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 only a few countries. Many countries are eager to try and want to use this to land on the moon to show themselves.
The strength of the country, but without exception, all failed. Of course, according to their logic and propaganda, it can be considered a success. After all, their probe did reach the moon and landed on the moon. But compared to the previous
The soft landings of those rockets were just hard landings. They were very unenvironmentally friendly. Not only did they create a big crater on the moon, but they 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.
Previous lunar probes from those countries basically used a combination of detectors and patrollers. 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 patrol unit being often very small. Because of this, the power of the antenna on the patrol unit is relatively small, and the detector can only be used for mid-range detection.
Relay communications. Some even rely on satellites in lunar orbit for 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.
It is the heaviest vehicle on the moon, including the ride vehicle 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 called a black technology "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 sky crane attracted the attention of the world as soon as it was unveiled. Because the concept and technology are relatively advanced, it is called NASA
One of the black technologies.
Because of this, NASA keeps this technology strictly confidential, and it is impossible for outsiders to steal it. Therefore, although Wu Hao and his intelligent lunar surface patrol and exploration vehicle also use "aerial crane" technology, this
The technology is indeed developed from scratch.
In other words, this time, they will use aerial crane technology for the first time to land this three-ton intelligent lunar surface patrol rover on the moon. 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 patrol and exploration vehicle breaks away from the lunar orbiter and prepares to start landing, the aerial crane mechanism will start to work. It must first control the entire intelligent lunar surface patrol and exploration vehicle and the
The posture of the aerial crane assembly allows it to land according to 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 drops to a certain height, the intelligent lunar surface patrol rover and the space crane assembly begin to separate.
, the space crane released the rope, and the intelligent lunar surface patrol and exploration vehicle was suspended and prepared for landing.
During this process, in addition to continuously decelerating, the space crane must also control the attitude of the entire landing assembly to ensure that it lands in a correct attitude. In addition, the space crane must also 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.
No way, the intelligent lunar surface patrol and exploration vehicle does not have a special 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 ropes and cables cannot be cut off accurately, it is likely that the intelligent lunar surface inspection 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 surface.
Patrolling the top of the rover will cause the entire rover to be scrapped and the mission will fail.
From the separation from the lunar orbiter and the landing to the final steps of flying away and falling, the entire process lasts far longer than the several landing missions that NASA has performed on Mars. This is the work of the aerial crane.
The longer the time, the higher the technical difficulty will naturally be.
It is precisely because the technical requirements are very demanding that it is regarded as NASA's black technology. Now Wu Hao and others have mastered this black technology and created our national version of aerial crane black technology with their own understanding.
This has also made the public extremely excited, and everyone is eagerly 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 inspection vehicle is also a hot topic of everyone's attention. No country or even company has ever been able to send this 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. Such a huge mission can be said to be something that everyone is looking forward to. Because previous lunar explorations
The distance that the detector and the patrol vehicle can move is really too close, so everyone hopes to see more scenery on the moon and detect more useful data through this intelligent lunar surface patrol and exploration vehicle.
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?
