Comprehension Against The Sky, Graduation Project Nantianmen Project!

wind tunnel!

These two words may be unfamiliar to many people.

But for researchers in the aerospace field, it is an unavoidable topic.

A wind tunnel is a laboratory for scientific research on aerodynamics.

It is the cradle of aircraft!

A concatenated definition is——

Wind tunnels are large tubes with air flowing inside them.

simply put--

The wind tunnel simulates the flow of air around aircraft or objects and various complex flight states in the air by artificially generating and controlling airflow.

It is a pipeline-shaped test equipment that can measure the effect of airflow on objects and observe physical phenomena.

It is the most commonly used and effective tool for aerodynamic testing.

It is a "green channel" for the development and production of modern aircraft, missiles, and rockets.

The wind tunnel can also be seen as artificially creating a "sky" on the ground.

That is to say, with wind tunnels, aerospace vehicles such as airplanes, ground experiments can be carried out!

Instead of running to try every day, and then watching the aircraft fall down.

as far as I can tell.

The existing wind tunnel laboratory in China.

It is far from meeting the needs of the Xuannv and Baidi fighters that Luo Fei wants to design.

"Zhao Fei, hurry up here."

Professor Cheng sighed, said something to Zhao Fei, and left the laboratory with Luo Fei.

come back to the office.

Professor Cheng asked Luo Fei:

"Theoretically, what is the speed and altitude of the two fighters designed by your team?"

He needs to know more about performance to know what kind of wind tunnel he needs.

Luo Fei didn't even think about it, and said directly:

"Xuannu and Baidi are products of the Nantianmen plan."

"But at the beginning of the design, my team and I took into account the original technical level, especially the limitations of materials."

"Currently, Baidi is temporarily targeting the F-22, and some are targeting the F-35."

"As for Xuannv, for the time being, I can only target the X-47B UAV of Biao Chou Country."

"Needless to say the height, it's just going for the air-space fighter."

"In terms of speed, the maximum flight speed of the first-generation Baidi experimental model must be at least Mach 3 or higher."

"As for the Xuannv UAV, it must be flying at supersonic speed."

"If it goes out of the atmosphere, the speed must be more than Mach 10!"

Although Professor Cheng had a hunch in advance.

The two models designed by Luo Fei, in terms of theoretical data, will definitely not be lower.

But such an exaggeration is still a bit shocking.

You know, the maximum flight speed of the F-22 is only Mach 2.25.

Even so, the whole world is afraid to speak.

As soon as Luo Fei came up, Baidi's maximum flight speed exceeded Mach 3.

This is to get rid of the F-22!

but!

It should be said that it is right to kill the F-22!

And Xuannv.

The Ugly country's X-47B is only at high subsonic speeds, not even supersonic speeds.

"its not right."

After being shocked for a moment, Professor Cheng suddenly realized that Luo Fei had something to say:

"What about the range? What about the combat radius?"

After asking, Professor Cheng immediately came back to his senses and suddenly realized:

"That's right, your two fighters both use the electric propulsion system of the basic cold fusion device."

"The combat radius will basically no longer be limited by fuel!"

"hiss!"

Speaking of this, Professor Cheng has a headache.

It is the wind tunnel laboratory that limits the progress of Luo Fei's scientific research!

After thinking about it, Professor Cheng said:

"The JF-22 ultra-high-speed wind tunnel that was just established at the beginning of the year will definitely not be used."

"At that time, I can only apply for you for the most advanced wind tunnel at present..."

Having said that, Professor Cheng looked at Luo Fei and said:

"My personal suggestion is that you advance the research and development of the Xuannv drone, after all, it doesn't need people to drive it."

"At that time, install the power and test the flight first."

"I believe that as long as Xuannv can reach half of the theoretical value you designed, it will be enough for you to apply for any national laboratory without hindrance!"

Luo Fei couldn't help but nod at Professor Cheng's words.

In the field of scientific research, especially in this kind of national scientific research field.

Strength is fundamental.

as far as I can tell.

It's really an airplane, not Luo Fei's pantao laboratory.

There are mainly Shen Fei and Cheng Fei.

And speaking from the current well-known strength.

Luo Fei wanted to directly compete with them for the wind tunnel laboratory, but it was still a bit troublesome, and he needed to spend some time talking.

And once Xuannv goes to heaven.

Then all the problems will no longer be problems!

Xuannv's power system alone is enough to make the country tilt all resources!

Luo Fei understood Professor Cheng's meaning, nodded and said:

"Okay, I see. When I go back, I will first stare at Zhang Tao's Xuannv project."

"besides."

Professor Cheng looked at Luo Fei seriously, and said:

"This research on the graphene magic angle, you have time to participate in it."

"The other is the new high-temperature-resistant and high-resistance ceramic material. After Zhao Fei's test data comes out, write the paper quickly."

"As long as these two things come out, Luo Fei, you can graduate with me anytime!"

Luo Fei is not surprised by Professor Cheng's words.

But the next sentence was a surprise.

Just listen to Professor Cheng say:

"I seem to have overlooked a problem."

"You are based on cold nuclear fusion device and electric propulsion system. Will you be able to develop it independently soon without Baidi and Xuannv?"
