Chapter 833: What is the concept of push-to-weight ratio 1.4?
320 Factory is a typical example of foreign trade. After developing K- that year, it successfully opened up the road to foreign trade and even exported the entire production line. However, after the development of L-5, the road to export was not
Tongchang, although it appeared at air shows several times, it was not sold.
The reason is also very simple: too expensive!
K-This kind of intermediate training aircraft is cheap, one costs several million, and even a production line is only about 100 million. Many countries can afford it, but the L-5 is different. This kind of aircraft sells for eight
With such a high price of one million US dollars, you can already buy second-hand MiG-29s and the like in the international arms market.
Therefore, even if many countries lack high-education aircraft, they are reluctant to purchase them. At present, only the domestic air force has purchased a batch. After all, the J-7 cannot simulate the various maneuvers of third-generation aircraft.
This is also the reason why they work hard to develop attack aircraft. Only by increasing its multi-tasking performance can they win the favor of users.
At this time, they were of course very excited when they heard that Qin Tao said that he would help them attract foreign customers.
"Thank you, Mr. Qin! As long as the customer is not very price sensitive, they will definitely choose our aircraft," Mr. Shi said excitedly.
This is enough to make everyone speechless. Our aircraft are brand new and can fly for thirty years, but customers always compare our aircraft with second-hand aircraft. Are our aircraft only worthy of competing with second-hand aircraft?
"Well, even if they are price-sensitive, we can still find a way." 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 talked about the next project with Mr. Qin.
The trainer aircraft currently used by carrier-based aircraft is the T-45 obtained by Dingo. The 320 Factory used its experience in K- to conduct some reverse mapping. Now this improved trainer aircraft is used by the Navy to train pilots.
The best trainer aircraft.
After the pilots have flown the carrier-based K-, they will fly the corresponding two-seat aircraft. Of course, there is also an advanced trainer aircraft in between. They also have to do a lot of training on the basis of the two-seat carrier-based aircraft.
training, a waste of time and money.
With the foundation of the carrier-based version of K-, everyone is confident in the improvement of the carrier-based version of the L-5. However, 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 attack aircraft.
"Of course. 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 need such an advanced trainer aircraft, and it can also
When used as attack aircraft, the training aircraft carried by our naval aircraft carriers can also be used as attack aircraft when needed, especially in front of some weak opponents. We do not need to dispatch the J-15 or J-32.
It’s enough to fly over.”
Everyone was overjoyed: "Okay, Mr. Qin, when the mission of this attack aircraft is completed, we will modify the carrier-based trainer aircraft!"
It is indeed very important for the L-5 to have the ability to board ships. After all, this trainer aircraft has advanced performance and can save the flight life of precious two-seat fighter jets. We cannot let the J-15 and J-32 sit in squat landing gear.
It's a waste of precious life. Besides, the engine used by this trainer aircraft is from Genghis Khan. Expanding the user range of this aircraft will also be beneficial to Genjiao Airlines.
Moreover, this kind of aircraft uses sub-costal air intake, and the front landing gear is also connected to the girder. This way, it can not only land but also take off using a catapult. It only needs to be strengthened. The L-5 is inherently capable of boarding ships.
.
"Mr. Qin, we have another idea." The big guy kept up his efforts.
"What idea"
"We want to modify the appearance of this trainer aircraft so that it has certain stealth capabilities."
Stealth is a trend. Look at the fourth-generation aircraft of the Mingzhou Group. They are selling like hotcakes because of their stealth capabilities. They also want to equip their training aircraft with stealth capabilities so that they can perform attack missions more smoothly.
"The nose and air intake are easy to modify. Just improve them according to the standards of the American F-fighter. The main thing is the vertical tail. We have to change the single vertical tail into two cambered double vertical tails. This workload is quite heavy.
It's big, but we should be able to complete it. Applying another layer of stealth paint can reduce the radar reflection area of our fighter planes by an order of magnitude, making it easier to perform attack missions."
Qin Tao smiled: "You can make up for this improvement yourself, I won't say anything else."
If the l-5 sells well, they can raise their own funds to make stealth modifications. If they don't sell, they won't be able to raise funds for improvements.
So, it still depends on them.
In Qin Tao's time and space, L-5 said that it would improve its invisibility, but there was no movement, and it was not even as fast as Xiaolong. Therefore, Qin Tao didn't know whether this improvement could be achieved. He
I won't make any comments.
Qin Tao inspected the 320 factory for two days, and on the third day, customers came to visit.
