Chaoshen Technology Trading Mall Chapter 669

However, when the aircraft skeleton of Tiangong Technology came out of the painting workshop and entered the final assembly workshop again, Wang Bin, who wanted to continue the final assembly of the aircraft in the workshop, had to come out of the workshop.

　　 After several days of assembly work, their second Tiangong-4 rocket has been assembled and has been erected on the launch pad.

　　 At the same time, their first deep space satellite of Tiangong Technology has also completed the research and development and assembly work, and has also been installed on the rocket, just waiting to be launched.

　　 Of course, according to the original plan, this rocket should have been launched a few days ago.

　　 However, due to the unsatisfactory weather conditions these days, the rocket has not been launched during this period of time.

　　 According to the weather forecast, today's weather will be very good, so after learning about the weather a few days ago, Tiangong Technology decided to launch the rocket this afternoon.

　　 Of course, before the launch of the rocket, Tiangong Technology had already reported the matter to the superior and had obtained the consent of the superior.

　　 Of course, with Wang Bin and their Tiangong Technology successfully manufacturing this satellite, it also means that Tiangong Technology has successfully mastered the satellite manufacturing technology, and it is also the manufacturing technology of deep space exploration communications and relay satellites.

　　Actually, in general, compared to rocket manufacturing technology, satellite manufacturing technology is relatively simpler. Of course, this is only compared to low-Earth orbit satellites that are technically less complicated and have a single function.

　　Because in an environment such as space, satellites must consider many factors, such as weightlessness, high radiation, high temperature, low temperature, impact of meteorite debris, and so on.

　　 It is precisely because of this that the material requirements for satellites are very high, and their Tiangong Technology has made good achievements in materials.

　　 As for this satellite designed and manufactured by Tiangong Technology, its technical difficulty is much greater, even if it is compared with rocket technology, it is not much.

First of all, it is natural that the weight of this satellite has reached more than ten tons, and the function of this satellite is also very many. At the same time, the trajectory of the operation is outside the geosynchronous orbit. The most important thing is that this satellite also adopts a new type of satellite. Means of communication.

　　 As the launch time approached, Wang Bin came to the rocket launch site console of Tiangong Technology. At the same time, Wang Bin was still a little excited.

After all, the satellite launched this time is the first time their Tiangong Technology has launched a spacecraft developed and manufactured by itself. Although their Tiangong Technology has the ability to launch a variety of rockets before, they basically all launched. It is an official satellite, and has never launched its own satellite.

Of course, this is also related to the fact that Tiangong Technology did not have this need, but it is different now. Due to the official proposal of Tiangong Technology's deep-space star chain plan, it is foreseeable that most of the rockets they will launch in the future will be Will carry their own satellites of Tiangong Technology,

It is reasonable to say that since Tiangong Technology is developing satellites for the first time, it is necessary to proceed step by step and first develop small low-orbit satellites with a single function and less complex technology. However, Tiangong Technology directly develops outside the geosynchronous orbit. The high-orbit satellites, and the satellites with complex functions.

At the Tiangong Technology rocket launch site, a slender rocket was standing there at this time, but Wang Bin discovered that this Tiangong-4 rocket seemed a little different from the first Tiangong-4 rocket before. That is the fairing of this rocket. It is much larger than the one launched before, and its diameter is even larger than the core stage of the rocket. At the same time, the length of this fairing is much longer. It is more than ten meters long, and the length and diameter of the fairing of the rocket launched before are not as large as it is now.

　　 It is precisely because of this that Wang Bin feels that this rocket is a little different from the previous ones. After all, in the current situation, this rocket looks much larger, and at the same time it feels longer.

However, there is no way. Although the satellite developed by Wang Bin and his team is only about ten tons in weight this time, it is the first time that Tiangong has developed a satellite, and it is still a satellite with complex functions. So on the technical level , It's still a bit rusty. In addition, because the trajectory of this satellite is outside the synchronous orbit, it is necessary to consider many factors compared with the low-orbit satellite. At the same time, add Wang Bin's view of this satellite. The first requirement is also very long, and it must have the ability to operate for more than 50 years.

　　 Therefore, the satellites developed by Tiangong Science and Technology are only so large in size and heavy in tonnage.

　　 Of course, because the satellite launched this time was developed by Tiangong Technology itself, and the orbit is outside the synchronous orbit. At the same time, this satellite is also the first satellite of the Deep Space Starlink project.

Therefore, the launch of this satellite this time has naturally received great attention from the government. The entire control center, as well as various satellite experts and aerospace workers who have heard the news, are crowded. At the same time, these experts They were all discussing things in low voices, including Mr. Qin, the head of the aerospace department.

Wang Bin quietly looked at the rocket in the middle of the launch pad, and beside the rocket, there were a lot of people busy at this time. Wang Bin knew that this was the technical staff of their Tiangong technology rocket who was working on this rocket. The final check.

At the same time, at this time, there was no aircraft flying over the rocket launch. Even if it is some civilian drones, it is obvious that the sky near the rocket launch site of Tiangong Technology has been It's banned.

　　 "Mr. Wang! The rocket is in good condition and the fuel has been added. It can be launched at any time. Is the launch mission performed as originally planned?" Sun Lao came over and said to Wang Bin.

　　 "According to the original launch plan." Wang Bin turned his gaze to the person in charge of the launch who was asking him, Sun Lao said.

　　 Just after Wang Bin finished speaking, the staff at the launch site also began to evacuate one after another, and at the same time the countdown to the launch of the rocket began.

"30.29.28...3.2.1! Ignite! Launch!" As the rocket launch countdown ended, the controller on the launch pad on the side gently pressed the red rocket firing button and stood upright. The Tiangong-4 rocket in the launch site immediately spewed countless hot flames from its tail, and the Tiangong-4 rocket began to slowly leave the ground.

At the same time, when the rocket is ignited, countless water jets are also sprayed from the rocket launch pad, and it is quickly vaporized after contact with the flame ejected by the rocket to reduce the impact of the flame ejected by the rocket on the launch pad. At the same time, the water vapor can also effectively suppress the huge sound produced by the rocket when it is launched.

At this time, the Tiangong-4 rocket, as the height rises, the color of the flame ejected by the rocket has also changed, from the original orange-red to a completely transparent white soon, as you can imagine, At this time, how high the temperature of the flame sprayed by the rocket is, what harsh operating environment the rocket engine needs to withstand.
