Chapter 834 What is the concept of thrust-to-weight ratio 1.4?
Factory 320 is a typical example of foreign trade. After the development of K-8, it successfully opened the road to foreign trade, and even exported the entire production line. However, after the development of L-15, the road to export was not smooth. Although it appeared in air shows several times, it was not sold.

The reason is also very simple: too expensive!
The price of mid-level trainer aircraft like the K-8 is cheap, with one aircraft costing several million, and even exporting a production line is only about 15 million. Many countries can afford it, but the L-800 is different. The price of this aircraft is 29 million US dollars. At such a high price, second-hand MiG-[-]s and the like can already be bought in the international arms market.

Therefore, even if many countries lack high-level education aircraft, they are reluctant to purchase them. At present, only the domestic air force has purchased a batch. After all, JJ-[-] cannot simulate various maneuvers of third-generation aircraft.

This is why they are working hard to develop an attack aircraft. Only by increasing its multi-tasking performance can it be favored by users.

At this time, they were of course very excited when they heard Qin Tao say that he would help them attract foreign customers.

"Thank you Mr. Qin! As long as customers are not very sensitive to prices, they will definitely be able to match our aircraft." Shi Lao said excitedly.

This is enough to make everyone speechless. Our aircraft is brand new and can fly for 30 years, but customers always compare our aircraft with second-hand aircraft. Is our aircraft only worthy of competing with second-hand aircraft?

"Well, even if they are price-sensitive, we have a solution." Qin Tao nodded.

"By the way, Mr. Qin, we also plan to improve the carrier-based aircraft on this aircraft." Everyone was very excited, and simply told Mr. Qin about the next project.

The current trainer used by the carrier aircraft is the T-45 acquired by Wild Dog. 320 Factory used its own experience on the K-8 to carry out reverse mapping. Now this improved trainer is already the best trainer for the navy to train pilots.

After flying the carrier-based K-8, the pilots will fly the corresponding two-seater aircraft. Of course, there is an advanced trainer aircraft in between. They have to conduct a lot of training on the basis of the two-seater carrier-based aircraft, wasting time and money.

With the basis of the carrier-based K-8, everyone is full of confidence in the improvement of the L-15 carrier-based model, but because their technical strength is not strong, it is impossible to carry out several modifications at the same time, so until now, it can only be an idea, giving priority to modifying the attack aircraft.

"Of course you can. Didn't you say that this aircraft can also simulate the flight characteristics of our fourth-generation aircraft? It is inevitable to convert it into a carrier-based trainer aircraft. In the future, our naval aircraft carrier training will require this advanced trainer aircraft, and it can also be used as an attack aircraft. The trainer aircraft carried by our navy aircraft carrier can also be used as an attack aircraft when needed, especially in front of some weak opponents. We don't need to dispatch J-32 or J-[-]. This type of aircraft used to be enough."

Everyone was overjoyed: "Okay, President Qin, when the mission of this attack aircraft is completed, we will modify the carrier-based trainer aircraft!"

It is indeed very important that the L-15 has the ability to board the ship. After all, this trainer has advanced performance and can save the flight life of precious two-seater fighters. We can't let J-32 and J-[-] spend their precious life in squatting undercarriage, right?Besides, the engine used by this trainer is still Genghis Khan Aviation. Expanding the range of users of this aircraft is also good for Genghis Khan Aviation.

Moreover, this kind of aircraft uses under-rib air intake, and the front landing gear is also connected to the main beam, so that not only landing, but also take-off can use the catapult, as long as it is strengthened, the L-15 is born with the ability to board the ship.

"Boss Qin, we have another plan." The big guy continued his efforts.

"What idea?"

"We want to modify the shape of this trainer so that it has a certain stealth capability."

Stealth is a trend. Take a look at the Mingzhou Group's fourth-generation aircraft. It is because they have stealth capabilities, so they are sold at a high price. They also want to make their trainer aircraft have stealth capabilities, so that it will be easier to carry out attack missions.

"The nose and air inlet are easy to modify. It is enough to improve according to the standards of the American F-18 fighter jet. The main thing is the vertical tail. We have to change the single vertical tail into two outwardly inclined double vertical tails. The workload is a bit heavy, but we should be able to complete it. Applying a layer of stealth paint can reduce the radar reflection area of ​​our fighter by an order of magnitude, and it will be more handy to carry out attack missions."

Qin Tao smiled: "This kind of improvement, you can figure it out for yourself, I won't say anything."

If the L-15 sells well, they will be able to carry out the stealth modification by raising their own funds. If they do not sell well, they will not be able to raise funds for the improvement.

So, it's still up to them.

