There are also a lot of information about tanks in the information that comes back from the head of the head. Pen, fun, pavilion www. biquge。 info But looking at those brain-opening designs, Qin Lang wordlessly threw them aside.

For the Citi tank, the most thought of it is the M3 Lee's "Seven Brothers' Coffin", the M4 Sherman's "Ronson Lighter", and the hateful German is more aptly named "British's Barbecue Machine". ”

"The Flagman is playing air superiority, and no one can compare to this!"

After a sigh, Qin Lang put the drawings back in the paper bag and put them away.

At this moment, Zhong Cheng shouted a report, and then walked in with a frown.

"Commander, the imitation of 20-mm anti-aircraft guns and 37-mm anti-aircraft guns has encountered many difficulties, and I hope to allocate another amount of money, this is my report."

Qin Lang looked at it carefully and asked:

"How's the 40mm hollow-charge grenade being studied?"

Zhong Cheng's face squeezed out a smile.

"That's not too difficult, the No. 1 product can penetrate a steel plate with a thickness of 20 mm and an inclination of 45 at a distance of 100 meters."

Qin Lang couldn't help but be overjoyed, and he asked urgently:

"Have you ever tried nickel-chromium steel, Gu Xin'an has already refined it!"

Nickel-chromium steel comes from materials obtained from steel mills, and after experiments, it was found that the hardness was good. After pressing it into thin steel plates, the special operations team had the first generation of bulletproof vests and new helmets, which was also a bonus.

Zhong Cheng showed an embarrassed expression.

"The grenade can penetrate it, but at a distance of 20 meters, the thickness of the armor is 10 mm, and the inclination is 90."

Qin Lang shook his head, this effect was really too bad.

"The development of anti-aircraft artillery and anti-aircraft artillery should still be stepped up. We don't have drawings for the Erley Air Defense Artillery, can we improve on which basis? The war defense artillery asked Citi's comrades to inquire about it, and if it didn't work, they would buy production patents. ”

The warlords of the Jin and Feng factions already had the existence of Erlikong 20mm anti-aircraft guns, and Qin Lang easily got one, and he also obtained the manufacturing drawings through surveying and mapping.

"Commander, although the Erlikong 20mm gun is lighter in weight and simple in structure, its shell must be brushed with oil frequently, otherwise it will be easy to get stuck. It is better to buy the patent of the Swiss Suroton ST-5, although the structure is complex, but the performance is much higher. ”

The Erikon 20 mm anti-aircraft gun is an enlarged machine gun, but its bolt structure is only suitable for small-caliber weapons, not for 20 mm caliber. Surotong does not have these problems at all, and it has another advantage: "high accuracy." ”

Qin Lang had also considered Su Luotong before, but it could only load a magazine of 20 rounds and run out at once, while Erlikong could use a magazine of 65 rounds.

"How much does a patent cost?"

I can't talk about money now, because the old foundation of Jicha Suihong District has been used, and if I put forward my purchase opinion, I'm afraid Luo Rong will be anxious.

Of course, he can't be blamed for this. It was already spring in March, and the melting snow had turned the capital into a swamp, and Soviet goods could not be transported at all. The global financial crisis has also led to a decline in Jinbo's trade volume. If it weren't for lipstick, soap, and cheap clothes, there would have been a famine.

Zhong Cheng glanced left and right.

"They offered $30,000, but they didn't bring production equipment, and they were in the British Concession in Tianjin. There are also drawings for the 37 battle defense guns, which are priced at fifty thousand dollars. ”

Qin Lang slapped his thigh suddenly,

"Let the head figure figure out how to get the drawings, if the opponent is well defended, forget it."

In a few months, Germany would help the Soviet Union produce 37-mm anti-aircraft guns. However, Qin Lang knew Comrade Steel's temperament, and if it wasn't for the critical moment, he would be reluctant to take it out!

And through Valina's relationship, she also has a few spy cameras in her hand, which should also come in handy at this time.

Zhong Chengleng paused for a moment and said:

"Commander, this is not good!"

Qin Lang said viciously:

"I really don't have any money on hand now, otherwise I wouldn't have made this decision. It's a big deal that I'll be able to order a batch of goods from them in the future. ”

Zhong Cheng pondered for a while.

"When the drawings come back, we immediately copy them and then improve them."

秦朗 says:

"I have two opinions about anti-aircraft machine guns. The first is fed by a chain, and the second can replace the barrel. The battle defense guns were made first, and I tried them on the chassis of the tractor. ”

I've thought about anti-tank guns before, but that's a bit of a chicken thing. As for the recoilless gun, Mao Zi studied it very deeply, but he took the wrong path and actually moved in the direction of air to ground. Qin Lang also thought about producing, but the price of that shell was too expensive. And there is also the problem of the manufacturing process, so I have to give up in the end.

After sending Zhong Cheng away, Qin Lang also went out.

Cheng Facai's diesel engine workshop has also been built, and Qin Langte approved some money for him to carry out on the basis of small diesel engines. After all, the machines produced by the workshop, the cultivated land is okay, and it will not be useful to fight a war.

"Tom, is there anything missing in the lab?"

Hearing Qin Lang's voice, Cheng Facai jumped up.

"Commander......."

Before coming to Huaxia, he didn't expect that the young man in front of him would have such great strength. Although it is still in tatters, he believes that in the near future, this will all change.

"We have a total of 15 people and we can develop diesel engines. Yesterday we looked at the diesel engine of Mercedes-Benz and found a high-pressure fuel injection pump, and it has to be said that the research of the Germans has come to the forefront of the world. We are now building on these results to manufacture new diesel engines. ”

At this time, Qin Lang can still catch a little tail in the material process. If it were a few years later, I'm afraid he would have to do nothing in vain.

Qin Lang smiled and said:

"First of all, I ask you to take care of your health, you are all talents that are lacking in Huaxia, and you can't have any mistakes. Another is the product, now Huaxia is a blank, my opinion is to slowly improve, and finally produce a large diesel engine. There is also the problem of talents, we also have a technical school, which has a lot of students, and I hope you can choose a few to be assistants. I explained this in advance, and if you don't like it, you can replace it at any time. ”

Cheng Facai nodded.

"It is true that we also need some assistants, our Chinese proficiency is indeed very poor, and we often make misunderstandings."

秦朗 says:

"Your family members have arrived in Zhangye, and I have already handed over the problem of children's education to the school, so I can go to class immediately. As for your relatives, you can tell me what arrangements you want. If it's within the allowable range, I'll definitely give it a pre-solution! ”

Cheng Facai heard this, and said with some excitement:

"In the past, we had a lot of white eyes in Citigroup, but today we are finally able to be people. Guys, thank you and repay Commander Qin with the results! ”

Qin Lang waved his hand.

"We are all Chinese, and now China is discriminated against in the world, and it is not that the country is backward. Since everyone has come together, we must break this situation and rebuild a strong China. ”

Cheng Facai and others also raised their hands and said:

"Yes, we must build a strong Huaxia!" (To be continued.) )
