It was that time that I watched the Shenzhou spacecraft fly into the sky, which determined her future development direction. She had been oscillating between weapons and aerospace www.biquge.info had not been able to make up her mind to make a decision. When she watched the successful launch of the spacecraft, the whole school suddenly burst into simple and excited cheers, and she instantly made up her mind in her heart.

Zhang Daoming clenched Ye Congyuan's hand and pursed his lips secretly, he didn't know what to be excited about, his daughter-in-law really didn't know anything. If it weren't for her to grow up with her research, he would have wanted to give her a high-level spaceship.

"When I was a freshman in high school, I was so excited to watch the live broadcast......" Ye Congyuan couldn't help but whisper to Zhang Daoming, she was so excited.

She was a freshman in high school and now a master's student, with a gap of almost ten years. And in the past ten years, she has made too many leaps from watching live broadcasts to watching live broadcasts.

Zhang Daoming touched her head and pondered for a moment, maybe this level of excitement was the same as when he finally ate her into his stomach on a candle night in the cave room?

A little unhappy that Ye Congyuan was so excited because of such a thing, but Zhang Daoming finally understood, so he quietly listened to Ye Congyuan whispering excitedly, and occasionally responded a few times.

At this time, Commander 0 called out the countdown, and there were only five minutes left before the spacecraft launch.

Ye Congyuan was even more excited, she held Zhang Daoming's name and continued to shake, the amplitude was much greater than just now,

"I regret not insisting on being an astronaut at that time, if I did, I would be the one in the spaceship now! I'm so excited! ”

Although the spacecraft is not equipped with a gravity field for the time being, it will be very difficult to be an astronaut, especially when the spacecraft accelerates, but for the sake of ideals, it is nothing to work hard!

Zhang Daoming took her hand, "There will be a chance, don't worry." ”

The leader standing next to him has not spoken since he came, which is very different from his previous image of talking and laughing.

I saw that his eyes were clear, and he kept staring at the manned spacecraft in front of him.

It can be called a behemoth, although it is not as large as a large cruise ship, but it is also the size of a Star Peak cruise ship.

Can such a behemoth really rise into the air?

All the spaceships launched in the past were launched in the form of rockets, and the current ones are also in the form of rockets, but they are much fatter and longer, and it is estimated that there are more than ten layers.

Can such a crude rocket -- oh no, a spacecraft really lift off and break through the atmosphere and out of Earth's gravity?

One looked at the spaceship, then looked down at the pamphlet with the parameters, and found it a little dreamy and unbelievable, so he decided to ask a reliable expert.

As for the reliable expert, the leader subconsciously turned his head to look in the direction where Ye Congyuan and Zhang Daoming were, "Yuanyuan, how much does this manned spacecraft weigh in its normal state?" ”

After asking, I saw that the young couple was chattering sweetly, and I couldn't help but feel that I had asked the wrong person, obviously there was an accompanying official next to him, and he should ask the accompanying official.

Fortunately, Ye Congyuan is a good comrade, she has never failed to give face to good people, so she stopped telling her excitement at the moment and said with a smile,

"The manned spacecraft being launched right now has a large payload, but the number of seats is only 100, and this number does not include the crew that will be set up. In principle, there are also separate beds, but at the moment this is the first launch of the new model spacecraft, so only 100 seats were made, plus other substances of the corresponding weight. ”

The leader nodded while listening, and began to beat the drum in his heart, the rough feelings are nothing, and the weight is really stunning. It was originally rough and clumsy to look at it and it was difficult to break through the atmosphere, and the weight of 100 beds was added to it, can this still be successfully launched?

After some calculations in his heart, the number one leader did not show any clues, and asked in a breezy tone, "If the corresponding bunks are added at that time, the size of the spacecraft will definitely increase, will this have an impact on the successful launch?" ”

Why do most of the launched spacecraft choose the form of rockets? That's because slender, pointy things have less resistance! As the size increases, the resistance experienced by the ship increases.

In this era when many countries have not yet been able to successfully launch rockets, is it really okay to suddenly make something bulky?

Ye Congyuan shook his head, "It won't have an impact, it's all within the scope of our calculations." In our calculations, the take-off weight of the spacecraft is 695 tons, the take-off thrust is 1000 tons, and the thrust that can be used for take-off acceleration is as much as 305 tons. As long as there is not much error in the values, the spacecraft will definitely be successfully launched. ”

The new manned spacecraft that will be launched will no longer be launched with traditional rocket fuel, but with light waves and wind power. This greatly reduces the weight of the spacecraft, and the take-off weight of the ship is also greatly reduced.

The take-off weight of the spacecraft the size of a small cruise ship in front of you is only 695 tons, which is about the same as the slender Long March 5, because the fuel used in the engine has changed, which greatly reduces the weight.

