my scientific age

Chapter 290 I am waiting for you in the field of nuclear energy weapon research

In the office on the third floor of a classical building in the center of Berlin, Guderian, the commander of the armored corps and the second armored division commander, is sitting in a chair looking at the latest confidential documents, examining the contents with the strictest eyes.

The reason for this is because this is an initial design proposal for a '35-ton new tank' submitted by Krupp!
The entire initial design scheme of the tank adopts a conventional layout, with a total weight of 35.5 tons and a crew of 5 people. The body armor is composed of vertical main side and rear armor. The thickness of the main armor is 80 mm, and the thickness of the side and rear armor is 29 mm and 25 mm, all of which are Y-type. The composite armor composed of armored steel + carburized hardened steel, the actual protection of the main side rear armor reaches 110 mm, 40 mm, and 35 mm respectively.

The turret armor has the same design as the hull armor, both of which are vertical armor, and the actual protection power reaches 130 mm, 50 mm, and 35 mm respectively.

From the outside, this tank looks like an enlarged version of the No. [-] tank. It has nothing to do with it, but it is mature and reliable.

Guderian didn't care about Krupp's use of the tank's exterior design. In many cases, maturity and reliability are far more important than novelty.

The artillery system is developed by Rheinmetall Corporation, which is developing a new 48-caliber 75mm tank gun. According to Rheinmetall, this tank gun has the performance of penetrating 1000mm homogeneous armor at 70 meters and 500mm at 97 meters. , enough to meet the firepower index proposed by Guderian.

The power system adopts a Maybach gasoline engine with a total power of 580 hp and a unit power-to-weight ratio of 16.3 hp/ton.

The suspension system is simple, reliable and convenient for logistical maintenance. Krupp did not use the spring-balanced suspension of the No. [-] tank, but chose the Christie suspension.

This is a suspension system designed by American engineers. It is connected with large-diameter road wheels by independent cylindrical coil springs to achieve traveling and buffering force, which is suitable for tanks to travel at high speed.

Krupp made some improvements based on the original design. By arranging six pairs of road wheels, the driving wheel is placed in the front, the road wheel diameter is 850 mm, and the track width reaches 42 cm, so that the acceleration and top speed not only meet the design indicators, but also the ground passing The performance and off-road performance are also greatly improved.

The key is that the overall structure is simple and reliable, easy to maintain, and meets the requirements of the armored corps chief.

Of course, there is no perfect thing in the world, and there are gains and losses. The Christie suspension has the disadvantage of occupying a large body space and reducing space utilization.

Not bad.

Guderian nodded with satisfaction. Compared with the shortcomings of this suspension, it brings more advantages to make up for these shortcomings.

"Overall, this tank is quite satisfactory and meets my design specifications. Unfortunately, due to the requirements of stability and reliability, it is a bit conservative, and it is not as radical as Henschel's." Guderian looked at this 35-ton Krupp version The initial design scheme of the first-class tank, thoughtfully, give evaluation.

Henschel's initial design, which was submitted yesterday, struck Guderian's heart.

The firepower systems are all Rheinmetall's new 48-caliber 75mm tank guns. The power system uses Maybach 580 hp + torsion bar suspension. The most outstanding part of Henschel is the use of the inclined armor used by the main armor belt of the naval battleship. design concept.

Yes, sloping armor.

Henschel's plan is that the 85mm normal line of the first upper armor is inclined at 60°, and the 75mm normal line of the lower head armor is inclined at 55°. According to the mathematical calculation results, the final protection power of the first upper armor and the first lower armor of the design plan is terrifying respectively. 234.6mm and 181mm.

This is a full 234 mm of armor protection, and Guderian can't find any tank guns that can threaten it.

Can't find it at all!
Compared with Krupp's well-established vertical armor scheme, the actual protection power of 110 mm is too far behind the 234.6 mm protection power of Henschel's scheme.

Between the two, the difference is more than double.

There is no doubt that the engineers of Henschel are crazy and radical. When Guderian saw this inclined armor design yesterday, his heartbeat could not help speeding up a little, and he almost couldn't help but finalize the plan.

The concept of inclined armor design is actually not new. As early as in the development process of naval battleships, naval battleships of various countries have used this concept early to improve the protection of battleships.

Of course, it is undeniable that the company Henschel brought sloped armor from battleships to tanks for the first time.

The Krupp plan has been reviewed, and now, a question is placed in front of Guderian.

Who is it?

Henschel's group of genius engineers like madmen, the stable and reliable King Krupp, Guderian had to choose one and give it to Mustache.

