She has a ponytail, an oval face, and fair skin. She looks like an actress. However, the flight helmet she is holding in her hand is not a decoration. Looking at her appearance, Qin Tao was a little distracted for a moment. Our country has already There is a girl who flew away and is still so beautiful?

“Report, pilot Zhao Liang.”

 “Pilot Xu Can.”

 “I was ordered to carry out a test flight mission.”

Both of them saluted Ma Sheng, indicating that they were pilots of the Army Airlines. Wu Shengli looked at Qin Tao with a smile: "Taozi, do you look good?"

 “So handsome.” Qin Tao replied.

After I finished my answer, I realized that what I said seemed inappropriate. Is it inappropriate to praise other girls in front of my father-in-law?

However, Wu Shengli didn't seem unhappy. He continued to nod: "Yes, in our army, there are many girls who are not inferior to men. We have female soldiers in the navy and even female marines. In our There are also female pilots in the Army Aviation and Air Force.”

After hearing what Wu Shengli said, Xu Can saluted him: "Report, we lesbians are no worse than **** men. We can do what **** men can do. This first flight is at my strong request." Only then are you allowed to fly with **** men. I will show it with my actions. We lesbians can also complete the most dangerous and difficult tasks! We can do everything!"

Qin Tao nodded: "Dad, I suddenly feel that we should also include female astronauts in the selection of our astronauts. Where there are lesbians, it will greatly improve the work efficiency of our **** men. The matching of men and women , work is not tiring.”

Xu Can looked at Qin Tao with his bright eyes, looked at Qin Tao's still young face, and looked at him chatting and laughing with other leaders, and suddenly thought of something: "Are you Mr. Qin? Mr. Qin from Mingzhou Group ?”

“Well, it’s me.” Qin Tao nodded: “Do you know me?”

“Of course, our Zhishi R&D team laments almost every day that if it weren’t for Mr. Qin, this aircraft would not have appeared at least ten years later. You are the greatest support for our domestic military research and development.”

Xu Can said.

“No wonder I sneeze every day. It turns out they are talking about me behind my back.”

 Pfft, Xu Can smiled, his smile was so bright.

Originally, the first flight ceremony should be more grand, but with Qin Tao's involvement, the atmosphere became a bit special. Ma Sheng said from the side: "Mr. Qin, we are preparing for the first flight. Do you have anything to say to the pilot?" Tell me?"

 Hurry up and say a few words of encouragement and shut up! This was Ma Sheng's idea, but Qin Tao was not polite.

“Of course, do you have any extra helmets? Give me one.”

 “What can I do for you?” Xu Can was curious.

“I also want to go up there and experience the feeling of our Z-20 taking off.”

Wu Shengli on the side immediately shook his head: "Nonsense, I brought you here to participate in the first flight ceremony, not to let you fly. Just now this girl also said that you are the supporter of our domestic military industry, how can you do something dangerous? matter?"

“Well, Dad, you taught me the right lesson.” Qin Tao replied.

Xu Can looked at the father-in-law and son-in-law curiously, wondering what Mr. Qin wanted to express.

“How about I get an extra helmet? Dad, can you go up with me?” Qin Tao continued to ask.

Wu Shengli actually nodded: "That's pretty much it."

Ma was speechless on the side. Lao Wu, what are your principles?

"Okay, I'll get it." Xu Can actually took it seriously and turned around and walked back.

"Come back, don't listen to their nonsense." Ma Sheng said: "Today's test flight, just the two of you will go up, now..."

“Uncle Ma, why don’t I get you a helmet too?”

"In the future, when we pass the test flight and finalize the service, we will have plenty of opportunities. What are we going to do now?" Ma Sheng rolled his eyes at Qin Tao, but then thought of something: "However, it is okay for me to go up. After all, I have been flying for so many years... "

etc! Ma Sheng shook his head and was almost led into a ditch by Qin Tao!

"Mr. Qin, do you have any more questions? Forget it if you don't, we are about to officially make the first flight." Ma Sheng continued.

“Okay, I have one last question.” Qin Tao said: “I can understand fighter pilots wearing helmets. After all, we have to eject and take off at any time. Why do we helicopter pilots wear helmets?”

Most helicopter pilots wear earphones. On the one hand, they can isolate the roar of the engines above their heads, and on the other hand, they can make calls easier. After all, there is a microphone protruding from the side of the earphones.

Except for armed helicopter pilots, ordinary helicopter pilots don't really need to wear helmets. After all, even if the helicopter has an accident, it cannot eject and can only fall hard.

Ma Sheng rolled his eyes and then looked at Xu Can: "Xiao Xu, please answer Mr. Qin's question."

