Pet King

Zhang Zi'an hasn't expressed his position for the time being, and has been thinking about the solution of the best of both worlds. It would be nice if he could find a solution that is safe and can save everyone's physical strength.

But he couldn't think of a better way.

The safe way to climb the sandy ridge was proposed by Professor Wei Kang last night. When Lippit ’s team provided the opportunity of satellite Internet access for free, others were chatting or writing emails, while Zhang Zi'an searched the Internet for the method ——After all, it's about security. He can't follow blindly.

As a result, he found that Wei Kang's method was not original, but the conventional practice of oil exploration workers in the desert.

This is troublesome, very troublesome.

The methods that oil exploration workers have concluded through practice and exploration must be the result of experience and wisdom.

The wisdom of the people is endless. On his own, he entered the desert for the first time. Where can he confidently come up with a better solution?

Oil exploration workers can adopt this method because their physical strength, will and endurance are far beyond the level of ordinary people. The scientific research team can't compare with others, even Lippit's team can't compare. People.

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

Zhang Zi'an looked at the suitcase with the drone.

Can you use drones to improve one of them?

If you use a drone to look at the landform in the air and find a gentle slope, will you not need to climb the sand dunes yourself?

He thought about it, and felt that this approach seemed feasible.

Drones cannot completely replace human eyes, because people's eyes produce stereo vision, walking on sandy ridges, the **** can be seen at a glance or not, and drones need to find a suitable shooting angle and height along the Flying over a sandy ridge, the visual judgment of the **** may not be accurate, but in any case, you can save yourself from running around. Don't move your feet if you can use your brain.

"Wait, don't make a noise, I have a proposal."

Thinking about it, he said his thoughts on the intercom public channel.

The people sitting besides Nabari and Salem were all highly educated people, and he understood what he meant at first sight.

"Did you also bring a drone?" Lippit said in surprise.

"Yes!" Wei Kang's tone of excitement said, "This method is great! I think it's okay, although the drone may not find the gentlest slope, it only needs to be relatively gentle."

Lippit sighed with regret, "We originally brought drones, but were seized by the customs when we entered the country, saying they were dangerous goods and we couldn't bring them in."

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

The scientific research team was able to bring in the drone smoothly because of the official documents stamped by Binhai University and the official invitation letter from Cairo University. Lippit and their gang of gods did not have these procedures. Their drone was customs The detention was not unexpected.

Everyone thinks this method is feasible. The atmosphere of the gunpowder public channel was reversed. Several people joked about Zhang Zi'an why they hadn't thought of it before, which caused everyone to use their hands and feet to climb a dune.

Can the drone support the long-term work under the high temperature and direct sunlight? Zhang Zi'an is at ease, worried that the drone will be damaged.

Wei Kang was also unsure, but now is not the time to consider these, and choose between the team facing splits, morale setbacks and the possibility of damage to the drone, only the latter.

Zhang Zi'an got out of the car, opened the suitcase on the hot hood, and began to assemble the drone under the hot sun.

Everyone is praying that this method will be successful, otherwise morale will be too bad, and hope will be faced and disappointed.

The battery is full, all parts are well maintained, and the drone self-checks everything is OK.

On the wings of the drone, "Nehbet" was written with a marker, which was the name Fina gave it, the goddess of sky in ancient Egyptian mythology, and a female falcon.

Hope it can really dominate the sky like this name.

Zhang Zi'an took the remote control back to the car and gave instructions for taking off.

Nehbet's four propellers spin at high speed, flying briskly into the sky, reflecting the silver light under the sun.

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

"Xiao Zhang, hold on! Don't fly too low!" Wei Kang reminded with a walkie-talkie, pinching sweat for the drone.

"I know, rest assured."

Zhang Zi'an calmly manipulated the drone to fly directly above the dunes, and the remote control screen displayed the real-time picture taken by the drone.

"There's a big difference here, but fortunately, we rushed to the car without risking ..."

Seeing the scene behind the dunes ~ www.wuxiaspot.com ~ He took a breath, because this dune was facing them with the windward side, although the **** was not exaggerated, so the scientific expedition team members had The idea of ​​rushing straight up, but the leeward side of the dunes is often steeper than the windward side.

Although it is impossible to measure accurately, the leeward angle of this dune is almost 30 degrees.

30 degrees may not seem high at first, but it is already quite steep, and the maximum angle at which sand particles can remain stationary on the dunes is about 35 degrees. A 30-degree dune cannot be compared with a 30-degree paved road. The tires cannot support the sand ridge. If the vehicle passes the sand ridge a little faster, it will fly straight out and turn into the sand.

Zhang Zian operated the drone to maintain a fixed height, and flew along the sandy ridge, letting the camera look down at a 45-degree angle to find a suitable crossing point.

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

Although the desert environment is open and free of interference, and the remote control distance is very long, Zhang Zi'an did not dare to fly it too far, almost let it return the same way. On the way back, observe those alternative locations again, and then choose the smoothest visual inspection One place, let the drone hover over there as a marker.

Zhang Zi'an sent a signal through the walkie-talkie, and everyone started the car one by one and drove to the location where the drone was.

When everyone was in place, he quickly let Nehbet land and retract it into the car. At this time, its casing was hot enough to scorch out the hands, and the battery was so hot that it would suddenly explode. .

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

Other cars also successfully over the sand dunes.

With the use of Daxianweiwei's drone, the most troublesome problem so far has finally been solved.
