Chapter 561 Demonstration of Vertical Takeoff and Landing

Mr. Wu also stayed there to help, so Qin Tao and Xu Zhengyang were left to hang out together.

The venue is large and there are many people. After all, this air show is different from the International Defense Exhibition. There are not a few days dedicated to only professionals to visit. This is the first time the air show is held, and there are too many visitors.

"Mr. Qin, you are very polite to them." Xu Zhengyang was still mentioning what happened just now: "Do you have any purpose for them?"

"Zhengyang, why are you always like this?" Qin Tao educated his secretary: "When I do some good deeds, you will think that they have a purpose, just do it casually."

“Mr. Qin, I thought so before, but everything you do casually turns out to have profound meaning in the end. I want to learn more from you.”

Qin Tao smiled and said, "Okay, then just take a look. My operation this time should be quite beautiful. We can get a lot of benefits in the future."

 “What’s the benefit?”

“You will know later.”

"Qin!" At this moment, an excited shout suddenly came from the opposite side. Qin Tao looked over following the sound and saw a familiar figure.

“Weina, are you free to visit the air show?”

 The visitor in front is none other than Vitalia, whom I haven’t seen for a long time!

When purchasing the aircraft carrier, Qin Tao and Vitalia worked closely together. However, after all, Qin Tao had a lot of things to be busy with, and Vitalia was also looking for her own fun, so the two did not meet often after that. On the other hand, there is more and more money lying in the accounts of green innovation companies.

This time the air show was held, not far from Ma Port, and Vitalia came over to join in the fun.

　　Not only her, but also the bodyguard Ivan who has been protecting her, and the secretary Yang Qianer.

After seeing Xu Zhengyang, Yang Qian'er was also very excited. Her big watery eyes looked at Xu Zhengyang and could no longer be separated.

"Yeah, of course I'm free. The blocked ship hasn't been built yet. What can happen to our Chuanglu Company?" Vitalia said, "We just came here to join in the fun, but we don't understand many things. , you came just in time to explain it to us."

If it were someone else who asked Mr. Qin to be the commentator, that would definitely make people sneer at him, and he wouldn't even throw urine and take a photo. Who do you think he is?

　　However, Vitalia has this qualification.

“Okay, I’ll take you around and introduce it to you.” Qin Tao said: “As a shipbuilder, I am definitely no amateur when it comes to airplanes and rockets.”

"Okay. There is one over there. They advertised it as the Beautiful Man in the Sky, but we really didn't realize how beautiful it is."

A handsome man in the sky? Isn’t it the J-8?

 Qin Tao led everyone over.

The tapered nose, air intakes on both sides, and slender body are indeed J-82s. The dark green nose, white fuselage, and red flowers look very festive. There is an F painted on the nose. -The words 8IIM.

"The F-8ⅡM aircraft is a miracle in the history of the development of my country's aviation industry. Its development cycle is short, fast, high quality, and cost-effective." At this time, there was someone making an introduction next to the aircraft. This person was wearing a pilot's uniform. The costume looks very handsome and chic: "The superior maneuverability of the F-8IIM allows me to do many difficult actions that I wanted to do but couldn't do in the past. This is currently our best-performing fighter jet."

“Excuse me, shouldn’t the one with the best performance be the J-31A exhibited by the Mingzhou Group?” When they heard this, the onlookers finally couldn’t help it anymore.

 It’s normal for Wang Po to sell melons and boast about herself, but she can’t ignore the actual situation and talk without shame, right? Talking about the best-performing aircraft, isn’t this just empty talk?

"Everyone, my expression just now was a bit loose." The commentator looked at the beautiful foreign woman and immediately followed suit: "I mean, among the aircraft that can be put into service at any time, ours has the best performance. The performance of the J-31A is very advanced, but it still has a long way to go."

Qin Tao smiled: "Vitalia, you have been in the East for so long, and you still haven't learned the subtlety of us Orientals. If others want to brag, just brag. Why do you need to expose others' shortcomings?"

Of course, the question just now came from Vitalia. Qin Tao criticized her, and Vitalia immediately accepted it humbly. However, the face of the person introduced at the booth was hard to look at.

 A person in charge had already walked over with a gloomy face, but when he saw Qin Tao clearly, he suddenly changed into a smile.

“Mr. Qin, we thought it was you who came to kick off the competition. If we knew it was you, we would just lower our heads and listen. Are you interested in our aircraft?”

