Doomsday Bunker Upgrade

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 not only see the outside, but also effectively block the cold, so that Chen Xin can see without going out. what happened.

In the center of the barracks, a huge black helicopter was slowly descending on a piece of snow that had been flattened out.

This is a large helicopter with a round head and a round head, but it does not lose its edges and corners. The five huge rotors are gradually stopping their rotation.

Fortunately, the snow had been leveled beforehand, and the helicopter just sank a little and then stopped steadily.

Looking at this helicopter, Chen Xin couldn't help but raise his eyebrows. Although he is not a military fan, this helicopter was equipped with the Yan Guo army before the disaster. Chen Xin can still recognize the Z-20 helicopter with a very high degree of spread on the Internet. After all, it is conspicuous. The five-rotor is still very characteristic.

As a domestic helicopter very similar to the Federation's famous Black Hawk helicopter, it was just installed in the Yan Kingdom's army when the disaster struck, and it was regarded as a cutting-edge equipment for the army.

It's just a pity that before the army could play with its new toys, a meteorite fell, filling the air with dust, making it difficult for all planes to take off.

You must know that the aircraft engine has a huge demand for air intake, but there is no such thing as an air filter. If a large amount of dust or particles in the air enter the aircraft engine, it is easy to damage the aircraft engine and cause the entire aircraft to be scrapped. .

Coupled with the high winds caused by the collapse of the weather system after the disaster, and the danger of losing satellite navigation flight in the dark environment after the dust clouded the sky, not only large aircraft, but even small aircraft such as helicopters, all aircraft It never took off again.

But now the arrival of the Zhi 20 in front of him clearly indicated that Yan Guo seemed to be back in his airspace again.

This obviously made Chen Xin a little curious, how did this Zhi-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 at all.

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

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

"The aircraft has not yet returned to flight. This helicopter 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." Political commissar Obviously he understood the situation, and he came to Chen Xin for this very reason: "In addition, there are things on this plane for you, Comrade Chen Xin, and I hope that Comrade Chen Xin, you can tell me. Check the air filter of the aircraft to see if there is anything that can be improved."

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

Although I know that I can enjoy favorable treatment now, using a helicopter to deliver supplies to myself is not an ordinary treatment!

Compared with the personal protection of a whole special force, a helicopter obviously made Chen Xin feel the treatment he was enjoying more intuitively.

As for the aircraft air filter mentioned by the political commissar, Chen Xin remembered it. In the improvement project he cooperated with the state before, it seems that there was an improvement of the air filter. At that time, Chen Xin thought that it was for the car. I used a new type of air filter, and I once wondered why a car air filter needs to have such a large air intake.

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

Chen Xin remembered that he upgraded the filtration effect and ventilation volume of the air filter according to the requirements, and also improved the material of the air filter element to make it more durable. It can be said that the performance of that air filter has been greatly improved.

Judging from the smooth landing of the helicopter in front of him, it seems that he has virtually contributed to the return of the plane to the sky.

Thinking of this, Chen Xin couldn't help but feel a surge of excitement and excitement in his heart, knowing that with the plane, many things will be very different.

Taking the snow disaster in Linshi as an example, if two helicopters like the Z-20 could have been obtained in the urban area, the rescue team would not have to take great risks to drive here.

You must know that the take-off weight of a Z-20 exceeds ten tons, and it can carry at least two tons of materials or transport a class of soldiers. With the number of rescue teams and the materials carried at that time, the plane can fly the entire rescue after a few flights. The team and materials were all transported from the urban area to the neighboring city, and it was also able to continuously deliver medical staff and relief materials from the urban area to the neighboring city.

Compared with the current need for a lot of twists and turns to be able to transport personnel and materials from the urban area to the adjacent city, it is much more convenient.

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

Coupled with the new communication network that the country is preparing to build, it is enough to restore the country's ability to control local areas to the level before the disaster, allowing the entire country to reunite and play a stronger role.

"Let's go and have a look!" Chen Xin couldn't hold back his mood at this time. He went back to his room and put on his protective clothing.

At this time, the engine of the Z-20 helicopter has completely stopped, and a layer of frost can be seen on the casing of the engine at the same time.

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

"Are you Comrade Chen Xin? Hello, there is a supply here for you, please sign for it." Beside the plane, a man wearing an Air Force pilot uniform took out a document and handed it to Chen Xin, indicating He signs.

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

Reaching out to take the document, and opening it, Chen Xin's eyebrows couldn't help but fly: "These things are too..."
