yan should be regarded as a "non-professional" who has not been officially certified.

After listening to General Engineer Lu's story, Jiang Yan basically had some idea in his mind. As long as there was no problem with the overall design parameters, he still had a certain degree of confidence that he could solve the problems that arose. Soon, the car carried Jiang Yan, Mr. Lu and his team to Nan Fei's location.

At this time, in order to keep it secret, Nanfei displayed the brand name of a certain capital machinery factory to the outside world, but the internal inspection was stricter.

There are already people standing in front of the office building. Everyone has heard that an expert from Sijiu City is coming today, so there are many related technical personnel waiting here.

Most of them are the elites in my country's aviation field in this era. Many of them have returned from studying abroad. They have never heard of any experts in the aviation field in the Forty-Nine City, and now they want to come and see them. experience.

Originally, they all thought that their technical level was one of the best in this era, but when they saw the transformation plan that Chief Engineer Lu got back, they changed their minds.

And when the equipment copied by Jiang Yan was shipped here one after another from Sijiu City, these technicians were even more shocked!

Especially those comrades with a relatively high level of confidentiality know a little bit about whether the transformation plan or the equipment came out of the special design room of a research institute in Forty-Nine City.

They couldn't help but sigh, our farmers are really crouching tigers, hidden dragons!

If they hadn't witnessed everything that happened, who would have imagined that this somewhat fantasy plot would actually happen in front of their eyes!

As soon as Jiang Yan's car entered the factory gate, he saw many people waiting for him in the yard through the car window.

When the car approached, Jiang Yan discovered that the leader was actually Dean Tang, and beside him stood a middle-aged man about fifty years old.

After seeing Jiang Yan get out of the car, Dean Tang stepped forward, shook Jiang Yan's hand and said, "Comrade Jiang Yan, are you still used to the road?"

Jiang Yan said with a smile, "Hello, Dean Tang, the journey was fine, but the transport plane we took was not produced by us. It flew a little slow and the ride was not that comfortable."

When Jiang Yan came to Nanfei this time, he took the IL-14 imported from Mao Xiong. The IL-14 is a piston twin-propeller design with a speed of 412 kilometers per hour and a maximum range of 1785 kilometers. It can carry passengers. 18-24 people.

The IL-14 aircraft focuses on improving the safety and comfort of the aircraft. It has relatively complete de-icing and anti-icing equipment, which effectively prevents ice accumulation on the wings, tail and propeller leading edges. The most distinctive design is that its cockpit windshield can be electrically heated, which will not produce frost and affect the pilot's vision. The instrument panel of the IL-14 aircraft is also equipped with a glide meter, which, in conjunction with the glide meter on the ground, can ensure a safe landing under complex weather conditions with clouds up to 30 meters high. In addition, its cabin is well-sealed, so even when flying in heavy rain, the cabin can still remain dry and comfortable.

It is precisely because of these advantages that our country has purchased 1955 IL-49s since 14 to undertake special planes and domestic passenger and cargo transportation tasks. However, after the relationship between the two countries became tense, our country no longer had a way to obtain this aircraft.

But for Jiang Yan, who is used to flying in medium and large passenger planes in later generations, he always feels that this plane is quite different! So when Jiang Yan heard Dean Tang ask, he blurted it out without even thinking about it.

After listening to Jiang Yan's words, Dean Tang's eyes lit up and he said with a smile: "Since Comrade Jiang Yan thinks that transport plane is not fast enough and comfortable enough, you might as well design one of our country's own that can fly fast and be comfortable." Comfortable transport coming.”

Regarding Dean Tang's words, Jiang Yan could only reply with a smile: "Haha, wait until I have the opportunity in the future."
