Two J-11 fighters roared in.

They signaled the helicopter to make a forced landing, demanding that the helicopter land immediately.

Otherwise, they will resort to the necessary means of force.

Subsequently, the fighter moved into an attacking position.

"Let's land. ”

"Okay. ”

The helicopter slowly landed at a military airfield.

The guards quickly surrounded the plane.

The three of them obediently got off the plane.

found that there were actually two women, and the tension disappeared immediately.

Immediately, the three of them were taken to the airport office building. A sturdy colonel officer appeared.

"Captain!"

"Pei Lan?"

The colonel officer was surprised.

It's actually his original subordinate?

Pei Lan was also very surprised.

Isn't this her original deputy head of the regiment?

"What's the matter with you guys?"

"Report! We are testing the performance of the helicopter. As a result, the airspace was accidentally overtaken as a result. ”

"The helicopter flew to an altitude of 10,000 meters?"

"Yes. ”

The colonel's officer looked at them suspiciously.

It's not that Pei Lan is lying.

Rather, I wonder if the height is wrong?

Helicopters can also fly to an altitude of 11,000 meters, so what do you need fighters for?

"Who is he?" Wang Buan asked in a low voice.

"Du Yande. My former deputy head of regiment. Now it's the head of the regiment. Pei Lan replied solemnly.

While talking, someone sent the information to Du Yande.

It's all about the altitude, speed, flight trajectory and other information detected by the radar.

Repeated confirmation of the data shows that the helicopter did appear at an altitude of 10,000 meters, so that it accidentally occupied the airspace of the civil airliner.

Although there were no accidents. But it's also a dangerous thing. Every effort is needed to avoid it.

After all, in this airspace, no helicopter has ever appeared.

It is no wonder that the pilots of civil airliners reported as if they had discovered a new continent.

The superiors also thought that there was something strange, and quickly ordered the fighter to take off to intercept it. Unexpectedly, it was really a helicopter!

Du Yande didn't know much about helicopters. It can also be seen that it is not threatening.

It's completely a civilian helicopter.

"This is" Du Yande looked at Wang Buan.

"His name is Wang Bu'an. is a technician at the 220 Research Institute. Pei Lan said.

"220 Institute?"

"It is the research institute that developed the 125 aero engine. ”

"Oh. I know. ”

Du Yande nodded.

He certainly knew about the 125 engine.

Some of the J-11 fighters have been replaced with new engines. Combat effectiveness has skyrocketed. However, his flying group has not yet changed its outfit for the time being.

It is said that the production capacity of the 125 engine is insufficient, and it will take some time.

Wang Buan briefly explained the situation.

"Call Lu Hang next to me and ask the head of the regiment to come and take a look. Du Yande ordered to the person next to him.

"Army Aviation Regiment?" Wang Buan looked around curiously.

Is there also an army regiment next to it?

Around Qianzhou, there are so many troops?

As a common person who eats melons, I have never heard of it. Is it classified as an insight now?

Thankfully, the rules of secrecy are firmly in mind.

Never say what you shouldn't say. Never ask what you shouldn't.

Even if he knew about these things, he would rot in his stomach, and he would never say it.

"Pei Lan, how are you?" Du Yande asked curiously.

"I'm also a member of the 220 Institute now. Test pilot. Pei Lan replied cautiously.

"But, how did you get to the land airline?"

"I didn't go to the Army. I studied helicopter piloting at HNA. ”

"You're still going to HNA?"

"Yes. ”

Wang Buyan was confused.

Army Airlines and Hainan Airlines, they should be two different units, right?

Can Pei Lan switch between them freely? Ordinary people can't do it. Could it be that Pei Lan also has a big background?

However, if she has a big background, she doesn't need to be forced to retire, right?

Strange, always feeling that something is wrong

Soon after, someone arrived by car.

The leader is the commander of a certain regiment of the Army Airlines, called Cheng Xiaoshan. A small black and skinny man.

It is said that pilots of the Army Aviation have high physical requirements and cannot exceed the standard.

It seems to be like a hill, up to 120 pounds.

But in TV and movies, there are a lot of fat pilots of the US imperialists.

It is estimated that their engine performance is strong, the fuel cost is low, and they are not very sensitive to the weight of dozens of catties or something.

"Captain Du!"

"Become the head of the group!"

Everyone greeted them warmly.

Wang Buan stumbled upon an acquaintance.

Who?

Pu Qian City.

Director of the 775 Research Institute.

is specialized in fire control systems. Strange, how did he get here?

What is there in the Army Aviation Regiment that requires a fire control system specialist to come out in person?

He can't even be in charge of the fire control system of the Army Airlines, right?

"I'll just say, it must be you Wang Buan!" Pu Qiancheng also found Wang Bu'an at first sight, and shouted excitedly, "Except for you, no one can make such a big move!"

"Why are you here?" Wang Buan also said unexpectedly, "Don't tell me, you're going to get a helicopter?"

"There are some minor problems with the Wuzhi 9 weapon suspension system of the Army Airlines"

"Oh. ”

Wang Buan shut up knowingly.

The first article of the confidentiality code is that you should not ask what you should not ask. Knowing too much is not a good thing.

After a greeting, they are all acquaintances, so it will be easy to do.