In Qin Tao's time and space, L-15 said that it was going to be improved invisibility, but there was no movement, and it was not even as fast as Xiaolong. Therefore, Qin Tao didn't know if this improvement would be possible, so he didn't raise any opinions.

Qin Tao inspected the 320 factory for two days, and on the third day, the customer came to the door.

"President Qin, the guests from Cuba are here." Xu Zhengyang said to Qin Tao.

"Well, let's go to the runway to meet him."

It is easiest for the guests to come to the aircraft factory. The planes taken by the guests can land directly at the airport. This time, the people from Cuba first arrived in the capital of the East, and then they were taken to the 320 factory by a special plane.

This is a regional airliner, MA 60, which is a civil aviation airliner modified on the basis of Y[-]. It is the most suitable propeller airliner for underdeveloped countries. Obviously, XAC also has ideas. It hopes to sell this airliner to Cuban customers. This time, it will be regarded as letting them experience flying.

The cabin door opened slowly, and a group of people came out, some were white, some were black, some were chocolate, but there were still more white people.

The leader is a white man in his 40s. He is not tall, but he has the unique aura of a soldier in every gesture.

"Hello, Mr. Pino, I have known you for a long time." Qin Tao went up to meet him, and stretched out his right hand: "I never thought that the Cuban Air Force would send you, a veteran who can recruit and fight well."

Rafael Del Pino belongs to the combat faction in the Cuban Air Force. In 73, Cuba began to intervene in the Angola civil war. A large number of Cuban pilots flew over Angola, fighting with the opponent’s phantom fleet. At that time, Pino was already the squadron leader of a MiG-21. Saved the patrol.Although Pino was dismissed because of this rescue, he became famous.

In 77, after returning to China, a MiG-21MF squadron commanded by Pino flew over Puerto Plata in the Dominican Republic and asked the country to release the previously detained Cuban merchant ship Capitán Leo.

Cuba didn't say anything else, and immediately sent planes to show off its force. If the other party didn't release the ship, they would bomb Puerto Plata and Santiago de los Caballeros the next day, so the other party compromised.

These things will surprise people, Cuba is so awesome?

That's right, in the previous era, Cuba was so awesome!They are definitely the number one leader in Latin America, and other countries have to go around. Even the United States suffered a loss in the Bay of Pigs, and they dare not easily provoke them in the future, let alone other countries.It’s good that Cuba doesn’t bully others. They are also walking sideways on the African continent. In Ethiopia, they beat the Somalis to the ground.

The Cuban Air Force is also quite powerful.In 90, the Cuban Air Force had 230 fighter jets and the most advanced MiG-29. Needless to say, this kind of combat power ranked first in Latin America, even if you look at the world, it is enough to be among the top.

However, the 90s were also their brightest time. With the collapse of the Red Empire, the Cuban Air Force lost its strongest backing. They simply had no strength to maintain a large fleet, and a large number of aircraft were put into storage or retired. For now, the total number of their aircraft has dropped to about [-], and they are all old aircraft. In the past ten years, they have never updated their fleet.

Even if they wanted to buy it, they couldn't find a suitable one in the international market, so they could only make do with it. This time, when they heard that Dongfang had advanced aircraft and invited them to visit, they were immediately tempted.

Pino came here in person, which was enough to see how much the Cubans valued him. At this time, looking at Qin Tao in front of him, Pino also admired him: "Mr. Qin, when the head of your starship company was detained in the United States, we also sweated a lot. We thought that unlucky guy would have to stay in the United States as a prisoner in the future. Unexpectedly, you rescued him in less than a month on the No. [-] ship. We admire you!"

Cuba has always been anti-American, and of course it admires anti-American heroes the most. What the Mingzhou Group did last time is definitely the most exciting thing for them. The Yankee plot failed, and the Yankee suffered a loss!

Mr. Qin is mighty!
"Those are what we should do. We have done nothing wrong, and of course we will not bow our heads under the pressure of the outside world."

"President Qin, you also produce advanced fourth-generation stealth aircraft, can we purchase that kind of fighter?" Pino continued to ask.

This sentence stunned the people behind Qin Tao.

What?Purchasing the fourth generation stealth machine?Aren't you here to purchase our L-15?

The big guy looked at Qin Tao suspiciously.

"Our fourth-generation stealth machine is expensive, and the unit price exceeds [-] million. I am afraid that you do not have enough funds to purchase it." Qin Tao said.

One sentence pushed the other party back.What is there in Cuba?cigar?brown sugar?Even if these things are famous all over the world, it is absolutely impossible to support the Cuban Air Force to purchase the most advanced stealth fighter.

