Chapter 1002 Test

Previous page        Return to Catalog        Next page

    The propeller is a curved surface with a special shape. It can indeed obey certain mathematical equations, but it needs to be decomposed into sections of arcs, and each section follows a mathematical equation. As a whole, it is extremely complicated. Therefore,  If you want to use formulas to make propellers, it is quite complicated. In later generations, you will need to use advanced multi-axis linkage CNC machine tools to ensure machining accuracy.

    However, it is easy to follow the cat and draw the tiger. No matter what mathematical laws you have, or how you bend, I will do it. In the hands of the master, the propeller with the same shape and curvature was quickly created.

    "Generally speaking, the materials needed to make propellers are hard and strong, and beech wood is used more often. However, we don't have beech wood here, so we use the best jujube wood, and we don't have to keep using it. If we only fly this time, we should  There will be no problem." Qin Baoshan said to Major Cromlin at the side.

    It was originally promised a week, but in fact it only took four days. The master craftsmen have already made the exact same propeller day and night. Compared with the original one, there is almost no difference.

    At this time, Liu Tiezhu, an old carpenter, was holding a fine sandpaper and polishing the surface of the propeller to make it look smoother. His big rough hand touched the surface of the propeller, and it seemed that by touching it, he knew where it was qualified.  , what is not qualified.

    Major Cromlin replied there: "Yes, this propeller looks fine on the outside, but we need to try it to know how it is. We need to install it and test it."

    The biggest problem is balance. The propeller rotates at high speed. If it is unbalanced, it will shake non-stop, and the vibration will be transmitted to the engine and the fuselage. Not only will it make passengers uncomfortable, but it will cause mechanical fatigue.  It may even cause the plane to crash.

    Therefore, it must be tested.

    "That's right, we need to test it, not only on the spot, but in my opinion, it's better to fly it up, fly it around the sky, and determine how the power is. After all, when we return, we have so many  Senior official, if there is an accident, it will be bad." Qin Baoshan said.

    What's the point of testing only on the ground, and you have to go to the sky for a circle, that's cool.

    Qin Baoshan said so, looking at Major Cromlin with expectant eyes, and at this moment, Major Cromlin was a little embarrassed: "Yes, we need to test it in the sky, it is the best, but what can you provide?  Is there enough gas?"

    Today's aircraft engines are all piston-type and use gasoline, which is no different from the gasoline used in cars. But even so, gasoline is quite rare for the Eighth Route Army. Will they provide enough gasoline for their side?

    Major Cromlin was a little worried.

    "Of course this is no problem. We have already made preparations for you. We have won several battles on the front line and captured a batch of gasoline from the devils. It has been shipped over and is enough for you to use." Qin Baoshan said.

    Where did the gasoline for the Eighth Route Army come from?  Lao Jiang refused to provide it, so he could only seize it on the front line.

    After getting this promise, Major Cromlin was very happy: "Okay, if there is enough gasoline, then we will test it in the sky!"

    "Well, Major Cromlin, can I go up with you?" Qin Baoshan asked eagerly, like a country bumpkin who has never seen the world, begging others to take him to gain knowledge, watching  Major Kromlin did not refuse Qin Baoshan's appearance: "Of course there is no problem with this, the cabin at the back is very spacious."

    "Can I sit in the front?" Qin Baoshan asked again.

    Major Cromlin didn't agree this time, he shook his head: "This won't work, there are a lot of buttons on it, if you accidentally touch any switch, for example, you turn off the engine, then we have to go together  See God."

    Well, I won¡¯t go to the front if I¡¯m not allowed to. In the previous few flights, I was a pilot, but this time I¡¯m a passenger, enjoying the God¡¯s treatment that only customers have. Unfortunately, I don¡¯t have a beautiful stewardess.

    "Playing the piano randomly, Comrade Qin Baoshan, you are playing the piano randomly!" After hearing this, Lao Liu was very unhappy: "Do you know how important you are? You are a rare and precious talent in our Eighth Route Army.  , how can you go to heaven? What if something unexpected happens?"

    Facing the angry old Liu, Qin Baoshan's tone was steady: "Old Liu, we filled the American planes with the fuel we refined ourselves. We have confidence in our own fuel, and there will be no accidents.  Americans dare to fly, so why don¡¯t I dare to sit, besides, it¡¯s not easy for Americans to come here once, how close we have to be to them?They communicate and fly around the sky together, which can shorten the distance between each other. What if the Americans support us with a few planes? In this case, our air force will be established. The little devil is on our heads all day long  Shang Saye, how we wish we could have our own fighter plane. Now there is only one plane, which is not enough at all. This is a good opportunity.  "

    Hearing Qin Baoshan's words, Lao Liu was still dissatisfied: "Huh, don't dream, how can the Americans be so kind, it would be nice if they could support us with some light weapons, planes, don't even think about it, in short, you want  God, that won't work."

    "Okay, eat people's mouths are soft, and others are short-handed. We have occupied your anti-big territory, so we have to obey your orders. If you say no, then I will not go. I told the Americans to go. Our gasoline  If I fail, I dare not go to heaven, you guys, figure out a way for yourself." Qin Baoshan said.

    When he said this, Lao Liu was speechless immediately: "Well, how can this work?" If this delays the schedule of the Americans, it will leave a bad impression on them.  Implement it as soon as possible, these Americans can only continue if they go back.

    "Yeah, you also know that this can't be done. Am I doing this for work? Don't worry, I will carry a parachute. If something happens, I will jump from the sky. I must be alive and well, and I will be fine.  Bar?"

    Lao Liu was not Qin Baoshan's direct superior in the first place, and had no right to order Qin Baoshan anything. He just came here to express his dissatisfaction out of love. Now that Qin Baoshan said this, Lao Liu has nothing to do.

    "Are you sure everything is safe?" Old Liu asked.

    "Of course, everything will be safe." Qin Baoshan said: "I have been working for several years, and I have always been safe. Don't worry." (Remember the website website: www.hlnovel.com
