On the eve of the anti-eagle movement: the country urgently called me back home!

17.68 meters high, 1.65 meters in diameter, 3.56 meters in wingspan… Looking at the huge monster, Gan Lao was stunned.

“Mr. Qian, this is the No. 1 missile. The warhead weighs 1.3 tons, the flight time is 442 seconds, the maximum range is 600 kilometers, the missile take-off weight (total weight) is 20.4 tons, the maximum flight speed of the missile when the engine is turned off is 2165 meters/second, and the maximum ballistic altitude is 168 kilometers.……”

Zhao Tianming introduced it briefly.

Gan Lao looked incredulous:”This is Dongfeng 1… the pride of our country… I never thought… I really didn’t expect it!”

“You actually created it!!”

“Good, good… That’s great!”

Gan Lao was so excited that he was talking incoherently, moving back and forth, staying next to the Dongfeng missile, and circling it!

“1, 2, 3, 4… so many.”

Counting the number of assembled missiles, Gan Lao’s face was filled with pride and pride.

“Let ‘s go and have a look at the rocket engine production line!”

This is the place that Qian Lao is most interested in.

Zhao Tianming:”Qian Lao, the solid rocket engine production line is not in the 101 Arsenal, it’s in the automobile factory… If you want to see it, let’s go another day.……”

Qianlao: ? ?

? What? The missile solid engine is produced by the automobile factory?

Jiang Chen:”Qianlao, how is it? The No. 1 missile I developed……”

“Impeccable, great!” Gan Lao:”It is hard to imagine that our country can surpass the Eagle Sauce in the missile track!”

“Jiang Chen, you are such a genius!”

Jiang Chen’s vanity was greatly satisfied after receiving the recognition from Qian Lao.

Qian Lao:”Today I am really enlightened… Our country’s current production technology level has completely surpassed the rest of the world. Just the lithography machine and computer technology… are enough to keep Western countries chasing for decades.……”

“The level of development of the flower-growing countries is higher than I thought… If I hadn’t returned to China, or if I hadn’t seen it with my own eyes, I couldn’t imagine that rabbits have become a world power.……”

Finally, Gan Lao sighed:”Alas, I thought I would develop my expertise after returning to China… Now it seems… a hero has no place to use his skills!!”

Jiang Chen:”Gan Lao, don’t say that. I called you here today mainly to let you know the current development status of the 073 missile in our country. You know, aerospace and satellites are our next goals!”

“I won’t talk about the importance of this aspect. Dongfeng 1 is nothing. There will be Dongfeng 2, Dongfeng 3… Next, we need to work together to develop the aerospace industry.……”

Qian Lao was relieved:”Jiang Chen, thank you for laying such a good foundation… I believe that it won’t be long before Rabbit’s aerospace industry will have a qualitative leap.……”

“I feel relieved with you here!”

Then, the two of them made a detailed plan for the current development of missiles and how to solve the problem of satellite launch power.

Qian Lao made a suggestion: if one solid rocket engine is not enough, then two.

Jiang Chen also agreed, but he had to solve the problem of how to reach the first cosmic speed first.

The two were chatting about more in-depth terminology.

Qian Lao suddenly thought of a key issue:”Jiang Chen, we have all overlooked a problem. If we have a wind tunnel, then many missile parameters can be tested in the wind tunnel. In this way, more mistakes can be avoided… and losses can be reduced.……”

“So, the task at hand is: build a wind tunnel!!”

“Wind tunnel?”Jiang Chen:”I have already built it, right in the fighter production workshop……”

What?

Even the wind tunnel is finished? It

‘s really full of black technology.

“Let’s go and have a look.……”

Afterwards, Jiang Chen brought Qian Lao to the aircraft production workshop

“Is this the fighter jet we independently developed?”

“Yes, we call it Wuye… However, it has been upgraded to produce farmers… In addition, the second generation of fighters is still under development……”

A few simple words surprised Qian Lao again.

The second-generation fighter is already in the process of development?

As a leader in aerodynamics and the creator of the world’s first jet aircraft, the United States has been the world’s leader in aviation for more than a decade.

If Jiang Chen can really take the lead in developing the second-generation fighter, it will definitely be enough to turn Rabbit from a follower to a pioneer.

The development of fighters alone is enough to crush the world.

The first generation of fighters was in the late 1940s and early 1950s, and representative models include the Eagle’s F-86 and the Bear’s MiG-15.

This generation of fighters uses large-caliber aircraft machine guns (cannons) as weapons, can engage in close-range air combat in the transonic zone, has a practical ceiling of about 15,000m, uses a medium-swept wing, and has a thrust-to-weight ratio of 4:5.