"Hmm." Xu Can looked at Qin Tao with a bright smile on his face: "We have to go around the plane to check before taking off. This helmet prevents us from bumping into each other during the check."

Ma Sheng glared at Xu Can, this girl actually got naughty with Mr. Qin.

Xu Can ignored his gaze and continued: "Mr. Qin, do you understand?"

 “I understand, you are making fun of me.”

"Really? Then tell me, what is the use of this helmet I am wearing?"

“I see there’s an interface on this, it should be for connecting to a night vision device, right?”

"Yes, although we fly a transport aircraft, we not only fly during the day, but also at night. We need to attach night vision devices, so we also wear helmets at ordinary times, which can make us more adaptable."

In the beginning, the first-generation helicopter pilot helmet was not much different from the fighter pilot helmet. It consisted of an outer hard protective layer and an inner soft pad, the interlayer between the two, and the communication equipment attached to the inside of the helmet. Device composition.

It's just that the helicopter flies at a low altitude, so there won't be any increase problems, so there is no oxygen mask on the helmet, so you can just use the oral microphone. There is no need for a fighter jet's laryngeal microphone or oxygen mask microphone. Moreover, helicopters Flight helmets are generally dark green, which is different from the white and gray colors of the Air Force.

 However, with the development of technology, helmets have also begun to add accessories.

The most important thing is of course the night vision device. If you want to fly at night, you need a pair of sharp eyes. If you don’t have the eyes of an owl, you can use technology to achieve it. Night vision devices are quickly becoming more common, and helicopter pilots must also adopt them.

 Of course, this is just a simple change. With the further development of technology, helicopter helmets have begun to add more components.

“In the future, as our technology becomes more advanced, these goggles can be turned into a display to display various data during flight.” Qin Tao said.

“Can the goggles be turned into a display? Is it the same as a fighter plane’s HUD?” Xu Can’s eyes widened.

 “Well, it’s even more advanced than the HUD.” Qin Tao nodded.

“If we really have this kind of equipment, it will be really good news for our pilots.” Xu Can nodded: “At that time, all our pilots will be grateful to Mr. Qin.”

“Okay, let’s start the pre-flight inspection now.” Masheng said. If he didn’t interrupt, he was afraid that the two people would continue talking.

 Qin Tao stood aside and watched the two pilots going around the aircraft to check. This was a routine inspection before flight. Although so many technicians had already checked it, the pilots had to do it again.

Xu Can walked carefully around the plane, looking pretty.

Looking at Qin Tao's eyes, Wu Shengli asked with doubts, "Taozi, are you really attracted to her?"

"How could it be, Dad, what are you thinking?" Qin Tao rolled his eyes at his father-in-law: "Zhengyang has been with me for so many years, has he ever seen me messing around with women? To Xu Can, a young helicopter pilot, I just There is just a kind of approval, just like a brother to a sister, an elder to a junior. I admire her very much, but this appreciation has nothing to do with the relationship between men and women. I believe that when our straight twenties are publicly displayed in the future, if Xu Canlai will be the commentator of this plane, and he will definitely gain the appreciation of the whole people, just like how I feel now."

Wu Shengli smiled: "I'm sorry you don't dare either."

 After the inspection, Xu Can and Zhao Liang boarded the plane. The relaxation just now disappeared, and the expressions on their faces became serious.

“001 call, the aircraft has completed the self-inspection, everything is normal, please start the engine.”

 “Can be started.”

A whistling sound sounded, and the two engines started successfully one after another. The top rotors also rotated, and the wind roared on the ground and blew everyone's faces.

“Everyone, retreat to a safe distance!” Deng Hui shouted.

This is a test flight after all. No one expects anything to happen, but we must be prepared to deal with all unexpected situations.

It would be tragic enough if the plane fell down, but if a few more were smashed below, it would be an even more vicious accident.

Everyone dispersed and reached a safe area, looking at the plane from a distance and at the two calm pilots in the cabin.

 “The engine is normal, please take off.”

 “It’s ready to take off!”

Following the command, Zhao Liang gently pulled the total moment, the pitch of the top rotor increased, and the whistle of the propeller became sharper. The helicopter shook slightly on the ground, and then rose up.

 Flying!

At this moment, countless people applauded. For this achievement, countless military personnel have silently dedicated their lives for decades.

At this moment, watching the helicopter take off, many people saw scenes of the development of the helicopter industry in the motherland.

In the early days, there was only the most common Z-5, which was an imitation of the Mi-4 helicopter. It still used the simplest piston engine, with slow speed, small load capacity, and backward performance. Production was finally discontinued in 1979, and 545 helicopters were produced.

 The Z-Liu was the first helicopter developed by itself. However, it was discontinued in 1980 and has not been put into service because it has serious quality defects.

