Chapter 1832: The model inside the dinner plate

    Qin Baoshan nodded. Sure enough, he had to give the other party some color, otherwise, he would only pay but not return. This is simply a hot face and a cold ass.

    Now that the other party has already made a promise, then Qin Baoshan is not stopping the other party's appetite, Qin Baoshan said: "The layout of the engine is very particular, after entering the jet age, it is very different from the propeller aircraft.  Take our bomber as an example, the engine can no longer be inserted on the wing, it needs to be hung under the wing. If one is not enough, two can be hung side by side.¡±

    The solution for the bomber is the simplest, just change the position of the engine. It used to be inserted in the center of the wing, but now it is hung under the wing.  In this way, the engine can be slightly farther away from the bomber's wing, so there is no need to worry about the impact of the engine's tail airflow on the wing.  At the same time, it is also the most convenient to change.  The entire aircraft does not need to be greatly modified, just change the engine.  As for why it is not above, of course it is for the convenience of ground maintenance.

    "If the thrust of the engine is not enough and you only want to use the jet engine, then you can combine two of them." Qin Baoshan said while cutting the sausage in the dinner plate into sections with a knife, and  to simulate the engine.  Then he cut bread slices into the shape of airplane wings and placed them on his dinner plate.

    This form is very suitable.  It has been used for many years, even in the time and space where Qin Baoshan was originally located, heavy bombers are also laid out in this way.

    But Qin Baoshan clearly felt that there was something wrong with the way these people looked at his model.  Just when Qin Baoshan had already set it up and was about to insert a slice of bread into his mouth with a fork.  Finally, one of the designers who had been silent all this time asked Qin Baoshan: "The model of your wing is not a straight wing, but a swept wing. Why did you design it like this?"

    In this era, almost all wings are straight.  This has almost become a custom, but when Qin Baoshan sliced ??bread with a knife, he was very skillful in cutting the shape of the wing into a swept-back shape.  After all, for Qin Baoshan, he is more familiar with this swept wing, and he must know that this thing is more in line with the shape of a jet's wing.

    Now that the other party said so, Qin Baoshan had nothing to hide.  He said: "The speed of the jet will be faster and faster, and it may even exceed the speed of sound. In this case, the straight wing will produce too much drag, and the only way to exceed it is to sweep the wing back."  Speed ??of sound."

    As for whether this is the reason, Qin Baoshan is not too sure, and now he is fooling around.

    Hearing Qin Baoshan's words, Cochran opened his mouth wide and said to Qin Baoshan, "This seems unlikely. No aircraft can break through the sound barrier. When approaching the speed of sound, the aircraft will hit the wall formed by the sound."  up, it would smash the craft into pieces."

    In this era, the speed of aircraft has become faster and faster, but no one can expect that the aircraft will exceed the speed of sound, because there will be a terrible thing in front of it, which is the sound barrier.  Many people think that the sound barrier is like a wall that smashes anything that tries to go beyond it.

    Hearing Cochrane's words, Qin Baoshan smiled: "Practice is the only criterion for testing the truth. Whether the sound barrier is a wall or not can only be known by trying it. To be honest, I want to be the first person to surpass the speed of sound.  alone."

    Qin Baoshan didn't say anything else, but he knew that since all the people present were aircraft designers, they all had ideals.  The sound barrier is an evil thing to say, and many people may be afraid, but as an excellent aircraft designer, it is to challenge the sound barrier.

    Since Mr. Wright has promised Qin Baoshan to give him all those things, then Qin Baoshan is unambiguous, and these basic common sense should be said.  In the eyes of this era, many things are simply insurmountable. In Qin Baoshan's eyes, they are simple and simple, and the sound barrier is one of them.

    Cochran stopped talking and became thoughtful.  The others were also contemplating, and while they were contemplating, Qin Baoshan had already put his bread wings into his mouth.  Then there are those sausage engines.  When there were only two left to eat, Qin Baoshan continued: "In the future, the engine technology will become more and more advanced. Then we may need only two engines to propel the aircraft that originally needed four or even eight engines."  At this time, in addition to hoisting the engine under the wing, you can also choose to fix the engine at the tail of the aircraft. Of course, at this time, the tail has to be changed to become a T-tail. The advantage of this layout is  In case one of the engines suddenly shuts down, it will not cause too much torque to induceEven if the aircraft yaws, the aircraft can continue to fly.  "

    If only two engines are hung under the wing, one on each side.  If one of them is turned off, the other will not only push the aircraft forward, but also turn the aircraft, and the steering torque will be very large.  Arranged at the tail of the aircraft, there will be no such disadvantage.

    Qin Baoshan continued: "When the war is over in the future, our current aircraft may become civil aviation airliners. The engines hung under the wings may cause a lot of noise in the cabin. If the arrangement  to the rear, then the impact will be less, at least the first class is at the front."

    This time eating, the harvest is also very big, Qin Baoshan murmured some things that are common in later generations.  But in the eyes of these people in front of them, they are all the freshest.  Qin Baoshan is a person who does not show himself, but has such profound attainments in this area, which is really admirable.

    In fact, after Qin Baoshan started to speak, the few people present stopped eating and kept thinking about Qin Baoshan's words.  Before he could think through all Qin Baoshan's thoughts, Qin Baoshan expressed a new idea, which opened their eyes.

    Now that Qin Baoshan had finally finished his meal, he stood up and said to everyone: "I'm full. Everyone, please do your own thing!"

    "Mr. Qin, please wait a moment." One of them said: "You are talking about the layout of the bomber. If it is a fighter, how should the jet engine be arranged?"

    There was anticipation in the eyes of the other party. Obviously, they hoped that Qin Baoshan could provide them with ideas.  (Remember the site URL: www.hlnovel.com
