Open an aircraft carrier to fight against Japan

Lin Yuan and Shen Wanqing returned to Beijing together.

Shen Wanqing asked suddenly: "I heard that Empress Dowager Cixi gave you a beautiful woman!"

Lin Yuan smiled and said, "How do you know?"

Shen Wanqing said: "The fire can't be contained in the paper, how could I not know, well, let's not talk about this, I want to repay the agency." After finishing speaking, she smiled at Lin Yuan and walked towards the newspaper office. go.

In this era, there are no street lights, only the dim moonlight. Lin Yuan quickly walked two steps to her side and said, "It's so late, I'll take you back."

Shen Wanqing thought for a while and said, "Where are you going? Let me see you off."

Lin Yuan smiled shyly. With her skills, she was the only one who could give her away, so she said to her, "I want to go to the China Railway Company to see how their railway design is going."

Shen Wanqing smiled and said: "Okay, let's go, I will tell you how to prevent being followed on the way."

The two came to the China Railway Company. Lin Yuan saw that the lights were still on in the building, and the door at the door had fallen asleep on the table. Lin Yuan entered the building and walked to Zhan Tianyou's office. In the rooms along the way, Some people leaned on the table, pressed the T-square on the drawing, set the set square, and compasses on the side, and drew on the drawing with a pencil in their hand; , constantly checking the data...

Lin Yuan came to Zhan Tianyou's office, and saw that Zhan Tianyou was giving lectures to the people in the room, it seemed that the lectures were almost over, and he was making the final conclusion: "Didn't we want to build a railway leading to the outside of the customs a long time ago? Now that the opportunity has come, all parts must go all out, who has any difficulties?"

At this time, a person stood up and said: "Master Zhan, after we bought rails, sleepers and other raw materials with funds, there is not much left, and we have to transport the workers to the outside of the customs, which is a lot of expenses... "

Zhan Tianyou said: "Those workers are doing manual work, can't they be recruited again outside the customs?"

The man said: "We are worried that we will not be able to recruit workers when we go outside the customs."

At this time, Lin Yuan interjected from outside the crowd: "It's okay! Don't worry, as long as you mention my name, you will definitely be able to recruit workers."

When everyone saw Lin Yuan coming, they stood up one after another. Zhan Tianyou waved everyone away. He walked up to Lin Yuan and asked, "It's so late, Mr. Lin doesn't rest, why are you here?"

Lin Yuan said: "Let's not talk about polite words, how is your railway design going?"

Zhan Tianyou said: "The styles of the roadbed, sleepers and rails all have precedents, so it is easier to design, and we are now designing the railway bridge."

Lin Yuan said, "Show me the bridge piers."

Zhan Tianyou brought a blueprint and said, "According to your lord's request, we have controlled the weight to about eight tons."

Lin Yuan took a look at the bridge pier, which was in the shape of a truncated cone. Lin Yuan estimated the position of its center of gravity according to its shape, then pointed to that position, and said, "Design an ear stand where things can be hung. .”

Zhan Tianyou asked: "What did you design that thing for?"

Lin Yuan smiled and said, "I want to ask the mountain god to move this thing. The ear stand for hanging things is for the mountain god to grab this pier."

Zhan Tianyou asked in surprise: "Aren't you joking? Mountain god, is there really a god in this world?"

Lin Yuan said: "Just do as I say, don't worry, I have studied the art of moving mountains, and I will definitely be able to move this bridge pier."

Zhan Tianyou looked at Lin Yuan suspiciously. He couldn't possibly know that what Lin Yuan wanted to do was to use the helicopter on the Beijing ship to lift the piers and place them on the Daling River!

It is not new to use helicopters to lift heavy objects for installation. In Lin Yuan's time, China had a precedent for helicopters to install electric towers in plateau uninhabited areas.

A day later, a helicopter transported several soldiers from the Beijing ship to Lin Yuan. On the warship, many equipment had to be hoisted up during replacement, so the hoisting operation was not difficult for them.

Two days later, according to Lin Yuan's request, the bridge piers were poured with concrete in a factory outside Tianjin. There were only two bridge piers in total. Only Lin Yuan and those soldiers were left at the bridge pier, and the rest were guarding around the factory.

A soldier lit a smoke bomb in the open space, and the orange-yellow smoke shot straight into the sky, which was extremely eye-catching. A helicopter soon appeared in their sight from the sky. It was a Z-25 on the Beijing ship. The reason why Lin Yuan asked Zhan Tianyou to keep the weight within ten tons was because the limit of the lifting weight of this kind of helicopter was ten tons.

Z-25 not only has the purpose of rescue, but also undertakes the task of cargo transportation, so a hoisting hook is installed on the fuselage. In order to reduce the impact of hoisting objects on the flight of the helicopter, the hoisting hook should be as close as possible to the center of gravity of the helicopter. The hoisting hook of the Z-25 It is installed under the main reducer, which is close to the center of gravity.

The main reducer is a very important part of the helicopter. The engine used by the helicopter is similar in principle to the engine of the fixed-wing aircraft. They are all gas turbines. The speed of the main shaft of the gas turbine is very high. Such a high speed is unbearable for the rotor, so it is necessary to use a speed reducer. The engine will reduce the speed.

The helicopter found the yellow smoke and flew towards it. Near the bridge pier, the hoisting steel cable was lowered. The ground personnel quickly fixed the steel cable on the ear platform of the bridge pier. After the inspection was correct, a soldier waved the signal flag, The hoisting is complete signaled.

He Di, the captain and pilot of the helicopter, saw this signal, and slowly pulled up the total pitch lever, which is a device used to control the helicopter's ascent and descent. With the pull up of the total pitch lever, the rotor blades moved upward Raised, the lift provided by the rotor increases, and the helicopter slowly rises.

When the helicopter rises to the predetermined height, He Di pulls the cyclic pitch change lever, and by manipulating the cyclic pitch change lever, the blades of the helicopter tilt forward, so that when the blades rotate, the helicopter provides thrust, and He Di pushes the cyclic pitch change lever again. With the left rudder, the helicopter turned a corner to the left and flew in the direction of the Daling River.

He Di stared at the color LCD in front of him, which displayed all flight-related information, such as atmospheric condition data, engine operation data, helicopter heading data, etc. He kept his eyes on the speed display area and scanned the LCD with his eyes from time to time. The mechanical instrument under the display checks the data on the two tables.Although the helicopter has achieved a fully digital cabin, some mechanical instruments are still reserved, just in case.

In order to ensure safety, it is absolutely forbidden to carry out hoisting operations under the condition of wind above grade 36. The wind speed of grade 36 is about [-] kilometers per hour, so He Di controls the cycle pitch lever and throttle lever to keep the speed at [-] kilometers per hour. hours or less.

After several hours of flying, he finally reached the ice surface of the Daling River. The time that tested him the most finally came.