After that, the country opened up and cooperated with foreign countries to develop the 13-ton Z-8 and the four-ton Z-9. These helicopters were all imported technologies, which improved the level of helicopters in the motherland. However, the localization rate was not high, and many parts were Requires outsourcing.

Just like that, now, Zhi-Twenty has finally become the first self-developed ten-ton helicopter, and its performance has reached world-class levels!

 “Hovering is normal, prepare to transfer to level flight.” The voice came again on the radio.

 “Okay, pay attention to the flying attitude.”

Following the command, Zhao Liang slowly pushed the control stick, and the nose of the aircraft began to tilt forward. The top rotor slowly moved the fuselage forward, until the takeoff and level flight tests were completed in the first test flight.

“Flight status is normal, please turn now.” A crisp woman’s voice came over the radio.

Xu Can took over the operation, and the flat-nosed Z-Twenty began to turn, made a circle around the airport, and then returned to the original take-off point.

 “Straight twenty requests to land!”

 “Okay, pay attention to safety.”

　　The altitude slowly dropped to twenty, little by little, very steadily. In terms of operating the aircraft, women relied on their delicate thoughts and gentle movements, which actually gave them an advantage over men.

Ten meters, five meters, three meters, one meter... Finally, the straight 20-meter wheel firmly touched the ground, and the first flight ended successfully!

Hearing the howling sound gradually end, Qin Tao looked around: "Is there no flower presentation?"

Generally speaking, at the end of such a grand first flight, there will be two young pioneers holding flowers to greet the test pilot. The test pilot will even get off the plane with tears in his eyes. This was the case with the J-10 test flight.

Now, isn’t this first flight of 20 too hasty?

 Ma Sheng patted his head: "No, I forgot."

forgotten?

Qin Tao looked around again and saw that the grass near the parking bay of the airport was full of small yellow flowers, so he waved to Xu Zhengyang: "Zhengyang, let's go!"

  Zhao Liang and Xu Can stepped off the plane and stood in front of the nose, heads held high.

“Report, we have completed the first flight of Z-Twenty. The performance of the aircraft is excellent and the driving experience is even better than the Black Hawk!”

“Yes, congratulations on your successful first flight. You have added a new aircraft model to our Army Airlines!”

"On behalf of the Navy, I would like to thank you for your contribution to the Zhijiang 20." Wu Shengli also spoke, looking at Zhao Liang's face, and then at Xu Can: "Especially you, a woman is not inferior to a man, I We must call on the pilots of our navy to learn from you."

"These are what I should do. I feel honored to be able to fly straight to twenty for the first time." Xu Can said, suddenly smelling the fragrance of flowers.

She raised her head and saw Qin Tao and Xu Zhengyang walking quickly with yellow flowers in their hands.

 She had a sweet smile on her face.

“These flowers are not as gorgeous as peonies or as romantic as roses, but they are full of a simple beauty, just like our young and brave pilots. On behalf of private enterprise users, I would like to express my most sincere respect to you.”

 “Thank you.” Xu Can took the flowers.

Xu Zhengyang also handed the flowers to Zhao Liang.

 The two men stood at attention again and saluted.

“Come on, this first flight is a complete success, we have to take a group photo in front of the plane.” Qin Tao looked at everyone: “Where is the photographer?”

More than twenty people stood in front of the helicopter. Wu Shengli and Ma Sheng were in the center, followed by Deng Hui, Qin Tao and others. The two pilots stood beside them, looking heroic.

 Click!

 A precious photo was taken and became a souvenir of the twentieth first flight.

“Can I go up now?” Qin Tao said, looking at the helicopter.

 “Of course.” Ma Sheng nodded.

“Mr. Qin, let me introduce you.” Xu Can volunteered.

Qin Tao first got into the cockpit and saw four LCD screens on both sides and a few simple mechanical instruments in the center.

"This helicopter uses advanced 1553B data bus technology and a redundant digital fly-by-wire operating system. The display system also uses a glass cockpit solution." Xu Can introduced: "There are a large number of mechanical buttons between the two pilots. , these are backups, and most operations can be performed on the LCD screen. Old pilots may not be used to it, but for our new pilots, these operations are very convenient."

"Helicopters often fly as high as a tree. In the past, it all relied on the pilot's quick response. However, our aircraft is equipped with a laser anti-collision radar under the nose, coupled with a digital fly-by-wire system. Once a situation is discovered, the pilot will If there is no timely response, the aircraft will automatically climb to altitude to avoid collision."

The 20-meter-long nose is also larger than that of the Black Hawk because of the equipment installed inside.

Qin Tao nodded: "Yes, glass cockpit is inevitable for the development of technology. We will train a large number of pilots in the future, and they will get used to it. Digital telex is also very powerful, which can reduce the burden on pilots and ensure flight safety. Let's go to the back have a look."

