    ten thousand years is too long, fight for now.  When they arrived at the Eighth Route Army Arsenal, these people who had returned from abroad immediately threw themselves into intense work.

    Now the scale of the arsenal in the Northeast is already very large, and the chimneys are almost undulating, constantly emitting black smoke. In one of the valleys, some rooms have been newly built, and these rooms have now become  The most secret military research unit of the Eighth Route Army.  It definitely belongs to the Tianzi No. 1 engineering unit of the Eighth Route Army at this time.

    There are the most stringent security measures outside. If someone who looks suspicious comes here and runs away immediately after being found, the patrolling sentry has the right to shoot and kill him directly.

    In the past few days, Qin Baoshan has stayed here. In fact, with Qin Baoshan's knowledge, he can't give these people much advice at all. However, Qin Baoshan came from another time and space after all, and he has all kinds of basic knowledge.  I still know something, so now, he can also tell everyone all this knowledge, so that everyone can avoid some detours.

    "I can't do anything about the specific design of the rocket engine." Qin Baoshan said to several experts at the scene: "I just know some of the design concepts, for example, the injected fuel can cool the side wall of the combustion chamber.  It is beneficial to increase the temperature that the combustion chamber can withstand. The key to this engine is the fuel pump, which needs to blow a large amount of fuel into the engine quickly. In this regard, we can start with the fire pump for fire fighting, and this fuel pump requires an additional gas generator.  Use this thing to generate high-temperature and high-pressure gas to drive the fuel pump to work."

    It is true that Qin Baoshan does not understand various details, but he is quite clear about the basic principles. Now as long as these principles are stated, the specific design will be handed over to these people.

    Of course, it is not enough to rely on the people in front of you. Soon, a large number of patriotic students will come here and participate in research together.

    The entire project is the most confidential, and it is a national strategic project.  Although it is said that it will consume a lot of resources, but with those gold reserves, it is still affordable.

    "Director Qin, what kind of fuel is suitable for this kind of rocket? We know that Germany uses liquid oxygen and alcohol. Do we also use these things?" Someone asked a question.

    "The rocket needs high-performance fuel. The Germans have no other way. They are seriously short of fuel, so they can only use alcohol to make up the number, which is unnecessary for us." Qin Baoshan said: "As far as the current situation is concerned,  The most suitable fuels should be unsymmetrical dimethylhydrazine and nitric acid. We can already produce a large amount of nitric acid in our arsenal. As long as we find a way to build a production plant for unsymmetrical dimethylhydrazine, we will be able to satisfy the production of fuel. And liquid oxygen  Compared with alcohol, these are fuels at room temperature, which is beneficial to us. Of course, the harmful aspect is that these things are either strongly corrosive or poisonous. So everyone must be careful when experimenting  .¡±

    For a long time, unsymmetrical dimethylhydrazine and nitric acid were the most important rocket fuels, even the Long March launch vehicle used these fuels.  It was not until decades later that there was a liquid oxygen kerosene engine.

    Now they have to solve the problem of availability, so it is definitely necessary to use these most convenient fuels, whether it is poisonous or not is not important.

    "Director Qin, we still have a problem." Another person said to Qin Baoshan: "Now our scientific research requires a lot of calculations. We can only rely on the abacus now, even if it is the calculations that have allocated hundreds of people to us."  The team is probably not enough."

    Qin Baoshan only talked about the principle, so he can speak freely and say whatever he wants, but in the hands of these people at the scene, they have to make precise calculations.  They have to calculate a large amount of data, and now they can only rely on the abacus, which is really unable to meet their needs.

    Qin Baoshan nodded, of course he knows that it is not enough to rely on abacus alone.

    "We will immediately organize personnel to go outside to purchase, and strive to purchase hand-cranked computers."

    Don't even think about such things as electronic computers. Even in the United States, there is only one computer system for deciphering telegrams. It is not a general-purpose computer, so if you want to do calculations, you can only use a computer by hand.

    China's first atomic bomb was calculated with a hand-cranked computer.  Qin Baoshan had considered this a long time ago. Under the current situation, they must purchase this kind of hand-cranked computer as soon as possible.

    After Qin Baoshan came out from this side, he immediately went to the other side to study mushroom bombs.  Who would have thought that these high-tech weapons started from the Eighth Route Army military factory here?  Qin Baoshan was extremely proud.

    ? When the day's work is over, Qin BaoShan left the factory area and just returned to the residence of the arsenal.  Li Yunlong's phone call came, and he excitedly talked to Qin Baoshan.

    "Brother Baoshan, you guessed right. The Yankees dropped the second nuclear bomb and destroyed another city of the little devil. This time, the little devil really wants to surrender, right?"

    In the past few days, Qin Baoshan has been staying here in the arsenal.  These projects are of great importance. Although it is still under the name of Arsenal, it is actually the largest scientific research institution in China.  Qin Baoshan did not dare to take it lightly. He should not only pay attention to the work and research here, but also pay attention to the lives of scientists here.  It is also necessary to avoid incidents of leaking secrets, and it is not at ease to hand it over to others.

    So he didn't go out, but Li Yunlong was paying attention to the little devil's movements. When he heard that the Americans flew to Nagasaki to grow mushrooms again, Li Yunlong was extremely excited, but he couldn't contact Qin Baoshan temporarily.  Finally got through the phone now.

    "Yes, Lao Li, just wait, the little devil is about to surrender, and our war of resistance against Japan is coming to an end."

    At this moment, Qin Baoshan felt very emotional in his heart. The War of Resistance Against Japan was about to end, and the military industry of the Eighth Route Army had also been established and was still in the process of flourishing.

    Putting down the phone, Qin Baoshan saw Wei Shuqin.  At this time, the other party's eyes were also full of excitement: "The war is finally coming to an end."

    For everyone, this is very exciting news.  After fighting for so many years, the little devil is finally about to be defeated.

    "So, shall we have a drink to celebrate?" Qin Baoshan asked his wife.

    "Of course," Wei Shuqin said, took out a bottle of wine from the table, and poured it into two glasses with a gurgle.

    "Let's celebrate together." (Remember the website URL: www.hlnovel.com
