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

As an academician, he has paid attention to every aspect of the design of Xuannv No. [-].

In-atmospheric take-off and landing, in-atmospheric cruising, and space flight...

It is no exaggeration to say that with this set of design schemes, even with the same power system, the performance of Xuannv No. 50 is more than [-]% higher than that of Xuannv No. [-]!

Lu Yongchang shook his head with a wry smile.

"Academician Cao, have you forgotten the mission we arranged for Xuannv No. [-]?"

Cao Liangcai couldn't help but froze in place.

Lu Yongchang sighed softly, and said in a low voice: "The Xuannv-[-] series aerospace planes are mainly responsible for the transportation of materials in the solar system."

"That is to say, the main battlefield of Xuannv No. [-] is not on Earth."

"The moon, Mars, or the distant Kuiper belt are all its future destinations."

"In this case, do you think the original shape of the plane is still suitable?"

"Don't talk about the moon, just talk about Mars."

"The density of Mars' atmosphere is about 1% of that of Earth's. How much lift do you think such a wing can provide for it?"

"What a waste of space!"

Cao Liangcai froze in place.

Lu Yongchang shook his head and sighed, while taking another plan.

"Among the three plans, I prefer this one."

Cao Liangcai looked at the plan in front of Lu Yongchang.

It was proposed by one of his professors.

It can be clearly seen from the drawings that in order to pursue greater capacity, it completely abandons the traditional aircraft shape.

After removing the wings, widening the nose, and thickening the fuselage, the entire Xuannv No. [-] roughly looks like a cuboid.

The corners of Cao Liangcai's eyes twitched suddenly. This was the first plan he vetoed.

He softly raised his doubts: "Professor Lu, with such a shape, can it really take off on the earth?"

This style that violates common sense has completely overturned Cao Liangcai's slightly rigid thinking.

Lu Yongchang looked carefully at the blueprint in his hand, and his eyes showed some satisfaction: "Of course!"

"As long as it's powerful enough!"

"With the second-generation nuclear fusion and the second-generation Hall thruster, I believe that the power will definitely not be a big problem!"

"With such a design, it can shoulder the heavy responsibility of material transportation in the solar system!"

Cao Liangcai fell silent.

As an academician, he never expected that his design drawings would be inferior to that of a professor under him!

Lv Yongchang immediately noticed the disappointed look on Cao Liangcai's face, he stood up, smiled and patted him on the shoulder.

"Old Cao, your thinking is restricted."

"Since we feel that we have stepped out of the earth, sometimes we must learn to break common sense!"

Cao Liangcai took a deep breath, and turned his eyes to another design drawing on the table: "Professor Lu, how about another design drawing?"

"What do you think?"

Lu Yongchang, who heard this question, also fell silent.

After a long time, he twitched the corners of his mouth, smiled wryly and shook his head.

"To be honest, I don't know very well."

"This blueprint...who came up with it?"

Hearing Lu Yongchang's question, Cao Liangcai cast his questioning eyes on the people in front of him.

A group of professors and academicians turned their eyes away one after another, indicating that it had nothing to do with them.

A few seconds later, a young voice sounded from the corner.

"Professor Lu... I made this plan."

All eyes turned to the direction where the voice came from.

I saw a researcher in his 30s standing in the corner, carefully raising his right hand.

A strange color flashed in Lu Yongchang's eyes.

"What's your name?"

"Tao Yuda."

The moment he heard this name, Lu Yongchang froze in place.

"Tao Yuda... you wrote the paper on sonoluminescence and controllable nuclear fusion?"

Tao Yuda froze for a moment, then nodded with a smirk and said, "Professor Lu, have you read that paper?"

"That's what I wrote blindly when I was a graduate student..."

Lu Yongchang's eyes became more strange.

The relationship between the two can be detected at the postgraduate level... This scientific research intuition is incredible!

No wonder such an "outrageous" plan can be proposed!

That's right, it's outrageous!

Lu Yongchang reached out to pick up another document on the table, and examined it carefully.

