Chapter 2147: Return to the ground

A lot of people came to see the recovery together. After all, this was a major historical moment. The spacecraft of the Han Kingdom went to heaven and recovered for the first time!
Except for the space shuttle, which can land at the airport because of its maneuverability, the spacecraft are all going down by parachute. This method will make a considerable change in the landing point, which is a thousand miles away.
However, this is not the first time. Han has launched many returnable satellites before. As long as you master the recovery technology of returnable satellites, you will also master the return technology of the spacecraft. After all, the control of the two is similar. The main reason is that the spacecraft’s return capsule is larger and heavier. At the same time, it requires a lower speed when landing, so when it is one or two meters above the ground, there will be a buffer rocket ignition to further reduce the speed.
Now, when Qin Guan came to the main landing site, the personnel preparing to recycle were already ready.
The best recovery is of course the use of helicopters. For this recovery, four large super stallion helicopters are ready.
These helicopters were also obtained during the exchange of war materials with the Parthian nation. This helicopter has a large carrying capacity. If necessary, it can even be lifted directly back to the cabin. The cabin is wide and the search personnel are ready to go. Next to it, there is a radar car with a flat radar antenna facing the sky above, aiming at the direction of the spacecraft’s return. Once the spacecraft enters the atmosphere, they will find the target the first time.
"This landing site, we will also fix it in the future." Qin Guan communicated with Ren Lao next to him.
On the grassland, it’s already very cold. The north wind is blowing. The cold current from Siberia swept across the land. Wearing a military coat, Qin Guan felt like his face was cut by a knife. In a blink of an eye, Haven't come to Grassland City for another year! Every time I come back here, there is always a kind of cordial feeling, because Qin Guan started from here, and under his leadership, the industrial technology of the entire Han country has also begun to advance by a large margin!
Qin Guan looked at everything around him with great interest.
"What, data injection failed?" At this moment, a message was suddenly received from the communication device on the helicopter.
Everything went smoothly during the launch. It was in orbit normally, and all postures were normal. Now, when it’s time to return, you need to send instructions to the spacecraft to tell the spacecraft where to slow down, throw away the two useless cabins, and then Entered the atmosphere, but at this moment, a bad news came.
If the data injection fails, the spacecraft cannot receive the message and cannot return to the ground. This is really bad news!
"It seems that our Yuanwang survey ship needs to update its equipment." Qin Guan also said, this data injection is operated by survey ships sailing on the ocean. Every time a space launch, these space survey ships They all play a major role. Now, with the launch of the spacecraft, the Yuanwang survey ship needs to be more advanced and modern. A few more should be built. In case something goes wrong, there will be backup supplements. .
"Don't worry, they will find out the cause." Ren Lao said. Regarding his comrades in aerospace measurement and control, Ren Lao is quite assured that they will be able to complete the task.
Qin’s point of view, he is not worried. However, with the development of his own space technology, it is time to upgrade the supporting equipment. This is not just a question of building a space survey ship, if it can lease the territory of another country. , It would be even better to establish several space measurement and control stations on land.
All of these need to be developed.
Two hours later, the news came again. When the spacecraft flew in the next lap, the data was injected normally, and the spacecraft was starting the return procedure!
The spaceship is coming back!
After traveling more than a dozen laps in space, the Shenzhou-1 spacecraft first separated the orbital module, then adjusted its attitude, turned the tail engine around, ignited the brakes, and as the speed decreased, the Shenzhou-1 spacecraft left the original The orbit, along an arc, got into the atmosphere!
As for this orbital module, it will continue to stay in space, become a satellite, and continue to serve the aerospace industry. It will take at least half a year before it falls into the atmosphere and burns.
From this moment on, the recycling base became busy.
There are a total of four super stallion helicopters, each located at the four vertices of a square, and the center of the square is the scheduled landing point. Although there is a radar, it still depends on the eyes of the pilot to find the return cabin.
The vehicles on the ground have also been activated, waiting for orders to come at any time.
The helicopter was pulled up first. Qin Guan, Ren Lao and others took a helicopter and began to hover in the sky, waiting. Suddenly, someone shouted: "Found the target!"
What a sharp eye! The pilot of this helicopter has already seen the black return capsule that is falling rapidly in the sky!
The return cabin first pulled out a small parachute, and the entire return cabin shook for a while and began to slow down. After a few seconds, the small parachute was thrown away, and the main parachute of 1,200 square meters was deployed!
At this time, the pilots of other helicopters also found the target, and they all started flying towards the target!
The bell-shaped return capsule has been burnt to black during the return process. When it enters the atmosphere, for a period of time, its appearance is burning, like a meteor. It reduces by burning. The internal temperature sounds very mysterious, but that's how it is done.
Now, the return cabin slowly landed and landed. When it was a few meters away from the ground, the parachute was loosened, the brake rocket below began to ignite, and the return cabin landed steadily on the ground. This scene has been captured by the helicopter. The cameraman on the site recorded it.
"They did a great job, the error is less than twelve kilometers." Old Ren looked at the Beidou positioning system on the helicopter and said with a sigh.
Relying on the parachute to recover, the error is only a dozen kilometers, which is definitely a miracle. Now, the helicopter has landed next to it, and a crowd of people have gone down there. If it is a manned launch, now, They have begun to help astronauts get out of the cabin. As for now, although there are no astronauts, their standards are still the same, and some people even carry a stretcher to go there.
"Oh, no!" someone shouted. At this time, the wind hummed fiercely, and the parachute's parachute rope did not fall off normally, which caused the return cabin to move. As a result, the return cabin that stood steadily overturned!
It would be uncomfortable if there were people in it. It seems that this is something that needs improvement!
