Chapter 138 The chain reaction caused by the turbojet 14 (Part 1)
Actually, this is not the new turbojet 14 actually installed on the No. 04 prototype, but an old engine set What the new receiver looks like.
Specially designed to be displayed at air shows for people to see.
It's not that I'm afraid of leaks - after all, you can't see what the core structures of the high-pressure compressor and turbine look like from the outside.
And if the aviation design can be copied at a casual glance, then Chang Haonan may not get the chance to show off his skills from the beginning.
Our country has a physical copy of the Soviet Union's last turbojet R29-300. The J-10's initial target power was the turbojet 15 that imitated this thing. It was so easy to copy it.
The main reason is that Factory 410 has built a total of 6 new engines so far, all of which are installed on three prototypes...
Except for a few people such as Chang Haonan , and no one knows this secret.
So, when the "true face" of the Turbojet 14 was revealed from under the tarpaulin, there was still a sound of admiration or cheers all around.
In the 1990s, putting a real aero engine on display like this was not very common even at foreign air shows.
It is an unprecedented first time in the country.
This is even the first time for many people to see what a separate axial-flow turbojet engine looks like.
Looking at the densely packed complex pipelines on the surface of the casing and the neatly arranged layers of low-pressure compressor blades, everyone felt basically confused.
Although I can’t understand it, it’s so complicated, so precise, and I like it...
In short, if there weren’t security personnel with loaded guns watching, I’m afraid someone would have rushed up and hugged me on the spot. lick.
As a decent person, Xi Boyang did not keep staring at the aviation engine, but quickly paid attention to the specific content on the display board.
Then, he showed a shocked expression of "Are you kidding me?"
"The maximum afterburner thrust is 7500kg, the intermediate thrust is 4930kg..."
"The total boost ratio is greater than 18?"
"The total engine weight is less than 1100kg?"< br>
"The first turnover period is not less than 150h?"
"Holy shit... is this data serious? How do I remember that the design target of the turbojet 14 was only 7 tons of thrust?"
If mood could be embodied through symbols, Xi Boyang felt that his head should be full of question marks right now.
"Teacher Xi, this data... is amazing?"
Someone next to him couldn't help but ask.
After all, not everyone knows so much about aviation power.
"It's more than amazing..."
Xi Boyang subconsciously wanted to lift the camera, but then remembered that the film had run out, so he had no choice but to put it down again, and explained to the person next to him:
“If you don’t look at the inherent shortcomings of turbojet engines such as fuel consumption and lifespan, the performance is almost the same as the F404 turbofan engine newly developed by the Americans in the 1980s.”
After him With such a comparison, more people can understand.
"F404...is the one used on the F18?"
"That's right."
"So if you calculate it this way, the performance of this J-8C is about the same as that of the F18?"
"That's not an analogy...but in short, in terms of aviation development level, it is not an exaggeration to directly jump 20 years compared to the past."
"..." Not far from Xi Boyang There, two people with media badges were looking at the fighter jet that had just stopped in front of them with complicated expressions.
"Brother Liu, I knew you were joking with me last night, so..."
"No, I didn't..."
Brother Liu really wanted to It was just a wild guess that I was saying, and I had absolutely no intention of hiding anything.
But even he himself found it unconvincing.
"Forget it, don't be stunned, hurry up and take pictures. I'll teach you how to write when you get back."
"By the way, remember to check what's going on with the Americans' F18s. I thought I heard someone just now It is said to be similar to this.”
……
Since most tourists are crowded near the exhibition area of China Aviation Industry, and more people are still stuck on the road. The rest of the venue seemed a bit deserted.
Inside the Russian exhibitor's exhibition hall, a tall and thin gray-haired middle-aged man looked at the dense crowd not far away and asked the people next to him:
"The plane that was performing the flight just now is the new model that Artyom and the others reported before, right?"
It is Mikhail Pogosyan who is gradually taking over the baton of Sukhoi Company. .
"Yes, they named it J-8C. It sounds like it is an improved version of the simple enlarged version of the MiG-21."
"No, Alyosha, from that aircraft There is no trace of MiG-21 on it.”
Pogosian shook his head:
"As for the naming... I think it is just a cover-up during the research and development process, just like our original Figure 22M."
"You mean, they are trying to deceive the Americans?
There is no technical connection between Figure 22M and Figure 22. The name was changed just to avoid treaty restrictions.
Obviously, in Pogosian’s view, this aircraft is called J-8C. The plane is probably the same.
“I can’t say for sure, but I know that about ten years ago, the Chinese were tricked by the Americans on this plane before they came to find us. ”
Pogosian shrugged.
The man called Alyosha is actually Alexei Bulatov. He is not actually Sukhoi Company, but a senior engineer of the Rulika Design Bureau.
He lowered his head and hesitated for a moment, as if he was reminiscing about the flight show just now:
"Misha, after our performance is over, I am going to go to the Chinese exhibition area. Take a look. "
"The vertical maneuverability of the aircraft just now, especially the climb rate, is very good. I think it is at least better than the MiG 23ML. It may be due to the replacement of new power."
The turbojet 13 that China has widely used in the past is still essentially an improved version of the R11F-300. Although Bulatov is a senior engineer at Ryulika, he does not know much about the products of his peer and competitor Tumansky Design Bureau. Strange, it is clear where the limits of this engine are.
"Well...new planes, new engines, they seem to have suddenly enlightened in the past year..."
Pogosian rubbed his forehead in confusion. Brow:
"It seems that Mikhail Petrovich is right. Fortunately, we did not delay it any longer. After the funds are in place, the new Su-27 improved model must be put on the agenda. ”
“Compared to this, I think finding new customers is the most important. Judging from China’s development speed, they may not buy complete machines from you soon.”
Bulatov takes a longer view.
"You are right, but fortunately not all countries are like them..."
Still adding more for flankerr's reward.