"Mr. Qin, guests from Cuba are here." Xu Zhengyang said to Qin Tao.
"Well, let's go, let's go to the runway to meet you."
It is easiest for guests to come to the aircraft factory. The plane they take can land directly at the airport. This time the people from Cuba first arrived in the capital of the East, and then a special plane took them to Factory 320.
This is a regional airliner, the MA-60, which is a civil aviation airliner modified on the basis of the Yun-7. It is the most suitable propeller airliner for underdeveloped countries. Obviously, XAC also has ideas and hopes to sell this kind of airliner.
For Cuban customers, this time it’s like letting them experience flying.
The cabin door slowly opened, and a group of people came down, some were white, some were black, and some were chocolate, but there were still more white ones.
The leader was a white man in his forties. He was not tall, but he carried a unique military aura in his movements.
"Hello, Mr. Pino, I have long admired your name." Qin Tao came up to greet you and extended his right hand: "I didn't expect the Cuban Air Force to send you such a veteran who is good at fighting."
Rafael Del Pino was a combatant in the Cuban Air Force. In 1973, Cuba began to intervene in the Angolan civil war. A large number of Cuban pilots flew over Angola and fought with the opponent's Phantom fleet. At that time, Pino was already a fighter.
A MiG-2 squadron was formed. When a Cuban patrol was surrounded, Pino took the initiative and flew the MiG-2 over the enemy's head repeatedly at ultra-low altitude. When the enemy lowered his head to find a bunker, the Mi-2
The helicopter successfully rescued the patrol. Although Pino was relieved of his duties as a result of the rescue, he became famous.
In 1977, after returning to China, a MiG-2MF squadron commanded by Pino flew over Puerto Plata in the Dominican Republic, demanding that the country release the previously seized Cuban merchant ship Capitanleo. This merchant ship was originally intended to support Angola, but accidentally entered
It entered Dominican waters and was seized by others.
Cuba did not hesitate and immediately sent planes over to show off its force. If the other party did not release the ship, they would bomb Puerto Plata and Santiago de los Caballeros the next day. Therefore, the other party compromised.
These things will surprise people, Cuba is so awesome
Yes, in the past, Cuba was so awesome! They are definitely the number one hegemon in Latin America, and other countries have to go around. Even the United States suffered a loss at the Bay of Pigs, and they will not dare to provoke them easily in the future, let alone other countries.
It’s a good country. It’s good if Cuba doesn’t bully others. They are also walking sideways on the African continent. In Ethiopia, they beat the Somalis until they peed.
The Cuban Air Force is also quite powerful. In the 1990s, 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.
Be among the best.
However, 1990 was also the time when they were at their most glorious. With the collapse of the Red Empire, the Cuban Air Force lost its strongest backing. They simply did not have the strength to maintain a huge fleet. A large number of aircraft were transferred to inventory or retired. At present,
Generally speaking, their total number of aircraft has dropped to about a hundred, and they are all old aircraft. They have not updated their fleet in the past ten years.
Even if they wanted to buy one, they couldn't find a suitable one in the international market, so they had to 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 person in charge of your Starship Company was detained in the United States,
, we were also sweating, thinking that the unlucky guy would have to stay in the United States as a prisoner from now on. Unexpectedly, you only used the No. 4 ship in less than a month to rescue him. It's amazing, we admire him!
"
Cuba has always been anti-American, and of course they admire anti-American heroes the most. What the Mingzhou Group did last time was definitely the most exciting thing for them. The Yankee conspiracy did not succeed, and the Yankees suffered a loss!
President Qin is mighty!
"Those are what we should do. We are not wrong, and of course we will not bow under external pressure."
"Mr. 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 following Qin Tao.
Why are you purchasing a fourth-generation stealth machine? Aren’t you here to purchase our L-5?
Everyone looked at Qin Tao with doubtful eyes.
"Our fourth-generation stealth aircraft is expensive, with a unit price of over 100 million. I'm afraid you don't have enough funds to purchase it," Qin Tao said.
Just one sentence pushed the opponent back. Even if Cuba was famous around the world for its cigars, brown sugar and other things, it would never be possible for the Cuban Air Force to purchase the most advanced stealth fighter jets.
A disappointed look appeared on Pino's face.
"Moreover, the order for our fourth-generation stealth aircraft has been scheduled for ten years. Even if you place the order now, it will take ten years before you can get the fighter jet. Can you wait that long?"
Pino sighed: "What a shame."
After receiving the invitation from Dongfang, they came immediately. In fact, they came for the fourth-generation stealth aircraft. After arriving, they found out that they could not buy it, and of course their interest was greatly reduced.
