Chapter 328 Are you sure you can cruise at supersonic speed?
Gao Qiang's expression is very much like that of parents who send their children to compete and can't wait to know the results.
At this time, Mr. Rong said with a smile, "You two, Senior Engineer is the person in charge of the new engine project. His team is also the youngest team in our institute. They are very energetic and very powerful."
In fact, Li Hai did not despise Gao Qiang because of his youth. Since ten years ago, the average age of our country's military industry researchers has begun to decline significantly, becoming younger and younger. More and more young people with high technical levels are joining.
When they join the team, their vision becomes more expanded, their thinking becomes more unconstrained, and they become more motivated to attack higher and stronger.
Ten years ago, who would have thought that drones would shine on modern battlefields?
As for young people in China, some people proposed changes in the form of future air combat as early as thirty years ago, and even published an imaginary article on future air combat in the Air Force newspaper. In the article, the author believed that the form of future air combat will be based on a
A manned fighter jet commands several unmanned fighter jets to fight!
The article was published at the end of the last century, and the author was just an Air Force captain!
This article is a required reading text assigned to them by the chief teacher Li Zhan when Li Hai was a freshman.
Twenty or thirty years ago, China's young military officers were already aware of the impact of drones on future combat forms. Therefore, China's development and level of military drones have been at the forefront of the world. By the end of the first decade of the new century
, military drone technology begins to be transferred to the civilian drone industry...
Therefore, Li Hai had no doubt that Gao Qiang, who was a few years older than him, was the person in charge of the new engine project.
After sorting out his thoughts, Li Hai said straight to the point, "The acceleration was very strong, and I was not used to it for a while. The flight control system has also become more sensitive, and the nose pointing is very sensitive and clear..."
"Please focus on the engine and only talk about the bad aspects." Gao Qiang interrupted Li Hai and asked.
This guy has a habit of interrupting others, and this was the third time in less than two minutes.
But Li Hai didn't take it to heart. He nodded and said, "Okay. In my personal experience, the problem with this engine is that when accelerating hard, the power lags for two seconds. Yes, it is two seconds.
I just took a brief flight today, and this is the only feeling I have at the moment."
He said it very politely.
However, Gao Qiang is not an outsider. He knows very well the impact of a two-second lag. In an air battle, victory or defeat may be within one second, especially when you and I are competing for high-end technology in modern air combat.
In a battlefield environment.
Gao Qiang was stunned for a moment, then asked Mao Lele, "What do you think?"
Mao Lele was also stunned, pointed to his nose, and said with an embarrassed smile, "My biggest feeling is that the acceleration is too strong, and many movements are deformed. It has nothing to do with the engine, it's just that I haven't adapted yet."
He also spoke very politely.
In fact, the question raised by Mao Lele should represent most pilots. After all, there are only a few pilots like Li Hai who have great talent and blessings.
Of course, strong acceleration is a good thing, but if the flight control system cannot keep up, or there is a problem with the combination of the two, it will lead to a disconnect and the fighter aircraft will be difficult to control.
To put it bluntly, the car is powerful enough, but ordinary people cannot control it.
When Gao Qiang heard this, he turned to look at Luo Falcon and said, "Captain Luo, their opinions are the same as yours. There is lag in the power when accelerating hard, and the integration with the flight control system is low. Well, Mr. Rong, I'll go down there
Go back to the base and attack the enemy."
"Okay, hurry up. The test flight here starts today, and data will continue to come out in the future. Our project team must maintain progress with the test flight team." said Mr. Rong.
"Understood." Gao Qiang nodded, said hello to Li Hai and others and left.
Li Hai quickly said, "Senior Engineer, please wait a moment."
"Is there anything else?" Gao Qiang stood still and turned around.
Li Hai walked over and said, "I did not turn on the afterburner when flying at supersonic speeds. I wrote down some data."
As he spoke, he took out a palm-sized notepad from his pocket, flipped to the latest page, tore it off and handed it to Gao Qiang. What was recorded in it was the key data of the entire process of accelerating to breaking the sound barrier and the fuel consumption. This is very important to the project team.
Very important. Of course, these data can be calculated from background data, but they are not as accurate and intuitive as those recorded by the pilot.
"What did you say?" Luo Falcon came over and asked, "Did you fly at supersonic speeds without turning on afterburner?"
Li Hai nodded and said, "Yes, the characteristics of the newly modified engine are very similar to the engine used in Rafale M. It gave me the feeling that it has the potential for supersonic cruise, so I tried it, and the result was true."
"Brother, can we achieve supersonic speed without using afterburner?" Mao Lele's eyes almost popped out.
Who can fly at supersonic speed without using afterburners?
It can be said that except for the J-20A and F-22A pilots, the first action of other pilots before flying at supersonic speeds must be to turn on the engine afterburner.
Li Hai nodded once again with certainty.
