Doomsday Bunker Upgrade

Text 384 Chapter Straight 20 Helicopter

Because of curiosity, Chen Xin left the office and walked to the outside corridor. Because of the cold protection, there is a glass corridor outside this row of barracks, which can see the outside and effectively block the cold, so that Chen Xin can see without going out. what's happening.

In the center of the barracks, on a specially leveled snowfield, a huge black helicopter was slowly landing.

This is a large helicopter with a round head and a round brain, but without losing the edges and corners. Five huge rotors are gradually stopping, and the heavy weight and even the undercarriage of its own are sinking into the snow on the ground.

Fortunately, the snow was leveled beforehand, and the helicopter just sank a little and stopped steadily.

Looking at this helicopter, Chen Xin couldn't help but raise his eyebrows. Although he is not a fan of the military, he was able to recognize the Z-20 helicopter, which was only equipped with the Yan Nation army before the disaster, and has a high degree of online spread. After all, it is conspicuous The five rotors are still very characteristic.

As a domestically produced helicopter very similar to the famous Federal Black Hawk helicopter, it was just installed with the Yan Nation army at the beginning of the disaster, which is regarded as the cutting-edge equipment of the army.

It’s just a pity that before the army had a good time playing with its new toys, a meteorite fell, making the air full of dust, making it difficult for all aircraft to take off.

It is important to know that aircraft engines because of their huge demand for air intake, but there is no such thing as air filters. If a large amount of dust or particles in the air enters the aircraft engine, it is easy to damage the aircraft engine and cause the entire aircraft to be scrapped. .

Coupled with the strong winds caused by the collapse of the weather system after the disaster, and the loss of the danger of satellite navigation in the dark environment after the sky is covered by dust, not only large aircraft, but even small aircraft such as helicopters, all aircraft Never took off again.

But now the arrival of this straight 20 clearly indicates that Yan Guo seems to be back in his airspace again.

This obviously makes Chen Xin a little curious, how does this Z-20 solve the problem of dust and particles in the air, or can the current air quality allow the plane to take off?

With such doubts, Chen Xin also noticed that something seemed to be installed on the air intake of this straight 20, but the light was dim and Chen Xin could not see clearly.

Just when Chen Xin was puzzled, the political commissar of the special forces came in from outside.

"What's the matter with this helicopter? Is the plane ready to fly now?" Chen Xin looked at the political commissar and asked him curiously.

"The aircraft has not gone around yet. The helicopter in front of us is used for testing, mainly to test the new air filter installed on the aircraft to see if the helicopter can fly normally with the air filter installed." Obviously he understood the situation, and he came to Chen Xin for this purpose: "In addition, there are things on this plane that were sent to you, Comrade Chen Xin. In addition, I also hope that Comrade Chen Xin can be The air filter of the aircraft should be checked to see if there is any room for improvement."

"Give me something? What is it?" Chen Xin was surprised when he heard that the plane in front of him was coming to deliver something to himself.

Even though I know that I can enjoy generous treatment nowadays, using a helicopter to deliver supplies to myself is no ordinary treatment!

Compared with the personal protection of a whole special force, a helicopter clearly made Chen Xin more intuitively feel the treatment he enjoys now.

As for the aircraft air filter mentioned by the political commissar, Chen Xin remembered that in the previous improvement project that he cooperated with the country, it seemed that there had been an air filter improvement. At that time, Chen Xin thought it was for cars. I used the new air filter, and once wondered why an automobile air filter needs such a large amount of air intake.

Now it seems that I should have misunderstood its purpose. The air filter with large intake air volume is obviously for the aircraft.

Chen Xin remembers that he upgraded the filtering effect and ventilation of the air filter according to the requirements, and also improved the material of the air filter element to make it more durable. Not to mention, it can be cleaned directly by washing. It can be said that the performance of that air filter is greatly improved.

Judging from the smooth landing of the helicopter, it seems that he has invisibly contributed to the return of the aircraft to the sky.

Thinking of this, Chen Xin couldn't help feeling a wave of excitement and excitement. You must know that with a plane, many things will be very different.

Take the snow disaster in the city as an example. If two helicopters like the Z-20 could be obtained in the urban area, the rescue team would not need to drive over at great risk.

You must know that the take-off weight of a Z-20 is more than ten tons, and it can carry at least two tons of materials or transport a squad of soldiers. With the number of rescue teams and the materials carried at the time, the UU can fly. In just a few trips, the entire rescue team and supplies can be transported from the urban area to the immediate city, and medical personnel and relief materials can be continuously transported from the urban area to the immediate city.

Compared with the current situation, it takes a lot of trouble to transport people and materials from the urban area to the immediate city, but it is much more convenient.

And more importantly, if the helicopter can take off normally, the connections between different places will become closer again, and both material transportation and information transmission will become more efficient and faster.

Coupled with the new type of communication network that the country is preparing to build, it is enough to restore the country's ability to control the locality to the level before the disaster, so that the entire country will return to a whole and exert a stronger force.

"Let's go, go and see!" Chen Xin couldn't restrain his mood at this time, returned to the room and put on his own protective clothing, and left the barracks with the political commissar, and walked on the snow to the apron.

At this time, the engine of the Z-20 helicopter had completely stopped, and a white gas could be seen on the engine shell, and a layer of frost was quickly formed on it.

But this does not affect the mighty and handsome look of this straight 20 helicopter, but adds a different kind of momentum to it.

"You are Comrade Chen Xin? Hello, here is a piece of material for you. Please sign for it." Next to the plane, a man in the uniform of an Air Force pilot took out a document and handed it to Chen Xin. He signed.

Chen Xin had heard the political commissar mention this matter just now, and naturally he was not surprised.

Reaching out and accepting the document, Chen Xin opened his eyebrows and said, "These things are too..."