A look of disappointment appeared on Pino's face.

"Besides, the order for our fourth-generation stealth aircraft has been scheduled for ten years. Even if you place an order now, you will have to wait ten years to get the fighter. Can you wait that long?"

Pino sighed: "What a pity."

When they received Dongfang's invitation, they came immediately. In fact, they came for the fourth-generation stealth machine. After they came, they realized that this machine could not be bought. Of course, their interest was greatly reduced.

"We have an aircraft that is most suitable for you. It can simulate many characteristics of the fourth-generation aircraft. In our country, it is actually used to train the pilots of the fourth-generation aircraft. You purchase this aircraft first, complete a full set of training on this aircraft, and have actual combat capabilities. When you have sufficient funds in the future, you can buy back the fourth-generation aircraft and directly form combat capabilities. Wouldn't it be better?"

"President Qin, you mean the trainer plane?"

"That's right, it's a trainer. Don't underestimate this kind of trainer. Its performance is not weak at all." Qin Tao said, "Let's go and have a look together?"

"Okay." Pino nodded. Although his interest had greatly diminished, he could only hold back his patience. Since he came, he couldn't turn around and go back. Let's have a look.

"Everyone, come to the stands, and our plane will give you a wonderful air show." Shi Lao greeted everyone.

It didn't rain today, which is really rare. Taking this opportunity, let the guests have a look at the performance of our own plane. Mr. Shi believes that after seeing these people, they will definitely be interested in the plane.

Everyone sat down, and the roar of the engine sounded in the distance. When they looked at the end of the runway, many people were stunned.

"The shape of that plane is very strange."

"That's right, isn't it just a trainer plane? Why does it have side wings?"

"Why is the engine so loud? Does it have two? Is this too extravagant for a trainer?"

In the surprised eyes of everyone, the plane completed the preparations before take-off, and when the brakes were released, the plane began to taxi quickly.

Quick, this is too fast, so fast that it is unbelievable!

Fifty, one hundred, one hundred and fifty!

The fighter plane had just slid 150 meters, and the front landing gear was raised!Now, everyone was not calm anymore, and stood up from their actions with a clatter.

"It's impossible!" Before Pino finished speaking, the rear landing gear was raised.

How far did you slide in total?
200 meters!
It is simply at the level of the propeller fighter era, and it can fly at 200 meters, which is unbelievable!
Even the MiG-29 can't do it, and the normal third-generation aircraft also need a runway of about 500 meters. The aircraft in front of them has completely subverted their cognition.

Qin Tao was also a little surprised. He was a shipbuilder, not an aircraft builder. Although Mingzhou Group owns the aviation industry, Qin Tao didn't know much about it. He never expected that the L-15 would take off so quickly.

It seemed that he knew what he was thinking, and the old Shi beside him said with emotion: "You are so powerful, Mr. Qin, thank you so much..."

Thank you Genghis Khan for the engine!
Even if it is improved from the technology of the Yak-130, the Yak-130 can't do it so fast, because the Yak-130 uses a non-afterburning engine, and the thrust is far less than that of the L-15. The only aircraft in the world that can do this kind of action is the plane in front of it!

When the afterburner is turned on, a single engine can provide 4.7 tons of thrust, and two engines can provide 9.4 tons. The normal take-off weight of the L-15 is only eight tons, and the thrust-to-weight ratio is close to 1.2. During the performance, the take-off weight is only 6.7 tons. This thrust-to-weight ratio not only exceeds 1.2, but also reaches the sky-defying 1.4. There is absolutely no second model in the world.Even with a maximum take-off weight of 11 tons, the performance of this fighter is still good.

Under the sky-defying thrust-to-weight ratio, the performance of the L-15 will of course be extremely good. Of course, this must also be matched with the advanced aerodynamic shape. If the shape design is not good, then it will not be able to exert the advantage of power.

At this time, before Shi Lao finished speaking, the Cubans cheered loudly.

I saw the nose of the beautiful plane rising, and the angle of attack was constantly expanding, thirty degrees, sixty degrees, ninety degrees?
Maybe there is no ninety degrees, that is, more than 80 degrees, but what it means to do this kind of action just after takeoff, the elites present all know: you are looking for death, if you do this, you will definitely stall and crash!

However, the plane in front of me did not stall. With the excellent performance brought by the side wings, it could pull the angle of attack to more than 80 degrees. With the thrust of the powerful engine, it pulled green onions on dry land and continued to accelerate upwards!
As long as the thrust-to-weight ratio exceeds 1, it has this ability, but in fact, many pilots dare not fly this kind of maneuver. Now, with a thrust-to-weight ratio of 1.4, pilots can play this maneuver with ease.