At this time, Gao Qiang was in a daze and murmured to himself for a while, "My idea is right... The newly modified engine can allow the J-15 to achieve a certain level of supersonic cruise, so it can also allow the J-10 to achieve a certain level of supersonic cruise...
…”
His eyes suddenly lit up, and he shook the hands holding Li Hai excitedly, but as if he remembered something, he said to Mr. Rong, "Mr. Rong, what did I say! What did I say! Xin
Changing the engine can achieve supersonic cruise! No matter how many times I told them, they still don’t believe it!”
Mr. Rong was also surprised. He didn't believe it at first, but out of encouragement to the younger generation, he did not express his position, but let Gao Qiang proceed according to his ideas.
This is a major achievement.
Gao Qiang didn't think about anything else. He looked directly at Li Hai at this moment and looked at Li Hai with that look. He wanted to be as ambiguous as he wanted, and he liked him as much as he wanted. He spat and said, "Thank you! Thank you very much."
!Your bold attempt will let others know that there is nothing impossible, only unimaginable! Thank you very much! What do you call it?"
Only then did I remember that I didn’t know the name.
Li Hai smiled awkwardly, "Li Hai."
"Brother Li! If you need help in the future, just ask! For now, I have to leave quickly!"
After saying that, Gao Qiang left in a hurry and took the commuter car away.
There were still several people hanging out in the outfield, but he took the car and left alone. Li Hai didn't know whether to laugh or cry. This guy really has low emotional intelligence.
Gao Qiang's excitement made both Li Hai and Mao Lele deeply surprised. What had they experienced to have such an extreme reaction?
Mr. Rong said, "Senior Engineer's idea of improvement is different from that of most people. His purpose is not only to increase thrust and improve power response performance, but also to have a certain supersonic cruise capability. The institute decided to put him in charge because he wanted to
Let’s see what results this approach can produce.”
He smiled happily, "Now it seems that the results are rich and important."
"Mr. Rong, does the newly modified engine use WS-15 technology?" Li Hai asked.
He was curious. The only domestic aerospace engine capable of supersonic cruising is the WS-15.
Mr. Rong smiled and shook his head, "We and WS-15 are two different approaches."
"Thank you for clearing up the confusion." Li Hai said.
This will make Luo Xuan think about it and say, "Xiao Li, please tell me the process in detail."
Li Hai recounted the situation at that time, and finally said, "Although it takes a long time, it is definitely achievable. The next step is to add mounts and increase the take-off weight, which should be able to test the potential of the new engine step by step.
"
He smiled and said, "The fuel consumption data of the newly modified engine are very good."
As soon as these words came out, Mr. Rong smiled from ear to ear and said, "If Xiao Gao hears this, he will jump to the sky."
Fuel consumption data is very critical and is directly related to the range of the fighter aircraft, which determines the combat radius, airborne time, etc.
The biggest feature of the J-11 series fighter jets is their long range, known as long legs. Equipped with engines with lower fuel consumption, their range can exceed that of most tactical transport aircraft.
Everyone started chatting about the newly modified engine while waiting for the site staff to send a car over.
Ten minutes later, everyone returned to the accommodation area. They were all uniform two-story buildings, all in desert camouflage. Viewed from the air, all the buildings in this base blended in with the color of the ground.
"Lehi."
"arrive!"
Just as Li Hai was about to enter the dormitory, he heard Zhu Wei calling him from the corridor on the second floor.
"Come to my office." Zhu Wei said, turned and returned to the office.
Li Hai quickly ran to the spot.
In the dormitory building, Zhu Wei and Luo Xun have their own offices, which is standard for regiment-level cadres and is also a requirement of the experimental training project.
"Sit down and talk." Zhu Wei poured a glass of water for Li Hai and said straight to the point, "The J-15B can carry out supersonic cruise. Are you sure?"
Li Hai replied, "It's certain. Without afterburner, the maximum speed is 1,622 kilometers. At this speed, the speed remains unchanged. This is the final data. When converted, it equals Mach 1.3,
The international standard is that supersonic cruise is only considered above Mach 1.5."
Zhu Wei couldn't help but laugh and said, "Being able to fly at a speed of Mach 1.3 without using afterburner has surprised everyone."
After a pause, he nodded slightly and said, "Lao Luo and I have flown the J-15B for dozens of hours. No one would have thought of trying to fly at supersonic speeds without using afterburner. What a good boy, his thinking is very open-minded and his imagination is not limited.
.We are old!”
"Team leader, you are still young and not old at all." Li Hai said with a smile.
Zhu Wei waved his hand, obviously not following Li Hai's advice, and returned to the topic and asked, "The J-15B has a certain supersonic cruise capability. Do you know what this means?"
"Many, the combat capability of this fighter will be comprehensively improved, especially its maneuverability, airborne time, etc. When I was flying, I found that the sensitivity and clarity of the nose pointing are greatly improved compared to the A-type
Progress." Li Hai replied without hesitation that these changes are inevitable.
Unexpectedly, Zhu Wei shook his head slightly and said, "It's not just about tactics."
