Isnt 16.5T engine thrust on the lower side ? Just 1.5 T higher than present engine ?

That’s the upper-end of the RuAF requirement (for the stage 2 engine).
So it’s official for the 2-D nozzle. :diablo:

Description (via GTrans)

(54 ) flat nozzle turbojet engine

( 57 ) Abstract:
The invention relates to aircraft engine , namely the construction of nozzles turbojet engines . Flat nozzle comprises a body , the upper and lower rotary wing , fixed side walls, ram , extra ram and rotary frame . One end of the power cylinder is attached to the hull, and the other connected to the upper sash by turning the rotary frame . Swing frame is made with a triangular cross section. The surface of the rotating frame , facing the flow of the nozzle is cylindrical. Additional power cylinder with one end attached to the side wall , and others connected with the lower downstream end of the upper sash. The axis of rotation of the frame rigidly attached to the sides of the nozzle. The invention makes it possible to change the thrust vector engine, and also reduce the aerodynamic losses due to flow around the outer and inner surface of the nozzle and increase the engine thrust .

Nice one obligatory, it’s a pity that pfcem seems to have disappeared – it would have been fun to watch him spin that one 😉

Go easy on pfcem, he once said that he “expects the T-50’s RCS to at least equal the F-35” (!)…..whereas others still screech “it just aint so!!”.

Nobody seems to want to comment on the press report that the Su-35’s frontal RCS has been reduced to less than 1m^2 :eek:, a considerable achievement, imho.

these 5 radars all over the T-50 will be a signals management nightmare wont they?

Thales, Northrop Grumman, Raytheon and no doubt others are developing multipurpose conformal arrays with a shared common aperture, that enables array distribution in the wings & fuselage.

Tikhomirov-NIIP are taking a different approach by integrating both an X & L band system- with L-band acting as a cueing system for the X-band.

I don’t think the T-50 will have 5 radars, more like 3 (the main X-band, and 2-L-band arrays in the wings), combined with a capable passive RHAWS system.

The true multi-purpose conformal array(s) will probably follow later (imho).

See Thales’ ‘cloud transmit/receive module’ for the Rafale MLU:

R-27R1/ R-27ER1 have mid-course inertial guidance;
R-27T1/ R-27ET1 has what’s called an “updated proportional guidance algorithm”:

That Su-33 pic looks awesome.

Y.I.P needs to haul his kit ‘n skills up to Zhukovsky to do ‘Blue 51‘ some real justice! :cool:……that guy bottom-right’s a bit close, huh?

Is not the Zaslon antenna bigger than the Bars one?

D’oh!! my bad, Zaslon-M is a recent development:
