As thousands of people watched, the rotorcraft's engine roared and the fuselage began to move forward slowly!
Although in terms of appearance structure, both gyroplanes and helicopters have two propellers, a large propeller at the top and a small propeller at the tail, in fact there are fundamental differences in the principles of the two aircraft.
Simply put, the lift rotor of a helicopter rotates at a constant speed driven by the engine, and obtains different lifts by adjusting the inclination angle of the blades. This is similar to a car's gearbox.
Then the helicopter flew up, and then controlled the flight direction and pitch angle through the tail rotor and tail fin at the tail.
Not so with gyroplanes.
The rotor on the top of the gyroplane is unpowered, but it naturally has a certain inclination angle with the horizontal central axis of the fuselage. The propeller at the back is the power propeller of the gyroplane. It provides horizontal backward thrust to push the gyroplane forward and accelerate. , then the tilted top lift propeller hits the wind, starts to rotate naturally, and provides lift, and finally takes off slowly.
As for direction and angle control, it is through the horizontal and vertical tail fins behind the rotorcraft's power propellers.
At this moment.
As the engine speed of the rotorcraft further increases, power is transmitted from the engine to the drive propellers, and the blades cut and push the air. There is a strong wind behind the rotorcraft, which in turn pushes the rotorcraft to start moving and accelerating!
"Buzz buzz!"
In the roar of the engine, the speed of the gyroplane is getting faster and faster. The lift propeller on the top collides with the air and rotates. At the same time, the angle of the blade begins to provide downward wind pressure and obtain upward lift!
"It's flying! It's flying! It's really flying!"
"Hahaha, awesome! This is so awesome!"
"Who would have thought that our machinery factory would one day be able to build airplanes?"
"Isn't that right? To be honest, I want to go up there and give it a try."
"Hey, there will be a chance in the future!"
The moment the rotorcraft left the ground, the originally noisy discussions among the countless onlookers turned into uniform cheers, and thunderous applause spread like a tide!
For this factory, which is like a big family and has lived together for decades, the sense of belonging is unimaginable, and every progress of the factory makes them feel strongly involved and honored!
The light of glory shines on everyone, and their cheers come completely from the heart!
"Very good! Very good! Steady the rudder!"
"Start turning! Yes, yes! Turn right and slowly pass through the field, prepare to start landing!"
"Slowly lower the accelerator! Yes, yes!"
On the plane, he felt the strong wind blowing on his face. Fortunately, he was wearing goggles. He was driving the gyrocopter less than two meters from the ground. Chen Hang, who was flying in the air, tried to control his agitated mood and listened to the factory director. The slogans shouted out through the loudspeaker were followed in an orderly manner according to the training given to him by the previous factory director.
Not long after, the gyroplane slowly landed again, and its three simple small wheels landed on the ground very smoothly without much impact. Then the aircraft began to slide and slow down, and the tail drive propeller engine began to gradually slow down.
The moment the rotorcraft stopped, a group of people behind Wang Ye rushed forward. The fastest one was naturally Lao Chen!
"Hahaha! As expected of my son! Hahaha!"
"From today on, my son will be a pilot! Hahaha, awesome or not! Envy or not! Hahaha!"
Lao Chen rushed up and looked at his son carefully. Seeing his excited expression, he couldn't help but get excited and started to show off by yelling.
Others around him also agreed. As for the look of envy, it was natural that it was indispensable. After all, it was an honor to fly a rotorcraft for the first time!
"Come on, come on! Smoking! Smoking! Great China! Have you never smoked?"
"I, Lao Chen, have never smoked one either! Come on! Come on! They're all there! They're all there! One for each person! Don't take more!"
The next second, Lao Chen took out a few packs of Zhonghua cigarettes from nowhere. In this era, these cigarettes were considered the top cigarettes. He didn’t know where he bought them from, and started giving them to other engineers around him. They distributed it.
Seeing this scene, the technical section chief couldn't help laughing and scolding:
"I said Chen Laogou, you have been ready to celebrate for a long time, right?"
"Even Greater China bought it in advance? Hahaha!"
In an instant, there was a burst of laughter, and Lao Chen looked proud and said with a smile:
"That's necessary! The aircraft was designed by the factory director, and the parts were produced by us. I, Old Chen, have measured them one by one. There must be no problems!"
