The entire convoy followed the slope indicated by the arrow and turned onto the asphalt road. The flat road surface and the specifications of six lanes were no worse than the national highway. The road was easy to drive on, and the convoy's originally slow speed immediately increased to more than 80 kilometers per hour. As the convoy continued to move forward, the green on both sides of the road continued to decrease. After half an hour, there was no trace of green grassland in the field of vision, but it was replaced by a black Gobi desert that stretched as far as the eye could see.

"There was a fine grassland ahead, but why did it turn into a black Gobi Desert here? It's bare and covered with gravel. Everywhere you look is black, without a single bit of green. It makes people feel desperate at first sight." Du Qingqing is an emotional girl and doesn't like the surrounding black Gobi Desert very much.

"This area was originally a grassland. It is said that it was the territory of a noble herdsman named Suhe. He had many wives and concubines and was extremely extravagant. He treated his herdsmen very harshly. Insults and beatings were common. He often bullied men and women. There were also many herdsmen who were abused to death by him. Ulana was born in a local herdsman family. She was very beautiful since she was a child and was a famous beauty in the neighborhood. She had a childhood sweetheart boyfriend, Amur. They were neighbors and grew up together. They had a very deep relationship. On the eve of their wedding, the evil herdsman Suhe showed up and led his private soldiers to kidnap Ulana. Amur was so angry that he went to the place where Suhe lived to rescue Ulana, but his legs were broken by several big men who were guarding the door. That night, Suhe broke into the place where Ulana was imprisoned and wanted to take her by force. Ulana couldn't bear the humiliation and chose to hit the wall to commit suicide. Upon hearing the bad news, Amur, who was in bed recovering from his injuries, cried for three days and three nights, and then dragged his injured leg to find someone to use his connections to get Ulana's body back and buried it in He went to the place where they often grazed together and vowed to avenge Ulana. Since then, Amur has completely disappeared from people's sight. Until ten years later, a lame monk came to Ulana's grave with a Zen stick and chanted scriptures and prayed. Until midnight, the lame monk came alone to the luxurious yurt where Suhe herdsman was stationed, raised the Zen stick with one hand, chanted a spell, and attracted the sky fire. The boundless flames blocked the area within a radius of 100 miles and burned for seven days and seven nights. The sky fire not only The whole family of Suhe the herdsman and his lackeys were burned to death, and the nearby grasslands were all burned into a scorched earth, becoming the Black Stone Beach today. Of course, these are just local folk tales and should not be taken seriously. The cause of this black Gobi Desert is probably that the surface soil layer is too thin, overgrazing has destroyed the roots of the grass, destroyed the surface vegetation, and a few strong winds have blown it down, and it has become what it is now. "While driving, Qiao Ruida told his girlfriend the legend he heard from the local guide.

"What a tragic love story! Maybe it's true. Otherwise, how do you explain the black stones and black soil that can be seen everywhere?" Du Qingqing actually believed in such a legend that was full of loopholes and even found a seemingly reasonable argument for it. No one else can do that.

"The soil and rocks here are black because they contain iron and manganese. These two elements react chemically with water to produce iron oxide and manganese oxide that cover the surface of the soil and stones, making them appear black. It has nothing to do with burning from the sky or anything like that." In order to correct his girlfriend's wrong idea, Qiao Ruida gave her some popular science information about the causes of the Black Gobi Desert.

During the time when the two were talking, the convoy had already arrived deep in the Black Rock Beach. From a distance, they could see the open space ahead, with tower cranes standing in rows and machinery roaring. There were a large number of construction machinery and construction workers, who were busy and tense. Many buildings had just laid their foundations, and workers were currently tying steel cages and pouring concrete. The transport trucks and muck trucks encountered on the road, all transported supplies and building materials, and all were delivered here. The first phase of the Ruida Aerospace City alone covers an area of ​​500 acres. The main buildings include two satellite launch towers, a rocket control center, a rocket recovery site, two high-standard runways, and a number of supporting workshops and factories. To complete these construction projects, a huge amount of construction materials are needed, and these transport vehicles must continue to transport them.

