After everyone left, Chongzhen and Wang Chengen were left in the conference room. Chongzhen laughed endlessly, which made Wang Chengen inexplicably. He asked:

"My emperor, what's so funny?"

Chongzhen looked at Wang Chengen and said in surprise:

"Don't you find it funny! This plan to exchange for Luzon in Sichuan is really a bit like this! Haha! A month later, when Zhang Xianzhong was taking a boat to pass by Nanjing, I was wondering whether we should meet this famous Zhang Xianzhong and see what he looks like."

Wang Chengen was a little surprised and asked:

"My emperor, you shouldn't have to sign Zhang Xianzhong! This is something that only fans of star-chasing fans in the future will do! What? Are you going to disguise yourself as a private meeting with Zhang Xianzhong? Or do you publicly summon Lao Zhang? Zhang Xianzhong is a loach, but he won't agree to see you. Okay, if you have time, do something else! If the emperor is free, how about our electrical team helper?"

During this period, Wang Chengen was stuck in the electrical unit every day. The motor of the seized submersible was removed and was treated as a teaching model by Wang Chengen. He patiently explained the principles and structures with the people in the electrical unit, and then officially began to test the generator. The first alternator and the first DC generator have almost been made, and the test can be carried out in two days. So Wang Chengen is squeezing time to attend the Military Affairs Office meeting. If Chongzhen hadn't asked him to stay, he would have gone to get his generator long ago.

When Chongzhen saw that Wang Chengen was devoted to the great cause of electrification, he thought that the steam engine had not yet been planned, but it was good to start with hydropower, so he expressed his opinion:

"In my opinion, the pace of electrification is slower, but the steam engine must be made immediately. I was also wondering when my armored vehicle will be equipped with a power unit! Otherwise, let the princess help you focus on the electrical unit, and you should focus on the steam engine project and concentrate on making the steam engine out. As for me, although one armored vehicle was made, there are still many places to be improved. I also plan to test-making tanks. Do you think there is a chance to build a tank in this condition?"

Chongzhen also knew that it would be of little help to let the princess who studied medicine get a generator. The most important thing is that the princess has been focusing on finance recently, especially with Sun Zhiwei. In addition to teaching at the Military Engineering Academy, she even stayed with Sun Zhiwei, and didn’t know whether to talk about business or private affairs. Of course, this matter cannot be concealed from Wang Chengen. Wang Chengen smiled and said:

"It would be nice for the princess to teach well. According to me, the princess might have to resist arranged marriages, and maybe she can stage a real free love drama of 'private lifelong'. Let's not disturb others' good things! As for the steam engine, there will be good news soon. My Emperor, don't worry! Besides, even if there is a steam engine, you can't install the steam engine on a tank, unless you want to build a three-headed monster tank that the Soviet Union once built. That guy is more than 15 meters long and probably can install the steam engine as power."

Chongzhen was encouraging about the frequent interactions between the princess and Sun Zhiwei. Sun Zhiwei's quick reception of new things is also a rare talent in this era who can keep pace with the times. If he is paired with the princess, it would be a good thing. Anyway, he has not gotten married to Zhou Shixian, and Zhou Shixian is also young and promising. If this arranged marriage fails, he is still afraid that Zhou Shixian will not be a bachelor for the rest of his life!

When he heard Wang Chengen talk about the three-headed monster tank, Chongzhen suddenly became interested and immediately asked about the "three-headed monster tank":

"You said the Soviets had made this three-headed monster tank, what was that thing? Why didn't I hear about it? Tell me about it."

Chongzhen, a military fan, only had two swords, and his understanding of Soviet tanks was only on t-34, t-80, etc., unlike Wang Chengen who was obsessed with the history of tank development in various countries. Wang Chengen thought to himself that if the emperor led a group of Ming Dynasty people to build tanks, would he also take the detours taken by tanks from various countries in the 20th century? He sighed and said:

"This Soviet tank has three turrets, the middle turret is equipped with a double-equipped cannon, and the last third turret is actually equipped with an eight-team Katyusha rocket launcher. Do you want to know what the turning radius of this big steel monster is? Please hear Stalin say: 'It doesn't need to turn, we can drive it directly to Berlin.', haha, Stalin has a really humorous sense!"

A tank is actually longer than a 40-foot container, and it is hard to imagine what kind of monster it is. Chongzhen’s ideal is to create a tracked tank. He didn’t even dare to think about the heavy tank. He smiled bitterly and said:

"Brother, if someone can create that perverted tank, it is because they have strong manufacturing capabilities! Alas! We don't have high requirements, so we just want to build a tank that is stronger than the Japanese 'bean tank' back then. You know, since the Jiashen armored vehicles can move, we think that building a tank is not a difficult task to reach the sky!"