"Isn't it inevitable that the test flight will be successful? Hahaha, the key is that my son can fly well!"
"Hahahahaha!"
Hearing Lao Chen's hearty laughter, the technical section chief smoked the Great China and cursed angrily:
"Bah, have you forgotten how scared you were just now?"
"Are your legs shaking like chaff?"
Immediately, the scene burst into laughter again. Lao Chen was not afraid of being exposed because he was already the father of a pilot. This was called openness and pride. He felt even happier than when he went up there.
"Director, thank you for giving Chen Hang this opportunity."
Finally, Lao Chen opened a new pack of Great China, walked to Wang Ye respectfully, bowed solemnly, handed over a Great China, and said very seriously.
Wang Ye was not polite. After Lao Chen lit the fire, Wang Ye took a sip and said with a smile:
"I didn't give him the chance, it was him who fought hard and got the chance himself."
"Okay, after smoking this cigarette, our test will continue,"
"This time it is not a ground-to-air flight. It has to fly to an altitude of at least fifty meters and fly around the field. The entire stay in the air will last nearly ten minutes!"
"Don't throw cigarette butts on the ground. After you finish smoking, check the aircraft quickly and be careful!"
"After Group A has inspected Group B, if problems are found in the second round of Group B's inspection, Group A's corresponding position will not receive this month's salary!"
The reason why Wang Ye set up the backup check of Group A and Group B was just in case. After all, he was testing his own children in the factory, so he couldn't be too careful. If something went wrong, Lao Chen would probably want to die. .
As for how customers will check after buying it in the future, that has nothing to do with Wang Ye. Anyway, the maintenance manual is clearly written. If you don't follow the requirements, you will be responsible for any problems if there are any problems.
At the same time, when he heard Wang Ye say this, Lao Chen's hand holding the cigarette trembled, and half of the Great China dropped to the ground. He quickly picked it up and stuffed it into his mouth, and said dryly with a nervous look on his face:
"I'm going to use the bathroom and I'll be back in a minute."
"Ten minutes at most"
Then he hid in a hurry, not daring to watch the next test.
But this time, no one laughed at him anymore, because everyone knew that every test had risks, even if it was only fifty meters high, it was enough to make a person shatter to pieces!
"Be careful!"
With the voice of the technical section chief, the scene became busy again.
After a while, after the two groups confirmed that there was no problem, the gyroplane began to glide and take off again. Thanks to Wang Ye's excellent design, even when the engine power was not that big, the gyroplane was still less than thirty meters away, and it directly took off. Lift up and fly!
"Buzz buzz!"
The sound of the engine reverberated in the air. Under the gaze of thousands of people in the machinery factory, the gyroplane gradually pulled up, and soon exceeded the height of all the buildings in the machinery factory, hovering in the air.
"how do you feel?"
On the ground, Wang Ye held a loudspeaker and shouted at the sky.
"Feels good! Very good!"
"I saw most of the factory, and everyone has become smaller! Hahahahaha!"
From Chen Hang's voice, you can hear how excited he is, and his response made the crowd watching below extremely envious, especially the young people.
"Made, if you had known I would have written an application too!"
"Hahaha, with your little courage, you dare to fly so high?"
"Although I am very envious, I am self-aware. I am afraid of heights. I will definitely not dare to go up."
"Hey, it's okay. From now on, my brother will sit in the front and drive, and you will sit in the back. Let's also experience the feeling of flying!"
"Yes! I wonder if the future factory director will let us give it a try."
In the crowd, young people looked at the gyroplanes flying in the sky and couldn't help talking with eager faces, full of longing for the sky.
Gyrocopter flight testing is still ongoing.
Yuntai City, department store.
"Hello, you two?"
"What do you need? An electric fan or a washing machine?"
"The price of our electric fan is 280 yuan and the price of the washing machine is 360 yuan. We don't need industrial coupons."
"If you buy two units at the same time, you can get a discount of 20 yuan, which means you can own a large floor-standing fan and a double-cylinder washing machine for only 620 yuan."
“And we are responsible for delivering it to your door and installing it in place for you.”
At the Hongxing Manufacturing Factory stall, due to the sufficient supply of production materials and the thousands of people working overtime, the sales of electric fans and washing machines have been changed to twice a week, on Wednesdays and weekends.
