Ultra-Dimensional Technology Era

"Report, Long [-]-D has broken through the Karman line."

"Report, core-level separation was successful."

The control team in charge of the core level immediately took action.

After the separation, the second stage of the core continued to push the Chang 1500-D towards the [-]-kilometer low-earth orbit.

The main engine of the core stage has been turned off, and the auxiliary engine is started to quickly correct the flight direction.

In 15 minutes, the head of the rocket body of the core stage was slightly down, and the main engine at the tail was slightly up.

"The core level enters 3 meters."

"Deploy auxiliary flight wings."

The foldable hollow wings made of high-strength materials unfolded immediately, and the core stage suddenly became an airplane.

As for the impact of the head not conforming to aerodynamics, it has nothing to do with the core level. After all, the design concept of the core level is for the convenience of recycling, not as a high-speed aircraft.

Under the action of the auxiliary engine, the core stage becomes a large UAV, and under the guidance of Beidou navigation, it flies to Wenchang Space Launch Center.

At this time on the observation area.

"Oh my God!"

"Sikuyi!"

"space shuttle!"

Unfold the core stage of the landing wheel, and slowly land and taxi on the runway.

David hastily manipulated the camera, closely following the figure of Xinyi.

"It turned out to be a space shuttle." Karina stared at the core on the runway with wide eyes.

After the first-level core stopped, the staff who had already been prepared drove the first-level core into the maintenance workshop with a tractor.

at the same time.

Near the 300-kilometer low-Earth orbit, the second-level core has also successfully separated, and is orbiting a 300-kilometer orbit, gradually approaching the blue star's atmosphere.

However, it will take some time for the second core to return to the launch center, and it is estimated to take about 50 hours, mainly because it takes a lot of time for the blue star to orbit.

2 Chapter [-] Core Secondary Recycling

Inside the maintenance workshop of Wenchang Aerospace Center.

Li Guoqing was already looking at the first-level Changwu-D core that had just been recovered in front of him.

Engineers and maintenance personnel quickly use various equipment to detect the condition of the core level, mainly to repair the shell structure, electronic components, engine combustion chamber, nozzle, fuel delivery pump and pipeline, etc.

It focuses on the fuel transfer pump, a series of sensors and control valves inside the fuel storage tank.

Because of the use of very strong new materials for the combustion chambers and nozzles of the first-stage engine of the Changwu-D core, there is at least 30% to 40% performance redundancy for the high-temperature and high-pressure endurance.

In space launch vehicles, the most problematic components are often electronic components and fuel delivery pumps.

This is a conclusion that has been analyzed with big data. Whether it is the internal statistics of the Huaguo Space Administration or the data released by NASA or the Lucia Space Agency, among space launch vehicle or space shuttle accidents, more than 60 accidents caused by electronic component failures %.

"Mr. Li, the three sets of electronic systems have been tested, and there is no problem for the time being." An engineer reported.

Li Guoqing, who did not take it lightly, ordered again: "After the other parts are inspected, the key components such as electronic components will be inspected again."

"no problem."

When Li Guoqing was busy overhauling the first level core.

In the command hall of Wenchang Aerospace Center, Chen Yao also watched the second-level core orbiting the blue star and gradually descending into the atmosphere.

However, the staff in the command hall focused on the third-level core. Even if the recovery of the second-level core failed, the loss would not be large; but the third-level core and the four satellites carried on it were important.

After all, the cost of a single satellite is 8 million, and four satellites are 32 billion. If something goes wrong, the gain will not be worth the loss.

……

Reporters and aerospace enthusiasts in the observation area are talking about it.

Karina and David did not expect that the recovery method of the Long [-]-D launch vehicle is like this.

"Isn't this the space shuttle?" David complained.

Karina repeatedly watched the landing of the core stage just now. The more she looked, the more she looked like a space shuttle. However, unlike the space shuttles of the United States, the Long [-]-D does not pay attention to appearance, which looks a bit rusty and ugly.

But as long as it is successfully recycled, who cares if it is ugly, it is still beautiful.

David next door is watching the live broadcast on his laptop. As a foreign media, he is not qualified to enter the space center for interviews.

As for the media with internal interview qualifications, there are only three media outlets: Xinhua News Agency, National News, and Zhenzhen Xuebao. You can watch the live content of National News and Zhenzhen Xuebao on the Internet.

In the live broadcast, the national news reporter is interviewing Chen Yao.

"Designer Chen, how is the first-level recycling of Changwu-D's core this time?"

Chen Yao replied with a smile: "It is currently undergoing maintenance. According to the preliminary feedback, the first-level core is in line with expectations."

The reporter continued to ask: "I heard that the second-level core of Changwu-D is also a recycling design, is it the same as the first-level core?"

Chen Yao nodded and replied: "Except for the two stages of orbiting and re-entering the atmosphere, the other situations are similar."

"Then when is the second core expected to return to the ground?"

"Probably around 50 hours."

……

There was even a second-level recovery of the core. For the first time, David put away his contempt.

Karina on the side is also feeling heavy. If Chang 37.2-D achieves first-level and second-level core recovery, plus the [-]-ton payload, Huaguo Aerospace will be on par with them.

Now NASA's own production and R&D capabilities have been suppressed, and it has been reduced to the point of purchasing Lucia rocket engines. Only the private company's space exploration company is capable.

The remaining companies such as Google, General Motors, and Locke Martin are now developing so-so in Locke Martin.

Because of the semiconductor and Internet wars in the past few years, Google has been somewhat overwhelmed with the aerospace field; and GM has also lost money for 18 consecutive months due to the impact of the electric vehicle market. How can it have time and funds to invest in the aerospace field.

Under the circumstances of ebb and flow, it is already foreseeable that Hua Guo will catch up.

Karina picked up the binoculars, observed for a while the launch tower and the fully sealed maintenance workshop on the side, and then put away the binoculars.