Wang Chengen curled his lips, looking down on Chongzhen's ideals. Of course, this is mainly because he looks down on the Japanese "bean chariots". What kind of thing are they! He has to settle the positioning of the armored vehicles and tanks with the emperor, so that they don't take detours. Wang Chengen had to patiently discuss the tank with Chongzhen:

"I said, the Emperor, the Japanese 'bean chariot', that thing is good to deal with the Tartars and Li Zicheng's team. Its total weight is 3.45 tons, which is lighter than our Jiashen armored vehicle. The advantage is that it has good passability, but it can't even withstand a heavy machine gun bullet. If you use a cannon, it may destroy it as long as it is a high-explosive shell, so its ability to resist strikes is too poor. In my opinion, the Jiashen armored vehicle can refer to the standards of the 'bean chariot'. You might as well make the steel plate thinner, and the total weight should not exceed four tons, and it can deal with the Tartars and the Dashun Army. As for the tank, my suggestion should at least exceed the Japanese Type 89 medium tank, because the imaginary enemy of the tank is the Japanese, and at least it must be able to resist the Japanese rockets."

Chongzhen thought it was good. When dealing with the Tartars and the Dashun Army, the armor did not require 15 mm of steel plates at all, but to deal with the Japanese rockets, at least the front armor should be thicker. Chongzhen's understanding of tanks is the cognition in pictures and movies. In addition, he read some articles on the combat power of tanks, which is completely unrelated to building tanks. At the moment, he had to act modestly and ask Wang Chengen:

"Then, in your opinion, what standards should this tank be designed according to?"

Speaking of tanks, Wang Chengen's eyes lit up, thinking that if he could blow up the tanks, there would be endless topics, even if he could talk about them for seven days and seven nights, but everyone is busy, so let's talk about them for a long time! Just as he was about to say that, the eunuch Cheng Mangui came in to report at this time:

"Your Majesty, the 'China' football team and the 'Evergrande' football team are about to play. Isn't the emperor going to take the whistle in person? The time is over. Should the emperor go now?"

Speaking of which, after Chongzhen arrived in Nanjing, he spared no effort in developing football and especially liked to blow the whistle himself. Therefore, the Ming Dynasty's football was writing a new chapter based on the original Cuju. For example, the "China" team was named by China Vehicle Co., Ltd., and naturally the "Evergrande" team was named by Evergrande Real Estate. These two teams were held today's "Jashen Cup" final. Chongzhen originally wanted to take the whistle himself, but even if everyone opposed it, it could not stop the emperor's determination to be the referee. In the end, there was no way. He had to send heavy troops to the field to maintain order to ensure the emperor's safety.

But Chongzhen was talking about tanks with Wang Chengen at this moment. Although being a good football referee was his profession in his previous life, as an authentic angry young man, his interest in tanks was obviously overwhelming football at this moment. Chongzhen didn't care whether he broke the appointment. The discussion about tanks only started, so he couldn't interrupt it. He waved to Cheng Mangui and said:

"I have military and national affairs. I will pass on my oral orders. Let me ask Xiao Shunzi to blow the whistle!", and the eunuch Cheng Mangui ran away with one sentence. As for Xiao Shunzi's whistle blowing, this guy is used to listening to Chongzhen's whistle when playing football, at least he knows what offside means!

After sending the eunuch away, Chongzhen continued to talk about the topic of tanks:

"Let's continue talking about tanks, um, where did you just talk about it?"

"When it comes to what standards to design the tank."

"Yes! Tell me, what standards?" Chongzhen's eyes were shady about designing tanks. Of course, there must be a standard, otherwise he would have to cross the river by feeling the stones, and maybe he would have to touch the Year of the Ox and the Horse Month.

Wang Chengen followed his own thoughts and said:

"The Japanese bean tank has no reference value. Let's talk about the Japanese Type 89 medium tank first. The Type 89 tank was formally established in 1930. It uses nickel-chrome steel plates with surface carburized surfaces as armor. The front armor is 17 mm, the side rear armor is 15 mm, the top armor is 10 mm, the bottom armor is 5 mm, and the bottom armor is 5 mm, equipped with 57 mm short-barrel tank guns, and two machine guns. The four members are 12.7 tons in combat weight, 4.3 meters long, 2.15 meters wide, and 2.2 meters high. Our tanks must at least surpass Type 89. We have not yet refined nickel-chrome steel, so the steel plate must be thicker. As for the turret, you might as well learn from the overall cast turret design of the Soviet Union. As long as the weight does not exceed 18 tons, 1:8 bars are used

