fanne-ji, Karan M-ji, this type of money only makes sense for a 4+ Gen TF with a TVC maybe - aka something that b
oasts min TWR of >9, ~1550+ deg C TeT and >27-28 OPR, and maybe even fluidic TVC etc.
Ofcourse these parameters are not the real benchmarks of a true-blue 4.5Gen TF etc, but here, looking at some of responses above, maybe such kind of characterization is required.
A behemoth that huffs-puffs via a 9-stage HPC (and a 3 stage LPC) to achieve 23OPR etc - and also its 0.5 etc BPR would mean, the dry-thrust ratings it actually achieves (should be classified) in Indian conditions, will be waaay below that what the shiny brochures would be claiming.
Summary is, this is just not in the league of TFs, that can demand that kind of a price.
In fact it's successor, AL-41F is not either ... these
prices are realistic for Izdeliya-30 kind of a TF, where-in the technologies involved are actually 5+ Gen.
So, until and unless, we have been given a free hand wrt replacing the
entire core (including the hot-section) with materials and manufacturing tech of our choice, without invalidating the warranty etc, this type of pricing makes no sense at all.
Don't want to make it a long post, so let me just say/claim this - given a free-hand, there are
ample scope of "upgrading" it to AL-31F-MKI (you heard the nomenclature here, first) std,
purely via already developed desi technology (from Kaveri and HTFE programs) and materials.
And only the threat of invalidating the product warranty by the OEM, constrains us from going ahead with such a program.