"We have an aircraft here that is most suitable for you. It can simulate many characteristics of fourth-generation aircraft. In our country, it is actually used to train pilots of fourth-generation aircraft. You will purchase this aircraft first. In this
Complete a full set of training on the 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 effectiveness. Wouldn't it be better?"
"Mr. Qin, you mean the training aircraft?"
"That's right, it's a training aircraft. Don't underestimate this kind of training aircraft. Its performance is not weak at all." Qin Tao said, "Let's go and take a look."
"Okay." Pino nodded. Although his interest had greatly diminished, he could only suppress his patience. Now that he was here, he couldn't turn around and go back. Let's take a look before talking.
"Everyone, come to the stands. Next, our plane will give you a wonderful flight show." Mr. Shi greeted everyone.
It didn't rain today, which is really rare. I took this opportunity to let the guests see the performance of our aircraft. Mr. Shi believed that these people would be interested in the aircraft after seeing it.
As everyone sat down, the roar of engines sounded in the distance. When they looked towards the end of the runway, many people were stunned.
This chapter is not over yet, please click on the next page to continue reading the exciting content! "The shape of that plane is very strange."
"Yes, isn't it just a training plane? Why does it have side wings?"
"Why is the sound of the engine so loud? There are two of them. Isn't this too luxurious for a training aircraft?"
As everyone watched in surprise, the plane completed its preparations for takeoff. When the brakes were released, the plane began to roll away quickly.
Fast, this is too fast, unbelievably fast!
Fifty, one hundred, one hundred and five!
The fighter plane had just taxied 150 meters when the nose landing gear was raised! At this time, everyone was not calm anymore and stood up from their seats with a clatter.
"This is impossible!" Before Pino could finish his words, the rear landing gear was actually raised.
How far did it slide in total?
Two hundred meters!
It is simply the level of the propeller fighter era. It can fly only 200 meters. This is simply unbelievable!
Even the MiG-29 can't do it. A normal third-generation aircraft also needs a runway of about 500 meters. The aircraft in front of them simply subverted their understanding.
Qin Tao was also a little surprised. He was a shipbuilder, not an aircraft manufacturer. Although Mingzhou Group had an aviation industry, Qin Tao didn't know much about it. He never expected that the L-5 could take off so quickly.
As if he knew what he was thinking, Mr. Shi on the side said with emotion: "Strong enough to fly bricks, Mr. Qin, thank you so much..."
Thank you Tianjiao Airlines for the engine!
Even if it is improved from the technology of the Yak-30, the Yak-30 cannot be so fast, because the Yak-30 uses a non-afterburning engine, and the thrust is far less than that of the L-5. The whole world can do this.
The only thing that can move is the plane in front of us!
When the afterburner is turned on, a single engine can provide 4.7 tons of thrust, two engines are 9.4 tons, and the normal take-off weight of the L-5 is only eight tons, and the thrust-to-weight ratio with afterburner turned on is close to .2, show
At that time, the take-off weight was only 6.7 tons. The thrust-to-weight ratio not only exceeded .2, but also reached an incredible .4. There is absolutely no second model in the world. Even if it has a maximum take-off weight of tons, this
The performance of this fighter jet is still good.
Under the unfavorable thrust-to-weight ratio, the performance of the L-5 will of course be extremely excellent. 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 its power advantage.
At this time, before Mr. Shi had finished speaking, the Cubans cheered loudly.
I saw the nose of the beautiful aircraft rising, and the angle of attack continued to expand, thirty degrees, sixty degrees, ninety degrees
Maybe there is not 90 degrees, which is more than 80 degrees, but what does it mean to do this kind of action just after taking off? The elites present all know: you are looking for death, if you do this, you will definitely stall and crash!
However, the aircraft in front of me did not stall. It relied on the excellent performance brought by the side wings to increase the angle of attack to more than 80 degrees. It relied on the thrust of the powerful engine to pull onions from dry land and continue to accelerate upward!
As long as the thrust-to-weight ratio exceeds, it will have this ability, but in fact many pilots dare not fly this maneuver. Now, with a thrust-to-weight ratio of .4, pilots can perform this maneuver with ease.
Just this one action conquered all Cubans.
Pino swallowed: "If there is this plane, I dare to fight with the F-6!"
When flying MiG-2 in the past, Pino felt that the performance was too poor and he could only run when encountering an F-6. But if there was an aircraft in front of him, he would definitely not run again and would definitely stay and fight! This maneuver
It's definitely more powerful than the MiG-29.
