The low-Earth orbit carrying capacity of the Long March 2 rocket is only less than ten tons, and it will not be able to meet the exploration of space for a long time in the future, especially if an orbital space station is to be established, it will be hundreds of tons of man-made Celestial bodies, it is impossible to rely on Long March II.

Therefore, a new generation of high-thrust launch vehicle is already in Qin Guan’s plan. On the one hand, the diameter of the rocket is expanded from 3.35 meters to 5 meters. On the other hand, it is to use the latest engines to replace the previous backward engines. Eliminate and use new pollution-free engines.

These studies are progressing smoothly. The engine has been tested many times and proved that the overall operation is good. Then, it is time for the entire rocket to fly.

The cost of launching a rocket once is quite huge. At this time, a separate launch experiment is undoubtedly wasteful. However, even if it is carrying its own satellites, there are risks. Needless to say, carrying foreign commercial satellites. Suddenly, It's certainly better to have a customer in need.

"Yes, President Qin, we will carefully prepare for the launch, and we must make this launch a complete success!" said Ren Lao, the project leader.

President Qin came here to set the tone for everyone. We have to take over this launch mission. After receiving it, it will be beneficial to us.

To put it simply, you will no longer have to wait for higher-level approval for future scientific research projects. After this launch mission, we will have money. In the past two years, we will spend whatever we want.

Regardless of white or black cats, catching mice is a good cat. No matter what you have before, you have launched satellites and made money! This is Qin Guan's opinion.

The Eagle State was really anxious. After receiving the agreement from the Han State, within a few days, a special transport plane flew to the Yedao launch base in Han State.

And Qin Guan came to the space base of Yedao enthusiastically.

After several years of construction, Yedao’s space base has completed all supporting projects, and the launch pad prepared specifically for the Long March 5 rocket has also been activated.

"Our rockets are developed in a modular manner. According to the needs of launching, different modules can be equipped to achieve different carrying capabilities." Ren Lao introduced to Qin Guan: "Now, our mission requirements are two stars with one stone. We will launch a weather satellite and a resource exploration satellite to Eagle Country, with a total weight of ten tons, so we can use our most basic composition."

The rocket has already been assembled in the assembly plant next to it. As long as it passes the ground rails, it can be transferred to the launch pad. At this time, Qin Guan is in the assembly plant, looking at his own rocket this time. .

In fact, the Long March 2 can also launch a satellite of about ten tons. However, the technology of the Long March 2 is backward and requires two stages to get into orbit. Now, for this launch, only a single stage is enough. The rocket The core level is five meters, it looks very thick, only one level, the total length is more than 40 meters, looks mighty and magnificent, at the same time, four 2.25 meters diameter boosters are bundled outside to complete the launch. The task is simpler.

The more stages of the rocket, the more complicated the structure, and the more accidents during launch. With the continuous improvement of rocket thrust, the number of stages of the rocket is decreasing. Now, the launch of the Long March 5, The simplest form is also adopted. This is to reduce the risk of launch as much as possible. Although the Eagles have taken a lot of insurance, if the launch fails, it will still have an adverse impact on the aerospace industry of Han. May scare away potential customers.

The central core stage is very thick. The four outside boosters are tied to the side. The tip of the booster is tilted to the side of the core stage, forming a closed and enclosed structure. Looking at this modern rocket, Qin Guan is also very satisfied: "Our spacecraft is about to make a manned flight. After the spacecraft’s manned spaceflight, the space station will be launched. At that time, our Long March 5 will be able to launch our space station. !"

The maximum low-Earth orbit is 25 tons, and four launches can assemble a 100-ton space station, which is quite good.

"Yes, we are also looking forward to the launch of the space station project." Ren Lao said.

"Wait, you can't go in!" At this moment, a voice came from outside. Hearing this voice, Qin Guan's face suddenly became serious.

The Eagles are here, and they are still so rude. Don't they know how much effort has been made by their foreign affairs department to undertake the launch mission for them?

"Our Husseus company’s satellite contains a lot of secrets. We have to watch the satellite mounted on the rocket. Otherwise, if you disassemble the satellite to study ours, then our loss will be great!" A cold voice Said.

"If you have such suspicions, then you can now carry your satellites and leave!" At this time, Qin Guan has already strode out, outside, watching several Eagle Country technicians Next to a special transport vehicle, a behemoth several meters high wrapped in oilcloth on this vehicle was a satellite specially transported from Eagle Country.

Royce, the engineer of the Seuss Company, was very angry at this time. They built this satellite, but it was not up to the launch mission and could only be sent to Han for launch. As a result, the Han people did not allow it. They entered, and Royce was immediately furious.

He was suffocated at first, but now, Qin Guan's words made him startled again. He finally came over, and he wanted to get it back again? Do you know how difficult it is to transport each time? A large overload may cause some parts of the satellite to malfunction. We came all the way and then drove us away?

"The launch contract for you has been signed. We have written clearly on it. We cannot allow you to contact our rockets, because our rockets contain a lot of our technical secrets. We did this for confidentiality. Since you don’t If you plan to do it in accordance with the contract, then take the satellite back. We will not refund the cost you have already paid." Qin Guan said with confidence.

Do you think it was the previous era? Think that your technology in the aerospace field is the most advanced, so you can be arrogant? Especially now, with a high-spirited idea, to crush Han's spaceflight? Stop dreaming, if you want to launch, follow the agreement, if you don't, then get out!
