    This is actually the same principle as the exhaust gas turbocharger for aircraft engines used at high altitudes.  It's just that the exhaust gas turbocharger uses the gas from the engine exhaust pipe to drive the turbine blades to rotate, and then drives another coaxial impeller to blow in air.  But now, what drives it to rotate has become a special high-temperature steam.  The other side becomes a super pump.

    Qin Baoshan's words gave Mr. Qian a sudden insight. During their research, the problem of the fuel pump had troubled them for a long time.  Now they have been trying to use the gas of the rocket engine to drive the turbo pump to rotate, which is very difficult to do.  Now that Qin Baoshan has given a new solution, it only needs to get a special power system, and he also pointed out the raw materials used.

    This surprised Mr. Qian very much.  And he can also imagine that this kind of plan really has a great possibility of being realized.

    At this time, Qin Baoshan had already said it anyway, not afraid of the other party's suspicion, at worst he would say that he was just thinking about it when he was bored, that he had a dream of flying, or something like that.

    "In addition to the turbo pump, another important aspect is the heat dissipation of the engine." Qin Baoshan continued.

    The rocket engine can eject high-temperature and high-pressure gas to propel the rocket forward.  These high-temperature and high-pressure gases are generated in rocket engines.  This means that this rocket engine needs to withstand very high temperatures.  In the current era, research on high-temperature materials is still very backward.  Rocket engines simply cannot handle much heat.

    Take the V-2 missile as an example. When ethanol and liquid oxygen burn violently in the engine combustion chamber, the flame temperature can reach more than 2,500 degrees.  Even steel would melt at this temperature.  So if you want to be able to manufacture qualified rocket engines, you must solve this heat resistance problem.

    "We know that a spherical shape is the most perfect shape, but the combustion chamber of a rocket engine is best made in the shape of a pear. This shape can have the smallest heating area. Of course, even this is impossible to meet the needs of a rocket engine.  .So in addition to solving the problem from the shape, we can also consider it from another angle, that is, to cool the rocket engine. We don't need to find extra coolant, we can use the fuel carried by the rocket itself. Specifically, we  After the fuel enters the engine, it is first injected onto the inner wall during combustion. In this way, part of the heat on the inner wall of the combustion chamber can be taken away, thereby reducing the ablation of the combustion chamber."

    These are the basic rocket engine principles, but for people of this era, it is still a kind of innovation.  Of course, Braun is already doing that.  So after he solved these problems, he successfully manufactured the rocket.  Except for Germany, other countries do not have this capability. They only started research after the war ended and they obtained German technology.

    At this time, Qin Baoshan explained all these technical principles.  What exactly will be used to cool the rocket engine is something Mr. Qian has to consider.  Qin Baoshan has opened a door for him.

    In the room, there was silence. Others watched the two people communicate quietly without saying anything. Among the people present, Chen Rui led the team.  But if you want to say that the technical strength is the strongest, it is definitely Mr. Qian.  He had heard that Qin Baoshan was very powerful, but he never expected that he would be able to solve technical problems for Mr. Qian.

    Time passed bit by bit like this, Mr. Qian didn't say anything more, he had already fallen into deep thinking, he was thinking about these things Qin Baoshan said, and how to apply them in practice.

    Just at this time, another voice finally spoke: "Those who engage in theory can't go with you, so can those of us who engage in production go with you?"

    When Mr. Qian was talking, they didn't interrupt.  Now Mr. Qian has been silent for a long time, and the atmosphere is a bit cold, and finally this person speaks.

    Hearing this person speak, Qin Baoshan looked over and looked at him.  I saw him of medium build, wearing a factory uniform, with sleeves on both arms.  At first glance, it looks like a front-line production worker.  His hands are also full of calluses.  The other party came in such a hurry that he didn't even have time to change his clothes.

    "Excuse me, what kind of production are you doing?" Qin Baoshan asked the other party.

    "I'm from Detroit. I'm an engine technician from Ford Motor Company. My name is Ma Sanbao." The other party said, "I, and a few of them, are all from Detroit."

    Hearing this, Qin Baoshan's eyes immediately brightened.  Detroit, the Motown!

    Detroit is located on the Detroit River in southeastern Michigan, across the river from Windsor, Ontario, Canada. You can see from the map that this is the Great Lakes area, and the waterway is very convenient.?So, Detroit gradually became a transportation hub.  The shipping, shipbuilding and manufacturing industries here are slowly rising.

    In 1896, Henry Ford built his first car in the workshop he rented on Mack Avenue.  In 1908, the Ford Model T was built, and the glory of Ford began.

    In addition to Ford, Detroit has other automotive pioneers, such as William Durant, John Francis Dodge and Horace Elgin Dodge brothers, Walter Chrysler and so on.  The names of these people are all familiar, and their subordinates are such famous cars as GM, Dodge, and Chrysler.

    So, in this case, Detroit is slowly becoming the auto industry capital of the world.  The development of Detroit's industry attracted a large number of residents from the southern United States. The population here grew rapidly and became the most famous big city in the country.

    In short, when people talk about Detroit, people will associate it with the Motor City. In this era, Detroit has indeed become the most famous Motor City in the world.  At this moment, Qin Baoshan's eyes lit up when he heard where these people came from.

    These people are indeed the most urgently needed talents in the military industry of the Eighth Route Army.  After all, some usual weapons have been produced so far.  Qin Baoshan is planning to trial-produce a batch of small engines.  These engines can be used on paragliders and motorcycles, allowing the Eighth Route Army to have higher mobility.

    This is just one of his attempts, and it hasn't developed yet.  After all, it is not so easy to produce your own engine.  Although Xiong Da and Lu Da are working hard, they are not in this profession after all.  Since these people in front of me came from the Motor City.  Then of course it will play a big role in these areas.

    So Qin Baoshan nodded immediately: "You are very welcome to join." (Remember the website website: www.hlnovel.com
