It's reasonable for me to have a two-way foil for a second-level civilization, right?

Lu Yongchang: "...about 10 tons of thrust."

"10 tons? So little?" Hong Qiming frowned instantly.

"I remember that the maximum take-off thrust of the CF747 engine of the Boeing 6 can reach about 105 tons?"

"10 tons of thrust, for aerospace aircraft, will it be a little less?"

Lu Yongchang chuckled lightly.

"Minister Hong, you still didn't understand what I said."

"The thrust of a single Hall propulsion unit is 10 tons."

"I never said that there can only be one Hall propulsion unit on an aerospace plane!"

Hong Qiming's pupils suddenly shrank!

He swallowed slightly, and said hesitantly: "You mean... we can install a large number of Hall propulsion units on an aerospace plane?"

Lu Yongchang nodded slightly, then shook his head quickly.

"Huh?" A trace of doubt flashed in Hong Qiming's eyes, "Yongchang, what do you mean by nodding and shaking your head...?"

Lu Yongchang pondered for a moment, then slowly said: "That's right. Although the Hall propulsion unit can be installed without limit in theory, this is not the case in reality."

"We need to comprehensively consider the size and purpose of the aerospace aircraft and calculate a reasonable thrust."

Hong Qiming nodded half-understood, then waved his hands and said, "Hey! Why are you telling me about these professional things?"

"Just tell me a word, how many Hall propulsion units are you going to install on the first aerospace plane, I have to report to the chairman of the congress."

Lu Yongchang laughed dumbfoundedly, shook his head and said, "Ten!"

Chapter 64 Have you ever heard that bricks fly with great strength?

Hearing Lu Yongchang's words, Hong Qiming hadn't reacted yet, but Cao Liangcai couldn't help but exclaimed.

"Ten Hall propulsion units?"

"Didn't we say that five propulsion units are enough?!"

"Huh?" Hong Qiming narrowed his eyes slightly, and looked at Lu Yongchang with a strange expression.

"Yongchang, you can't talk nonsense about this thing. When the chairman of the congress blames me, I can't help it!"

Lu Yongchang shook his head with a wry smile, and hurriedly explained.

"Initially our plan was indeed to install five Hall propulsion units."

"Although the thrust of 747 tons is not as good as that of Boeing [-], it is enough for smaller aerospace planes."

"It can even be said to be more than enough."

Hong Qiming's eyes became more suspicious: "Then why..."

Lu Yongchang pondered for a moment and then said: "In the original design, the maximum flight altitude of the first-generation aerospace plane was within 2000 kilometers, that is, the Earth's low-Earth orbit."

"Later, I thought about it carefully. Since I am going to make an aerospace plane, why not just make the best one?"

"It's better to double the number of Hall propulsion units and enlarge the aircraft skeleton."

"Although the manufacturing difficulty may increase a little, the performance of this first-generation aerospace aircraft will be greatly improved!"

"According to calculations, this aerospace plane will be able to take off directly from the ground to the moon."

"The fuel it carries will be enough to support two round-trip flights between the earth and the moon!"

Hong Qiming gasped suddenly!

Good guy!

What did he hear? !

Take off directly to the moon?Can you go back and forth twice? !

Looking at Academician Cao Liangcai's wide eyes, Hong Qiming suddenly felt that he was losing control of the situation.

"Etc., etc!"

"Professor Lu, are you sure you are talking about verified data?"

Seeing Lu Yongchang nodding in affirmation, Hong Qiming's pupils shrank slightly, and then he reached out and took out his cell phone from his pocket.

"Wait a minute, I need to report the situation to the chairman!"

……

A few minutes later, Hong Qiming hung up the phone with a complicated expression.

"What did the Speaker say?"

Lu Yongchang asked Hong Qiming curiously.

Facing Lu Yongchang's question, Hong Qiming glanced at him with a strange expression, then slowly shook his head.

"I really don't know what ecstasy soup you poured into the chairman of the council."

"Member Li asked me to fully cooperate with your research plan. If you need anything, just say it."

Lu Yongchang was slightly taken aback, as if he had thought of something.

His eyes moved slightly, and he said directly: "Minister Hong, so I really have a problem that needs your help!"

Hong Qiming's voice suddenly stopped, and his expression became more and more strange.

"You can tell, but I have agreed in advance, we will not do things that violate the principles!"

Lu Yongchang: "..."

With a wry smile, he stretched out his hand and touched the tip of his nose, and said angrily, "You think highly of me, Hong Bu. I dare not do something that violates the principle!"