When the Su-27 was introduced before, Qin Tao had cooperated with people from the 601 Institute. The person in front of him was the one who had come into contact with Qin Tao. He was secretly glad that he didn't offend Mr. Qin by talking nonsense. Then it will be even more troublesome.

“People around me are interested in this aircraft, so they came over to take a look. I just felt that there was something wrong with the presentation, so I asked a few questions. I hope I won’t disturb you.” Qin Tao said.

"Of course not." The person in charge said: "We welcome your valuable suggestions. Mr. Qin, when you go out in the future, you can also introduce us to us, in case we can sell the aircraft."

Mr. Qin has the strongest ability. As long as Mr. Qin helps, their aircraft will definitely be sold!

Qin Tao smiled: "Of course. If there is a chance in the future, I will definitely introduce it to you. What are the characteristics of your aircraft?"

"It inherits the high-altitude and high-speed characteristics of previous models and can quickly complete takeoff and interception. At the same time, we also used Beetle radar and R-27 missiles to give it mid-range interception capabilities. Its overall performance has reached the leading level of this era. .”

 Sure enough, it’s still the same old thing, actually using Lao Maozi’s avionics to replace it, it’s better to use domestic manufacturers’ avionics! What about high-altitude highways? They have long been outdated!

 It’s a **** thing if it sells!

“Okay.” Qin Tao smiled and nodded, then looked at Vitalia aside: “Is there anything else you want to ask?”

Vitalia shook her head. She didn’t understand at all, and there was no point in asking.

“Then let’s go over there and take a look at the business jet. It’s time for your green company to buy a business jet. It will be more convenient to go out.”

Vitalia’s eyes lit up: “Okay, our company should also have a business jet!”

At this air show, many foreign manufacturers have come, and all of them are civilian models. We hope to open the door to the East. The air show is not only for displaying various equipment, but also for doing business. This is It is similar to the car shows of later generations.

Vitalia doesn’t know much about these fighter jets, but when it comes to business jets, she is very interested.

“Our domestic Mikoyan Design Bureau once planned to make the MiG-25 a business jet. If such an aircraft appears, it will be a supersonic business jet.”

The MiG-25, a double-triple fighter, has indeed been modified as a business jet. I don’t know how long this business jet can fly at supersonic speeds, but it is obvious that this thing is definitely not suitable for the business market. After all, it consumes too much fuel.

There is no such business aircraft in front of the Mikoyan Design Bureau's booth. They continue to sell the MiG-29, which is their flagship product after all.

The morning passed quickly while walking around, and Vitalia did not find a suitable business jet. After lunch, the most important flight show at the air show began in the afternoon.

The first to perform was the Bayi Aerobatic Team, a professional aerobatic team from the East. They used the J-7E, which is adapted to low-altitude flying, as a performance aircraft. Their various maneuvers made countless audiences applaud. The exhibition reached its climax in the flight show.

A large group of people had already gathered around Mingzhou Group’s booth. Of course they remembered what the people at the booth said in the morning: In the afternoon, a vertical take-off and landing performance will be performed here!

This kind of performance does not require a runway, and they do not need to follow the exhibition organizer's arrangements. They can just prepare themselves. Anyway, this is an apron and will not interfere with the normal flight performance.

 When a power supply car drove over, everyone became even more excited.

Schnoder stood outside the cordon, looking at the plane preparing to take off, with mixed feelings in his heart.

 This plane is going to fly, and it will take off and land vertically! The progress of the Orientals is really fast!

 What about our own side? We are still arguing over the technical route! McDonnell Douglas adopted the same lift engine method as the Yak-141 and felt that this method was safer. However, the problem of tail flames burning the deck was difficult to solve, so they wanted to use this lift engine method. , but this is just like the East. When will it be their turn to follow others and eat cold food?

With mixed emotions, Schnoder heard the roar of the engine. The vertical take-off and landing version of the fighter in front of him started its engine, which meant that the official flight test was about to begin!

 Can it really take off vertically?

Countless camera lenses started to flash, and they wanted to record this most exciting moment. The world's third vertical take-off and landing fighter finally took off vertically!

Sea Harrier has been equipped with a large number of troops from various countries, and has been very popular in various battles. The Yak-38 is useless. It was equipped with aircraft carriers and was transferred to land soon. What about this aircraft in front of you? Can it become an important vertical take-off and landing fighter in the future world?

 As everyone watched, the roar of the engine became louder and louder.

At this time, the Bayi Aerobatic Team has completed all the performances and has landed. The second aerobatic show has not yet started. For a time, this place attracted the attention of countless people. Is the plane on the tarmac about to take off?