The aircraft climbed up to 500 meters, then turned off the afterburner and adjusted to the idle state. The fighter began to decelerate upward until the speed was zero. Then, the nose continued to be above and the tail was below, and the entire aircraft began to fall downward.
"Tail thrust! This aircraft can actually perform tail thrust. It's amazing!" Pino became excited. This action tests the performance and control performance of the aircraft at large angles of attack. Ordinary aircraft cannot do it at all. Even Pino
I have never flown this kind of maneuver before.
The plane fell down for tens of meters before leveling out. Then the roar of the engine was heard again. It began to accelerate in the horizontal direction, followed by horizontal circling, rapid climb, vertical circling, continuous roll, inverted flight, etc.
, the fifteen-minute flight performance fully demonstrated the performance of this aircraft.
The audience's voices grew louder and louder, and until the plane landed, everyone was still immersed in the flight performance.
"We are really impressed by the maneuverability of this aircraft. Currently, only the MiG-29 can do some similar maneuvers in our hands." Pino said: "We are very interested in this aircraft. Now, we can get it at close range.
Watch it?”
"Of course, you can get on the cockpit and have a look."
This aircraft was originally meant to be sold to the outside world, but now these people are the first foreign customers. Not to mention viewing the aircraft, even if they want to dismantle the aircraft, we can agree.
So, everyone swarmed towards the tarmac.
This is a two-seat training aircraft, but due to the small size of the body and the side wings, the pilot in the rear cockpit does not enjoy the treatment of a separate gangway. The canopy is flipped to the right, and the left side is forward and backward.
A pedal was placed in the middle of the cockpit, and a tall handrail was added to the right side of the gangway in the front cockpit. This way, the pilot could step on the pedal and hold on to the handrail to get up and down the gangway in the front cabin.
This is just a small detail, but it also reflects the designer's meticulousness.
When the two pilots came down, Pino had already climbed up before saying anything. When he looked down at the cockpit, he sighed: "One level and three times."
"Yes, this trainer aircraft is mainly used to train pilots for third-generation and fourth-generation aircraft. Of course, it needs a glass cockpit. After you purchase it, you can train pilots who are adapted to the new glass cockpit. Moreover, in this way, man-machine
The interaction is convenient, and it is easier for pilots to maintain their energy in the ever-changing air battle. You can try it out."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! It was the first time for Pino to sit in the glass cockpit. There were no instruments in front of him, and the switch panel was much smaller than before. He was even a little at a loss.
Okay, how should I fly this kind of plane?
"If you plan to purchase our fourth-generation stealth aircraft in the future, you must adapt to this operation method. The cockpit interface is no different from our fourth-generation stealth aircraft, and the flight control laws are also very similar. When you change flight,
You will find that it can be seamlessly connected." Qin Tao continued to lie.
Others were down below, touching various parts of the plane.
Over the years, the industry in the East has developed rapidly and has moved closer to the West in many aspects. There are no longer exposed rivets on the skin of the aircraft, and the surface is extremely smooth.
Someone went to touch the brake pads, and they saw that the plane stopped directly without releasing the drag chute. When they touched it, they were not hot at all. These are the most advanced composite brake pads!
More people looked at the engine.
"Do you produce this engine yourself?"
"Yes, it is produced by our domestic Tianjiao Aviation. Compared with Lao Maozi's original ai-222 afterburning turbofan engine, its service life has been extended to one thousand hours. After two overhauls, the total engine life has been three thousand hours.
In this way, it only needs to replace the engine twice during its entire life."
Change twice
"The lifespan of this aircraft is nine thousand hours," the Cubans were shocked.
The MiG aircraft they often use has a service life of only 200 hours. The MiG-29, a third-generation aircraft, has a body life of less than 3,000 hours. I just heard someone here introduce that the engine has a lifespan of 3,000 hours. I thought it was
The body has the same lifespan. I didn’t expect that the body actually has a lifespan of 9,000 hours.
what is this concept
The current most advanced F-22 has a body life of only 10,000 hours!
"Our airframe life is designed to be 10,000 hours, but considering the engine life, it would be a waste to replace the engine at 9,000 hours, so it is temporarily limited to 9,000 hours." Shi Lao said: "Ours
An aircraft sells for 10 million U.S. dollars. Although it sounds not cheap, our service life is long. In its entire life, it is equivalent to three brand-new MiG-29s, which cost 60 to 70 million U.S. dollars.
If you consider the price of replacing an engine for a MiG-29, it would be hundreds of millions."
