Chapter 333 Launching Satellites
In a secret base in the Gobi Desert in the northwest, a group of rocket experts are carrying out the final debugging work. Many of these experts have returned from studying abroad, and they have brought the latest rocket technology and concepts.
Standing in front of the rocket launch pad, looking up at the huge metal giant, although he was familiar with satellite technology, he still couldn't help but feel a little in awe of this behemoth.
"Comrade Li," a gray-haired old expert came over with a gratified smile on his face, "thanks to the efforts of your satellite team, our rocket has a clear goal. Now, let me introduce our 'Long March' rocket to you."
The old expert took Li Yang into the control room and pointed to a huge blueprint on the wall and said, "This is our Long March 28 carrier rocket. It has a three-stage structure, a total length of 81 meters, and a takeoff weight of about tons."
Li Yang studied the blueprints carefully and couldn't help but exclaimed: "What a remarkable project! But I heard that the rocket encountered many difficulties during its development?"
The old expert smiled bitterly and nodded: "Indeed. One of the biggest challenges is the development of the engine. As you know, rocket engines need to generate huge thrust in a very short time, which places extremely high demands on materials and processes."
He pointed to a section on the drawing and continued, "This turbo pump in particular needs to work at extremely high temperatures and pressures, pumping tons of fuel into the combustion chamber every minute. Initially, we kept encountering problems with turbine blades breaking."
Li Yang nodded thoughtfully: "I see. This is indeed a difficult problem. How did you solve it?"
A hint of pride flashed in the old expert's eyes: "We have developed a new alloy material that can not only withstand extremely high temperatures, but also has excellent fatigue strength. At the same time, we have also optimized the design of the blades, using complex three-dimensional twisted shapes, which greatly improves efficiency and stability."
At this moment, a young engineer came running over with an excited expression on his face: "Report! We have just completed the last ground ignition test, and all parameters have reached the expected targets!"
The entire control room suddenly erupted in cheers. Li Yang and the old expert smiled at each other. They both knew that this meant the rocket was fully ready and could be launched at any time.
However, the real challenge has just begun. How to safely send the satellite into the predetermined orbit is an extremely complex process that requires close cooperation between the rocket and satellite teams.
……
The next morning, Li Yang led the satellite team to the launch site. In a huge clean room, they carefully loaded the satellite into the rocket's fairing.
"Remember," Li Yang told his team, "the satellite will be subjected to huge vibrations and accelerations during launch. We must ensure that every connection point is strong and reliable, and every component is correctly positioned."
The engineers held their breath and carried out the final inspection meticulously. Every screw was carefully checked and every electronic component was tested repeatedly. It was a long and tense process, but no one complained because they all knew that any tiny negligence could lead to the failure of the entire mission.
Just then, Li Yang noticed a detail. "Wait a minute," he suddenly said, pointing to a corner of the satellite, "the connector of this solar panel seems to be wrong."
Everyone held their breath. Li Yang carefully checked and found that the connector was slightly loose. If it was not handled in time, it would likely fall off during launch, causing the satellite to lose energy.
"That's great, Mr. Li!" A young engineer breathed a sigh of relief. "If you hadn't discovered it in time, the consequences would have been disastrous."
Li Yang shook his head, his expression serious: "This is not anyone's credit, but the attitude we must have. In aerospace engineering, any slight negligence may lead to catastrophic consequences. We must always be vigilant and pay attention to every detail."
After this incident, the team completed the remaining assembly work more carefully. Finally, when everything was ready, the satellite was carefully sent to the launch pad.
Standing at the launch pad, Li Yang looked up at the rocket that soared into the sky, his heart filled with mixed emotions. Months of hard work and countless sleepless nights were all condensed into this behemoth. At this moment, he couldn't help but think of the night when he accidentally got the "golden finger" and the mission he shouldered.
"Engineer Li," a young engineer said quietly, interrupting Li Yang's thoughts, "we have one last problem to solve."
Li Yang came back to his senses and listened carefully to the engineer's report.
"We found in our final simulation," the engineer continued, "that the satellite may face a serious thermal control problem after entering orbit. Due to the small size of our satellite, the heat cannot be dissipated fast enough, which may cause some key components to overheat."