Later turbojet engines with afterburners are equipped with optical sights, and some aircraft are equipped with interception radars with an effective range of only a few thousand meters. Rabbit’s first-generation fighters have”Wu Ye””、”Farmer” (J-6) and other models.

In general, the first-generation fighters have insufficient ceiling, acceleration, and climb rate, and their weapon systems and airborne equipment are relatively simple, so their combat capabilities are still far from satisfactory.

The second-generation supersonic fighters emphasize”high altitude and high speed”, with a ceiling of more than 20,000 meters and a maximum speed of more than twice the speed of sound. Some high-altitude interceptors have a ceiling of up to 30,000 meters and a speed of more than 3 times the speed of sound.

Therefore, in order to ensure performance requirements, efforts must be made in aerodynamic design.

It is necessary to transition to a sharp head and air intake on both sides to improve low-speed performance. The variable swept wing was adopted.

In terms of airfoil, thinner supersonic airfoils were adopted. The leading edge of this airfoil was sharp and symmetrical. Common ones include diamond airfoils, hexahedral airfoils, and double convex airfoils.

Moreover, the air combat weapons of the second-generation fighters are mainly second-generation air-to-air missiles, equipped with second-generation radars, and some are also equipped with fire control systems with interception capabilities. The second-generation supersonic fighters are fast, have high ceilings, and have strong firepower, so their combat capabilities are greatly improved. Its appearance will make the first-generation supersonic fighters withdraw from the stage of history.

At this time, Gan Lao looked at Jiang Chen with burning eyes and admiration!

“Jiang Chen, you are truly the pioneer of the rabbit space industry……”Qian Lao:”Wind tunnel, fighter jets, and missile solid engines… You have left us a rich legacy!”

Jiang Chen remained humble:”Qian Lao, the wind tunnel I built is a high-speed wind tunnel, which is still a long way from the wind tunnel required by our aerospace industry. Therefore, we need to upgrade the wind tunnel as soon as possible. Only when it reaches supersonic speed… it is best to reach hypersonic speed.……”

Supersonic wind tunnels are not the best, hypersonic wind tunnels are the best

“Okay, I’ll find a way to do this!” Gan Lao patted his chest and said,”With such a good foundation, it shouldn’t be a problem!”

“”Then please!”

With the supersonic wind tunnel, it will play a vital role in the development of second-generation fighters, third-generation fighters, and even fourth-generation fighters.

Especially at this stage, the peninsula war has entered a stalemate, the Eagle Sauce is unable to launch a large-scale war, and the Rabbit has no intention of fighting.

Fighter sneak attacks, logistical strikes, and precision bombing have become means of game.

To put it bluntly, whoever has advanced technology can crush

“Jiang Chen, the problem of centrifuge materials has been solved. What should we do next?” (To read exciting novels, go to Faloo Novel Network!)

“Bring the drawings here and let me have a look!”

Qiu Siyan handed the drawings to Jiang Chen, who pointed at them and said,”Give the core rotor to Shen Changchun and have him produce it as soon as possible… How’s the mold going?”

“It has been implemented!”

“OK, next, after all the parts are completed, you can assemble them.……”

“Good!” Qiu Siyan left after reporting her work.[](Jiang Chen turned around and saw Qian Lao looking at him in shock:”Qian Lao, what’s wrong?”

“Just now, you said…the centrifuge has entered the mold pouring stage? ? So fast?”

“Yes, in about a month, the centrifuge should be ready!”Jiang Chen:”So, I have to solve the problem of nuclear power generation as soon as possible!”

Hiss!

Jiang Chen solved the centrifuge problem so quickly?

Then, Jiang Chen exchanged the blueprints of 2 missiles and the supersonic wind tunnel from the system and handed them to Gan Lao.

“Mr. Qian, thank you for your hard work on these two research projects.……”

Looking at the drawings of missile No. 2 and supersonic speed, Qian Lao’s hands trembled uncontrollably. These two drawings seemed to be more important than Mount Tai.

As an expert in aerodynamics, Qian Lao saw the importance of these two drawings at a glance.

Missile No. 2 is 20.9 meters long, 1.65 meters in diameter, 29.8 tons in takeoff weight, and uses a first-stage liquid-fuel rocket engine with a maximum range of 1,500 kilometers.

It can carry a 1,500-kilogram high-explosive warhead, or a 1,290-kilogram nuclear warhead with a power of 20,000 tons of TNT equivalent.