 Vertical takeoff and landing?

　　　Countless people cheered and gathered around.

 The test pilot took off the plane.

 Suddenly there was dust flying under the fuselage. This was the combined power of the vertical fans on the front!

How did they do that? How much power needs to be transmitted forward through the rear drive shaft? Tens of thousands of horsepower! Transmission shafts and clutches all need to withstand such a huge impact. How can Easterners solve such technical problems? What technical route did the Easterners take?

 Schnoder was very curious.

At this time, Zhao Dangsheng was still making introductions, but the roar of the engine had suppressed his voice, turning him into acting in a silent movie.

“Everyone, watch out, our plane is about to take off. In our idiom, this is called pulling onions on dry land! Watch out, everyone!”

 Only the person closest to him heard it and gave a thumbs up. Then, the roar of the engine continued to increase, and the dust around him began to spread rapidly outward, as if a monster was about to appear in Journey to the West.

The black fighter plane was still clearly visible in the dust. Schnoder looked at the color of the flames ejected from the engine's nozzle and was a little surprised. The engine hadn't turned on afterburner yet. Is it enough to use conventional thrust?

When taking off and landing vertically, the aircraft needs to provide the maximum thrust, so only turning on the afterburner is enough. However, the tail flame ejected from the engine has to rotate ninety degrees to reach the ground, which is reduced, Jacques- During the test of 141, the ablation deck was mainly caused by the lift engine at the front, but the main engine at the back still worked stably.

If this J-31A wants to take off with a full load, of course it has to turn on the afterburner, but now it is just for on-site display and not a combat mount. The fuselage is very light, and ordinary military thrust is enough. In this way, Come on, the flames ejected from the tail nozzle are not so hot anymore, and they look more practical.

When it is officially put into production in the future, perhaps the modified turbofan-15 will also come out, and the thrust will be more powerful.

At this time, the engine was roaring and the fuselage was shaking slightly. Schnoder could clearly see that the fuselage was beginning to rise! The hydraulic rods of the landing gear lengthened, and then the tires lifted off the ground.

 Flying.

 Just like that, it’s flying!

 From a distance, Qin Tao was watching all this, and his heart was surging.

 This is a new era!

 The era of vertical takeoff and landing in the East is also coming. This fighter will give the army in the East the ability to take off and land vertically! Whether it is an amphibious assault ship, an island in the south, or other needs in the future, the military will have one more choice!

 The onlookers applauded.

They also witnessed a miracle. The world's third vertical takeoff and landing fighter finally completed vertical takeoff and landing for the first time. It is quite rare for such an aircraft!

After all, both the Sea Harrier and the Yak-38 are light fighters, with a total weight of only about ten tons, and the current J-31A is a medium-sized fighter. When taxiing to take off, its The take-off weight may even reach twenty tons!

The nozzle at the tail is spraying out fiery red gas, and the lift fan at the front is spraying out cold wind. At the same time, the nozzle on the outside of the wing is also spraying out airflow, adjusting the state of the aircraft. At this time, the fuselage is shaking a little, but it Still persisting.

This flight demonstration will give reassurance to many people who are still watching. They will firmly choose Dongfang's J-31A fighter as their standard equipment. The J-31A will raise more funds. Lots of R&D funding!

The camera is still taking photos, and the video recorder is recording non-stop, recording this wonderful and beautiful moment.

The J-31A fighter jet was about two meters above the ground and maintained a hovering posture for more than ten seconds. Then, the aircraft began to land slowly. When the wheels made contact with the ground, this unique flight display was already over.

However, the onlookers were still immersed in the excitement just now and couldn't help themselves. Their faces were excited and their mouths were full of praise.

 “That’s awesome, the lift fan method is no problem!”

“That’s right, I heard that this set of lift fans was made by Mingzhou Group. No matter what they do, they are always so good!”

“That’s right, the little lift fan can’t stop them at all. People have started building rockets to conquer Mars!”

Amidst the various praises, a huge sense of disappointment emerged in Schnoder's heart. How he wished that the aircraft that had just performed a vertical take-off and landing flight performance was his own aircraft! When will the McDonnell Douglas plane make its first flight?

 Or do you have to tear it down and start over?

 Schnoder's face was extremely troubled.

“Excuse me, how long did it take for you to develop this vertical take-off and landing system?” A reporter has already begun to ask impatiently.

"Five years have passed since the establishment of the project. We first did two years of conceptual design, and then two years of prototype testing. It was not until this year that we started to assemble it on the aircraft. Now, this is it The twelfth vertical takeoff and landing test." Zhao Dangsheng introduced.

