J-20 5th Gen Fighter Thread IV (Closed to posting)

[airsuperiority]

A detail. pixels are not accurate at all, why? simply if you zoom them you see colored squared that does not give you a real measurement of where the jet begins and where it ends.
So here is where the subjectivity plays the biggest role, you will chose the dimensions of each jet according to your liking

Su-35 measures Length, m 21.9
Height, m 5.9
Wing span, m 14.7

See Su-35 it has no pitot tube, therefore a size range, of a 20-21 meters range is more accurate, why? because the Su-33 looks almost the same size so hardly J-20 will be 1.5 meters shorter than Su-27 and.77 meters shorter than Su-33, specially where you can not see where it does begin or end.

im surprised even with this you can still find something to nitpick. no wonder einstein once said imagination is greater than knowledge

all of us are imaging things, when you give me AVIC`s page with official dimensions i will say you did not imagine, Sukhoi does not yet give dimensions for PAKFA yet only Lockheed Martin does for F-22, the rest is especulation and in that you are included as well as me, for that i say range size range better than a fixed number i always have said J-20 is between 20.5-21.5 meters, never an exact number

The aircraft has been designed to deliver a highly stealthy configuration at low cost, with a heavy weapons load capability over a wide combat radius, says Avic. The model is a single-seat, twin-tail, twin-engine aircraft with a high wing, like the real aircraft seen in unattributed photographs on the Internet. As described at the show, the fighter has a typical takeoff weight of 17.5 metric tons, is 16.9 meters (55.5 ft.) long and 4.8 meters high with a wingspan of 11.5 meters.


Avic says the J-31 has a combat radius of 1,250 km (780 mi.) on internal fuel or 2,000 km with external tanks. Maximum speed is Mach 1.8, takeoff distance is 400 meters and its landing distance 600 meters

this give a clear idea those 20 meters and 17 tonnes are just a range and not exact dimensions

by the way the speed shows their DSI are as conventional as F-35, well at least J-31, but i guess J-20 won`t be different

I think that almost all new fighter types have their top speeds around 1,8 Mach because You just don't need more speed. Unless You want to go extremely high Mach numbers but that would be totally another story.

17, even 18 tons for j20 seems a bit low for a plane full of RA materials. Perhaps chengdu opted not to combat C and S wavelengths with RA materials?

Nah, they are in the prototype stage of flight testing and tweaking, NO POINT in coatings at this stage of developement. They have a baseline radar sigs and know where they are at with that, VLO and RAM testing will come when the flying and tweaking is more or less nailed down. With only two prototypes and no real production info it is way to early to get ansy about the RAM, with panels coming off and on after every flight, there is just no point? AFB

Up to what i have read, yes T-50 has the potential of being navalized but that is not now a fact since Russia only has an aircraft carrier, now the Su-33 is the only naval fighter until MiG-29s will do the job after 2015.
So you can say PAKFA still is an air force project

The naval T-50 is like the Light fifth generation fighter, it might be developed but is not a fact yet, it will depend in if Russia develops their projected aircraft carriers or the needs arises

Thanks for your answer. Keep us updated if you find anything new.

Well Jr. that depends on who you want to believe, the F-22 will supercruise at that speed and the J-20, J-31, and the T-50 will almost certainly be in the same ballpark as the F-22 on top end, I would hazard a guess of Mach 2.2+. How the others will stack up at supercruise will ultimately depend on the powerplants, weight, and how slick they are, I would imagine that the Russians will push the top end on the T-50 up as far as is possible, The J-31 will most certainly get better powerplants if it survives the cut, and the J-20, T-50, F-22 will likely all end up at 2.2 or a little better. Now the F-35 is what it is, and Mach 1.8 is pretty fast for a Strike Aircraft, so where does that leave us?----the old Fighter Pilot addage was that speed is life, I'll stick to that until someone shows that it is no longer relevant, and L/O technology is constantly changing so we shall see? Welcome to Sino Defense? AFB

I see that you don't understand how basic turbofan engine technology works.

Please explain what you mean for the rest of us?
