1405: C1405 Long March 5

C1405 Long March 5

From the Weapon Graveyard, he found a Black Duck and Electronic Reconnaissance Aircraft. After exchanging them, he smashed it into pieces and handed it over to the people of Bear Country. Then, he opened the container and took it away.

From the Weapon Data Cemetery, he found the GPS satellite's Design and gave it to Elder Sun and the others. He asked them to imitate the real thing and the information. This way, the progress would be even faster. Qin Guan's goal was to set up the network of the Y Country's GPS system. He needed to set up his own Big Dipper System as well. At least, he needed to cover the entire Han Country. He wanted to expand it to the whole world.

If the GPS was the first to expand to the world, then their own Big Dipper System would be the first. It would not be easy to promote it. This was the situation in the future. They relied on the support of the country to promote it. For example, all trucks had to be installed with Big Dipper System and so on.

Only when the usage was high and the research and development cost was lowered would the cost be lower and lower. Otherwise, the project would end up in a dead cycle, and the final project would die.

"The Supreme Commander has agreed to the space project." Major Yang, who was next to Qin Guan, said to Qin Guan. At this time, the two of them were walking on the road of the Sixth Academy of Mechanical Industry.

Before they set off, this was the last thing Qin Guan wanted to do.

"Regarding the navigation plan that you mentioned, the higher-ups think... Risk. In a controllable range, at the same time, the profit is also high. Especially the army, they were all fully supportive of this project and felt that it was very important. However, in your proposed manned aerospace project... Many people have reservations."

Qin Guan nodded. This project definitely had disputes within the country. The elders of the aviation realm would definitely welcome them. However... The experts who want the country to develop its economy as soon as possible think that this project will lead to a huge waste of money... Right now, the country could not afford to start a business.

"Finally, the Supreme Commander gave his approval, and that is to take a step at a time" Major Yang said.

If he took a step forward, it would be too big of a step. It would be much easier to walk in different directions.

Now, Major Yang had brought Qin Guan here mainly to settle this matter.

The Sixth Aerospace Institute was the research and development center for the liquid rocket engine in Han Country. It was the only specialized research institute in Han Country that focused on the main power system of the rocket, the orbits control system, and the propulsion system of the spaceplane. It was known as the "national team" of the aerospace liquid power system and the "home of Han aerospace power."

The headquarters of the research institute was located in Jingke, and now, the two of them had arrived at the branch in the capital.

When they said this, someone in front of them came to welcome them. "President Qin, welcome to our place for inspection. We look forward to your arrival."

"Elder Ren?" Qin Guan looked at the person in front of him. This person was not the person in charge here. He was the leader of a higher department in charge. During the meeting that day, he was also present, but he didn't say much. However, Qin Guan knew that... He was one of the four famous aerospace elders in Han Country, and he had a high position in the aerospace industry. Just below old Qian.

Elder Ren was born in 1915 and graduated from university in 1940. After that, he went to Y Country to further his studies. He received a master's degree in mechanical engineering and a PhD in engineering, although he wasn't an Aerospace Technology major. However, under the needs of the motherland, he transitioned into a major. He turned to the aerospace system and quickly became an expert in Aerospace Technology and liquid rocket engine technology.

In 1980, he was elected as a member of the Han Country Academy of Sciences Department of Science, which was later on as an academician.

Now, he was already over 60 years old, with a head full of white hair, but he was still working on the frontlines.

"Elder Ren, I'm very happy to see you. You are an elder of the Aerospace Science Department." Qin Guan said.

"The older generation will push the older generation." Elder Ren said, "Qin Guan, the progress of our aerospace industry depends on young people like you. I know everything about Sun. Now, they are full of energy."

"Yes, Elder Ren. I will do my best." Qin Guan said.

After greeting the experts behind them, they went to the meeting room. Elder Ren pulled Qin Guan and sat on the rostrum. An important meeting began just like that.

"If we want to make a large thrust rocket, we first need to make a large thrust engine. We don't have any shortcuts on aerospace engines. We have to take it one step at a time. " Elder Ren said, "Now, we are in the middle of a long expedition. The hydrogen oxygen engine on it... It is a big problem. "

Qin Guan knew about this history. The Long March 2 used highly polluting nitrogen dioxide and partial dihydrazine as its propellers. When he was researching Long Conquering Three, he planned to add another level to it. At this level, Elder Ren insisted on using the most suitable hydrogen oxygen engine.

In terms of efficiency, the hydrogen oxygen engine was the most efficient, but it was also very difficult. Han Country had experienced setbacks in their research and development. In 1978, the first test of the hydrogen oxygen engine was that 10 people were injured due to the illegal operation.

Failure caused the hydrogen oxygen engine to almost fall off its horse, but Elder Ren was the one who did it. Continuing the research and development, under his insistence, he had to use this kind of advanced engine. Later, he encountered failure. In 1984, Dongfang Red No. 2 only entered the small elliptical orbit. It did not reach the synchronous orbit because the second ignition of the hydrogen oxygen engine did not succeed.

It was very difficult to develop a new engine. Now, Qin Guan said that he wanted to create a hydraulic oil engine with a greater thrust. It was a huge step.

As an elder of the aerospace rocket engine, Elder Ren personally attended this important meeting.

Unlike other scientific research projects, aerospace engines were often different. There were no experiences or models that could be used as reference. They could only be tested again and again. To master complex fluid laws, this new type of engine... Before they came into contact with it, it was very easy to fail.

"Now, the most mature one is the Long March 2. Its first level is the Dafay6-2 engine. It belongs to the model with the greatest thrust. This engine is made from four liquid engines with a thrust of 75 tons. In other words, we only have 75 tons of thrust in our hands right now. " Elder Ren continued, "The space station you mentioned, President Qin, needs a 400-ton large engine. With our current level, it is very difficult for us to achieve it. So, ___ said, the space station that you mentioned needs a large engine with a thrust of 400 tons. We want to first carry out a simpler plan, which is to push the gas engine to 120 tons. And with this as the foundation, form our new launch rocket. Raise our current maximum land capacity of 6 tons to 20 tons."

After Elder Ren finished speaking, he smiled at Qin Guan." We might be laughed at by President Qin. Satellite is everywhere. Only units like us that really release satellites do not dare to release satellites. "1

Qin Guan shook his head. "No, Elder Ren, your plan is more suitable and safer. I agree with your idea. Is our Long March 5-5 going to be established?"
