Chapter 1235: Showing His Power

Zhang Zian didn't express his opinion for the time being, and has been thinking about a solution that has the best of both worlds in his heart. It would be great if he could find a way that is both safe and able to save everyone's physical strength.

But he couldn't think of a better way.

The method of crossing the sand ridge safely was proposed by Professor Wei Kang last night. When Li Pitt’s team provided free access to the satellite Internet, others were chatting or writing emails, and Zhang Zian searched the method proposed by Wei Kang on the Internet. ——After all, it's about safety, he can't follow blindly.

As a result, he found that the method proposed by Wei Kang was not original, but a common practice of oil exploration workers in the desert.

This is troublesome, very troublesome.

The methods summed up by oil exploration workers through practice and exploration must be the crystallization of experience and wisdom.

The wisdom of the masses is boundless. How can he have the confidence to come up with a better solution when he enters the desert for the first time by himself?

The oil exploration workers can adopt this method because their physical strength, willpower and hard work are far beyond the level of ordinary people. The scientific expedition team is incomparable to them, not even Lipett's team people.

Therefore, this method may not be applicable to his own team, at least it cannot be copied intact.

Zhang Zian glanced at the suitcase containing the drone.

Can drones be used to improve one of these links?

If you use a drone to fly in the air to look down on the landform and find out where the slope is gentle, will it save everyone from climbing up the sand dunes?

He thought about it, and felt that this method seemed to be feasible.

UAVs cannot completely replace human eyes, because human eyes produce stereoscopic vision. Walking on sand ridges, you can tell whether the slope is gentle or not at a glance, and UAVs need to find a suitable shooting angle and height along the sand ridge. Flying over sand ridges, the visual judgment of the slope may not be very accurate, but it can save everyone from running around anyway, and don’t move your feet if you can use your brain.

"Wait a minute, stop arguing, I have a proposal."

After thinking about it, he said his thoughts on the public channel of the walkie-talkie.

Among the people sitting there, except for Nabari and Salim, they were all highly educated people, and they understood what he meant when they heard it.

"You guys also brought drones?" Lipett was surprised.

"Yes!" Wei Kang's tone was full of excitement, "This method is great! I think it's no problem, although the drone may not find the place with the gentlest slope, as long as it is relatively gentle."

Li Pitt sighed regretfully, "We also brought drones, but they were detained by the customs when they entered the country. They said they were dangerous goods and could not be brought into the country."

The severe anti-terrorism situation in Egypt has made the customs' control of drones very strict. Forget about toy drones. If it is a high-performance drone, the authorities are very worried that it will be used to carry out terrorist operations.

The scientific expedition team was able to bring the drone in smoothly because of the official documents stamped by Binhai University and the official invitation letter from Cairo University. Lipett and his gang of magicians did not have these procedures, and their drone was confiscated by the customs. The withholding was no surprise.

Everyone felt that this method was feasible, and the atmosphere of the public channel, which was full of gunpowder, was reversed. Several people half-jokingly complained to Zhang Zian why they didn't think of it before, and everyone climbed a sand dune with their hands and feet.

Zhang Zian was not sure whether the drone could survive working under high temperature and direct sunlight for a long time, and was worried that it would damage the drone.

Wei Kang is not sure, but now is not the time to think about these things. To choose between the possibility of splitting the team, demoralizing the morale, and damaging the drone, he can only choose the latter.

Zhang Zian got out of the car, opened the suitcase on the hot hood, and started to assemble the drone under the scorching sun.

Everyone is praying that this method will be successful, otherwise it will be too demoralizing, and they will face disappointment just as they have hope.

The battery is full, all components are in good condition, and the self-test of the drone is normal.

On the wing of the drone, "Nahbet" is written with a marker,

This is the name Fina gave it. It is the goddess of the sky in ancient Egyptian mythology, a female falcon.

Let's hope it really rules the skies like the name does.

Zhang Zian returned to the car with the remote control and gave the command to take off.

Nakhbet's four propellers rotated at high speed and flew briskly into the sky, reflecting silver light under the sunlight.

Everyone in the convoy looked up, staring intently at its flight path.

"Xiao Zhang, hold on! Don't fly too low!" Wei Kang reminded through the walkie-talkie, sweating for the drone.

"I know, don't worry."

Zhang Zian calmly steered the drone to fly directly above the sand dunes, and the real-time images captured by the drone were displayed on the remote control screen.

"There's a big gap here, but fortunately we didn't take the risk of driving up directly..."

Seeing the scene behind the sand dune, he gasped, because the sand dune was facing them from the windward side. Although it was high, the slope was not exaggerated, so the scientific expedition team had the idea of ​​rushing up directly. But the leeward side of a dune is often steeper than the windward side.

Although there is no way to measure it accurately, the angle of the leeward side of this dune is about 30 degrees by eye.

30 degrees may not seem high at first glance, but it is actually quite steep. The maximum angle at which sand grains can remain still on the dunes is only about 35 degrees. A sand dune at a 30-degree angle is not comparable to a 30-degree paved road. The tires can’t bear the strength on the sand ridge. If the vehicle speeds up a bit when crossing the sand ridge, it will fly out directly, turn over and plunge into the sand.

Zhang Zian operated the drone to maintain a fixed height, and flew along the sand ridge, letting the camera look down at a 45-degree angle to find a suitable place to climb over.

After flying for a few minutes, the drone flew over several alternative locations from above.

Although the desert environment is open and undisturbed, and the remote control distance is very long, Zhang Zian didn't dare to let it fly too far, so he almost let it go back the same way. On the way back, he looked at the alternative locations again, and then chose the one that was the most peaceful by visual inspection. Let the drone hover over there as a marker.

Zhang Zian sent a signal through the walkie-talkie, and everyone started their cars one after another and drove towards the location of the drone.

Once everyone was in place, he quickly let Nakhbet land and stowed it into the car. At this time, its casing was so hot that it could blister your hands, and the battery was so hot that it was worried that it would suddenly explode. .

He verbally described the situation on the other side of the sand dunes, so that everyone had a bottom line, and then he set an example and took the lead in driving over the sand dunes.

Other cars also successfully crossed the dunes one after another.

With the help of drones, the biggest headache so far has finally been solved.
