There is more to Jet engine design than SCB. Much more. GTRE needs things other than SCB too. We will have our own SCB already available and being industrialised as we speak. I have posted some details in past. Its not even a show stopper. In fact we can always get them "Make to Print" from either French or Americans or British for Kaveri, store large number of spares to remove uncertainties in supply during war times, and be done with it.
And yes, we could use their extensive toilet cleaning techniques in India too. LOL.
and what if no one will make to your print because their govt says don't do it??
or is it because nothing in kaveri has reached any stage of finality yet?? and no one has the faintest idea when such a happy occasion may actually come about??
I thought that SCB was the final hurdle and that crossed, it would be all khushal mangal for the Indian aviation scene, and you are saying that there is more, much more??
Kaveri doesn't even use SCBs saar. SCB is not *needed* for Kaveri's success in terms of achieving the original design objectives. Right now there are two or three issues which are already listed in recent posts.
But for it to power LCA and remain relevant, it needs to become 90kN class engine, For that it needs:
- higher TET (SCB helps in only this one parameter and nowhere else. And that too one can jack up TET by may be 50deg over and above DS blades, not more. Better cooling technology also needed for that.)
- Better materials across the components to support higher temp operations with decent life
- improvement in Aerodynamic and thermal efficiencies of Compressors and turbines (need 3D aerodynamics)
- reduced weight (better, lighter materials, Blisk tech, better structural design methodology)
- improvement in Combustion efficiency (better CFD tools)
- full set of ground and flight testing facilities
- lots of money and experience
- A whole lot of manufacturing technologies which we do not have
