My point is clearly lost on you.

BTW, I was only half joking with my remark about showing off to Robert Gates though. You don’t gather much useful test data in less than 20 minutes and the aircraft did not seem to be instrumented particularly extensively – no strain gauges all over the place, unlike the T-50. The apparent lack of follow-up flights so far lends further credence to the theory that this maiden sortie was mainly a publicity stunt, not the start of the actual test campaign (yet).

There is always another one for static test, why fit strain guages all over the flying one? I haven’t seen that on flying T-50 either, can you plz show me one?

also… How dare they fly publicly if not enough ‘actual’ test and tuning has already been done? J-20 has a very active configuration, the tuning of control law would be extremely complicated. Again what were those low/high speed taxi and engine test for before it’s first flight then?:rolleyes:
Even my RC planes need hell lots of tests and tuning before it’s first flight:p

and more extensive flight test has always been Yanliang’s job, not in Chengdu.
maybe that’s why no more flights had been spoted.

good, bet for what this time, eat a hat again or a keyboard?:dev2:

I should halt my RC J-20 project and start making chocolate hats and keyboards…:D Might make very good money

The one area where China still lags behind is avionics. Remember Pakistanis wanting to fit French missiles and European radars onto their JF 17s ?

Yet India use completely indigenous radar and missiles:D

I think a lot of people with manufacturing background would kind of agree (that computer software has destroyed talent) if this was directed at the CATIA wielding comunity.

don’t know much about CATIA but I can’t live without Solid Edge and NX now:D

Can I ask for a favor from some of our Chinese users regarding detailed translation of this pic?
More or less I know which systems and components are represented but still I would be thankful for an accurate translation…

left column:
Inlet, fuel tanks, Main weapon bay, side weapon bay, APU/AMAD/TMS, OBIGGS,
right column:
case and accessories, Lubrication system , Drag chute bay, hydraulic systems

I think the contrast of this pic was somehow altered from the original drawing…

however….

🙂

hmmm very close…:D

new pic spoted, it is based on a real photo but landing gears PSed out.

No, we built more reference system.
You can estimate height of standard human body’s caudal vertebra
I presumed that man who stood aside the main wheel is about 1.75 meters tall
You can see that diameter of J-20’s main wheel almost reach a man’s loin.
So the result was guided to only way which could taught us to assume the diameter of J-20’s main wheel same as Su-27’s is an excessively conservative measurement.
Further more, you guys should know since the volum of J-20 is distinctly bigger than Su-27/35, if its diameter of main wheel is not enlarged, the intensity pressure the tire got would be too high.
I’d rather insist the 15 meter for wing span, or say more approaching to 15 meters

Did you notice the man is closer to the camera?:rolleyes:
