He started using the L-15 as a training aircraft, and now he is flying the J-10a1... Lin Mo glanced at the J-10b on the tarmac in the distance and said, "It's the previous version of the J-10b." "Oh, really?"
What a coincidence. The J-10 is a project of our 611 Institute. I was also a member of the project team at the time. This aircraft cost a lot of money. Although the framework is now set up, there is still a long way to go.
The engine, the body structure..." When talking about the airplane, Uncle Yan didn't even bother to eat, he kept talking to Lin Mo as if there were endless waves.
“It would be great if the engine could have two engines, and it would be perfect if its service life was longer.
"Lin Mo said some of his feelings about using it.
"There is no way. The engine is originally one of the symbols of a country's industry. Aviation engines have extremely high requirements for materials and processing precision. Originally, the J-10 was planned to use domestically produced engines, but there is still a certain distance between them and Russian and American products.
Only the early batch of J-10s used the Taihang-2 engine, which may have something to do with the processing technology. The low-speed acceleration was a bit slow, the sound was heavy, and the lifespan was not satisfactory. Later, they all used Lao Maozi's al-31fn. The new version of the vector engine is still
Yes, it is even used on the Su-27, but the first overhaul time is only 1500 hours. It is estimated that the life of the subsequent batches of al-31fn will be better and can reach 2000 hours. Each al-31fn was just sold to us.
The price is US$3 million, accounting for 20% of the total cost of the aircraft. An aircraft must be equipped with one engine and one engine. Two engines can ensure the use of an aircraft. However, compared with the PE of the American F-16
After decades of professional knowledge, technical terms popped out of his mouth one after another. If it were an ordinary person, his eyes would be wide open and his face would be confused.
Only Lin Mo, who once participated in the assembly of the J-10, could sit on the sidelines and listen with interest.
Generally, the service life of an engine is only ten years. Although the driving force of dual-engine engines has been significantly improved, the speed is still the same, and the cost is even higher. Domestic fighters cannot invest hundreds of billions of dollars in development costs like the old and American ones. I'm afraid
Even if all the fighter jets in China were packaged and sold, it would not be enough to cover the development cost of a D-35.
Lin Mo listened to Uncle Yan, the former aircraft design expert from the 611 Institute, talking non-stop. He was indeed one of the experts in the original J-10 R&D team. He was really not bragging. Although it was all public data and information, it did not involve military secrets.
, but in terms of familiarity with the J-10, ten Lin Mo can't catch up. Even if they can fully analyze the gold coins, they can only understand it, but cannot fully understand every function.
Taking advantage of this opportunity, Lin Mo bravely told Uncle Yan some of his ideas for modifying the J-10.
"Young man, you are so courageous. Self-modification will have to go to a military court. It is a fighter jet that the country spent hundreds of millions of dollars to build. How can you change it just by asking for it?" Uncle Yan said with eyes.
Staring wide, as if he had met Lin Mo all over again, he looked up and down, shook his head and said: "Fighters are no better than civilian aircraft. How can they be so easy to change? I have considered the ideas you mentioned before, although
That's right, but the cost and workmanship have always failed to meet the requirements. If it could have been achieved, it would have been entrusted to the manufacturer for production. You little guy, you don't really have to change it like this. You know, if a component fails, it will destroy the machine.
People will die." A fighter pilot talked to him, an old expert, about aircraft modifications, and he spoke so eloquently that it made him feel dumbfounded. No matter how experienced the old pilot was, he could still troubleshoot the queuing faults, but when it came to the various aspects of the aircraft,
The understanding of the structure and modules is a manufacturing engineer who can't catch up with the plane even though he is trying to catch up. This is a job made out of nothing. It is not as simple as just replacing something that is broken.
"Hey, I only use my own J-10A for my own use. I have enough authority to make reasonable improvements, and I have already changed some of them, including the telex system, control system and program. Looking at it now, there are basically no problems.
I had some solo training with the J-10B a while ago...but the words coming out of Lin Mo's mouth made Uncle Yan's heart stop.
Sure enough, a newborn calf is not afraid of tigers, so he dares to kill him like this.
"What's the result?" Uncle Yan held Lin Mo's hand tightly. This kind of improvement can also be directly applied in actual combat. People who don't have much courage dare not do this kind of experiment. You must know that during the test flight, they all use
People's lives are at stake, there is no 100% certainty, and every little bit of improvement is a matter of life and death.
