here we go, 18year old riveting machines at KnAAPO working on Sukhoi Superjet 100 airframes asembly….:D:D:D:D

April 2012
4 Brotje riveting machines at the work

I remember having seen a mock up of a faceted Su-47 on a desk of a russian aerospace designer/representative?.

seems to be messing up. there was a model of S-32 or some interim design at the table of Pogosyan – different intakes and seemingly different exhausts. I’ve seen at least three different intake designs offered for S-32/S-37 family

The other good question is , Is the Berkut still being tested?

no. last flights were ca. autumn of 2009. it’s mothballed now at the northern ridge of Sukhoi hangar at LII

And another nice question is, Was the Berkut used as T-50 testbed?, or the T-50s technologies were tested in the Berkut program?

I believe the Su-47 was never used as a PAKFA testbed, is ridiculous, because both designs, parameters, and objectives are completely different, I believe the Berkut program added some PAKFA technologies (as the bomb bay doors), for the Berkut program, not for the T-50 one.

all depends on what do you think term ‘testbed’ is (which you take plain wrong)
737 CATB is a testbed for F-35 bit none says that designs are the same
and no, it’s T-50 weapon bay that was tested on Su-47

a regional jet where only factory riveters and plumbers to build fuselage and wings are needed as everything else is manufactured outside Russia

o’rly? then Boeing seems to be in trouble, too

oh, and Embraer, too!

btw, percentage of import goods in SCJ yearly reports varies from 40 to 60%. Slightly too much stays for rivets, don’t you think so? And there are already machine riveting and plumbing at KnAAPO if you don’t know.

it seems the wing structure, spar to spar was from composite materials only.

you have X-ray vision? in fact, it was not, and spars are titanium

btw, that’s how weapon bays doors represented at model…:diablo:

original S-37 had two (or four – all depends of your way of counting) weapon bays – two smaller behind the nose landing gear door for two short-range AAMs and two for four medium-range AAMs. Not sure for forward bays, but large ones had two bi-fold doors each.

back in 2006 a/c main weapon bay was modified to represent T-50 weapon bay with its much wider nomenclature of weapons – hence it was deeper and S-37 got it’s pregnant look as making it flush to a/c bottom would cause major structural redesign of middle fuselage. more, aerodynamic dept wanted to move bay down as it allowed to get clearer picture of its behavior

initially modified T-50 representative bay had metal bay doors that could be opened/closed only at the ground (that allowed brave fence checkers to get rare pics of weapon bay open), and first – narrow – version of airstream spoiler. in 2006-2007 a/c performed more than 70 flights in such a configuration

in 2008 bay was modified with composite doors that could be operated in flight, missile launchers and new improved spoiler and aerodynamic deflector at the rear wall
in 2008-2009 aircraft performed 25 flights, including flights with Article 180 MRAAM mockups

you can believe whatever source you want) or check how fast Rafale flies with such inlets
of course, inlet ducts are not fully represented on model – mainly as time-saving measure than secrecy
but I don’t need to look inside real inlet to see how duct swirls – I just can look at some drawings

I wonder who ever told you that S-37 would fly M=2.35?
btw, it’s my very own photo)
while model has almost all of the panel lines so sought by rivet counter modelers around the world, it lacks panel lines at the weapon bay area due to classification issues, and inlet tracts end with rounded deadlock a dozen inches behind inlet lips
