Chapter 138 Chain reaction caused by turbojet 14 (Part )

In fact, this is not the new turbojet 04 actually installed on the No. 14 prototype, but an old engine put on a new receiver.

It is 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 the aviation design can be copied at a casual glance, then Chang Haonan may not get the chance to show his strength 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...

It's just that no one knows this secret except Chang Haonan and a few others.

Therefore, when the "true appearance" of the Turbojet 14 was revealed from under the tarpaulin, there was still a sound of admiration or cheers all around.

In the 90s, 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 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 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 weren't security personnel with live ammunition watching, I'm afraid someone would have rushed up to hug and lick her on the spot.

As a decent person, Xi Boyang did not keep staring at the aircraft, 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 cycle is not less than 150 hours?"

"Holy shit... is this data serious? Why do I remember that I said before 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... very powerful?"

Someone next to me couldn't help but ask.

After all, not everyone knows so much about aviation power.

"It's more than 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 F80 turbofan engine newly developed by Americans in the 404s."

After his comparison, more people can understand.

"F404...is the one used on F18?"

"Yes."

"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 just making wild guesses and had no intention of hiding anything.

But even he himself felt that it was really 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 what's going on with the American F18. Just now I thought I heard someone say it's similar to this one."

……

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 performed the flight demonstration 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 amplified version of the MiG-21."

"No, Alyosha, there is no trace of the MiG-21 on that plane."

Bogosian 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.

Apparently 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 Alexei Bulatov. He is not actually a 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'm going to take a look at the Chinese exhibition area."

"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 aircraft, new engines, why have they suddenly become enlightened in the past year..."

Bogosian 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 improved Su-27 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 updates for flankerr’s reward.
