Chapter 1852 Can't Take You Away

    In this era, aviation and aerospace have not yet separated.  Of course, there may be many people who don't even know the difference between aviation and aerospace.  Simply put, one is inside the atmosphere and the other is outside the atmosphere.  Airplanes belong to the field of aviation, and rockets belong to the field of aerospace.  Although the space shuttle is called an airplane, because it flies out of the atmosphere, it is still in the field of aerospace.

    Because there is no special distinction between aviation and aerospace, a large number of aerospace experts are still aviation professionals.

    The technician in front of me, since his teacher is von Karman, of course he is on the path of aerospace.  As for what is so great about this teacher, just look at his name.  In the professional field, the dividing line between aviation and aerospace, that is, the height of 100 kilometers on the earth's surface, is called the Karman line.

    Now I heard Qin Baoshan's question.  Mr. Qian in front of him was very strange.  How did this person understand himself so deeply?

    "Yes, I am very interested in rockets, but it will take many years of development to push the rocket to the point of use." Mr. Qian said.

    Speaking of rockets, it goes without saying that the earliest ancient Chinese rockets were used.  Needless to say, the ideal of Wanhu Feitian.  In modern times, the founder of the rocket industry should be the Russian Konstantin Tsiolkovsky.  He has a very famous saying, "The earth is the cradle of mankind, but mankind cannot be bound in the cradle forever."

    He is a hearing-impaired person who has not studied systematically, but he has used his own power to promote the progress of the rocket industry. He has written more than 730 treatises in his life, and was the first to propose the concept of liquid rocket propellant and multi-stage rocket.  He also deduced the formula for calculating the speed increase obtained by the rocket during the operation of the engine under ideal conditions without considering the aerodynamic force and the earth's gravity, which is the theoretical basis for the rocket to fly in space.  This famous expert died in the 1930s, and others took up his baton and moved on.

    In the United States, there are also flying idealists. Among them, the most famous is Robert Huggins Goddard. He loves to study rockets.  Propellant for solid rockets.  After that, he has been doing this business all his life.

    After he successively tried many kinds of solid rocket motors and studied the properties of various fuels with mathematical methods, he came to an important conclusion: "To make the rocket reach the speed required for space travel, liquid hydrogen and liquid oxygen must be used.  The main liquid rocket engine."

    Of course, it is too difficult to do this kind of thing.  After several failures, Goddard successfully conducted the first liquid propellant rocket launch experiment on March 16, 1926, at the Ward Farm outside of Aubarn, Massachusetts.

    However, the rocket at that time was still very crude, and it was still a long way from a real rocket.  On the other side of the ocean, Germany also has a famous scientist Braun.  He built rockets in the modern sense, most famously the V-2 missile.  It can be said that ballistic missiles all over the world started from this German missile.  After the end of World War II, the United States obtained Braun himself, and the Soviet Union obtained a large amount of materials.  So rocket experts in the United States and the Soviet Union continued to develop on the basis of this rocket, and finally established a modern aerospace industry.  When Goddard wanted to fly to the moon with a rocket, everyone thought he was dreaming.  Little did anyone know that, decades later, this dream would come true.

    Now, Mr. Qian in front of him also has the dream of a rocket, but at the same time he also knows that this dream is probably very far away.

    Hearing his words, Qin Baoshan shook his head: "No, this dream is not far away. Maybe we will see this new type of weapon soon."

    Qin Baoshan's words made Mr. Qian stunned again: "Rockets are used to detect the sky. Why is it a weapon? And, we will see it soon?"

    "Rockets can be used as a substitute for cannons. Super cannons can shoot shells tens of kilometers away. Rockets can shoot shells hundreds of kilometers, or even thousands of kilometers. The emergence of rockets is for military services. We have already  There is a history of solid rockets, and they were used in the military at that time."

    There are some things that Qin Baoshan can't say. By 1944, Germany's V-2 missiles were mature, and a large number of missiles flew to the UK, causing great panic to the UK.

    After Qin Baoshan finished speaking, he sighed: "Mr. Qian, I'm sorry, but I can't take you back. You need to stay here. I'll go back when the time is right."

    Qin Baoshan knew that Qian Xian in front of him was of course an important technician, and if he went back, he would definitely be able to promote the development of the Eighth Route Army's military technology.  butIt was Qin Baoshan who couldn't do this, and it would be more important for Mr. Qian to stay here.  In the final analysis, it was because the conditions of the Eighth Route Army were too backward to provide Mr. Qian with a sufficient scientific research platform.  In other words, if he went to the Eighth Route Army, Mr. Qian would not be able to continue his scientific research projects.  Then China will lose an important scientist.  Although it is said that excellent personnel will show their full potential no matter what field they are in, Qin Baoshan does not want to rewrite history because of himself.

    "But please rest assured. In the future, at the right time, the motherland will definitely take you back. At that time, you may be able to take the scientific research personnel of the motherland to launch our Chinese rocket into space. We used to be a  In an ancient cultural country with a long history, we once had a dream of flying into the sky. Mr. Qian, this dream is pinned on you."

    At this time, Mr. Qian was very strange. He didn't know why Qin Baoshan said such words.  But he also knew that Qin Baoshan rejected him too.

    After thinking for a while, Mr. Qian said, "Do you think rocket technology will be realized soon?"

    Qin Baoshan nodded: "Yes, the military is always the final stage of science and technology."

    Who said this sentence?  Qin Baoshan thought about it in his mind, it seems to be a sentence in the Three-Body Problem, Qin Baoshan is also a Three-Body Problem fan.  Even if he was in another world, he would carry this book with him when he went to the Imperial Cemetery to do military writing.

    The fact is that, during the Second World War, science and technology have developed greatly, and this development is equivalent to a normal hundred years.

    Hearing Qin Baoshan's words, Mr. Qian finally nodded: "Then I will wait here. If rocket technology will develop rapidly, then what kind of engine do you think is the most suitable?"

    "Unsymmetrical dimethylhydrazine and nitric acid." Qin Baoshan blurted out.  (Remember the site URL: www.hlnovel.com
