The World's 4th, 4.5 & 5th Generation Fighters

Re: Russian fifth generation fighter

I think if you read the iranian news media, it is a UAV not an aircraft and they just tested a prototype model not something that is flying around. They still claim they need to do work on it.

Who knows, they might be able to build a LO UCAV.

Re: Russian fifth generation fighter

challenger the Japanese has been looking into developing there own Fifth gen but there seems too be a debate as too whether there is a need for the Mitsubishi ATD-X Shinshin ( one's mind) or if either the new F15SE or EF2000 would fit the bill and south korea is still early in consept

They definitely can and I have no doubt they will field a stealth fighter because they already have the makings of one in the Shafaq. The real issue is getting all the other elements of a fifth-generation fighter like supercruise and AESA.

Re: Russian fifth generation fighter

In regard to the PAK-FA's stealth intakes, maybe the PAK-FA uses long, triangular protrusions to hide the engine's face (like a isosceles triangle with a very wide base and a curved tip). Put one protrusion on the right/inner side and front half of the air intake, and put one ramp on the left/outer side and rear half of the air intake. Each protrusion's width is one-half the net total width of the air intakes. The result is an S-shape tunnel in the air intakes.

Maybe just use one long, triangular protrusion on the inner side and front half of the air intake, because the PAK-FA's engines seem to be less wide than the air intakes, the engines are located slightly higher than the air intakes, and the engines' center seem to be closer to the centerline than the air intakes center. The result is a V-shape tunnel in the air intakes.

Re: Russian fifth generation fighter

Actually, I think the PAK-FA does have s-shaped intakes. Instead of the S being perpendicular or parallel to the planform of the plane it's diagonal.

Re: Russian fifth generation fighter

The S-intakes could be diagonal. It could increase the stealth. However, I don't think the S-intakes are diagonal based on the few pictures I have seen of the PAK-FA. They are probably slightly diagonal due to the different location of the center of intake and the center of the engine's face, but I think the S-intakes are mostly on the x-axis or the y-axis.

Take a look at this picture of the PAK-FA: .

If the stealth for the air intake uses protrusions on the bottom and top of the air intakes, then the bottom protrusion can store weapons or shoot out missiles from the bottom of the air intake. If the protrusions are on the side walls of the air intakes, then the side protrusions can store the landing gear and store weapons or shoot out missiles from the bottom of the air intake. If the protrusions are diagonal, then you could have better stealth, but inferior storage space for weapons or inferior ability to shoot out weapons from the bottom of the air intake.

Like I previously said, another possibility is the use of one protrusion so the air intake looks like a V-shape: the air enters horizontally and towards the backside, then the air is gradually directed upwards and towards the backside.

Let's see if these'll upload:





四代机：
中国的四代重歼就是歼14，编号没错！但网上说它的综合性能匹敌F22，这是夸大的！歼14已经设计定型并试飞。其综合性能不及F22已经是肯定的了！歼14的真实目标其实F35！歼14不会大量装备部队也已经基本确定！它是用来外销的就像目前的枭龙！
《简氏》有篇文章是说歼14将飞遍亚洲的天空（可以查的到的）就是说歼14主要外销的事的！（我并非在促销《简氏》但它的很多关于中国武器的报道惊人的准确。这一点已经引起了中国军方高度重视）
F35不是将大量装备美国的盟友吗？那么歼14就是中国的对策！而且歼14做为准四代重歼，极具市场竞争力！
虽然歼14单机不如F22，但大家也不必担忧。在中国的地面上，地空配合是可以打下F22的。
中国真正的最强悍战机并非歼14，是另一款已经设计定型的飞机歼X（编号涉密）。该机的所有参数我想大家都很难猜到。
歼14、歼X都已经设计定型并且试飞！中国在三代向四代的跨越有点像原子弹向氢弹的跨越，速度超快！
不要怀疑这一点！比如歼10，曝光前四年就已经装备部队了！而它的曝光所透漏的信息就是：歼10并非我国最强战机（要不然我们也不会曝光），它的下一代已经完成设计并生产了！

For those of you who savvy Hanzi, I'll let you be the judge. I won't add any to any of this otherwise I'll be hammered as crapping.

mods note >>> as you know this is an English language forum. So how about a good translation? I tried the google translation and it was not very good.

Re: Russian fifth generation fighter

That's an interesting perspective. But I don't recall hearing anything about this J-X, perhaps an unmanned craft? And what is this followup to the J-10 that this rumor talks about?

Sorry, Mate, I'll have to admit, the job of translating is way way out of my league. I'm a mere dummy who doesn't know a thing about Egyptian Hierography and I'm not about to be brave about it. However, I'm sure plenty a forumite here are more than comfy with it, Kobato and tphuang could be such fine examples. I was hoping for them to drop by and show us a little of their leadership quality.

I suspect a test bed for something revolutionary. Chengdu fiddles with a lot of ideas annually. This is as far as I'll go with this. I'm not adding anything else to this because, I can still recall how everyone crapped us Chinese over in the Keyboard in the 90's when we were adamant about the then rumors of the J-10.
