Landed safely on the outskirts of Barong County.

The large grassland in the suburbs is temporarily listed as a military restricted area.

The helicopters that searched and came back landed here. Substitution. Go on. No pause. 24-hour non-stop search.

The camp is surrounded by police. There are also some local militia units.

The Mi-171 helicopter formation landed in a mighty formation.

Nie Chuan is not there, only Cheng Xiaoshan is there. He had just returned from a search. Looks a little tired.

"What's the situation now?" asked Wang Buan.

"Minister Nie has already led the team into the mountain. Two rounds of air searches were conducted. Not found yet. Cheng Xiaoshan replied regretfully.

"What about the family, do you have any feedback?"

"Nope. ”

The family did not have further details.

The local search and rescue team also had no more information.

Some rescuers speculated that such a vigorous search might end up being a bamboo basket for water.

For travelers, Barong Mountain is really big and big. You can't find it on foot. Luckily, there aren't many roads into the mountains. Search along the road into the mountain, whether there is anyone or not, and in the end it will definitely be able to find out. At present, a rescue command has been set up in the local area to command the search and rescue in a unified manner.

Thanks to the large number of helicopters, the search and rescue work has become easier.

All the search and rescue personnel are traveling by helicopter. The entry and exit of the mountain are transported by helicopter. The same goes for logistical supplies.

The first wave of search and rescue was along the main road into the mountain.

In addition to the low-altitude search by helicopter, there are also local guides who go down to the ground to search on foot. Special additions have also been made to key areas.

From a technical point of view, it requires repeated take-off and landing of helicopters.

It is necessary to repeatedly search for relatively flat land and put the search and rescue personnel down.

At night, the search and rescue personnel had to be picked up repeatedly.

Easier said than done.

Compared with Huangshan, the meteorological conditions of Barong Mountain are much more complicated.

The mountains are steep, the dangerous peaks are towering, and the airflow is very complicated. There is no way to predict the direction. There is no way to predict the intensity. Strong winds come as they say, and leave as they say.

Cheng Xiaoshan is a super old bird, and the first time he entered the mountain, he was almost blown around by the sudden mountain wind.

Fortunately, it was the ZM-100 turboshaft engine that gave power. Great afterburner. Get out of trouble now.

"Fly up. ”

"If there is an accident, immediately fly upwards. ”

Cheng Xiaoshan repeatedly emphasized.

There is only one lesson he has summed up.

Relying on the powerful power of the ZM-100 engine, it explodes directly upwards and then gets out of trouble.

The ZM-100 is so powerful that there is no resistance to falter it.

As soon as the power output is forcibly pushed above 50%, it will swoop upwards.

Generally speaking, as long as you jump a few hundred meters quickly, you will be able to escape the strong wind. Then it's relatively safe.

If you really can't, you just fly to an altitude of 8,000 meters. It's definitely going to be fine.

"Don't do anything else!"

"Remember not to sway back and forth, from side to side. The valley is too narrow. Easy to hit. ”

Cheng Xiaoshan emphasized again and again.

These are flying tricks. It has nothing to do with Wang Buan. He just listened.

In fact, all helicopters are equipped with SAF flight assistance systems. In case of danger, it will automatically take over the helicopter.

It automatically determines the situation around it and makes quick decisions to pull the helicopter up.

That's right, its operation is the same as Cheng Xiaoshan's reminder.

It's all about flying as much as you can.

The powerful power of the ZM-100 turboshaft engine is the best guarantee to get out of the predicament.

Even with only 10% of the oxygen content on the ground, it can fly upwards smoothly.

If the helicopter is in danger three times in a row, it will automatically turn back.

It will choose to land on flat ground nearby.

If there is no such system, Wang Buan will not dare to rest assured!

If any pilot accidentally crashes and crashes, he will be held responsible. He certainly couldn't take such a risk.

But the SAF system is not to be disclosed for the time being.

The information fed back from the Air Force, this system is better not to be explained in advance.

Otherwise, there will be no way to test the psychological state of the pilot.

And for pilots, the state of mind is important.

"Chief Engineer Wang, let's take a look?"

"Good. ”

Wang Buan nodded.

The Mi-171 helicopter took off again.

It took Wang Bu'an to Barong Mountain. A few minutes later, we entered the mountains.

The topography of Barong Mountain is somewhat similar to the mountains around the Grand Canyon of the Brahmaputra River. They are all towering peaks and cliffs. The canyon is deep and narrow, and there is not much room to maneuver.

When encountering danger in such a place, the most feared thing is to sway from side to side, back and forth. It's easy to hit the mountains.

In case you notice that the state is unstable, the best thing to do is to fly upwards.

Sure enough, a short time later, the helicopter began to jolt.

This is caused by disturbed airflow.

Even Huo and his party can't be completely avoided.

Several times, he had to raise his altitude to avoid the turbulent air currents in order to maintain his balance.

However, if you fly too high, you can't search the ground.

This is a paradoxical existence.

I had to rely on repeated searches.

Hopefully, the next time I come in, I won't encounter similar strong winds......

"Click!"

"Click!"

Suddenly, the helicopter paused up and down twice.

But it was another chaotic air current. It seems that there is also rubble hitting the propeller. Then it was chopped.

