Military Technology

Compared with the previous launch missions, everyone seemed to be more relaxed this time for the landing mission of the intelligent lunar surface exploration experimental vehicle of "Wangshu No. 2". This is also because the entire landing process is controlled by the system. Unless a system error or equipment failure is detected, the command and control center here will take over and manually issue instructions to remotely control the intelligent lunar surface detection experiment of 'Wangshu No. 2' The car makes a landing.

Under normal circumstances, there is no need for human intervention at all, and everything is automatically controlled and executed by the system along the designed program.

Seeing that the numbers in the countdown bar on the big screen are getting smaller and smaller, everyone's originally relaxed mood has become a little bit nervous.

There is no way, no matter who it is, they will not be indifferent when they encounter such a task, so at this moment everyone's ups and downs are normal reactions.

Ten, nine, eight, seven...three, two, one~!

Everyone silently recited the countdown, and then stared at the picture on the big screen.

The simulation screen shows that the 'Wangshu No. 2' intelligent lunar surface exploration experimental vehicle and the orbiter assembly have been separated. But now we have to wait for the data from the orbiter and the intelligent lunar surface detection experimental vehicle of 'Wangshu No. 2' to be transmitted back to confirm.

clap clap clap...

A burst of applause resounded in the hall, and the monitor screen on the orbiter came from the big screen. From the monitor screen, we could see that the 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle had been separated from the orbiter, and then slowly moved away from the orbiter. , falling towards the moon.

As for the orbiter, after it is separated from the lunar rover, it will re-ignite the engine, adjust the orbit, and start flying around the moon. No. ' and 'Wangshu No. 2' intelligent lunar exploration experimental vehicles provide a series of services such as information transfer, navigation and positioning, and lunar remote sensing.

It is worth mentioning that the 'Wangshu-2' intelligent lunar surface exploration experimental vehicle adopts a fast landing technology, which shortens the entire landing time from the previous ten hours to the current few hours. The entire landing process. The base salary is the ballistic curve, so there are higher requirements for the performance of the entire aerial crane.

Like the Wangshu-1 intelligent lunar inspection rover, the 'Wangshu-2' intelligent lunar surface detection

The vehicle inspection also uses aerial crane technology for landing. Compared with the previous generation of aerial crane technology, the second-generation aerial crane technology has been greatly improved and optimized in many aspects, which also enables it to achieve fast landing tasks and shorten the entire landing time to a few hours.

And this technology will also conduct preliminary technical verification tests for a series of subsequent lunar exploration missions and even manned lunar landing missions. Once successful, they will be able to establish a complete set of lunar rapid landing and lift-off technologies in the future, which will be very beneficial to their subsequent series of lunar projects.

It is precisely because of this that Wu Hao and the others did not leave, but prepared to stay at the Xinyuehu command and control center to watch the entire landing process.

On the big screen, in addition to the real-time images captured and transmitted by the 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle and the external monitoring camera on the aerial crane assembly, there are several simulated images showing the entire landing process. , and the real-time status of the combination of the intelligent lunar surface detection experimental vehicle and aerial crane of 'Wangshu No. 2'.

Through these pictures, Wu Hao, Zhang Jun and the others can also see what state the 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle and aerial reversing combination is in, and where it has flown.

As the 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle and the aerial crane assembly got closer and closer to the lunar surface, until about 18 kilometers away from the lunar surface, the aerial crane began to release 'Wangshu No. 2' The intelligent lunar surface detection experimental vehicle, with the release of the cable, the 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle was suspended at the position of about ten meters from the aerial crane. Several engines of the aerial crane were also ignited one after another, and began to work The entire lunar landing complex decelerates.

As multiple engines on the aerial crane were ignited and started, the speed of the entire landing complex was also decreasing, gradually from the initial 1,700 meters per second to two meters per second.

After the entire landing assembly landed to a position of 200 meters above the ground, the aerial crane suspended the intelligent lunar surface detection experimental vehicle of "Wangshu No. 2" and began to hover. At this moment, the descending speed of the landing assembly was zero.

They're like helicopters hanging down

Like a jeep and then hovering over the landing site.

This is the most critical and essential step in the entire landing process, that is, the ground obstacle avoidance system on the aerial crane will be activated, and the ground will be quickly scanned, and a relatively flat location that meets the landing conditions will be selected for landing to avoid The entire 'Wangshu No. 2' intelligent lunar exploration experimental vehicle landed in a crater on the moon. You must know that the crater on the moon is still very high.

Isn't there a comedy movie about a man who falls into a transport crater on the moon, misses the spacecraft to return to Earth, and then gets stranded on the moon.

The whole hovering lasted for five or six seconds. After determining a suitable landing point, the aerial crane suspended the intelligent lunar surface exploration experimental vehicle of "Wangshu No. 2" and began to descend again, and landed to the selected landing point.

Through the images transmitted by the surveillance camera on the intelligent lunar surface detection experimental vehicle of 'Wangshu No. 2', everyone in the Xinyuehu Integrated Space Command and Control Center can clearly see some craters and large craters on the lunar surface. Stone Shadow~www.readwn.com~ At this moment, it has reached the last step of the entire landing process, and everyone's heart has been mentioned in the throat.

which is

It is the high-speed data transmission technology used, and the transmission of signal data is still unstable during the entire landing process, so the pictures everyone sees are also somewhat stuck, and there is no delay.

Under everyone's attention, in the picture, the 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle is getting closer and closer to the ground, until the 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle is stably landed on the moon.

At that moment, the wire rope hanging on the 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle was disconnected, and the aerial crane immediately flew after losing the weight of the 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle. to the distance.

Its task has been completed, and what awaits it will be a magnificent curtain call.

It will eventually hit the lunar surface 100 meters away, and then provide fresh deep lunar soil samples for the follow-up 'Wangshu-2' intelligent lunar surface exploration experimental vehicle.

This was also verified by the camera on the aerial crane. It first flew away from the "Wangshu No. 2" intelligent lunar surface detection experimental vehicle, then descended rapidly, and finally lost the picture.