Wang Buan shook hands with Cheng Xiaoshan.

Of course, Cheng Xiaoshan also knows about the 220 Institute.

Now the 125 engine, but it is very sought-after.

It's a pity that the helicopter can't be replaced with a 125 engine. Otherwise, Lu Airlines will definitely have to find a way to get a batch.

"Chief Engineer Wang, what kind of treasure are you experimenting?" asked Cheng Xiaoshan.

"Turboshaft engines. Wang Buan replied honestly.

"Our land flight?"

"Pretty much. ”

"How's it going?"

"Today was just the first test. The climb height is ok. It can exceed 10,000 meters. ”

"That's good, that's good. ”

Cheng Xiaoshan rubbed his hands excitedly, feeling that the opportunity had finally come.

Turboshaft engines!

This is the biggest heart disease of the army aviation.

The biggest flaw of domestic helicopters is that they have a bad heart. The engine performance is not strong enough.

Either it's a lack of power.

Either it's a lack of reliability.

Either the stability is not good.

Either you can't climb high. Either the load is not good.

In short, there are all kinds of defects. Until now, there has not been a relatively perfect turboshaft engine.

"Where's your baby?"

"At the airport. ”

The group immediately headed to the airport.

Cheng Xiaoshan looked at the legendary treasure with some doubts

Isn't this a Bell 407?

What is the 220 Institute doing when you get a Bell 407 out?

This guy is completely a private helicopter! The army has no equipment. There are a few in the police department.

"You read that right. That's it. Du Yande said.

"Invited down from an altitude of 11,000 meters?" Cheng Xiaoshan said suspiciously.

"What? You doubt our ability to fight?"

"It's not. To say that the Bell 407 can fly to an altitude of 11,000 meters, I poke myself in the eye!"

"Nonsense. It must have been modified. ”

"You should all ask Chief Engineer Wang. ”

Everyone's attention was focused on Wang Buan.

Wang Buan nodded, "It is indeed transformed." An engine similar to the 125 was replaced. Aviation kerosene is not required. ”

"Don't need jet fuel?"

"No, you don't. ”

"Isn't that an infinite voyage?"

"That's right. ”

"It's amazing, I'll try it!" Cheng Xiaoshan suddenly became energetic.

Regardless of thirty-seven twenty-one, let's control it first.

He was the commander of the Army Aviation Regiment, and his flying skills were naturally quacking.

What do you want for two-seater driving.

He alone is more than enough.

The Bell 407 flew lightly.

It rises almost vertically. The rate of rise is also very fast.

After a few minutes, it completely disappeared from everyone's sight.

Three thousand meters

Four thousand meters

5 thousand meters

Air defense radars showed that the altitude of the Bell 407 soon climbed to more than five thousand meters.

It can be seen that Cheng Xiaoshan's technique is much more slippery than Pei Lan!

After all, Pei Lan is a cross-border and a halfway monk. Others started playing with helicopters before they even joined the army.

6,000 meters!

Seven thousand meters!

Eight thousand meters!

The height of the Bell 407 continues to climb.

This altitude is already beyond the ceiling of all helicopters in the world.

Many helicopters have a theoretical climb of around 6,000 meters. But after it really flies, it is generally discounted. Often they are only more than 4000 meters.

If it weren't for his personal control, Cheng Xiaoshan couldn't believe it.

He repeatedly checked with the ground radar to see if he was at the wrong altitude.

As a result, the ground-based radar told him with certainty that nothing had gone wrong.

His current altitude is 8,000 meters.

But

The powertrain is too rich.

There are still 50 of the power that is not used. It's terrifying.

"Chief Engineer Wang, what kind of engine did you replace it?" Pu Qiancheng said in surprise, "How much power does it output?"

"Ten thousand kilowatts. Wang Buan said in a low voice, "That is, more than 13,000 shaft horsepower." ”

"What? are you crazy?" exclaimed.

"What's wrong?" Du Yande hurriedly asked.

"This kid," Pu Qiancheng wanted to speak again, "It's too exaggerated, it's too exaggerated." ”

"How do you exaggerate the law?" Du Yande asked in wonder.

Pu Qiancheng told the data.

Du Yande was also dumbfounded.

It's an exaggeration.

It's still a very exaggerated one.

More than 13,000 axle horsepower? This is the engine of the Mi-26 helicopter!

What is someone Mi 26?

It's the largest and heaviest helicopter in the world!

The maximum take-off weight of others has reached 56 tons! It can almost carry a light tank!

If there is any helicopter that is bigger than the Mi-26, it is the short-lived Mi-12 super-heavy helicopter of the former Soviet Union. The maximum take-off weight reached 105 tons!

However, only two prototypes of this Mi-12 helicopter were produced. Then there was no follow-up.

It is estimated that the body size is too large and the cost of use is too high.

The cost of using the Mi-26 is already very high, let alone a superfortress like the Mi-12?

Burning dozens of tons of aviation kerosene in an hour, who can stand it?

What helicopter is Bell 407?

Light!

The maximum take-off weight is only 4 tons!

As a result, you Wang Bu'an now put a Mi-26 storm bear heart on it?

Isn't this a rubber raft to be nuclear-powered?

Can a rubber raft withstand it?

What a pitiful number of recommendation votes please a little recommendation vote, thank you.