Seeing their company's convoy arrive, several staff members who were sent ahead to meet them all came forward. Qiao Ruida parked his car in a vacant lot, and the other drivers in the convoy followed suit and parked their cars nearby. Only the two semi-trailer trucks transporting the first stage of the Suzaku rocket drove onto the rocket recovery site that had just been built.

Qiao Ruida, Du Qingqing and others had just gotten off the car when Wu Ziqiang, who was leading the way, came up with several of his men and said, "Boss Qiao, Boss Cao, Manager Du, you've worked hard along the way."

"It's okay. The first half was smooth, but the last section of unpaved road is too difficult to drive on. It's so bumpy that it makes people question their lives. How is the preparation work on your side? Can it meet the needs of tomorrow's test?" Qiao Ruida casually responded with a few words, and then asked about the situation here.

"The preparations are almost done. The rocket recovery site has been leveled and covered with high-grade cement. It can be used for rocket launch and recovery without any problems. The methane and liquid oxygen storage stations have also been completed and the equipment has been installed. Only liquid oxygen and methane have not been transported here. I have consulted the supplier and they said that liquefied methane cannot be excessively bumpy during transportation to avoid danger. Therefore, the last unpaved section leading to Ruida Aerospace City cannot be transported here. We can only wait for our construction team to complete the asphalt road before liquid oxygen and methane can be transported here." Wu Ziqiang gave a detailed report on the current situation to Qiao Ruida. To sum it up in one sentence, everything is ready except for the east wind.

The fuels generally used in traditional liquid rockets are liquid oxygen-kerosene, liquid hydrogen-liquid oxygen, or highly toxic hydrazine fuel and liquid oxygen. The Suzaku launch vehicle innovatively uses liquid methane and liquid oxygen as fuel. Compared with the previous three, methane has many advantages such as higher specific impulse, basically no carbon deposits, good thermal conductivity, easy multiple starts and variable thrust adjustment. As early as the beginning of the construction of Ruida Aerospace City, the suppliers of methane and liquid oxygen were contacted, and the two parties signed a long-term supply contract. Unexpectedly, the final problem still appeared in the supply of fuel.

"Then with the current construction progress, when can the road be built to the national highway?" Cao Yifei asked irritably. So many people and so many cars came to the Aerospace City from afar just to conduct the takeoff and recovery test of the first stage of the Suzaku rocket. As a result, the road is blocked now, the fuel cannot be transported, and the test cannot be carried out. It is normal to be a little irritated. If Qiao Ruida hadn't been here to hold the fort, Cao Yifei would probably have scolded Wu Ziqiang severely.

"This morning, I consulted Qian Gong, who is in charge of the road construction at China Construction Fifth Bureau. He said that the road will be completed within two days, and methane and liquid oxygen will be delivered the day after tomorrow." Wu Ziqiang also noticed that Cao Yifei did not seem to be in a very good mood, and he couldn't help but shrink his neck and spoke carefully.

"It's just two days, we can wait. Let's unload the cargo and check the system before it gets dark. We don't know if the rocket has been affected by the bumpy ride. If there is a problem, it will not be a two-day delay." Qiao Ruida patted Cao Yifei on the shoulder, signaling him to be patient. "Okay, Mr. Qiao, the large crane is ready and can be used to lift the rocket at any time."

Most launch vehicles are of astonishing height, with 49.5 to 20 meters being the conventional height, and to meters being not uncommon. For some heavy rockets, it is also common to exceed meters. Like the Suzaku rocket, the completed body is only meters high, which is already considered a dwarf among launch vehicles. Because the launch vehicle is so high, it is generally produced horizontally, transported horizontally, and finally hoisted and assembled at the launch site. Considering that cranes will be frequently used in the aerospace city in the future, two large cranes were ordered from XCMG Group as early as the beginning of the development of the Suzaku rocket for rocket hoisting operations. Now two months have passed, and XCMG Group has delivered one of the cranes, which just came in handy this time. This rocket test only involves the first-stage module, and there is no need to assemble the entire rocket, but the height of the first-stage rocket is also more than meters, which is not something that can be hoisted by an ordinary vehicle-mounted crane. Only this kind of specially customized big guy can easily cope with the hoisting operation of the launch vehicle.