Henschel’s aggressiveness can bring unprecedented terrorist protection to the new 35-ton tank, at the cost of potential hidden dangers and instability. Since there has never been a tank with inclined armor design in history, Guderian dare not mess around He made a decision that producing a new type of tank would cost a lot of money and resources, and he would be a sinner if the resulting tank was unreliable.

Krupp's stability allows this 35-ton tank to quickly transform from blueprints to production links and enter military service. Although the 110mm protection is far less exaggerated than the Henschel plan, it is more than enough to resist the firepower of tanks of the same period.

Guderian took out Henschel's plan from the drawer and stared at the initial designs of the two companies. He was quite entangled in his heart and kept thinking.

"It's hard to choose, it's really hard to choose... However, when it comes to Y-type armor steel, count the time, it seems that the giant freighter has arrived."

"Dong Dong!" At this moment, a crisp knock sounded on the door.

Hearing the knock on the door, Guderian immediately came back to his senses, put the two plans in the drawer, and said, "Please come in."

Opening the door, a young officer hurried into the office, came to the table, and raised his hand in salute: "General Guderian, top-secret emergency call."

"Immediately arrange a car for me to go to the high command." Guderian took the message and read the content. Suddenly, the whole person stood up suddenly, with a hint of ecstasy in his eyes, and ordered the young officer.

This top-secret message was nothing but the Y-shaped armor steel he had in mind.

The scheduled transaction has been completed, and the military attache Boll is flying to Germany with the Y-type armor steel formula and technical data.

This news is really important.

"Yes!" The young officer left without hesitation.

After the young officer left, Guderian placed the top-secret message, took a deep breath, and prepared to formulate the next wording, suddenly remembered something, turned his eyes to the drawer, and then took out two initial design plans for the new tank.

Since he can't make a decision, let someone who can make the decision come.

……

In the morning, Yu Hua, who had been out all night, quietly returned to Tsinghua Park, where the blockade was lifted under the easing of the situation in Peiping. The Japanese 'the situation did not expand' and retreated, causing the tension in Peiping to drop sharply, and many universities in Peiping basically lifted the previous blockade. , and quickly arrange for students to go home for vacation.

Due to the Lugouqiao Incident, whether it is National Tsinghua University, which was the first to launch university entrance examinations, or Peking University and Nankai University, the summer vacation of students has been postponed. Students, most of the out-of-town students have not left school.

Back at school, Yu Hua didn't go to the mechanical engineering laboratory to find Professor Zhuang, but went straight to the nuclear physics laboratory. Today is No. 11, and tomorrow is the day he agreed to go to the base area. He has to arrange some things.

The introduction of military and local guidance and German-made mechanical processing equipment all need to be handed over to the organization through the identity of the vest Zhang San.

"This should be the last time I use Zhang San's identity. If I continue to use it, there will be no accidents and I need to use a new vest." On the way back to the laboratory, Yu Hua thought silently about Zhang San's vest, and continued to use it. It is not appropriate, and there is no need to put yourself in a dangerous situation in pursuit of some unrealistic sense of vanity.

Zhang San's vest, it's time to give up.

The name of the new vest has not been decided for a while, but it is not important, Yu Hua shook his head gently, thought about it, and stroked the next thing to do.

I have to go home later and arrange Xu Rui, Xu Xue and Yuanyuan properly.

Yuanyuan was young, so it would be best to leave it to the organization. In Xu Xue's case, this girl has already studied medicine under the teacher Tan Lao. According to the future development, it is the best choice to leave Beiping and go to the base area. You have to ask Xu Xue what she thinks.

As for Xu Rui...

A life assistant, a bodyguard, a person who collects intelligence, and a person similar to a housekeeper in the future. This is Yu Hua's new position for Xu Rui. Due to his growing speed, Xu Rui's original position as a scientific research assistant has been abandoned by him. Rui couldn't keep up with him.

Of course, if Xu Rui is willing to join the army to fight the Japanese invaders, he will not stop him.

In addition to family matters, Master can't be sloppy. If he is going to make a trip, Professor Zhao's assistant job has to be resigned.

Basically these things, but not much.

Back at the Nuclear Physics Laboratory, Yu Hua entered the door and was about to go upstairs when Zhao Zhongyao suddenly appeared.

"You kid, I looked for you everywhere, but I didn't see anyone in the cafeteria." Zhao Zhongyao, who was looking for someone after seeing Yu Hua, breathed a sigh of relief and said quickly.

"Uh...Professor, I went to the library to look up materials." Seeing this, Yu Hua scratched his head and responded, "Is there something wrong?"

"Professor Hua asked me to tell you that the school will soon issue an urgent notice. The exam for public-funded students studying in the United States in August will be postponed and will be postponed to November. The location is not Nanjing, but Changsha." Zhao Zhongyao has a serious face and eyes. Looking at Yu Hua, he announced the latest news.