Range of 1,500 kilometers… can carry a 20,000-ton nuclear warhead.

The range is increased from 600 kilometers of Dong 1 to 1,500 kilometers of Dong 2?

Looking at the parameters of missile No. 2, Qian Lao felt like he had found a treasure, and his excitement could not calm down for a long time.

It turned out that Jiang Chen had already reserved space for the atomic bomb before it was developed?

At this moment, Qian Lao suddenly felt Jiang Chen’s careful layout and design.

He was defeated! I was so impressed.

There were also supersonic wind tunnel drawings…

The Mach number M of the airflow in the wind tunnel test section was between 1.4 and 5?

Qian Lao was shocked again!

At this stage, supersonic wind tunnel experiments are an indispensable part of aircraft development.

It not only plays an important role in the research and development of aviation and aerospace engineering, but also is indispensable in the fields of transportation, housing construction, wind energy utilization, etc. with the development of industrial aerodynamics. With this experimental method, the flow conditions are easy to control.

During the experiment, the model or object is often fixed in the wind tunnel for repeated blowing, and the experimental data is obtained through measurement and control instruments and equipment.

Of course, it is also very difficult to build a supersonic wind tunnel.

When the wind speed of the wind tunnel is below 1.2 times the speed of sound, the wind tunnel is relatively easy to build. Simply put, you only need to use a large electric fan to blow it.

And even if the required wind speed exceeds the speed of sound, you only need to use a Lava1 nozzle to convert the subsonic airflow into a supersonic airflow.

But when the airflow speed is required to be higher, even when the wind speed reaches more than ten times the speed of sound, this kind of wind tunnel is obviously not enough.

Because the ability of the fan to blow air is limited (to be precise, the ability to compress air), but extremely high wind speeds require a huge air pressure difference, so if you want to pursue a wind tunnel with more wind, you still have to think of a way.

But even with a pressure tank, the wind speed of the wind tunnel can only hover below 5 times the speed of sound.

And the real hypersonic aircraft or spacecraft re-entering the atmosphere are flying at a speed of more than ten times the speed of sound, so we have to think of new ways to create a wind tunnel with a higher speed.

At the beginning, Qian Lao and the scientists of Eagle Sauce focused on the ultimate art: explosion when they were researching.

Because, when the explosion occurs, due to the instantaneous burst of energy, huge pressure will be generated, and such pressure can also be used to generate high-speed airflow.

Depending on the explosion method, the speed of the airflow generated is also different.

For example, a device that generates high-speed airflow by burning hydrogen and oxygen can generate airflow at 2-5 times the speed of sound.

In addition, there is a way to generate shock waves through huge electric arcs.

Eagle Sauce scientists are currently studying high-speed wind tunnels powered by arc shock waves.

A super capacitor that can discharge 600,000 amperes of current can generate airflow of up to 40 kilometers per second at the moment of discharge.

However, this kind of wind tunnel that uses explosions to blow out high-speed airflow has a very big flaw: the duration of the airflow is too short, and it is not enough for the aircraft to generate lift.

Therefore, the research and development of supersonic and hypersonic wind tunnels has always troubled scientists in the United States.

Before seeing the drawings, Qian Lao had never been able to solve the problem of supersonic speed.

However, after seeing Jiang Chen’s drawings, he actually adopted a return to nature approach:”If the wind can’t come, then I will go over”!

Use a very high relative speed to obtain a high wind speed.

Simply put, although the airflow speed is not high, if I face the airflow and make the object being tested move, can’t I get a very high wind speed?

Therefore, the wind tunnel designed by Jiang Chen is no longer short and compact, but very, very long, so that high-speed airflow and high-speed objects can be shot out from both sides, so that they can move relative to each other and obtain a very high relative speed. The added wind speed is about 4 miles per second, and the speed at which the object is shot out can be as high as 9 kilometers per second.

Therefore, the relative movement speed of the two can reach 13 kilometers per second-thus achieving a research capability of 40 times the speed of sound.

At this moment, Qian Lao had to admire Jiang Chen’s genius design.

“Jiang Chen, did you design this?”

“Yes, there may be some defects. I hope Mr. Qian can check it.……”

“A strong general has no weak soldiers. I won’t embarrass you.……”Qian Lao said with great confidence.

After Jiang Chen returned to the office, the system notification sound rang in his mind again.

【Ding, congratulations to the host for completing the mass production of lithography machines and artillery anti-radars. You will be rewarded with a 500-megawatt nuclear steam turbine generator, U-2 high-altitude strategic reconnaissance aircraft production drawings and principle structure drawings, and 90 million points!】
