Open an aircraft carrier to fight against Japan

The commander of the 32nd Division is Wang Rui, a helicopter pilot on the Beijing ship. When the Beijing ship returned to this era, it was he who drove the helicopter on the Beijing ship and launched torpedoes at the Japanese warship.

When Wang Rui received a call from Lin Yuan, he said, "Shuai Lin, we are ready and ready to dispatch at any time. May I ask what is the purpose of our operation?"

Lin Yuan said: "You have two purposes, the first is reconnaissance, and the second is to test the performance of the helicopter under actual combat conditions. I found that the Japanese army has some new weapons and equipment. You go to take some photos and come back. Take the photo and hit them casually to test the performance of the weapon system, understand?"

Wang Rui said: "Shuai Lin, if we let the Japanese army know that we have helicopters now, won't they be prepared in the future?"

Lin Yuan laughed loudly and said, "Comrade Wang Rui, what's wrong with you, why have you forgotten, we have used helicopters to beat up little devils many times, and they already knew about our helicopters."

Wang Rui smiled embarrassedly and said, "Shuai Lin, I understand, let's set off now." Wang Rui put down the phone and thought, "This is the first actual combat for our helicopter unit, so we must fight well," so Wang Rui Rui decided: to carry out this mission in person, helicopters are generally piloted by two people, so Wang Rui brought his old partner He Di to carry out this mission together.

Wang Rui took He Di with him to the hangar next to the airport, boarded the helicopter, and then the tractor pulled the helicopter out of the hangar and came to the airport. The so-called airport is just an open flat land, because the helicopter The requirements for take-off conditions are very low.

Wang Rui checked the various components in the helicopter, and everything was ready, and then turned on the starter motor. The helicopter uses a turboshaft engine. The core component of this engine is the Turbofan-1 aeroengine developed by Lin Yuan's experts. However, in order to be able to use it on a helicopter, the experts installed an output shaft on the turbofan-1, and use this shaft to drive the rotor, and the rotor can only rotate to make the helicopter fly.

The speed of turbofan-1 is very fast, a full 20 revolutions per minute. Such a high speed, the rotor cannot bear, because the rotor is [-] meters long, and the centrifugal force on the rotor is not small if it rotates a little. The speed is as high as [-] revolutions per minute, and the rotor will be directly shredded by its own centrifugal force, so the turbine shaft is connected to the rotor through a reducer.

When a turbofan engine starts to start, there must be something to drive the compressor and turbine to rotate first. The starter motor does this. The starter motor rotates rapidly, driving the compressor and turbine to rotate, and the rotor slowly follows. , Wang Rui opened the throttle control valve on the collective pitch lever, allowing the oil in the fuel tank to enter the combustion chamber for combustion under the action of the oil pump, generating high-temperature gas, which then drives the turbine, and the rotor gets faster and faster, and soon sends out "power Enough to take off" signal.

Wang Rui then said: "Get ready to take off," and then lifted the collective lever with his right hand to change the rotor angle, and the helicopter rose slowly. Helicopters are different from fixed-wing aircraft. In fixed-wing aircraft, the direction and height are changed by controlling These control surfaces are the tail and flaps. In rotary wing aircraft, the direction and height of the aircraft are changed by adjusting the rotor. The collective pitch rod is to adjust the rotor and control the helicopter's lift. device.

Wang Rui drove the helicopter slowly into the air, and when he reached the predetermined altitude, he manipulated the cycle change lever to change the direction and flew towards Yulangchuan. The armed helicopter is coming out, look at us now, we are driving an armed transport helicopter of this type, it is not good to think about it, "

Wang Rui smiled and said: "I understand the captain very well. The enemy's strength is not strong now. We don't need to make a dedicated armed helicopter. On the contrary, a multi-purpose transport helicopter is more practical."

He Di went on to say: "Then it would be good to equip our armed helicopters with radars. Look at our helicopters, there is no radar on them at all."

Wang Rui said with a smile: "What is the target of the helicopter's attack? It is mainly the enemy's tanks and vehicles. Such targets cannot be found by centimeter-wave radar. If you want to find them, you can only use millimeter-wave radar. But we don't have millimeter-wave radar at all now. , "

When He Di wanted to say more, Wang Rui smiled and said, "Don't say any more, we are going to Yulangchuan soon, you should pay attention to identifying the ground targets, prepare a high-definition camera, and start taking pictures when you find the Japanese army."

He Di said: "Well, I'll just identify it." Helicopters fly at relatively low altitudes, so pilots use their eyes to find and identify targets. He Di looked through the all-glass cockpit with a telescope Looking from a distance, the woods and fields on the ground receded slowly, and one after another mountain ridges also came and went back and forth in the field of vision. Not long after, He Di saw a long white band appear in the field of vision. He Di He took out the atlas, compared the position of the long belt with the surrounding mountains, and said, "The long white belt we saw should be the river called Yulangchuan."

Wang Rui said: "Shuai Lin said that the Japanese army is coming to the river, have you spotted the Japanese army?"

He Di raised his binoculars and said, "Not yet, shall we fly along the Yulang River to see if there are any traces of the Japanese army?"

Wang Rui nodded, turned the cycle pitch lever, the helicopter turned an angle in the sky, and flew eastward along the Yulang River. He Di held up the binoculars and searched anxiously for everything on the ground, such as houses that were smoking. Scattered pedestrians on the road came into view one by one, but there was no sign of the Japanese army.

He Di said: "It's strange, where did the Japanese army go, Lao Wang, please raise the helicopter higher, so that you can see farther."

Wang Rui said "OK" and then pulled the collective lever. In a helicopter, the collective lever and the throttle are connected together. When the collective lever is changed, the throttle will also change accordingly, which can help the helicopter achieve better results. When the helicopter rose to an altitude of 800 meters, He Di found a gray-white square in the telescope, and then said: "At ten o'clock, we found an object suspected of being a Japanese tank."

Wang Rui then steered the helicopter to fly towards ten o'clock. When it was not too long, He Di said, "Those gray and white squares are Japanese tanks. We found them."

Wang Rui said: "That's great, hurry up and take pictures, and when the pictures are finished, we will treat them well with rockets,"