"The maneuverability index has been increased by 5%, the stability has been improved, and the vector propulsion has been increased by 3%. It can basically be tied with the Fiber-10b, but any further changes will involve the aerodynamic layout. Lin Mo said the improved performance parameters
When he came out, he attracted a strange look from Uncle Yan. Without professional equipment, how did Lin Mo get this data? According to him, the environment he was in was almost as good as a small research institute.
Modifying the aerodynamic layout is a matter of modifying the appearance of the aircraft. Small changes are the difference between the small version of abcd, and major changes are changes to the complete version. It is not that easy to change. You need to consider the impact of various atmospheric environments and tactical actions.
.
"Really? You're not lying to me, old man, are you?" Uncle Yan expressed doubts, but the improvements, parameters and actual data that Lin Mo talked about didn't seem to be fake, but he suddenly became alert, this young man wouldn't
He must be a spy, but he actually knows so much. Ordinary pilots cannot master such detailed professional knowledge.
"Of course it's true. I modified it myself." Lin Mo shrugged. Every technology and every part surrounding the aircraft originally has a high technical level and is not accessible to ordinary people.
"Then let me test you." Uncle Yan reported a few parameters and equipment names. After speaking, he looked at Lin Mo proudly and said, "If you can tell which part these parameters are on, what are they?"
I will tell you several J-10 modification plans that I know, otherwise, you won’t be able to get any good things from me." He confidently picked up the lunch box that Lin Mo brought him, and he recognized this
It was not easy for the young man to answer. While he was thinking about it, he could have some hot meal in peace.
Before picking up the first piece of rice with chopsticks and before putting it into his mouth, Lin Mo's "answer" shocked Uncle Yan. It was as if this young man had assembled a complete J-10 with his own hands. He had just
Among the parameters and equipment names reported, some are even non-detachable one-time firmware with special confidentiality settings. If you try to disassemble it, it will be destroyed immediately. Only those who have seen it with their own eyes know the secrets, and those who have access to it will know the secrets.
People must be people with special permissions.
Uncle Yan's guess was almost infinitely close to the truth. Lin Mo had assembled a J-10 himself, but there was still a certain gap between the technical level of manufacturing the J-10. However, the set of assembly information was indeed very high.
If it were not for the sake of the "Dark Night" Special Service Brigade, such information would never have fallen into Lin Mo's hands.
It is impossible for spies to obtain this kind of information. If they can obtain this kind of information, they are basically very close to obtaining the complete J-10 blueprints. Why do they need to spend so much effort to obtain this kind of information from a degraded personnel like him?
Keep secrets in your mouth.
"You are not a test pilot, are you?" Uncle Yan suppressed the shock in his heart. What kind of pilot is this? He is almost catching up with the aircraft designers. Can ordinary pilots master so much professional knowledge of aircraft structure?
"Of course not, the confidentiality level of my unit is very high, it may be higher than your 611 level." Lin Mo spread his hands and explained that what he and Uncle Yan were talking about already involved high confidentiality.
.
However, both of them had reservations. They only involved semi-public information that was higher than private public information but could also be investigated by foreign situation departments. Uncle Yan hit the nail on the head and pointed out that only the real information about the semi-public information was
Only insiders know such details.
"Haha - okay, okay, I believe you, but I can't say too much in this public place. It's time for me to shut up. Young man, let me show you some of my own thoughts. Of course, these have been eliminated several years ago.
The lost plan has passed the confidentiality period." Uncle Yan put down his lunch box, flipped back a few pages of the album on his tui, and handed it to Lin Mo.
"Said, the aerodynamic layout of a fighter jet is actually not difficult. What is often limited is the pilot, as well as the limitations of materials and processing technology. In fact, there is no perfect aircraft design, but the human body cannot bear it and can exert all its capabilities.
The maneuverability of the body's performance and the material processing technology cannot achieve such a production cost. Sometimes, small-scale prototype production is possible, but if it is mass-produced, the cost and manufacturing production will not be able to bear such a high price, so it is not
There is the most perfect design, and there is only the most suitable design. You take a look first, I have to eat first." Uncle Yan thrust the album into Lin Mo's hand, picked up the lunch box again, and ate the young man's meal with relish.
The pilot's lunch was indeed a high-quality meal carefully prepared for the staff, which was much better than his two pieces of dry bread.
"Good stuff 1" Lin Mo was chewing on the apple given by Uncle Yan in his hand while looking through the album with bright eyes.
As Uncle Yan said, manned fighter jets can never compare to drones in terms of perfect aerodynamic design due to considerations of the driver’s physical endurance and line of sight!
