"Start landing!" Chen Wenhao shouted, turned on the output power of the spacecraft engine to the maximum, and allocated all the extra energy to the flight attitude stabilization module.

Several spacecraft have already set up data links to communicate on the way to each other, and the spacecraft will not only keep a safe distance from each other, but also learn the flight methods and parameters from the leading spacecraft. Therefore, as long as the spaceship led by Chen Wenhao can land smoothly on the gentle slope, the other spacecraft will basically have no problems.

Although Chen Wenhao has enough confidence in alien black technology, but under this bad weather conditions, he still decided to let his spacecraft try to land first, and he has the protection of the surveyor here, which is equivalent to an extra insurance compared to other spaceships. So, before starting to land again, he sent a message to the other spacecraft, asking them to wait in the surrounding airspace, ignoring the various reactions sent by the other spacecraft, and followed the spacecraft into the space below without hesitation.

This action made Captain Wu and another soldier awe-inspiring, and for the soldiers, what they valued most was the heroism of the man. Moreover, for a leader, shouting "rush me" in times of danger is naturally more worthy of others to follow than shouting "rush to me".

With the position of the height display on the tablet, the ship began to descend at a constant speed of 22 meters per second. Suddenly, the ship plunged down without warning, descending at a rate of more than 40 meters per second!

"Beware! Downdraft! As soon as Captain Wu's reminder was shouted, the next second, the spacecraft stabilized its flight attitude and speed, and resumed its descent speed just now. This makes his loud cue a bit like the shouts of amusement park roller coaster passengers. The atmosphere inside the spaceship suddenly became so awkward...

Facing the four curious and slightly confused eyes from the left and right sides, Chen Wenhao explained, "The intelligent control module of the spacecraft has a self-learning function, and after being affected by a downdraft just now, it has already generated a response mode, so don't worry about it next." In addition, it will also transmit the results of its learning to other ships, and at this point the other ships have also learned how to withstand sudden air currents. ”

"How can you do this?" Captain Wu feels that today's three views have been refreshed. One of the reasons why it is recognized that helicopters are difficult to fly at low altitudes in mountainous areas is that the valley effect causes abnormal changes in airflow, and the rising and falling airflow is completely different on different slopes, which has both dynamic and thermal reasons, affecting both horizontal and vertical airflow.

For example, when the airflow passes through the mountain range, most of the airflow is forced to cross the mountaintop, creating an updraft on the windward side and a downdraft on the leeward side. The strongest of this updraft occurs on the slopes of the mountains hundreds of meters from the summit, and the higher the mountains, the farther the distance they are affected.

If you are a novice pilot, because you can't grasp this sudden airflow, you are likely to be instantly pulled up or down by the airflow, causing the propeller to stall, and the final result is: ah~ah~bang~!

Therefore, in the military, one of the flying skills that helicopter pilots must master is to fly at low altitude in the valley, and now it can be learned in an instant by a machine.

Captain Wu stared at the boss and stared at the control tablet tightly, as if he could see a flower from above. After struggling for a few seconds, he said with some hesitation, "If you descend further, you will encounter mountain turbulence." I won't say, what kind of smart module of yours can also be learned, right? ”

"yes." Chen Wenhao replied.

Ice......

During a brief awkward conversation between the two, the spacecraft had landed at a height of only a few dozen meters away from the gentle slope, and the spaceship, which had been flying steadily in the wind before, suddenly vibrated several times in a row before returning to stability.

This is supposed to be the turbulence of the mountains, which is the friction of the air flow on the slopes of the mountain due to friction. Not only does this vortex stick to the hillside, but when it is on the leeward slope, it can also cause turbulence over the summit and leeward slope, and the wind will be much stronger than on the windward slope.

That's right, the gentle slope on which the trapped tourists are located is the leeward slope, and today's bad weather bonus has caused the valley effect and mountain turbulence to react violently, so the military helicopters piloted by the military elite are helpless.

The spacecraft continued to descend, and shook violently a few more times, and when it stabilized again, Chen Wenhao glanced at the tablet and said, "Okay, the response mode has worked." The mountain turbulence here is really strong, and it took me two studies to get used to it. ”

Captain Wu had the urge to scold the street......

The ground was already within reach, and the spacecraft's detection system was firing at full power, scanning the gently sloping terrain back and forth. Chen Wenhao frowned, "The terrain is uneven, this problem is not big." The trouble is that there are not many open spaces to land, and only four ships can be parked at most. I'm going to send a message for them to come down in two batches. ”

In the next second, there was a slight vibration from the bottom of the spaceship, and the spacecraft had landed safely on a gentle slope. Due to the terrain constraints of the gentle slope, the spacecraft needs to maintain balance and cannot be fully docked on the ground, and the bottom one-third of the position is suspended, relying on the attitude adjustment module to maintain the overall balance. The rear-opening hatch opened, and the wind rushed into the ship with the rain.

Captain Wu didn't even have time to sigh that the spacecraft landed so easily, and as soon as the hatch opened, he rushed off the spacecraft with another team member against the wind and began to organize the retreat of the on-site personnel. Chen Wenhao told him a request, "Quick! "The ship's engines are still running at high speed to withstand the impact of the wind, and the power consumption is huge, so you need to hurry.

……

The ship's own light penetrated the night and the rain curtain, allowing the trapped on the gentle slope to clearly observe its trajectory, and in full view of everyone, the spacecraft successfully landed on the gentle slope, and the howling wind could not hide the shouts from the crowd, which was a fluke when desperate to find a way out, mixed feelings.

The trapped people who still had physical strength began to spontaneously move closer to the ship's stoppage, which was the only source of light in the night. Xu Zhiming was also one of them, he didn't exercise much on weekdays, he mustered up his last physical strength, and stumbled towards the spaceship that looked very warm, closer, just ahead. Damn, I just want to go home, and I don't want to see any dangerous distances anymore.

The two team members who had absolved here from the helicopter had rushed to the spacecraft first, and they were already guarding the periphery of the trapped crowd, which was the closest to this side, and their physical strength was much better than that of others, so they naturally came the fastest. "Captain!" The shouts of the two were blown away by the wind, and they were not sure if Captain Wu had heard them. Even if they are tough guys, the hearts of the two of them are also full of joy at this moment, although they have been comforting the masses before, promising that the troops will come to the rescue in time, but as the wind and rain are getting bigger and bigger, their professionally trained mood has fallen into a trough, in this case, the helicopter is difficult to count on. It's just that I didn't expect the captain to come to us with such a big guy.

Although Captain Wu didn't hear what the two were saying, it didn't affect him to slap both of them on the shoulder, they were both good soldiers. However, this was not the time to catch up, he gave them the high-powered tactical flashlight he brought, and gave the order with gestures to immediately create a quarantine zone near this clearing, and then there were other ships to land. Soon, the four servicemen were spaced a few steps apart from each other, blocking the road between the trapped crowd and the space.

The fastest to arrive at the traps had already approached......