In fact, the take-off thrust is not the final value, and the current manned spacecraft use light waves and wind power to convert the propulsion of the generator, and the propulsion of the engine can be increased at any time in the universe to accelerate, and even reach the third cosmic speed and the fourth cosmic velocity......

The reason why we can't reach the fourth cosmic speed now is because there are still technical hurdles that have not been overcome.

The number one is an engineering student, but he can also understand Ye Congyuan's words, so he nodded at the moment, indicating that he understood.

In a word, no matter how heavy the spacecraft is, as long as the take-off thrust greatly exceeds the take-off weight, the spacecraft can be successfully launched. The take-off thrust is even greater, reaching the third cosmic velocity, and you can even fly out of the solar system and sail into the universe!

The official next to him held the pamphlet and kept looking at Ye Congyuan.

Sure enough, it was the scientists involved in the research and development, and they didn't need to look at the materials to say the truth. Come to think of it, she has calculated these data countless times, so she knows it by heart.

At this time, the number one spoke again, "What we can technically achieve now, how many people are allowed to carry manned spacecraft?" ”

Ye Congyuan replied, "Since we are leaving the earth for a long-distance roaming, we plan to design a coexistence mode of seats and beds. According to the technical level of our institute, it is now possible to set up 600 bunks. ”

Since there are already beds, the seats can be arbitrary, and if the seats are made into a single seat with a narrow footprint, the number of people can be increased.

However, the institute is currently divided into two groups, one group believes that it is not necessary to make it too comfortable, but should set up as many seats as possible to carry more guests; The other school of thought believes that after all, it is a sightseeing spaceship, and the more comfortable it is, the better.

Judging from the current intensity of the dispute, Ye Congyuan believes that the spacecraft will eventually move towards a hierarchical shipping system. For example, the first class cabin is luxurious and comfortable, and it is provided to the super-rich, and the following is gradually secondary. As for the worst, it is estimated that it is the same as the hard seat or even no seat on the train, just to give a foothold in the position.

It has always been a dream of mankind to be able to take a space odyssey, and it is estimated that it is only standing, and countless people are flocking to it.

600 bunks! Still with seat and bed! If you are separated, one person can only enjoy bunks or seats, then at least 1,200 people can be loaded!

The number one is excited, this is his political achievement in office!

In the future, he will go down in history with this epoch-making manned spacecraft!

As an excellent leader who has to deal with old foxes from all over the world all year round, the boss of the Luo family has strong self-control. Although he was very excited at this time, he was still very calm on the surface, and continued to speak,

"After this successful launch, how long will there be a second launch? How long will it take for a human to wander through space? ”

Ye Congyuan thought for a while, "Look at the production department, within the third cosmic velocity, our R&D department has no technical barriers." If the production department can quickly produce the spacecraft, then it can be ready for a second launch or even officially carry human passengers into space. ”

The number one leader nodded again, and while quickly calculating how many years he still had in office, he made up his mind to allocate funds to the manned spacecraft production department, so that they could increase the investment of manpower and material resources and produce the manned spacecraft as soon as possible.

Several officials next to him pricked up their ears to listen to Ye Congyuan's words and quickly wrote them down.

That's a lot of knowledge!

Zhang Daoming didn't like Ye Congyuan chatting with the boss of the Luo family and ignored him, glanced at his hand, and was about to speak sarcastically.

Ye Congyuan understood Zhang Daoming, and when he saw this, he hurriedly pinched Zhang Daoming's fingers, and couldn't stop making his eyes look at him.

The number one represents the dignity of a country, and although he does not understand a lot in scientific research, he is absolutely qualified or even excellent in politics, and such a person must not be ridiculed in front of others!

Zhang Daoming was unhappy, but looking at his daughter-in-law's threatening eyes, he could only stop stupidly.

The boss of the Luo family is a good person, and he knows people's emotions very well, so he naturally knows that Zhang Daoming is very unhappy at this time. But he didn't pay attention to it, he just glanced at Zhang Daoming and smiled secretly in his heart, and sure enough, he was still stunned, and even loved to eat this little vinegar.

However, only at such a young age, jealousy can be so undisguised.

I have to say, it's good to be young!

As a beast, Zhang Daoming naturally sensed the gaze of the leader, and he grinded his teeth in his heart, feeling that this person was very much like the fox that the human world said.

At this time, Commander 0's voice sounded again, indicating that there was still a minute before the launch of the spacecraft.

Everyone present suddenly stopped talking, and looked at the behemoth in the distance with bated breath.

One minute actually passed quickly, but everyone present felt that today was an extraordinarily long minute.

It seemed like an hour, a month, a year.

When the countdown sounded, the relatively older people present couldn't help but think of the Chinese New Year when they were children.

The mood at this time is almost the same as the mood of the New Year.

“10――”

“9――”

The countdown voice was a little hoarse, but the tone was sonorous, and it sounded like a world-class tenor setting the mood.
