Chapter 1185: Prospects for manned spaceflight

Where there are people, there are rivers and lakes. The world is not peaceful, even in space. In the field of space, the bear country and the eagle country have always been in competition.
In the history of world aerospace development, Xiong Guo came out on top. They not only took the lead in launching the world's first man-made earth satellite "Mate One" on October 4, 1957, opening a new chapter for mankind to move into space, and successfully launched the world's first satellite on April 12, 1961. A manned spacecraft sent Gagarin, the first astronaut in human history, into space, ushering in a new era of human space flight.
In the fierce space hegemony at that time, the Eagle Nation seemed to be at a disadvantage. The Eagle Nation’s first artificial satellite was successfully launched on February 1, 1958 after the Bear Nation. Its first manned space flight was also in Gaga. Lin Shangtian did it a month later, and it has not been successful yet. They successfully carried out the first manned space flight on February 20, 1962. Astronaut John Green was sent into space and stayed for nearly 5 hours. Prior to this, the Xiong Guoren had flown into space for the second time on August 6, 1961, and the astronaut Titov stayed in space for more than 25 hours.
The competition in outer space cannot be left behind. After the founding of Han, senior officials and scientists also set their sights on the vast space. After hardships and setbacks, the "Dongfanghong-1" satellite was finally successfully launched on April 24, 1970, shocking the world.
What's the use of huge space activities?
First of all, it must be for military purposes. Other than that, those rockets are almost all from ballistic missiles. For example, Han's Long March 2 carrier rocket is actually from Dongfeng-5, and this is true in all countries.
At the same time, the first satellite launched was definitely not with regards to world peace. The first satellite began its military function.
For ground reconnaissance, military communications, guidance, etc., space will never be used for peaceful purposes.
And if someone goes into space, then they can give full play to their subjective initiative. This is also a decision made by a major country.
The spacecraft is the first step towards manned spaceflight.
The spacecraft is essentially the same as a returnable satellite. It is placed on the top of the launch vehicle and launched like a launching satellite. When returning, it is also a parachute landing method, but it is more comfortable.
However, this method can transport fewer people, up to three people at a time. The space is small and there is not much room for maneuver. Therefore, Xiong Guo and Ying Guo are both developing a new generation of spacecraft, the space shuttle.
A spacecraft is similar to a satellite, while a space shuttle is like a delta-wing aircraft. It launches upright and landed when returning. This greatly increases the reliability and can accommodate more people and objects. , For example, the Eagle Country’s space shuttle can accommodate seven members, and even ordinary people can go to space after training.
Moreover, in the design, the space shuttle can be reused, the purpose is to greatly reduce launch costs and improve efficiency.
Although Eagle Country’s space shuttle is very famous, Xiong Country actually has it. The Bear Country’s Blizzard is a special space shuttle, but it hasn’t completed all the test flight projects before Xiong Country is gone.
Nowadays, space shuttles are popular abroad. Therefore, the old space shuttles all hope to build space shuttles. Looking enviously, only Qin Guan knows that the stuff is tasteless!
Its biggest problem is that safety cannot be guaranteed. According to the plan, each space shuttle has to be reused at least one hundred times, but what about it? Discovery, which has the most lifted off, has only been launched 38 times, far from reaching the design target.
Due to the repeated use of the space shuttle, its technical difficulty is difficult, the system design is complex, and its components are more easily worn out. From take-off, ascent, orbiting, re-entry into the atmosphere and return to landing, it needs to withstand various extremely harsh environments.
After several launches, who knows where any tiny cracks will appear, even a small crack is fatal!
Among the five space shuttles of Eagle Country, two exploded and disintegrated during the mission, and 14 astronauts were killed.
Unlike single-use aircraft such as rockets and spacecraft, the rocket engine of the space shuttle needs to be used repeatedly, and the total working time during its life span is as long as several hours. This also brings safety hazards to its mission: The increase in tasks is bound to have more potential dangers.
In the end, the Eagles gave up. The Eagles retired the space shuttle and found that they did not have a manned spacecraft to use. Fortunately, there were many local tyrants among the Eagles, and they supported a private rocket company. Otherwise, the space capabilities of the Eagles would require Was castrated.
Qin Guan knows all these truths. Now that he has nothing to do, he can just have a mouthful. Moreover, as he passes through, the domestic aerospace program will definitely advance by a large margin!
"However, the spacecraft, we used to have a plan." Colonel Chen said, when he said this with regret.
Yes, in sync with foreign countries, there are also plans for manned spaceflight in China.
Before the successful launch of the "Dongfanghong-1", the preparatory work for manned spaceflight was already included in the research and development of Han scientists. For example, the sounding rocket once sent a little male dog named "Little Leopard" to an altitude of 70 kilometers above the ground in July 1966 and successfully returned. Immediately afterwards, the little named "Shanshan" was sent to the sky and was successfully recovered.
In the same year, the National Defense Science and Technology Commission held a demonstration meeting on manned spaceflight. After listening to the report, the then prime minister pointed out: While Han is accelerating the development of artificial satellites, the development of spacecraft should also be gradually carried out. In this way, the manned space program officially started.
With reference to various types of spacecraft, the researchers finally decided to design the first spacecraft in Han, based on the second-generation spacecraft "Gemini" of Eagle Country. The first spacecraft was named "Shuguang-1" and Qian Xuesen was the chief technical officer.
Unfortunately, this project ended without a problem. After all, the domestic technology is backward, and manned spaceflight will cost a lot of money. When the Apollo rocket was at its most brilliant, the investment in spaceflight each year accounted for 10% of the whole chicken's ass. One! Only the rich and powerful eagle country can afford it.
When Qin Guan heard Colonel Chen’s introduction of Dawn 1, his heart was an exciting spirit. In a few years, the newly appointed President of the Eagle Country will propose a Star Wars plan. At that time, his own aerospace industry can use The opportunity has developed!
"Chen, let's wait a few more years, our country's manned spaceflight will definitely start again." Qin Guan said.