Li Yang frowned. This is indeed a tricky problem. In the space environment, heat control has always been a huge challenge. Too high a temperature may cause electronic components to fail, while too low a temperature may cause mechanical parts to lose their function.
"I see," Li Yang said after a moment's thought, "We need a more efficient thermal control system."
He quickly drew a new design on paper: "We can add a special coating to the outer shell of the satellite. This coating will reflect most of the heat in the sun and quickly dissipate the heat in the shadow. At the same time, we can also add some phase change materials inside, which can absorb heat when the temperature rises and release heat when the temperature drops, playing a buffering role."
The engineers looked at this innovative design in amazement and nodded in approval. However, time was running out, and how to complete this change before launch became a new challenge.
"Don't worry," Li Yang comforted, "We can split into two groups. One group will be responsible for preparing the coating materials, and the other group will be responsible for installing the phase change material. As long as we work together, we will be able to complete the changes before launch."
In this way, in the last 48 hours before the launch, the entire team once again devoted themselves to intense work. They raced against time and worked almost non-stop. Finally, 6 hours before the launch, all the changes were completed.
After the last round of comprehensive inspections, the satellite and rocket were finally fully ready. Li Yang stood in the control room, looking at the big screen with the countdown, and his heartbeat accelerated involuntarily.
"10, 9, 8..." As the countdown progressed, the atmosphere in the entire launch center became increasingly tense.
"7, 6, 5..." Li Yang's palms began to sweat. He knew that every second that followed could determine the success or failure of the entire mission.
"4, 3, 2..." Everyone held their breath and stared at the screen intently.
"1. Ignite!"
With a command, a huge flame spurted out from the bottom of the rocket, illuminating the entire launch pad. Amid a deafening roar, the giant slowly left the launch pad and rushed towards the blue sky.
"First stage separated normally!"
"Second stage ignition successful!"
"Level 3 is working fine!"
As good news came one after another, the atmosphere in the control room became more and more heated. When the last piece of news came, the whole room burst into warm cheers.
"The satellite successfully entered the planned orbit!"
As the satellite successfully entered the predetermined orbit, warm cheers broke out in the command room.
Li Yang took a deep breath, wiped the sweat from his forehead, and a relieved smile appeared on his face.
However, he knew that the real challenge had just begun.
Just then, the door of the command room was pushed open and a group of leaders in Zhongshan suits walked in.
Li Yang immediately stood up straight and saluted them.
"Comrades, thank you for your hard work!" said a gray-haired old man with a smile. He is the Minister of the Ministry of Aerospace. Other leaders also nodded with expressions of approval on their faces.
Li Yang briefly introduced the launch process, then turned to the control console: "Now, we will start controlling the satellite to deploy its solar panels and test various functions."
His fingers tapped quickly on the keyboard, and the real-time status of the satellite was displayed on the big screen.
With a slight hum, the satellite began to slowly unfold its solar panels.
"The solar panel was deployed successfully!" a young engineer shouted excitedly, his eyes fixed on the screen, afraid of missing any details.
Li Yang nodded and continued: "Now, we are going to test the satellite's attitude control system."
He typed in a complex string of commands, and everyone held their breath, staring at the screen nervously.
The satellite began to rotate slowly, accurately adjusting its position.
"The attitude control system is working normally and the accuracy has reached the expected target!" another engineer reported, with undisguised excitement in his voice.
The leaders exchanged surprised glances, obviously shocked by the performance of the satellite. Most of them probably never thought that Yan Country's satellite technology could reach such a level.
Li Yang did not stop, he continued to operate the console: "Next, we will test the satellite's optical system."
A clear image of the earth's surface suddenly appeared on the big screen, and even the outlines of buildings on the ground could be clearly seen. There was a burst of exclamations in the room.
"This...is this taken from space?" a leader asked in disbelief, his eyes wide open, as if he couldn't believe what he saw.
Li Yang nodded with a little pride on his face: "Yes, this is the real-time picture taken by the high-resolution camera on our satellite. Our resolution can reach 0.5 meters, which is also the top level in the world today."
The leaders were talking to each other, obviously shocked by the news. Some of them even walked closer to the screen and carefully observed every detail.
Li Yang continued the test and activated the satellite's multispectral imaging system. The image on the screen suddenly turned into a colorful picture, with each color representing a different surface feature.
"What is this?" a young leader asked curiously.
