Chapter 385

Because of curiosity, Chen Xin left the office and went to the corridor outside. Because of the cold protection, there is a glass corridor outside the barracks, which can not only see the outside, but also effectively block the cold, so that Chen Xin can see what happened without going out.

In the middle of the barracks, a huge black helicopter is slowly landing on the specially leveled snow.

This is a large helicopter with round head and round brain, but without losing its edges and corners. The five huge rotors are gradually stopping rotating, and their huge weight and even the landing gear are trapped in the snow on the ground.

Fortunately, the snow had been leveled in advance, and the helicopter just sank down a little and stopped steadily.

Looking at this helicopter, Chen Xin can't help but raise eyebrows. Although he is not a military fan, Chen Xin can recognize this zhi20 helicopter, which was only equipped with the army of Yanguo before the disaster and has a very high degree of spread on the Internet. After all, its prominent five rotor is still very characteristic.

As a domestic helicopter very similar to the famous Black Hawk helicopter of the Federation, it was just installed in the army of the Republic of China at the beginning of the disaster. It is regarded as the new equipment of the army.

It's just a pity that before the army can play with its new toys, the meteorite has fallen into the sky, making the air full of dust, making it difficult for all planes to take off.

We should know that the aircraft engine has a huge demand for air intake, but there is no such thing as air filter. If a large number of dust or particles in the air enter the aircraft engine, it is very easy to damage the aircraft engine and cause the whole aircraft to be scrapped.

Coupled with the strong wind caused by the collapse of the weather system after the disaster and the loss of the risk of satellite navigation flight in the dark environment after the dust obscured the sky, not only large aircraft, but also small aircraft such as helicopters have never taken off again.

But now the arrival of the zhi20 clearly indicates that Yanguo seems to have returned to its own airspace.

This obviously makes Chen Xin a little curious. How does the zhi-20 solve the problem of dust and particles in the air? Or is the air quality ready to allow the plane to take off?

With such doubts, Chen Xin also noticed that something seemed to be added to the air inlet of the zhi20, but the light was dim and Chen Xin could not see clearly.

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

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

"At present, the plane has not gone around. This helicopter is used for testing, mainly to test the new air filter installed on the plane, to see if the helicopter can fly normally with the air filter installed." The political commissar obviously understands the situation, and he came to Chen Xin just for this matter: "in addition, there are things sent for Comrade Chen Xin on this plane. In addition, I hope Comrade Chen Xin can check the air filter of the plane to see if there is anything that can be improved."

"What did you bring me? What is it? " Chen Xin was surprised to hear that the plane in front of him came to deliver things to him.

Although I know that I can enjoy good treatment now, it's not a general treatment to use a helicopter to deliver materials to me!

Compared with the close protection of the whole special forces, a helicopter obviously makes Chen Xin feel the treatment he enjoys now more intuitively.

As for the aircraft air filter mentioned by the political commissar, Chen Xin remembered that in the previous improvement project he cooperated with the state, it seemed that there was an improvement of the air filter. At that time, Chen Xin thought that it was a new type of air filter for cars, and he once wondered why a car air filter had to do so much air intake.

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

Chen Xin remembers that he upgraded the filtering effect and ventilation capacity of the air filter according to the requirements, and also improved the material of the air filter element to make it more durable. Needless to say, he could clean it directly by washing, which greatly improved the performance of the air filter.

Judging from the fact that the helicopter can land smoothly, it seems that it has helped the plane return to the sky.

Thinking of this, Chen Xin can't help feeling excited and excited. You know, with a plane, many things will be very different.

Take the snow disaster near the city as an example. If we could get two helicopters like zhi20 in the urban area at the beginning, the rescue team would not have to drive over at great risk.

It is necessary to know that a straight 20 aircraft with a take-off weight of more than 10 tons can carry at least two tons of materials or one class of soldiers. According to the number and materials of the rescue team at that time, the aircraft only needs to fly several times to transport the whole rescue team and materials from the urban area to the nearby city, and it can continuously transport medical staff and rescue materials from the urban area to the nearby city .

It's much more convenient to transport people and materials from the urban area to the city than it is now.What's more, if the helicopter can take off normally, the connection between different places will become closer again, and both material transportation and information transmission will become more efficient and fast.

In addition, the new communication network that the state plans to build is enough to restore the state's control over local areas to the level before the disaster, so that the whole country can return to a whole and play a more powerful role.

"Go and have a look!" At this time, Chen Xin could not restrain his mood. He went back to his room and put on his protective clothing. He left the barracks with the political commissar and stepped on the snow to the apron.

At this time, the engine of the zhi20 helicopter has stopped completely, and a white gas can be seen on the shell of the engine. At the same time, a layer of frost is quickly formed.

But this does not affect the power and handsome appearance of the zhi20 helicopter, on the contrary, it adds a different momentum.

"Are you Comrade Chen Xin? Hello, here is a special 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 for his signature.

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

He took the document and opened it. Chen Xin's eyebrows flew up: "these things are too..."
