Chapter 285: Two Problems

Previous page        Return to Catalog        Next page

    Among these two problems, the first problem is relatively easy to solve. Based on the current industrial base of the United States, it is very easy to develop a Gatling cannon with external energy, but the second problem is not easy to solve.  .

    When the Americans were manufacturing the Vulcan cannon, they also first adopted the method of ammunition chains.  As a result, during the test, the bullet chain often broke, so it had to be improved later.  Since the chain is not enough, you have to use the drum.  The continuous supply of bullets is realized through the ingenious internal mechanism, and it is also given a very high name, called the bullet-free chain system.  Specifically, an Archimedes screw rod is installed in the drum, and the ammunition is arranged along the screw rod.  In this way, when the screw rotates, the ammunition is "squeezed" into the belt, similar to a meat grinder.  The ammunition belt is also specially made, just like a bullet holder. Moreover, after the bullets are fired, the shell casings are also brought back by the ammunition belt. In this way, the entire machine gun does not need to design a special ejection mechanism.  The shell finally returned to the drum.

    If you start this kind of thing from scratch, it will waste a lot of time and energy, but Qin Baoshan just knows the design schematic diagram of this bullet-free chain system, so you just need to move this design diagram.  Then the processing accuracy meets the requirements, so it should be able to make it.  .

    However, Qin Baoshan doesn't need to be too anxious. If he comes up and directly produces this kind of thing, it will make people feel a little too unbelievable.  So it can be said that Qin Baoshan has created many miracles, but no one can be omnipotent, and Qin Baoshan can't be too prominent.

    More importantly, if Qin Baoshan made three moves and five divisions, he would get this kind of thing out.  Then it will make people think that this kind of thing is very simple, especially now that he is doing it with him, and there are some Americans.  During the whole process, they may think that Qin Baoshan is awesome, or they may think that this thing is not difficult in the first place, Qin Baoshan does not want the latter.  Only by delaying for a longer time can they know that this kind of thing is difficult to make.

    It's like being a repairman, going to someone's house to fix something.  After negotiating the price of two hundred yuan, and then it was settled in a few clicks, then maybe this family should play a fool.  I feel that you can finish it in a few minutes, and it is not worth two hundred yuan at all, so you will renege on your bills. After a long time, the repairman will learn to be good.  The other party will feel that the repairman is not easy, feel ashamed, and give the money without hesitation.

    Moreover, Qin Baoshan still needs a lot of test sample cannons. If it can be made in a few strokes, perhaps the Americans will not need Qin Baoshan to test, and will directly produce them in their domestic factories.  Anyway, these things of Qin Baoshan have no intellectual property rights.  People in this era don't seem to pay much attention to this thing.

    At this time, hearing Qin Baoshan talk about these problems, Cochran also attached great importance to them.  She said to Qin Baoshan: "Then how can we solve the phenomenon that the bullet chain is easy to be torn?"

    "It is necessary to design a new ammunition supply method, but it is not easy to start from scratch. I need to try various solutions and finally find a suitable one. I also need a large number of shells for research."

    It is useless if there are only guns and no shells. Of course, the military factories of the Eighth Route Army can also produce 20mm shells.  But if you take this opportunity, you and the Americans want to come in large numbers.  Of course it couldn't be better.  The Americans have a strong industrial production, these shells are nothing at all.  For the Eighth Route Army, this has a great effect.

    Cochrane nodded vigorously: "Don't worry, just tell me what you need, and I will definitely coordinate it for you. Let us work together to develop this most suitable aviation weapon."

    Suddenly, Qin Baoshan thought of something, and said to Cochrane: "Isn't your mission to fly an aerial tanker? If you study these things with us during the day, how can you ensure enough air tankers at night?"  energy to carry out the mission?"

    Hearing Qin Baoshan's words, Cochrane said with a smile: "Now the personnel from the base of the Jinsui Army have come, and there are sufficient manpower. Even if I don't go to the sky, there are other redundant crews. During this time, I  I'm not feeling well, so I won't go up."

    Hearing what Cochran said, Qin Baoshan immediately asked, "What's wrong with your body?"

    Hearing Qin Baoshan's concern, Cochran immediately smiled like a flower, and said to Qin Baoshan: "Women, there are always a few days in a month that are uncomfortable."

    As soon as this sentence came out, Qin Baoshan suddenly felt a little embarrassed. In fact, he asked Cochran what was uncomfortable, just wanted to make sure: Cochran has been with him for a long time, has he also learned to talk nonsense?article?  Unexpectedly, people are really not feeling well.  And this kind of thing is embarrassing to inquire about.

    What Cochran said was very generous, and Qin Baoshan was embarrassed to hear it.  Seeing Qin Baoshan's appearance, Cochrane laughed again, very brightly.

    The development of the gun body of the rotary cannon is very smooth.  A week later, the first cannon was assembled.

    After hearing that the cannon here was assembled, Li Yunlong was very excited, and ran over to see what happened. When he saw this cannon, Li Yunlong immediately widened his eyes.  Although he had heard from Qin Baoshan a long time ago that this kind of set is equivalent to putting six cannons together, after all, he had never seen it with his own eyes, so he was still very curious. Looking at the cannon that appeared in front of him,  Li Yunlong said with emotion: "His grandma's, this thing looks cruel enough, six tubes."

    The six barrels are combined to form a thin and long cage shape. If you don't look at anything else, just look at these six barrels, and you know that this thing is definitely not easy to provoke.  If this is fired, how many shells can be poured.

    "Yes." Qin Baoshan said: "We have just started testing, and the speed is not too high. But it can reach 4,000 rounds per minute. If it can be stabilized in the future, it may reach up to 8,000 rounds per minute."

    What is this concept?  Czech-made light machine guns are the most commonly used weapons of the Eighth Route Army.  The standard rate of fire for this weapon is 500 rounds per minute.  Other machine guns of this era are basically of this order of magnitude.  The only exception is the German machine gun.  The German light machine gun has a rate of fire of thousands of rounds per minute, so even if it uses a belt to feed the ammunition.  If the machine gunner can't keep calm on the battlefield and keep his finger on the trigger, then the bullets in the chain box will be shot out in a short time.  As long as it hits the target, it is impossible to have only one bullet, and often two or three bullets all hit the body of a target.  Because the rate of fire is too high, the sound of the German light machine gun is like a chainsaw, and the performance is too terrifying. This kind of machine gun is called Hitler's chainsaw.  (Remember the site URL: www.hlnovel.com