Under the guidance of Wu Ziqiang, an oversized truck-mounted crane drove to the side of two semi-trailer trucks. Under the operation of the driver, the crane lowered as many as eight sturdy hydraulic support legs, and only supported two sections of the boom to reach a height of 30 meters, easily lifting the first-stage rocket from the semi-trailer truck and placing it vertically on the designated position of the rocket recovery platform. Candice led a group of engineers and quickly came up to lower the four support legs folded on the outside of the rocket body to support the rocket body. The steel wire rope used for lifting was then removed, and the first-stage rocket, relying entirely on its own support legs, stood on the recovery platform. After the first Suzaku rocket first-stage module was hoisted, everyone immediately went to hoist the second first-stage module. With the previous experience, the second rocket first-stage module completed the hoisting operation in just ten minutes and stood on the other end of the rocket recovery platform.

"This rocket is more than 20 meters high, but its four supporting legs are so short. It doesn't look very stable. Aren't you afraid that a strong wind will blow them down?" Du Qingqing walked to the rocket, looked up at the top of the rocket, and asked worriedly.

"Don't be fooled by the short size of these four supporting legs. They are actually made of special alloys and are very strong. The supporting angles have also been precisely calculated, which is enough to ensure the stability of the first-stage rocket. As long as there is no strong wind above level 10, there is no need to worry about them falling down." The entire design plan of the Suzaku rocket was come up with by Qiao Ruida. He was well aware of the technical details and gave his girlfriend a popular science explanation.

Wu Ziqiang opened an iron manhole cover next to the rocket, pulled out several cables and pipes from underneath, and connected them to the corresponding slots at the tail of the rocket. These cables and pipes can be used to power the rocket, transmit data, and refuel. It is not an exaggeration to say that they are the life arteries of the rocket. There were also staff members doing the same work next to another rocket.

"Boss Qiao, Boss Cao, engineer, the pipeline connection is complete, let's move to the temporary control center. There are equipment there to complete the inspection of the first stage of the two rockets." After doing this, Wu Ziqiang led Qiao Ruida, Cao Yifei and others to the rocket recovery site. There were several temporary houses built with colored steel plates, which were the so-called "control center."

The temporary control center only occupies an area of ​​about 100 square meters. It is filled with tables, chairs, computers, servers, and various cables crisscrossing and pulling everywhere. These equipment were brought by Wu Ziqiang and other pioneers in preparation for subsequent rocket tests. Wu Ziqiang and his pioneers were able to complete the installation of liquid oxygen and methane storage equipment and the construction of the temporary control center in just one week. They really worked hard enough.

At this time, more than a dozen people were busy sitting in front of computers. The information data from many sensors on the rocket was transmitted to the server here through cables, and then read, decoded, and classified by the program, and finally presented on the computer screen. There were many tables and chairs in this temporary control center, but only more than 20 computers were placed. Qiao Ruida and his group had 65 people, and these computers were obviously not enough. Fortunately, Cao Yifei had been prepared for this. He called on his employees to move a large number of desktop computers, laptops, and other miscellaneous equipment from the three tool trucks, and sent them all to the temporary control center for assembly.

After half an hour of hard work, all the computers were installed. At this time, in this small board room of less than 100 square meters, there are no less than 100 computers and various equipment installed. You can imagine how crowded it is. Various network cables, power cables, and data cables are crisscrossed in the room, just like entering a cave. After preparing the tools, the next step is to conduct a comprehensive inspection of the first stage of the two rockets. Every sensor parameter and every component must be checked. After all the tests are correct, a simulation of the entire process of ignition, launch, hovering, and recovery must be carried out to ensure that the program is smooth and correct, and all active parts can respond in time. It took two hours to complete all the work.

"Mr. Qiao, Mr. Cao, there are no problems with the first-stage modules of the two rockets. As long as we add fuel, we can take off and conduct tests at any time." After summarizing the test results, Candice breathed a sigh of relief and made a final report to Qiao Ruida and Cao Yifei.

"That's good. It's getting late. Let's go to the temporary cafeteria to eat." The test results were all normal. Qiao Ruida was relieved and invited everyone to go to the cafeteria to eat. (End of this chapter)