The rod coefficient, 1:40 reduction ratio, assuming that the lever length is one meter, two people pull the lever at the same time, each with a force of 50 kilograms, the total force of 100 kilograms, which is 980n, the torque applied to the crankshaft is 980n.m, and the torque output to the driving wheel is 39200n. Assuming the diameter of the driving wheel is 0.6 meters, the driving force can reach 11760n.m, that is, 1200 kilograms of driving force, and there should be no problem with driving. Of course, this tank will definitely not be fast, I am afraid it is slower than a cow, and there is no maneuverability at all." Wang Chengen took a piece of paper and calculated it for Chongzhen. It seems that manpower can indeed shake a tank of more than ten tons. If the two people's driving is really not strong enough, four can be added.

Chongzhen smiled bitterly, thinking that he didn't know what gear the tank could be in after starting, 1:20 or 1:10? The speed at the start was only 600 meters. If the gear was shifted, the speed would not exceed 1.2 kilometers per hour. If the gear was shifted, the speed would not exceed 1:20. If it could be in the gear at 1:10, the speed would be 2.3 kilometers per hour. Well, this is almost the same. Although it was slower than walking, it sacrificed mobility and had the ability to resist strikes. As the saying goes, there would be gains and losses, which is also worth it.

However, Chongzhen immediately thought of a question: Most of the bridges of this era cannot bear the weight of more than 10 tons, so he sat down dejectedly, sighed and said helplessly:

"I'm afraid that when we build an 18-ton tank, we won't be able to use it. I think it's difficult for this Ming bridge to pass by a 5-ton armored vehicle, let alone an 18-ton tank! I said, can we just build an amphibious tank so that we can't build it but not use it."

Chongzhen meant that the bridge could not pass, and our tanks would swim through the water. Of course, this was also a way. Wang Chengen was really moved by Chongzhen's persistence, but he felt that the design could not be made more and more complicated. He had to tell the emperor:

"My emperor, if the power is sufficient, it would not be a problem for tanks to pass through the bottom of the river. As for the big rivers, you can use cement ships to ferries. Of course, it is not impossible to build amphibious tanks, but it is better to be postponed. As for weight issues, you can also use additional armor to remove additional armor and install them when put into combat. This will reduce the full weight of the tank when the mule and horse is pulled. It is not impossible to reduce it to 12 tons when there is no additional armor. During World War II, the Germans did one thing, which was to paste cement on the tank. Although it was anti-magnetic armor, the purpose was to prevent magnetic grenades, but it could also improve the ability to resist strikes. Haha! Anyway, this is like the armor of the Ming Dynasty. In the era of cold weapons, it can protect people's bodies, and let the tank wear another layer of armor, which is called additional armor, which can also improve the tank's survival ability."

Speaking of tanks, Wang Chengen is really very talkative. Speaking of World War II, the Germans used bolts to install additional armor of 8 mm to 30 mm on the No. 3 light tank. After putting a layer of armor on the No. 3 tank, the effect was really good. It looked powerful and its protection ability also increased to a higher level. Although the No. 3 tank was equipped with additional armor less than 22 tons, it was tied with the 32 tons T-34.

Chongzhen couldn't help laughing. His grandmother's, the tank was originally a protective body, and he wanted to wear another layer of armor. Well! This idea is good! What's the modular design idea? Is this the reason? Chongzhen relaxed and smiled:

"I said Wang Chengen, you really have it. This idea is good! According to the modular design idea, we will design a light tank as the basic module to deal with the Tartars and Li Zicheng. The tank rushes forward nakedly and just use ordinary tank guns. If we deal with the Japanese, we will install additional armor and powerful tank guns. After transformation, it is a medium tank. What do you think?"

"The emperor is very proud! I think it's OK!"

Chongzhen was a sportsman in the past. I just heard Wang Chengen talk about the design standards for gas tanks, but after saying that, I still didn't know what to do. The armored vehicle is simple, just an iron shell and six wheels, but there is still no concept of tank tracks and rotating turrets. If you want to talk about tracks, you have seen many tracks of excavators, but you don't pay attention to them in normal times. Design and manufacturing are another matter. Chongzhen had no choice but to say:

"You have to design this track system, including load-bearing wheels and suspension systems. As for the turret, can you make a simple design? Haha, it's still a higher level. If we do it, we really can't do it."

Wang Chengen had no choice but to agree:

"In order to defeat the Japanese, I took over this design. The suspension system uses torsion rod suspension, and the load-bearing wheel adopts a t-34 design. As for the turret design, I have to think about it carefully. But I agreed, I'm too busy with the tank. You should catch Fang Yizhi's fault more!"
