Mr Fomin has most of the Vzlet magazines available for free download (except the last 3 numbers )

I think this is the magazine in question…

I think it’s a wikipedia mistake anyway. Current engines from what i’ve read around are Izdeliye 117, which are upgraded Izdeliye 117S( from Su-35) , and capable of 15,000( 15,300?) kgf.

Aparently this “Izdeliye 127” ( 17,500-18,000kgf?) engine is intended to be ready to power the “second stage” T-50 ( lets hypothetically call it T-50M)

NPO Saturn : “…engines on current T-50 prototypes much different from Izdeliye 117S on Su-35S”…or something like that.:)

From Sukhoi:

Interfax is wrong, the T-50-2 flew for 44 minutes ( as per Sukhoi).

is there a source/link where the current status of the flight testing is summarized (how many flights, flying hours, reached test objectives and so on) ??

Don’t think so , that aint the russian way.:p

Now that T-50-2 is up , and knowing that initially it was slated to fly in november 2010, and also i think it was stated (or rumoured? i’m not sure) that T-50-3 was intially slated for the first quarter of this year , does that mean that now the third prototype will also be offset at least 4-5 months ? Any rumours of when it is suposed to fly according to the revised schedule? (i know that offcourse it’s suposed to fly sometime this year)

Also regarding 51…according to take-off.ru , it re-entered flight tests on 10th of february ( if i got the translation right). Does anyone know how many times it flew from LII so far?

Holy cow , thanks Jo Asakura! Now the interesting bit is , does it have the IRST or EO ball under the tail boom aswell …:rolleyes:

Regarding the differences , it seems that looking closely the IRST appears to be in the center of the windscreen , and the all-moving fins appear completely metalic now ( no dielectric top like on 51).:confused:

If you look carefully this one seems to have a real IRST over the nose (as oposed to the mock-up on 51 and KNS), also the strain gauges on the tails look different.

Eagerly waiting for high-rez ones!