According to Tao Yuda's design, Xuannv No. [-] is a standard sphere.

It has to be said that such a design can not only reduce the resistance in the atmosphere, but also maximize the volume.

but……

The corner of Lu Yongchang's mouth twitched slightly.

"With our current level of technology, we shouldn't be able to make such an aircraft, right?"

Tao Yuda scratched his head in embarrassment: "Professor Lu, this is just an inspiration of mine, don't worry about it!"

Lu Yongchang gave Tao Yuda a meaningful look.

inspiration.

Inspiration again.

It has to be said that after entering space, the spherical starship may be the final development direction in the future.

This Tao Yuda's inspiration has been correct at least twice!

"zero!"

"Help me verify these two plans."

"Suspend the rest of the unnecessary calculation items, and fully calculate them!" Lu Yongchang added softly, "I want to get the results in the shortest possible time."

Just as the voice fell, an electronically synthesized voice sounded in the conference room.

"Yes, Professor!"

After getting a zero reply, Lu Yongchang gently pulled Cao Liangcai beside him, and said in a low voice: "Old Cao, come out with me!"

……

Cao Liangcai looked at Lu Yongchang in front of him suspiciously.

He didn't understand Lu Yongchang's sudden move to pull him out of the conference room.

Lu Yongchang looked past Cao Liangcai and looked at the closed door of the conference room, as if he could penetrate it.

"Old Cao, focus on cultivating Tao Yuda next."

Cao Liangcai choked slightly: "You mean..."

Lu Yongchang said lightly: "This kid...is a material for scientific research!"

Chapter 114 Code Name: Yinghuo

Cao Liangcai's pupils shrank slightly, obviously surprised by Lu Yongchang's words.

"you sure?"

He looked at Lu Yongchang in front of him with a face full of surprise, and said in a low voice: "This kid, he is usually quiet. If he hadn't taken the initiative to stand up today, I would have even forgotten that there is such a person in the laboratory!"

Lu Yongchang nodded solemnly.

"Old Cao, trust my vision."

……

After returning to the conference room, Cao Liangcai looked at Tao Yuda deeply.

"Cao... Academician Cao?"

Tao Yuda stared at Cao Liangcai for a few seconds with trembling eyes, quickly lowered his eyes, and asked in a low voice, "Is there something wrong?"

Cao Liangcai shook his head slowly, with a smile on the corner of his mouth: "It's nothing."

"Tao Yuda... right?"

"Are you interested in being my deputy?"

Hearing this, Tao Yuda's breathing became short of breath.

"Yes! I am willing!" Tao Yuda nodded vigorously with excitement in his eyes.

Before Cao Liang could continue to say something, an electronically synthesized voice sounded in the conference room.

"Professor, the simulation results are out."

"Plan One was a success."

Lu Yongchang's expression remained the same, without any change.

He had expected this result a long time ago.

only……

"What is the reason for the failure of the spherical structure?" He asked in a deep voice.

There was a bit of weirdness in Zero's simulated tone: "...Professor, our current materials are not strong enough to support an aircraft of this structure."

"Not only that, but the current manufacturing process is not enough to make such a vehicle."

Sure enough.

Lu Yongchang's eyes showed a bit of surprise.

"Now that the plan has been finalized, Zero, from now on, we will do our best to manufacture the prototype of Xuannv No. [-]."

……

half a month later.

A press conference was quietly held in the Great Hall of Xia Kingdom.

The launch event was organized by NASA.

This is also the first real press conference held since the establishment of NASA.

Such a gimmick naturally attracted the attention of a lot of media.

As a reporter from Xiaguo News Agency, Zuo Chen arrived at the press conference early after receiving the invitation.

Looking at the half-empty chairs at the scene, Zuo Chen couldn't help but froze in place, then raised his wrist to check the time.

The time is right!

So what's the situation?

Why are there so few people...

"Brother Chen?!"

Just as Zuo Chen was standing there wondering if he had gone to the wrong venue, a familiar voice came.