Moreover, the rush to buy in the past no longer exists. Although there is still an endless stream of people buying, the overall sales situation has become calmer.
"You can pick it up and weigh it. Our appliances are of very solid workmanship."
"Whether it's an electric fan or a washing machine, steel materials account for more than 90%, which is very heavy!"
"A little girl like me can't even carry it."
"You can try it!"
Inside the stall, Xu Jiaojiao was wearing a customized sales uniform and was explaining electric fans and washing machines to a customer. When he heard what he said, the husband, who looked like a middle-aged couple, glanced at his wife and then smiled. Moved a bit.
"Hiss! It's very heavy! It must weigh at least forty pounds!"
"In the past, it was indeed a military factory that made weapons. The quality was indeed guaranteed!"
After the middle-aged man put down the electric fan, he nodded to his wife with great approval and said, while Xu Jiaojiao next to him took advantage of the opportunity and said:
"You are right, we focus on military quality, there is no ambiguity."
"Within one year after you purchase it, if there is a problem with normal use, you can call our after-sales hotline or come to the counter to register, and we will come to you and replace it with a new one free of charge."
"If there is a problem within three years, we will pick up the goods, deliver and repair them free of charge."
Within a moment, the couple paid the money with a smile and left with the tickets in hand. The two young porters followed behind carrying an electric fan. Not only did they send the fan back, they also took the two The mouth was also sent back.
At the same time, dozens of meters away, four people witnessed the entire process. The leader was an old man with an eyebrow. Among the remaining three people, there were two middle-aged people with gray hair, and one looked very tall. A young woman in her early twenties, with a rather delicate and charming appearance, attracted the customers and even the salespersons who were coming and going, and couldn't help but turn their heads to look at her.
"In just a short time, we sold twenty-one electric fans and thirteen washing machines!"
“I really didn’t expect that the sales of electrical appliances would be so good!”
Among the four people, the middle-aged man with very high cheekbones and a powerful look looked sharply at the Red Star Factory stall in the distance, sighed and said this, while the middle-aged man next to him nodded and said:
"Isn't that right? If we had known this thing was so easy to sell, we should have done it before!"
"And I don't think it's difficult to make this thing at all."
"Why did they let them take the lead? The municipal party committee purchased 600 units in one go, with a total payment of 160,000 to 70,000 yuan!"
As soon as he finished speaking, the old man Lian Xinmei standing in the middle snorted and said disdainfully:
"How much does the 600 units from the municipal committee cost? In this period of time, how many have they sold? Have you calculated how much money they made?"
"I think this electric fan will cost no more than fifty yuan."
At this moment, a customer passing by suddenly heard the sound and couldn't help but sneer and said:
"Comrade, who doesn't know how to brag?"
"The cost is fifty yuan? Then you produce electric fans for us! How about selling them for sixty yuan? I can't let you guys work in vain. Let you earn ten yuan, which is not a small amount, right?"
"When the time comes, I will also become a villain. How much do you have, how much do I want?"
"How's it going? When will your electric fan be made?"
As soon as these words came out, the customers and salespeople who heard them nearby couldn't help but burst into laughter. The faces of the four people changed instantly. The only difference was that the other three were angry and disdainful. The pretty woman was frowning.
"Summer insects cannot speak of ice!"
"Let's go back to the shipyard and discuss the production of electric fans and washing machines."
"Since a third-tier factory like their Hongxing Factory can do it, there is no reason why our Dangtang Shipyard can't do it!"
"We still have plenty of steel anyway, and it would be a waste to pile it up there."
“I think it’s good to reuse waste!”
Finally, the old man snorted coldly, waved his hand and led several people out of the department store. After a while, he returned to Jeep 212. As soon as he got in and closed the door, the pretty woman sitting in the passenger seat said hesitantly:
"Dad, I think this matter is not that simple. We should study it carefully."
As soon as these words came out, the old man sitting behind him couldn't help laughing and asked:
"What's not simple about this? I think it's very simple. Isn't it just a few blades, an iron rod, a few iron casings, and an electric motor?"
"Don't we have something like this ready for our shipyard?"
"If there were no production tasks, the factory would be out of business. Do you think I would be willing to do this kind of work?"
"walk home!"
Then, the car rumbled off, aiming for the Yuntai Shipyard!
