Compared with the first flight show of the Jianmu-7 retractable launch vehicle, which debuted for the first time, more attention has been focused on this intelligent lunar surface patrol and exploration vehicle.

You know, the countries in the world that have the ability and success to send probes to the moon can be counted on one hand. So far, there are just a few countries. Many countries are eager to try to land on the moon to show their country's strength, but without exception they have failed. Of course, judging from their logic and propaganda, it can be considered a success. After all, their probe did reach the moon and landed on the moon. It's just that compared to the soft landings of the previous rockets, what they used was a hard landing. It is very unenvironmentally friendly. It not only made a big crater on the moon, but also scattered garbage everywhere.

You are very unethical. What should you do if you smash flowers and plants? Although there are no flowers and plants on the moon, it is not bad if you hit sand and rocks.

The previous lunar probes of those countries basically used a combination of detectors and rover. The advantage of this approach is that the technology is relatively mature, the structure is relatively simple, and it is more reliable and safer.

The disadvantage, of course, is that the detector takes up too much load, resulting in the size and weight of the rover being often very small. Because of this, the power of the antenna on the patrol device is relatively small, and the detector can only be used for relay communication. Some even rely on satellites in lunar orbit to relay communications.

It is precisely because of this that the rover cannot be too far away from the landing detector, which greatly limits the detection range of the rover.

The intelligent lunar surface patrol and exploration vehicle of Haoyu Technology does not have a landing detector. Its main body is an intelligent lunar surface patrol and exploration vehicle. The entire vehicle is nearly three tons. It can be said that it is the largest lunar surface patrol and exploration vehicle so far. The heaviest vehicle on the moon, including the ride used by astronauts who landed on the moon decades ago.

What brought this nearly three-ton intelligent lunar surface patrol and exploration vehicle to the moon smoothly was a black-tech "aerial crane" from NASA, which can also be called a sky crane.

NASA used this kind of sky crane to smoothly send several great exploration vehicles to Mars. This kind of aerial crane attracted the attention of the world as soon as it was unveiled. Because the concept and technology are relatively advanced, it is called one of NASA's black technologies.

Because of this, NASA keeps this technology strictly confidential, and it is impossible for outsiders to steal it. Therefore, although Wu Hao's intelligent lunar surface patrol and exploration vehicle also uses "aerial crane" technology, this technology was indeed developed from scratch.

In other words, this time, they will use aerial crane technology to land this three-ton intelligent lunar surface patrol rover on the moon for the first time. This should be said to be the first time humans have used this technology to land on the moon. detector.

There are many reasons why this is not applicable. Although the moon has a relatively small gravity, it is completely in a vacuum, with no atmosphere and no air. Therefore, whether it is taking off or landing on the moon, it must completely rely on thrusters.

This means that when the intelligent lunar surface inspection and exploration vehicle breaks away from the lunar orbiter and prepares to start landing, the aerial crane mechanism will start working. It first has to control the attitude of the entire intelligent lunar surface patrol rover and aerial crane assembly so that it can land on the predetermined trajectory curve.

During the entire landing process, multiple staged decelerations are required to control the landing speed of the entire assembly. When the assembly dropped to a certain height, the intelligent lunar surface patrol and exploration vehicle and the space crane assembly began to separate. The space crane released the rope, and the intelligent lunar surface patrol and exploration vehicle was suspended to prepare for landing.

During this process, in addition to continuously decelerating, the space crane also needs to control the attitude of the entire landing assembly to ensure that it lands in a correct attitude. In addition, the space crane also needs to move in the air to select a suitable landing site.

This is the active obstacle avoidance technology used by other previous probes before landing. However, the descent speed of the space crane is much slower than those of those probes, so the technical requirements are more difficult.

There is no way, the intelligent lunar surface patrol rover does not have a dedicated lander. The collision during the entire landing process needs to be borne by the vehicle itself, so the landing speed must be controlled to ensure the safety of the intelligent lunar surface patrol and exploration vehicle.

As for the aerial crane, it must accurately capture the moment the intelligent lunar surface inspection and exploration vehicle lands, and immediately cut off the steel cables suspending the vehicle, so as to use the last fuel to fly away from the intelligent lunar surface inspection vehicle. The rover then fell to an area hundreds of meters away to avoid affecting the intelligent lunar surface patrol rover.

This action is very critical. If the steel cables and cables cannot be cut accurately, it is likely that the intelligent lunar surface patrol and exploration vehicle will be carried away by the aerial crane and be damaged. It may also cause the aerial crane to directly hit the intelligent lunar lunar surface inspection and exploration vehicle, causing the entire exploration vehicle to be scrapped and the mission to fail.

From the time it separated from the lunar orbiter and started landing to completing the final steps of flying away and falling, the entire process lasted far longer than the several landing detection missions that NASA performed on Mars. This means that the working time of the aerial crane is longer, and the technical difficulty is naturally higher.

It is precisely because the technical requirements are very demanding that it is regarded as NASA's black technology. But now Wu Hao and others have mastered this black technology and created our national version of aerial crane black technology with their own understanding. Find Shuyuan www.zhaoshuyuan.com

This also made the public extremely excited, and everyone was enthusiastically looking forward to witnessing the performance of Haoyu Technology's version of aerial crane technology.

In addition to the lander aerial crane technology, this intelligent lunar surface patrol and exploration vehicle is also a hot topic of attention. No country or company has ever been able to send a three-ton exploration vehicle to the moon.

And according to reports, this intelligent lunar surface patrol and exploration vehicle will ride on the moon for a long time and is expected to travel tens of thousands of kilometers. It can be said that such a huge task is something that everyone is looking forward to. Because the distance that previous lunar probes and patrol vehicles could move was too close, everyone hopes to see more scenery on the moon and detect more useful objects through this intelligent lunar surface patrol vehicle. The data.

Therefore, not only the public, but also scientists are full of expectations for this intelligent lunar surface patrol and exploration vehicle.

Now there is a question that has been bothering everyone, that is, until now, Haoyu Technology has not announced the code name of this intelligent lunar surface patrol and exploration vehicle. What is its name?
