Chapter 138 The chain reaction caused by turbojet 14 (Part 1)
In fact, this is not the new turbojet 14 actually installed on the No. 04 prototype, but an old engine put on a new casing.
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.
Moreover, if aviation design can be copied at a glance, then Chang Haonan may not get the chance to show off his skills from the beginning.
Our country has a physical version of the Soviet Union's last turbojet R29-300. The initial target of the J-10 was to imitate the turbojet 15. If it was so easy to copy, it would have been copied a long time ago.
Mainly because Factory 410 has built a total of 6 new engines so far, all of which are installed on three prototypes...
It's just that no one knows this secret except Chang Haonan and a few other people.
So, when the "true face" of the Turbojet 14 was revealed from under the rainproof cloth, there was still a sound of admiration or cheers all around.
In the 1990s, it was not very common to display a real aircraft engine like this even at foreign air shows.
This is an unprecedented first time in China.
It is even the first time for many people to see what a single axial flow turbojet engine looks like.
Looking at the densely packed and 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 love it…
In short, if there were not security personnel with live ammunition watching, I am afraid someone would have rushed up to hug and lick me on the spot.
As a decent person, Xi Boyang did not keep staring at the Taiwan Airlines, 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?”
“The first turning period is not less than 150h?”
“Holy shit…is this data serious? Why did I remember that I said before that the design target of the turbojet 14 was only 7 tons of thrust?”
If mood can be embodied through symbols, Xi Boyang feels that his head should be full of question marks now.
“Teacher Xi, this data is... very impressive?”
Someone next to me couldn't help but ask.
After all, not everyone understands aviation power so deeply.
“More than just awesome…”
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 his comparison, more people can understand.
“F404…is the one used on 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 say that it has jumped 20 years compared to the past.”
“…” Not far from Xi Boyang, 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 say that I was really just guessing, and I had no intention of hiding anything.
But even he himself found it unconvincing.
“Forget it, don't be stunned, hurry up and take pictures, I will teach you how to write a manuscript when you get back.”
“By the way, remember to check the condition of the American F18. I thought I heard someone say it is similar to this.”
Since most tourists were crowded near the China Aviation Industry exhibition area, and more people were still stuck on the road, other parts of the venue seemed a bit deserted.
Inside the Russian exhibitor's exhibition hall, a tall, slender, 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 a simple enlarged version of the MiG-21.”
“No, Alyosha, there is no trace of the MiG-21 on that plane.”
Pogosian shook his head:
“As for the naming... I think it's just a cover-up during the research and development process, just like our original Figure 22M.”
“You mean they are trying to deceive Americans?
There is no technical connection between Figure 22M and Figure 22. The name was changed just to avoid treaty restrictions.
Obviously in Bogosian's opinion, this aircraft called J-8C is probably similar.
"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 named 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 recalling the flight performance just now:
“Misha, after our performance is over, I plan to go to the Chinese exhibition area to 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.
“Hmm…new aircraft, new engines, why have they suddenly become enlightened in the past year…”
Pogosian rubbed his brow in confusion:
"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 version must be put on the agenda."
“Compared to this, I think finding new customers is the most important thing. Judging from China's development speed, they may not buy complete machines from you soon.”
Bratov takes a longer-term view.
“You are right, but fortunately not all countries are like them...”
Or I'm adding more updates for flankerr's reward.