"Come back to business." Lu Yongchang looked a little serious, "The first-generation aerospace plane lacks three pilots!"

"Pilot?"

Hong Qiming waved his hands nonchalantly and said, "This is a trivial matter."

"When the time comes, I'll take you directly to the Air Force Brigade to pick someone up!"

To Hong Qiming's surprise, Lu Yongchang shook his head and rejected his proposal: "Hong Bu, I'm afraid this won't work!"

"The pilots of aerospace planes have higher requirements. I'm afraid the Air Force Brigade...can't meet its requirements."

Hearing Lu Yongchang's words, a look of astonishment flashed across Hong Qiming's face.

WTF?

The pilots of the Air Force Brigade can't meet the requirements?

He glanced at Lu Yongchang in surprise, pondered for a moment and said, "Yongchang, don't you know the pilots in the Air Force Brigade?"

"If ordinary pilots can't meet the requirements, you can definitely pick those golden helmet ace pilots!"

"Don't worry, those pilots are absolutely skilled!"

Lu Yongchang smiled wryly and shook his head: "It's not about flying skills."

"Huh?" Hong Qiming became more and more confused.

"According to my expectations, this aerospace plane needs to perform multiple missions to the moon."

"In my opinion, flying skills are a secondary option." Lu Yongchang said meaningfully, "Sufficient space flight experience is what aerospace pilots need most!"

Unlike ordinary planes in the atmosphere, aerospace planes are powerful enough to easily handle most unexpected situations in the atmosphere.

After all, there is an old saying that goes, strength is great and bricks fly!

What aerodynamics, nonexistent!

As long as the power is strong enough, even a brick can fly you out of the solar system!

In addition, during the mission of the aerospace plane, most of the time is outside the geosynchronous orbit.

Therefore, sufficient space flight experience has become one of the prerequisites for aerospace pilots!

After listening to Lu Yongchang's explanation, Hong Qiming nodded slightly.

That's it!

"In that case, I'll go to Xiaguo Astronaut Research and Training Center to help you have a look."

"When the time comes, help you find three astronauts who have been in space, is this the head office?"

Hearing Hong Qiming's words, Lu Yongchang pondered for a moment, then slowly shook his head: "I'm afraid it's not enough."

"Minister Hong, don't forget, this aerospace plane is not a rocket, the pilot must take care of the flight mission in the atmosphere."

Hong Qiming clicked his tongue lightly.

This is troublesome.

It is necessary to be proficient in flying skills in the atmosphere and have sufficient experience in space flight...

There are also a host of other age and fitness requirements to meet...

Although no investigation has been done, Hong Qiming can still conclude.

Xia Guo should not be able to find talents who meet this standard.

Not to mention Xia Guo, it is estimated that it is difficult to find such a talent on the entire earth!

Hong Qiming's eyes moved slightly, and he said softly: "How about... I will pick three astronauts and send them to the air force base for training for a period of time?"

Lu Yongchang's eyes suddenly lit up.

That's a good idea!

But then a worry came to his mind.

"How long will this air force base training... take?"

Hong Qiming frowned, and slowly shook his head: "I'm not very clear about this."

"I reckon... half a year to a year is always needed!"

"No! It's too slow!"

Lu Yongchang frowned and glanced at the calendar next to him.

4 month 3 number.

"Give them a month of training time at most!" Lu Yongchang said decisively, "In a month's time, I guess Xia Guo's first aerospace plane can also be manufactured!"

Chapter 65 Space Station Project Canceled?

Xia Guo Astronaut Research and Training Base.

Bai Yixuan stepped out of the centrifuge cockpit in a nonchalant manner.

As a Xia Guo astronaut, overweight adaptive training is his daily fixed training program.

Although he has trained for countless days and nights, the pain caused by the centrifuge has not eased in the slightest.

He exhaled slowly, turned his head and glanced at the centrifuge behind him.

I don't know when Xia Guo's space station project will be completed.

Thinking of this, Bai Yixuan's eyes dimmed a bit.

Recently he heard some rumors.

The upper level seems to want to cancel the original space station project.

Even some planned manned space missions are at risk of being canceled at any time.

In this way... where is the future of these astronauts?

Bai Yixuan sighed deeply.

Just as he was tidying up his scattered mood and preparing to go to the next training facility, a broadcast sound came from the loudspeaker next to him.

"Bai Yixuan, Hong Fan, Xia Wanyi."

"Today's training mission is cancelled, please go to the lobby on the first floor immediately after hearing the announcement!"

Bai Yixuan's eyes moved slightly.

Hong Fan, Xia Wanyi...