Just this one action conquered all Cubans.

Pino swallowed a mouthful of saliva: "If there is this plane, I dare to fight with F-16!"

When flying the MiG-21 before, Pino felt that the performance was too poor, and he could only run when he encountered the F-16, but if he had the plane in front of him, he would definitely not run again, and he must stay and fight!This mobility is definitely stronger than that of the MiG-29.

The plane climbed up to 500 meters, then turned off the afterburner, adjusted to the idle state, and the fighter plane began to decelerate upwards until the speed was zero. Then, the nose continued to be on the top, the tail was on the bottom, and the whole plane began to fall down.

"Tail thrust! This plane can actually perform a tail thrust, it's amazing!" Pino became excited. This maneuver tests the aircraft's high angle-of-attack performance and control performance. Ordinary aircraft can't do it at all, and even Pino has never flown this kind of maneuver.

The plane fell down tens of meters before leveling off, and then the whistling sound of the engine came again. It began to accelerate in the horizontal direction, followed by a horizontal circle, extreme climb, figure-eight circle, continuous roll, inverted flight, etc. The 8-minute flight performance fully demonstrated the performance of this plane.

The voices of the audience were also wave after wave, until the plane landed, everyone was still immersed in the flight performance just now.

"The maneuverability of this aircraft is a feast for our eyes. In our hands, only the MiG-29 can do similar maneuvers." Pino said: "We are very interested in this aircraft. Now, can we watch it up close?"

"Of course, you can still step into the cockpit to have a look."

This plane was originally intended to be sold to the outside world, and now these people are the first foreign customers, let alone looking at the plane, even if they want to disassemble the plane, we can agree.

So, everyone rushed to the tarmac in a swarm.

This is a two-seater trainer aircraft, but due to its small size and side wings, the pilots in the rear cockpit cannot enjoy the treatment of a separate gangway. The canopy is turned to the right, and a pedal is placed in the middle of the front and rear cockpit on the left.

This is just a small detail, but it also reflects the meticulousness of the designer.

When the two pilots came down, Pino climbed up without saying anything, and when he looked down at the cockpit, he sighed with emotion: "One level and three times?"

"Yes, this trainer aircraft is mainly used to train the pilots of the third-generation and fourth-generation aircraft. Of course, it needs a glass cockpit. After you buy it back, you can train pilots who can adapt to the new glass cockpit. Moreover, this method is convenient for human-machine interaction, and it is easier for pilots to maintain energy in the ever-changing air battle. Would you like to sit in and try?"

It was the first time for Pino to sit in the glass cockpit. Seeing that there was no instrument in front of him, and the switch panel was much less than before, he was even a little at a loss. How should this kind of plane fly?
"If you plan to purchase our fourth-generation stealth aircraft in the future, you must adapt to this method of operation. The cockpit interface is no different from our fourth-generation stealth aircraft, and the flight control laws are also very similar. When you change the flight, you will find that it can be seamlessly connected." Qin Tao continued to flicker.

Others were down below, touching various parts of the plane.

Over the years, the industry in the east has developed rapidly, and many aspects have moved closer to the west. The skin on the surface of the aircraft no longer has exposed rivets, and the surface is extremely smooth.

Some people touched the brake pads, and they saw that the plane stopped directly without a parachute. When they touched them, they were not hot at all. These are the most advanced composite brake pads!

More people looked at the engine.

"Is this engine produced by you yourself?"

"That's right, it was produced by Tianjiao Aviation in China. Compared with Lao Maozi's original AI-222 afterburning turbofan engine, its service life has been extended to [-] hours. After two overhauls, the engine's total service life is [-] hours. In this way, it only needs to replace the engine twice during the entire service life."

Change twice?
"The lifespan of this aircraft is [-] hours?" The Cuban was stunned.

The MiG aircraft they often use has a service life of only 1200 hours, and the MiG-29, a third-generation aircraft, has a body life of less than [-] hours.I just heard people here introduce that the lifespan of the engine is [-] hours, and I thought it had the same lifespan as the body, but I didn't expect the lifespan of the body to be [-] hours?

What is this concept?
At present, the most advanced F-22 has a lifespan of only [-] hours!
"Our airframe life is designed to be 1000 hours, but considering the life of the engine, it would be a waste to replace the engine at 29 hours, so it is temporarily limited to 7000 hours." Shi Lao said: "Our aircraft costs 29 million US dollars. Although it does not sound cheap, our lifespan is long. In its entire lifespan, it is equivalent to three brand new MiG-[-]s.

"Yes, you are quite right!"