 Five years! This power system has actually been developed for five years! Schnoder's mind was filled with mixed emotions. How many years would it take for McDonnell Douglas to engage in research and development?

 Schnoder couldn’t imagine it.

“What is the biggest problem with this vertical take-off and landing device?” someone else asked.

"The biggest problem is of course the combination and transmission of power." Zhao Dangsheng said: "Everyone should know that we need to rely on a lift fan to provide lift, and we need to combine 30,000 horsepower from the rear engine. In the combination of power and When it comes to disconnection, there needs to be a specialized agency.”

 “Then how did you achieve it?”

Hearing this question, Zhao Dangsheng frowned slightly. If he continues to say this, the secret will be leaked! At this moment, a figure appeared beside him.

"If we use conventional methods, of course we cannot achieve power transmission. We Easterners are the smartest and have invented a special soft combination method." Qin Tao started to introduce to everyone with a smile: "Simply speaking, the main method is The transmission shaft drives a blade, which stirs the hydraulic oil and pushes the opposite blade, thus achieving power transmission."

This is the principle of the common hydraulic torque converter on AT gearbox!

At that time, in the automobile industry, because the automatic control problem of the clutch could not be solved, a special hydraulic torque converter was invented for the automatic transmission. It has been used to this day and is also the best choice. Unexpectedly, Easterners actually use it. This way!

I have to say that this method should be the best solution. Otherwise, it would not be easy to combine and disconnect tens of thousands of horsepower!

Zhao Dangsheng breathed a sigh of relief. The lift fan system is the most important system of the entire vertical take-off and landing fighter. Of course, the internal principles of these systems cannot be easily leaked. It should be the best thing to fool them now. If others If you want to imitate, you will go further and further down the wrong road.

"Of course, even so, the power that needs to be combined is still too strong, so we use a special transmission shaft." Qin Tao continued to lie: "This set of lift fans has two sets of blades. We use them separately. It is driven by one transmission shaft, which further reduces the power transmission requirements. In order to save volume, the two transmission shafts are coaxial, which is somewhat similar to our dual-rotor engine."

With two drive shafts, the power transmission is reduced from 30,000 horsepower to 15,000 horsepower. It sounds like that, but in fact, this will greatly increase the complexity of the system and increase the failure rate.

What Qin Tao said can make people who try to imitate go further and further down the wrong path.

“Yes, this is a solution to the problem!” An engineer on site nodded and agreed with the solution of adding a drive shaft.

"Of course, even with these methods, the development of the lift fan still cost us a lot of energy. Fortunately, we have developed it. Our Mingzhou Group has such strength. Our technology has developed too fast. It makes us feel like we have alien technology!”

Hearing these words, Schnoder felt a chill. This was a show off, a naked show off!

Furthermore, this statement is clearly something only Americans are qualified to say. When the F-117 was first made public, an Air Force officer excitedly declared to all reporters: We are like getting alien technology.

At the time, the F-117 was indeed sci-fi enough, giving people a perspective of alien technology. But now, the tide has turned, and it is actually the turn of the Orientals to say so!

  Schnoder felt very uncomfortable.

“Excuse me, you use a lift fan, which takes up a lot of space in the aircraft. Will this reduce the fuel capacity of this aircraft and make the range less than the ordinary version?” Someone else spoke.

"That's right." Qin Tao admitted this issue simply and neatly: "Compared with the ordinary version, its range has been reduced a lot. However, we cannot compare with the ordinary version. We have to compare with other vertical ones. Compared with taking off and landing fighter jets, the performance of our aircraft is quite good."

If the space where the huge lift fan is located is freed up, it can hold at least two tons of fuel, which means a range of more than 500 kilometers. Now, with this design, the range has been reduced a lot.

Any vertical take-off and landing fighter has a very short range. The Sea Harrier sounds very impressive. In fact, if it takes off and lands vertically, its range is only about 100 kilometers. It is a proper mast defender, but the British Ski jump takeoff is often used to reduce fuel consumption, but the Yak-38 does not have this function.

"We can guarantee that in the case of vertical take-off and landing, its range can exceed 500 kilometers, and in the case of ski-jump take-off, the range of this aircraft will exceed 1,300 kilometers. Its data will be far Far more than existing vertical take-off and landing fighters."

PS: My heart is feeling very uncomfortable. The Hero of East China has been worried all night. Forget it, it’s better not to go all out and update it every few days. It is said that myocarditis can be fatal. It’s so scary.
