After a month of closed work at the Luhu Military Base, the work of Fang Yuan and the others was finally completed.

In the evening, the first solar furnace ignition test was conducted.

When the solar furnace ion jet engine erupted a long tail of flame, everyone's eyes widened and their mouths widened.

Everyone was excited, and after a busy month, the assembly of the solar furnace was finally completed.

The pace of human beings flying into the universe has lifted their legs.

The more stable and solid this step is, the more significant it will be for mankind.

In the future, such an engine flame tail will shine in the starry sky and fly into deep space with humans.

Today's ignition ceremony is only to test the completion of the assembly of the solar furnace, not a test flight.

There is still a lot of work to be done from the completion of the assembly of the solar furnace to the actual test flight.

However, the work of Fang Yuan and others has been completed, and the next step is the work of the Academy of Military Sciences, the Weapons Research Institute, and the controllable nuclear fusion scientific research team.

In addition, the avionics system, and other technical teams, should also join in and continue to work to improve the spacecraft step by step.

"The ignition ceremony is over, you can go home tomorrow, you go back tomorrow first, tell your mother, I will go back in a few days." In the afternoon, Fang Zhenguo arranged family tasks for Fang Yuan.

In the evening, everyone gathered for dinner in the workshop canteen.

"Professor, are we done? I received an order to go home tomorrow, but the spacecraft has not yet been tested. "Eve would love to fly a test flight.

"The assembly of the solar furnace has been completed, but the test flight is not so fast, and the performance of the solar furnace on the spacecraft needs to be tested first to check whether there are any hidden dangers. It will take a period of testing before it can be officially tested. Yang Yuping explained.

"Yes, if you think about it, this is the first manned spacecraft in all mankind to carry a solar furnace engine and fly to space. Before that, no such ship had ever been built. Everything has to be crossed by feeling the stones, so there is still a lot to test. Don't worry, you'll see the day when the Shenzhou flies to the stars. Wang Jiuliang took over the conversation and added.

"I really want to participate in the test flight." Evenunu mouth.

"Don't worry, when it's time for the test flight, I will definitely call you here." Yang Yuping was comforted.

Niu Dazhi has always had a question, held it for a long time, and then asked: "Professor, I've been looking at this spaceship for several days, and I feel that the shape is a little weird." ”

"What's weird?" Yang Yuping didn't understand what he was trying to say, but he still asked patiently and was ready to answer.

"It's kind of like an airplane, but it's a bit like a rocket, and I don't feel like it's going to fly." Niu Dazhi finally said the doubt in his heart.

Eve immediately covered her forehead, very speechless.

may be because of the frequent mutual scolding, Eve found that she could understand Niu Dazhi's doubts, rolled her eyes, and said loudly: "Because the Shenzhou takes off vertically!" ”

"Vertical take-off?"

"Yes, it's a vertical takeoff, like a rocket." Yang Yuping confirmed this.

The cadets of the military scientific research class couldn't help laughing: "It turns out that you have been here for so many days, and you don't even know that the Shenzhou is designed according to vertical take-off?" ”

"Nobody told me, don't you know how strange?" Niu Dazhi spread his hands.

He scratched his scalp and asked strangely, "Why do you want to take off vertically?" Is horizontal take-off bad? So many planes take off horizontally, and the technology of horizontal take-off should be better. Moreover, taking off vertically, people sit in it, isn't it uncomfortable? ”

Han Youwei pursed her lips and smiled, helping to explain: "There is actually a reason for the design of vertical take-off, because the goal of Shenzhou is to fly out of the earth and sail in space, so it is necessary to consider the possibility of landing on other planets in the future.

"Not every planet in the universe has air. An important condition for horizontal take-off is air, and without air, horizontal take-off cannot be achieved.

"Therefore, to go to the universe, horizontal take-off is an inevitable development trend."

Niu Dazhi laughed and said, "So that's the case." Just say that there is no air, and I understand. What a simple thing. ”

"You know a head." Eve still didn't forget to scold him.

Wang Jiuliang went on to add: "Actually, at the beginning of the design of the Shenzhou, the engine rotation design was originally considered. However, that would be more technically demanding, and the technology was not stable enough. In contrast, a fixed engine with vertical take-off is the safest design. ”

"The first generation of spaceships should be down-to-earth, step by step, and don't have to engage in all those bells and whistles." Fang Zhenguo's tone of voice was as if he had just communicated with the theater headquarters.

"So when is the test flight? When will we be able to come and see? Eve immediately asked.

"According to the work schedule, the test flight time is not too far, don't worry." Yang Yuping did not say the specific time.

Because there is still a high level of secrecy about the development and construction of Shenzhou, the specific time of the test flight cannot be said in advance.

In fact, Yang Yuping also guessed the approximate test flight time from the work schedule.

Fang Yuan glanced sideways at Fang Zhenguo and asked, "The headquarters will let us go back now, aren't you worried about the news of the Shenzhou leaking out?" ”

This time, there were more people who participated in the construction of the Shenzhou, and they had been working in a closed manner for the previous month, and no information had been leaked.

However, once so many people return home, it is difficult to guarantee that the news will not leak out.

It's not that some of these people leaked information, but it could also be that someone took advantage of this opportunity to leak information, and it will be difficult to trace it when the time comes.

Fang Zhenguo was not worried at all, and replied: "Since the headquarters let you go back, it means that you are not worried about this matter." ”

Fang Yuan understood what was going on as soon as he heard it.

Since the headquarters is not worried about intelligence leakage, it means to lower the level of secrecy.

Fang Yuan guessed that the headquarters would most likely announce some of the information about the Shenzhou.

And there's nothing surprising about that.

In fact, the news about Huaxia's development of spacecraft has been reported by foreign media for a long time.

Of course, those reports are chasing after the wind and have no substance.

However, everyone who knows a little about science knows that the development of a spaceship must already be underway.

Because the existence of the solar furnace is the key to the universe of civilization.

Now that you have the keys, it's impossible not to take this step.

Therefore, since Huaxia has built a solar furnace, it is imperative to study spaceships.

Everyone drank some wine, celebrated, and made an appointment to wait until the test flight of Shenzhou to get together.

After that, they went home the next day.

Coming out of the closed military base and returning to the city, the figure of the Shenzhou echoed in my mind, and I had a lot of emotion in my heart.
