Finding the right direction, Donner Shearer's trial production immediately increased the speed. More than 30 skilled workers cooperate with 2 engineers, the equipment of the factory is twice as much as that of individuals, and almost every worker is an all-rounder! The speed of trial production is satisfactory.

The issue of the bazooka was put on the agenda, and an engineer was directly recruited in person. One was Lyman Steinbeck, a German-American, almost 60 years old. After World War I, he left the Krupp factory in Germany and came to the United States, where he went to the Fischermann tank factory in the United States to work as an artillery engineer. Only one daughter married to Texas, and after the death of his wife, he was also disheartened and retired early, and the economic crisis almost wiped out the wealth he was preparing for retirement, and he had to go out to work again. Another reason for hiring him was that he knew about the Monroe effect, and although he hadn't studied the hollow energy effect in depth, he knew it after all!

The principle of the bazooka is not difficult, and he described it to Lyman Steinbeck in a few words. It is in a 1.5-inch or 2-inch seamless steel tube, using the principle of recoilless gun, the rocket end is pushed out, and a balance body about the same weight as the rocket is equipped at the rear end, and the rocket is ignited 5-10 meters away from the steel tube. In front of the rocket segment is a warhead, in the rear end with a tail, and in the middle is the rocket body. It is required that the balance body should be in a powder state when leaving the steel pipe to avoid destroying the people and objects behind; It was determined that the hollow shaped cover was made of copper, and the recoilless gun was made of nitroglycerin. It is required that the effective firing range is 300 meters, at 300 meters it is possible to break 30 mm of homogeneous armor steel plates, and the length of the steel pipe should preferably not exceed 1 meter.

Lyman Steinbeck praised the design concept of the bazooka! Enthusiasm for work is also stimulated! I have described it so clearly, I have done everything I know, but I didn't expect that the development is still difficult. From the relationship between the dosage of nitroglycerin and the weight of the rocket, the determination of the muzzle velocity of the rocket, the material of the balance body, the fixed tail and the open tail, and the size and angle of the shaped energy cover, .......

Lehmann Steinbeck can be described as a motivated, careful and rigorous method. It's just that I think the dollar is thrown into it for 11,000.

The most popular among Americans are semi-automatic rifles that shoot 9×19mm pistol rounds, and factories have begun to produce them in small batches, all of which are gift-grade. It became the first gun for a wealthy kid in the United States, and according to Woody, it also attracted the love and attention of the police and the gangsters.

James Catlett's bullet was finalized first, and a patent application was also filed. Two tasks were assigned directly to him, one was to assist in the transformation of the bullet production line, and the other was to study the armor-piercing bullet of the 12.7×99 mm ammunition of the Browning large-caliber heavy machine gun bullet.

Donnell Shearer's research also went much smoother, and it took two months to come up with a sample that was basically finalized. The 2000 rounds of ammunition were tested without malfunction and weighed half a kilogram less than the Garand. Applying for a patent? No! At present, it only handles corporate trade secrets. Added an empty gun hang-up mechanism. Design a wooden butt and 20-round magazine suitable for the Chinese. Give him the automatic trigger and trigger drawings, develop a drum with a heavy barrel and 50 rounds, and design a machine gun for the squad. Donner Shearer gave the parameters of the 7.62×39mm bullet and shortened the magazine to develop an assault rifle.

Aunt Liu's research has finally made a breakthrough and has synthesized sulfonamides in the laboratory, but it will take time to form industrial production. There are already 10 tons of reserves imported from Germany one after another, and there is no need to worry about the Germans getting stuck. In just 3 months, the drug has brought more than 3 million profits, and even Isaac lamented that he can make money faster than him.

ushered in 34 years of Christmas. Arrange for security guards to rotate on duty and take a holiday! Each person is given a month's job, the family situation is counted, and each child is given a Christmas gift! Take the homeless Lyman Steinbeck back to the estate for the holidays. Encouraged Smith to go back to his wife and children, give him a few more days off, and told him to bring it back if he could, because there was a place to live here anyway.

