Right there it says Japan, what's indigenous? I call bs....no need to call indigenous when your progress is much dependant on foreign countries. Opposite of indigenous.... What a load of crap

Do you not know how to read cause It literally written right there on the document that it's an indigenous in house development.

UNICORN for Future Indian Ships - Alpha Defense

India and Japan Collaborate on UNICORN Naval Technology for Indian Navy's Indigenous Integrated Mast (IIM)

I think after comparing the schematics of both the systems it can be said without a shadow of doubt that UNICORN and IIM are infact 2 different Masts and IIM is not a license production of UNICORN.

From what I could gather and understand, Japan will help us in the development of IIM by guiding and hand holding us in the development process, In short it would be more like mentorship than license production

What sensor, elaborate?? It's simply not a final deliverable config as of yet.

Those wires will be dangling for the first couple of user trials also. They keep data for all under-trial equipment to gauge the performance. Sensors include but are not limited to, Temperature sensors, stress/strain sensors, etc. @Chinmoy might know better.

That thrust increase of 2200 lbf ...... are they talking about AL-41? Because that is the difference in dry thrust between AL-31 and AL-41

Man if the news is true and if its going to be made with indigenously developed materials - its great news. 👍 it would mean our material science research for turbines is going in right direction. It shall have positive effect overall in R&D space.

Yeah, but what about the afterburner. Plus I don't know if the Russians would agree to this without demanding hafta, they own the engine IP after-all. Could this be a deal with the Russians after all?

Could be .. but with sanctions I believe this might be the way out.If India developed using its own materials kb - its for sure Russia shall object but given there is no direct dollar trade and Russia may not be keen on having more Indian Rupees in its Vostro account holding on. They may be holding their silence now until project fructifies

No, thats just 10kN increment, making it closer to the one AL31 variant China used for its J-10.
Its modestly far from AL41 thrust. AL-41 is significantly different than AL-31, it makes sense to buy higher thrust AL-31 variant which we have experience with.

AL-31 variant on Su-30 has 76.5 kN
AL-41 variant on Su-35 has 86.3 kN
10 kN difference.

What is the confusion? Are you getting confused with wet thrust? That is what I said:-

Why are you assuming that the thrust increase is only for dry ? Wouldn't they mention both if it was separate. If we are getting Al-41. Dry and wet both will increase, right.

So here is the confusion,
1. What kind of technological breakthrough made the thrust increase? Is it Single Crystal Blades or Blisk or Fan Inlet Diameter increase or Turbine Inlet Temperature increase?
2. Is the technology for the upgraded engine indigenously developed demonstrating increased capability in our metallurgy or its just russkies imparting some developed from their own AL-41?
3. What does it mean when entire engine is built from Raw Materials? Does it mean Afterburner section also?
4. The final most burning question is keeping aside whether russkies like it or not, whether they approve it or not, if Modi orders HAL to print a AL-31 engine, can they be able to do it? Or are there still subcomponents in Engine need to be imported from Russia directly which we are not able to indigenize?

Indeed. But reason I am only assuming it is about dry thrust is because the upgrades listed will increase dry thrust. Nothing about the AB is mentioned. Which is why I am also confused if they are talking about a domestic upgrade or did someone finally blink in the AL-41 negotiations.

What does it even mean, if bel is doing it then why Japan was involved. This is why our projects are smoke and mirrors and endless B's without inductions in numbers or time. Interim mean same shit testing now and then, is interim not good enough? Then why all this halla bulla on every product branded as indigenous when it's domestically made. I know how to read and digest. I am calling out on the nonsense of calling indigenous a domestic solution.
I can speculate the seeds of this confusion anywhere from license production to cheap political points. If interim is domestic then don't call iim indigenous as it's implicit unless they are covering it.
