Austin- No. There are 2 primary considerations that rule out the 117. Firstly the need for the highest attainable dry military thrust for sustained supercruise in conjunction with the aerodynamic efficiency of the T-50. This is important tactically and for combat persistence especially given Russia’s huge land mass.
The second pertains to the AC power generation derived from the turbine speed and synchronous power generator. The PAK-FA has a whole host of avionics systems that are World firsts and will be extremely power hungry.
These reasons are probably high on the list when the former head of NPO Saturn, Ilya Fyodorov, described 117 production as “not economically viable”.
Btw, the direct Russian counterpart to the F119-PW-100 is Salyut’s AL-31F-M3. It has the same number of stages (3+6+1+1), and delivers slightly less power @ 15.3T (33,700lbs).
Here we have a combustor developed by MMPP Salyut and a firm specialising in mathematical flow models (may or may not be related to Izd.30):
Their objective is to get the wall temperature of the combustion chamber >150°C lower than that of the legacy AL-31Fs – this will have a significant impact on the burn efficiency of the fuel-air mixture.
As one can appreciate, such components are part of greater ‘clean sheet’ design to derive the maximum benefit to achieve an end goal.
Mmmmmm…..truly mouthwatering, thanks.
I wonder if the ОЧК has anything to do with the rumoured adaptive wing. Here’s the SSJ’s ОЧК:
…anyways, roll on the CNT/fullerene RAM, PMC cowlings, eye popping tolerances and rivet covers.