Xiaoya has returned to the manor for the first time since she lived in the school to study, and it seems that it is not easy at school! Even the old people have said, 'Learning is not an easy thing'. The elated Xiaoya hugged one by one, except for me, of course, it seemed that she was angry! Angry? Easy to do!

"Xiaoya, Tiedan, let's go shopping, do you want to go?" Immediately solve the problem, Xiaoya ran over and hugged her and didn't let go, complaining why she didn't go to see her! Calling out to Dawu and two young bodyguards who don't want to go home on vacation, one named George Nader and the other named Ralph Eastman.

The New York City government has put a lot of effort into setting off the festive atmosphere, adding national flags and buntings, and the streets are cleaner. Especially in the commercial area, businesses are hanging Christmas signs everywhere, street performances, and selling flowers are even more. Xiaoya and Tie Dan's change was still needed, so they had to take them to the bank to withdraw the change.

If you're hungry and want to eat Chinese food, no problem, go to Chinatown! Chinatown doesn't seem to be much affected by the economic crisis! Everywhere is booming. Xiaoya chose a Huaiyang restaurant, the store is not small, but there are not many customers. It seems that Chinese still don't give much face to Christmas, and still like family reunions during the holidays. The taste is good, and it looks much finer than the northern dishes. Ordered to send two tables to the manor, one table to the factory security, and ask for the addresses of the two American bodyguards. Everyone's happy! The happiest is still the boss.

Eat and drink to your heart's content, hum a minor tune and leave! The bodyguard asked, sir, are you singing a Chinese tune? What? Haven't you heard? I remember that when I was tutoring my daughter's primary school English in my previous life, I learned it from the English song tape sold by my daughter's school, and it was also my favorite English song. Isn't this time there yet? The damn tape is not clearly introduced either.

"Brother, it's nice, teach me!"

How can my sister's little request be refused?

"Well, listen, I forgot where in the United States I listened.

If you missed my train,

You should know that I am gone.

You can hear the whistle coming from a hundred miles away,

A hundred miles, a hundred miles,

……

You should know that I am gone,

You can hear the whistle coming from a hundred miles away. (A tribute to Heidi West Hedwig G.)

Festivals are short-lived, and happiness can never be extended; Xiaoya still walked away in tears, so I didn't dare to look at her tears, afraid that I would be soft-hearted and drag her back!

James Catlett took out a variety of Browning 0.50-inch machine gun rounds, all of which were produced by Winchester in New Haven, Connecticut.

said: "Mr. Li, the current armor-piercing deflagration bomb can penetrate a 15mm thick steel plate at a 30° impact angle at 830m, and a 20mm thick steel plate at 125m. Without new design concepts, it would be difficult for us to surpass these mature products. ”

After reading the drawings, I felt a little hesitant; The current armor-piercing deflagration shells cannot guarantee that one shot will penetrate Japanese tanks, mainly because the landing angle is too small, and the armor-piercing ability of large angles is greatly reduced. Is it necessary to study tungsten alloy shelling armor-piercing bullets now? The structure is complex, the processing accuracy is high, and it is too expensive! You should choose a simple transverse effect enhanced bomb to give it a try, which is also something invented by the Germans.

"Mr. James, give this structure a try."

As I drew it, I said: "The warhead mainly consists of four parts, the hood, the projectile body, the cartridge belt and the plastic loading core. The hood is made of aluminum or copper; The projectile body is made of two materials of different densities, the outer part of the projectile body is a high-density material, such as steel or tungsten, and the core is composed of a low-density material, such as pure aluminum or plastic. Available in both full-bore and sub-bore copper designs and scaled proportionally. How the bottom is sealed or closed at the head is the key question. This structure can also be applied to large-diameter shells, which is currently kept secret, regardless of the results of the tests. ”

"Yes, sir!"

"Mr. James, you are to begin working on grenade fuses, pressure and pull fuses for mines, and mortar fuses. If there are no patent restrictions, we can use mature designs directly. ”
