J-20 5th Gen Fighter Thread VI

The support frame is on the inside of the canopy only, that means the outside retains the same blemish free finish of the original. Together with RCS treatment and shaping, it means the frame adds nothing to the RCS of the plane, because the canopy is specially designed to not allow radio waves to enter and exit freely. Otherwise you have much bigger problems than the frame messing up your frontal RCS.

As for why it was added, there was a report years back about the canopy starting to warp and loose structural integrity during high speed flight from the heat. The frame was added to lend the canopy additional support.

The ejection method was also changed at the same from from whole canopy ejection to through canopy ejection with the addition of detcords.

I recently heard a Raptor pilot on a podcast who revealed that the F-22's cockpit is too small for the JHMC, it literally bangs against the walls if the pilot wears it. That may explain the problem with having a completely frameless design, which only the Raptor does. It limits the size of the cockpit maybe, you have to make it sleeker to avoid friction heat. The Viper still has a frame behind the pilot. The problem with the Viper cockpit is that at high mach it gets so hot that the pilot has to slow down, (also heard this from a Viper pilot on a podcast)... I would think that could be easily fixed by better air conditioning lolz.

Anyone remember the F22 canopy cut out ?

cost how much ?

Can't believe that it has been nine years already. Time flies.

Indeed ... and therefore it's time for something new:

I suggest finally some clear images of the painted FC-31V2, or even right a confirmation for the alleged J-35 ... or a J-20A in grey with WS-10C and new serial numbers, ... OR....

Has it already been nine years? Hello, old friend. All images are high-resolution.

Yes, gone is the lovely canopy and the fabulous speed brake, both of which added unneeded complexity and expense, it seems that the gear doors and their operation has been tweaked a bit as well, as tips clipped here and there and inlets resized and reshaped. Lots of updates after these proof of concept aircraft...

and I would add that 2001 and 2002/2004 were flown out to Yangling as were the early pre-production birds..... I would like to imagine they are still and important part of the test fleet there?? and as BY 78 suggests hopefully they will be preserved for the enjoyment of those who have so much emotionally invested in this beautiful airplane.

Disclosure by J20 pilot during CCTV interview : Positive overload 9G, negative overload -2 to -3G, side overload 4G.

What is "side overload"?

If I am not mistaken this is the same interview I translated back around the October 1st parade. I don’t think they mentioned side overload during that interview.

I'm rather positive that you are correct, and no, there was no mention of a yaw G limit, in fact although we all know aircraft can be broken in many different directions, in aircraft spec sheets we see a positive g limit and a negative g limit.

This anecdotal account calls the negative G limit- 2-3, no very precise at all, and I'll tell you why,,,, when I pressed my bud "KLEPTO" the F-22 jockey, on how many negative G's he had ever pulled he stated it exactly in that way.... "oh, two or three, hell I don't know, they are absolutely miserable, nobody does that for fun..

Now he's very precise in calling the positive G limit at 9 G's, because he has very likely pulled 9 G's,,,, so lets clear this up once and for all, the J-20 is a positive 9 G, Negative 3 G air frame, if you understand anything about structures and how each additional G multiplies the force on the air frame exponentially, you would no doubt agree with me that the J-20 is a least a 19 ton air frame.