Changsha in November.

"Thank you, Professor." Yu Hua was moved when he heard these words, and quickly thanked him.

"Thank you, and I have some gossip. The school is going to move to Changsha. This time, the school will be relocated to Peking University and Nankai University." Zhao Zhongyao's voice was lowered and his voice was extremely solemn.

Three schools moved south.

The historical Changsha Temporary University, the predecessor of the Southwest Associated University, has come.

"Moving south?" Yu Hua understood that Zhao Zhongyao's gossip was by no means aimless. The Southwest Associated University in history came from the three schools in the north and south of the Qing Dynasty that moved south to Changsha and constituted the temporary university in Changsha, but the time was slightly earlier.

It is understandable that the time point is advanced. After all, he, the butterfly, deciphered the red secret, and it is not unusual for Nanjing to make the decision to move the three schools southward earlier.

"Don't spread the word after listening to it, so as not to cause adverse effects. The news of the southward move should appear soon." Professor Zhao Zhongyao reminded.

"Student understands, professor, there is something the student wants to say..." Yu Hua nodded to take note, looked at Zhao Zhongyao with a firm face, and said softly.

Hearing this, Zhao Zhongyao wondered, "What's the matter?"

"The student may be leaving, so I can't be your assistant." Yu Hua bowed and saluted, and bluntly revealed his thoughts.

The words are sincere and there is no deception. Yu Hua can't do such a thing without saying goodbye.

"Ready to leave?" Zhao Zhongyao was stunned when he heard the words. Looking at Yu Hua, who was showing courtesy everywhere, he opened his mouth and wanted to say something to save him, but the words reached his throat but he couldn't make a sound.

There was a brief silence at the entrance of the stairs.

There is no lasting feast in the world, Zhao Zhongyao is very clear that such a day will come, because Yu Hua's talent is there, as long as he is advancing, then there will be a day when the young eagle will spread its wings.

respectively as expected.

However, Zhao Zhongyao did not expect to come so early.

Zhao Zhongyao did not ask Yu Hua what he was going to do, nor what Yu Hua was going to do. He stared at Yu Hua and said with concern as a husband, "Have you made up your mind?"

Yu Hua nodded earnestly: "The experience of studying and living with you during this period is very pleasant. Thank you, Professor, for letting me feel the charm and world of nuclear physics. If there is a chance in the future, I will definitely study nuclear physics with you. I believe that you mentioned the idea of ​​nuclear energy weapons and antimatter weapons, which is also the nuclear physics direction that students have been preparing to study."

"Okay! By the way, wait a moment." Zhao Zhongyao took a deep breath and nodded.

After he finished speaking, he turned around and went to his office.

Yu Hua had to stay where he was. Soon, Professor Zhao Zhongyao came out of the office again with a pale yellow letter in his hand.

"This letter was originally intended for you before you went to America, but I think it's better to give it to you now, take this letter, go to California, go to Caltech, go to Robert Andrew Millikan, he will I'll give you a chance." Zhao Zhongyao came to Yu Hua, glanced at the already written recommendation letter in his hand, smiled, and put it in front of Yu Hua.

This letter of recommendation, he wrote a long time ago.

"Students thank their teachers for their kindness." Yu Hua was moved, took the letter of recommendation from a Nobel-level top physicist, and gave him a salute to express his gratitude.

"I'm waiting for you in the field of nuclear energy weapon research. Go ahead and leave me alone." Professor Zhao Zhongyao smiled and waved his hand. After saying a future goal, he turned and left.

student union. ——Yu Hua looked at the back of Professor Zhao Zhongyao leaving, and said silently.

Nuclear energy weapons, or atomic weapons for short, are one of the long-term goals, but not now.

Yu Hua carefully collected the recommendation letter and went upstairs.

There is no doubt that this letter of recommendation signed by Zhao Zhongyao is an epic item in the academic field.

As a student, Yu Hua is very aware of the value of this recommendation letter, which is no less than Professor Von Kamen's business card and Professor Solomon Lefschetz's postcard.

Zhao Zhongyao focuses on physics, Feng Kamen focuses on aerodynamics, Lefschetz focuses on pure number topology, three different fields, with the things given by the three bosses, Yu Hua can basically go to any school he wants to go to. School.

Also, don't forget the Cambridge behind your master.

Before I knew it, I seemed to have entered a world I had never imagined, a world I had to look up to.

"Keep going, Yu Hua..."

Yu Hua pondered for a while, then let out a breath, his eyes were clear and pure, with a touch of brilliance.

Outside the laboratory, the sky is blue and the sun is just right.