"Not good!"

"Dangerous!"

Huo Yixing's face changed drastically, and he hurriedly tried to pull up.

It wasn't the air currents that he was afraid of.

He was afraid of sudden rubble.

If the propeller is broken or broken, then it is a big trouble.

Luckily, it's fine.

Get out of danger safely.

"Chief Engineer Wang, are you okay?" Huo Yixing said with palpitations.

"It's fine. Wang Buan nodded casually.

He's not afraid of any gravel.

Want to break the propeller? That's impossible.

It's a grade 5 cemented carbide! It's tougher than any alloy on the planet today.

It is capable of withstanding 30,000 tons per square centimeter.

Even the main guns of tanks can't be broken.

What is a little gravel?

"This place is weird. Huo and his entourage said.

"I've done everything safe. Wang Buan said lightly, "You can fly with confidence." ”

"What measures?"

"I'll talk about it later. ”

"Good. ”

Huo and his entourage quickly returned.

Cheng Xiaoshan gathered most of the pilots to prepare for the lecture.

Wang Buan first introduced the SAF flight assistance system. This system is already equipped on top of the J-17 fighter.

After a brief explanation, it is a test on the spot.

Wang Buyan personally demonstrated.

He doesn't know how to operate a helicopter. Just about.

However, Huo Yixing, Nie Chuan, and Cheng Xiaoshan all refused on the spot. Nie Chuan hugged him directly.

It was impossible for them to let Wang Buan take risks.

Just kidding, how is it possible to let the national treasure of the national treasures go to the sky to go on an adventure?

They prefer to come on their own.

In the end, it was Cheng Xiaoshan who went into battle in person.

According to Wang Buan's request, he pulled the helicopter to an altitude of 100 meters. Then let it go......

The helicopter, which lost control, plunged sharply.

"Ahh

"Not good!"

Everyone's faces changed drastically.

If the SAF system doesn't work, it's dangerous.

You know, falling from a height of 100 meters is a matter of seconds. At that time, Cheng Xiaoshan will not have time to react at all.

Fortunately, the helicopter fell sharply about 30 meters, and quickly adjusted its attitude and stabilized.

It flew forward quickly. And began to climb. Rapid climbing.

It climbed to an altitude of 3,000 meters.

"Cheng Xiaoshan, do you have an operation?" Huo Yixing hurriedly asked.

"Nope. Cheng Xiaoshan replied affirmatively.

"Good!"

"Good!"

Huo and his entourage stroked their palms with relief.

Nie Chuan also secretly breathed a sigh of relief. He's a bit stressed.

After all, the topography of Barong Mountain is very complex, and the climatic conditions are very bad. He was very worried that there would be a helicopter accident inside.

Don't go to the end, the traveler did not save him, but sacrificed the search and rescue personnel.

Well, now that worry is gone.

Cheng Xiaoshan repeatedly tried various "out of control" situations.

As a result, each time, the SAF system reacts very quickly. Before the crash, the helicopter was successfully pulled up.

Huo and his entourage went into battle.

Nie Chuan went into battle.

Other pilots were also on the field.

They are also simulating all sorts of "runaway" operations to detect SAF systems.

As a result, SAF systems are very sensitive. If you find something wrong, take over immediately.

After taking over the control of the helicopter, the first action was to raise it to an altitude of 3,000 meters. This gives the pilot enough time to react otherwise.

The most thrilling time, at a height of only five meters above the ground, the helicopters were pulled up.

It was the pilot who was in a brief coma.

But it was a huge overload that left the pilot unconscious.

Thankfully, it was only a brief coma.

A few minutes later, the pilot woke up.

"There shouldn't be anyone out of control at an altitude of three thousand meters, right?" said Wang Bu'an with a smile.

"Definitely not. Cheng Xiaoshan replied loudly.

Joke......

How could such a thing be?

Do you think that the usual training is passable? If you can't even control the altitude of 3,000 meters, is that still a pilot?

"Okay, move on to the next project. ”

"Falling rocks attacked. ”

Wang Buan waved his hand and asked people to move a pile of stones.

An excavator prepares to throw stones onto rotor blades that are spinning at high speed.

At this time, the rotor blades have the highest rotational speed.

"Chief Engineer Wang......"

"Chief Engineer Wang, are you really okay?"

"Chief Engineer Wang, do you want to change to a smaller stone? Feishi doesn't have such a big ......?"

The three senior officers were secretly worried.

The stone prepared by Wang Bu'an seems to be too big?

The average flying stone, that is, the size of a fist. At most, it is the size of a watermelon.

However, the fist prepared by Wang Buan felt like the largest pumpkin. Each of them weighed thirty or forty pounds.

With such a heavy stone falling down, it is estimated that a cow will be smashed flat, let alone a blade?

No matter how tough the blades are, they can't withstand such a heavy attack, right?

What's more, the blades are still spinning at high speed.

"Let's get started!"

"Bang bang bang!"

All the stones were thrown.

Large, chunks of stone, slammed viciously on the spinning blades.

As a result, a dull sound came. Immediately after, there was dust flying in the sky.

Everyone secretly sweated.

It's going to be okay, right?