Qin Tao said that the cockpit is very advanced, but as a shipbuilder, he really can’t understand it.

 The passenger compartment at the rear is also very spacious.

"Under extreme conditions, we can carry fifteen fully armed soldiers inside, and at the same time, we can also mount a 105mm gun or a vehicle similar to a Humvee. We use a side door design to facilitate the soldiers to leave the cabin as quickly as possible. At the same time, the side door It can also carry machine guns and other equipment. Under normal circumstances, 12 fully armed soldiers can fit comfortably on the plane and have the ability to fight at any time."

Qin Tao nodded: "This place is spacious enough and can be converted into a business jet. It doesn't need too many seats, four to six will be enough, but it must have large, high-end leather seats, preferably with massage functions."

Xu Can opened his eyes wide: "Mr. Qin, do you plan to build a special plane for your own use?"

"Yes, do you want to come to our Mingzhou Group Transportation Company?" Qin Tao issued a solicitation: "I won't talk about salary or anything. If you come to our Mingzhou Group, you will definitely have a greater promotion effect on the development of the military industry. .”

 Down below, Wu Shengli and others were also looking at the plane in trance, with Deng Hui accompanying them.

"This aircraft is still prepared for the Army Aviation. Our navy wants to use it, and the helicopter needs some special treatment." Wu Shengli said: "Have you conducted research on these projects now?"

"Of course." Deng Hui nodded: "The first requirement for the helicopters the navy needs is rotor folding. Oscar is already researching electric folding technology, which takes less time and is easier to deploy and recover, allowing our navy to use it better. .”

Electric folding? Wu Shengli opened his eyes wide.

"Currently, only the SH-60 used by the U.S. Navy uses electric folding technology. The Black Hawk we introduced is a land-based version and cannot fold the rotors. Therefore, the current technology is completely independently developed by us, but our current domestic technical strength The folding wing is not a complicated project and there should be no technical difficulties," Deng Hui said.

“No wonder Oscar didn’t come. It turned out that he was developing these equipment for our navy.” Wu Shengli nodded.

The first flight of this helicopter is inseparable from the efforts of a large group of technical personnel. Oscar is one of them. He is a taciturn person who never likes to talk. He just focuses on scientific research and is unwilling to appear on the first flight. In the eyes of the big guy.

“In addition to folding the rotor, the tail also folds.” Deng Hui continued.

 Tail fin? Can the tail part be folded?

As long as it is not a coaxial reverse-rotating helicopter, it must have a long tail boom with a propeller on the side behind it. What is this used for? Turn?

It must be used for turning, but the turning of this helicopter is different from that of an ordinary airplane. This turning is performed by the rotational moment of the top main rotor. The tail propeller blows air from the side to balance the rotational moment. The perfect balance is direct flight, which is greater than With this rotational moment, the helicopter will turn in the direction of rotor rotation, and vice versa.

If the rotor is damaged, such as being shot down on the battlefield, then you can see the helicopter spinning and landing.

 The rotor at the tail is used to maintain direction, but it consumes energy. There is a trade-off: the less energy consumed, the better, so how can it be less? The tail boom must be made longer to increase the moment arm and reduce the force.

 It doesn’t matter if it’s a land-based helicopter, as long as it’s longer in the back, but for a ship-based helicopter, the shorter the tail, the smaller the hangar area required, so it’s best if the tail can be folded.

 There is no foldable model in China.

 The nine straight heads are not big in nature, and they still use a ducted tail rotor, which is destined to be unable to fold. The Ka-27 series aircraft are coaxially reversed, which requires height, and the buttocks are very short.

"Because the tail needs to be folded, the tail wheel needs to be moved forward. When folding, fold the horizontal tail upwards, close to the vertical tail, and then fold it to the left and front as a whole. This size is about the same as that of the Ka-27, and it should be able to fit in Enter the Ka-27’s hangar.”

 It’s almost the same as the Ka-27! Wu Shengli was even more excited: "If these are done well, our navy will give a bonus to the research and development personnel!"

The Navy has a headache because of the problem of universal helicopters. Different helicopters require different hangars. As a result, the hangars of warships are not easy to design. Now this newly developed modern ship-based helicopter can save space and can even board previous warships. Definitely good news.

“Thank you for your leadership. However, due to the development of these projects, the naval helicopter will take longer. I hope the navy can wait patiently.”

“We have patience, we have patience.” Wu Shengli nodded repeatedly: “As long as it is finalized and delivered to the troops at the same time as the army’s helicopters.”

They said it would take longer, but Leader Wu actually asked for it to be finalized at the same time?

Deng Hui felt a little pressured.
