perhaps not in the area of engine and structurally
but what about in avionics and software expertise ? given that almost everything is computer controlled surely the indian engineers have in fact a lot to offer ? eg they could take the avoinics up a generation or two, working TOGETHER with russian engineers ?
Not in avionics as well...
Look, military equipment at all and 5 gen aionics in particular is not the same as commercial/consumer one.
It uses different architecture, materials, development and productiuon approaches and even some different physical principals (look at tera-GHz SUHF signal processing units for example).
Indian engineering doesn't know anything of that and should learn it as well as engine and airframe technologies.
Indian software devs are ...
Well, we will not describe a quality of mass-producted Indian commercial developers, but in military purposes software development skills is not the main part. Software engineer should be a great mathematician to build appropriate fucking complex ALGORYTHMS, not programs, which are secondary, and the same physician to deeply understand the subject he models in the algorythms. A lot of learning will be here as well.
India has good composits, but they are not appropriate for such a high loaded and high speed airframe, as pure Carbon/Carbon parts and units cannot withstand maneuver loads on supersonic speeds when leading edges heat by drag to 150-300 deg Celcious and have a long lifetime after that.
Russians have spent a 1.5 decades to invent and technologize mixed Carbon/Aramide technology. Aramides themselves give the parts structural and temperature flexibility that pure carbon cannot reach. But usual aramides (like Kevlar) have short lifetime (about 10 years with direct sunlight influation), dissolate on direct sunlight and have different thermal expansion coefficien which makes them impossible to be in one part with Carbon ones (they simply will tear the part a pieces when putted into autoclave for polymerization).
But Russians have invented Para and Meta Aramides that have 40 years and almost no sunlight impact.
Their TEC is almost the same as for Carbon fiber, so there is a mixed strings composite tissue is now possible.
Also they have developed A LOT ceapper way to autoclave them using composite matrices instead of fucking expensive Invar made US ones.
So, there are LOTS of technologies should be TOTted.
