The commander of the 32nd Division was named Wang Rui, a helicopter pilot on the Beijing ship, and at the beginning of the Beijing ship's return to this era, he drove the helicopter on the Beijing ship to fire torpedoes at the Japanese warship.

Wang Rui received Lin Yuan's call and said, "Lin Shuai, we are ready, we can go out at any time!" What is the purpose of our operation? ”

Lin Yuan said: "You have two purposes, the first is reconnaissance, the second is to test the performance of the helicopter in actual combat conditions, I found that the Japanese army has some new weapons and equipment, you go to take some photos and come back, after taking the photos, you will beat them again, test the performance of the weapon system, understand?" ”

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

Lin Yuanha smiled and said, "Comrade Wang Rui, what's wrong with you?" How have you forgotten that we've beaten the little devils with helicopters many times, and they already knew that we had helicopters. ”

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

Wang Rui took He Di to the hangar on the edge of the airport, boarded the helicopter, and then the tractor towed the helicopter out of the hangar and came to the airport, the so-called airport is just an open flat land, that is because the helicopter has very low requirements for take-off conditions.

Wang Rui checked the various components in the helicopter, everything was ready, and then the starting motor was turned on, the helicopter used a turboshaft engine, the core component of this engine is the turbofan-1 aero engine developed by Lin Yuan's experts, but in order to be used in the helicopter, the experts installed an output shaft on the turbofan-1, and used this shaft to drive the rotor, and the rotor rotated to make the helicopter fly.

The speed of the turbofan-1 is very fast, there are 8,000 revolutions per minute, such a high speed, the rotor is unbearable, because the rotor is up to 20 meters, and the centrifugal force on the rotor is not small when it rotates slightly, if the speed is as high as 8,000 revolutions per minute, the rotor will be directly torn apart by its own centrifugal force, so the turbine shaft is connected to the rotor through a reducer.

When the turbofan engine starts at the beginning, there must be something to drive the compressor and turbine to rotate first, the starter motor is doing this, the starter motor rotates rapidly, driving the compressor and the turbine to rotate, and the rotor also slowly rotates, Wang Rui opens the throttle control valve on the total distance rod, so that the oil in the fuel tank enters the combustion chamber under the action of the oil pump to burn, producing high-temperature gas, and the high-temperature gas immediately pushes the turbine, and the rotor is getting faster and faster, and soon sends out a prompt signal of "enough power to take off".

Wang Rui then said: "Ready to take off!" Then lift the total distance lever with the right hand, change the rotor angle, the helicopter rises slowly, the helicopter is different from the fixed-wing aircraft, in the fixed-wing aircraft, the change of direction and height is completed by controlling the rudder surface, these control rudder surfaces are the tail and flaps, and in the rotary-wing aircraft, the change of the direction and height of the aircraft is done by adjusting the rotor, and the total distance rod is to adjust the rotor and control the helicopter lifting device.

Wang Rui drove the helicopter into the air slowly, and after reaching the predetermined altitude, he manipulated the periodic pitch lever to change direction and flew towards Yulang River. Look at us now, armed with a transport helicopter, it's not cool to think about it! ”

Wang Rui said with a smile: "I understand the captain very well, the enemy's strength is not strong now, we don't need to make a special type of armed helicopter, but a multi-purpose transport helicopter is more practical." ”

He Di continued: "Then it's good to equip our armed helicopters with radar, you look at our helicopters, there is no radar on them at all." ”

Wang Rui smiled: "What is the target of the helicopter's attack?" The main thing is the enemy's tanks and vehicles, such targets cannot be found by centimeter-wave radar at all, and if you want to find them, you can only use millimeter-wave radar, but we don't have millimeter-wave radar at all now! ”

He Di wanted to say more, Wang Rui smiled and said: "Don't say it again, you will soon arrive at Yulang River, you pay attention to identifying ground targets, prepare high-definition cameras, and start taking pictures when you find the Japanese army." ”

He Di said: "Okay, I'll just identify it." "The flight altitude of the helicopter is relatively low, so the pilot is to use visual vision to find and identify the target, He Di through the all-glass cockpit, holding a telescope to look into the distance, the woods and fields on the ground slowly retreat to the back, a mountain beam is also in the field of vision and walk back and forth, the time is not big, He Di saw a long white belt appear in the field of vision, He Di took out the atlas, compared the relative position of the long belt and the surrounding mountains, and then said:" The long white band we see is probably the river called Yulang River. ”

Wang Rui said: "Lin Shuai said that the Japanese army is about to reach the river, have you found the Japanese army?" ”

He Di raised the binoculars and said, "Not yet, should we fly along the Yulang River for a while to see if there is any trace of the Japanese army." ”

Wang Rui nodded, turned the periodic pitch pole, the helicopter turned an angle in the sky, and flew east along the Yulang River, He Di held the binoculars, anxiously searching everything on the ground, the smoking house, and the scattered pedestrians on the road came into view one by one, but there was no shadow of the Japanese army!

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

Wang Rui said "yes", and then pulled the total distance lever, in the helicopter, the total distance lever and the throttle are connected together, the total distance lever changes, the size of the throttle also changes, which can help the helicopter to obtain better flight performance, when the helicopter rises to an altitude of 800 meters, He Di found a gray-white square in the telescope, and then said: "At ten o'clock, an object suspected of being a Japanese tank was found. ”

Wang Rui then controlled the helicopter to fly in the direction of ten o'clock, and after a short time, He Di said: "Those gray and white squares are the tanks of the Japanese army, we have found them!" ”

Wang Rui said: "That's great, you hurry up and take pictures, and when the photos are taken, we will entertain them with rockets!" ”
