The current blades already have ceramic coatings to enable about 300 kelvin/celsius increase in TET. The SCB blades are unlikely and it is likely to be 2nd generation DS blades. SC blades have 3 generations. First generation has no rhenium while second and third have 3% and 6% rhenium. The TET...

I am not sure of that. But, the idea of light fighter was in older times where there was clear separation between interceptor, strike etc. In those time, FBW was not available and laser guided bombs were also unavailable and hence there was a need for specialisation. Such specialisation makes no...

All planes nowadays are multirole. Let us not joke ourselves by saying Su30 is not able to bomb but only air dominance. Tejas can also bomb and do air dominance.

Kaveri engine has 63\98kN thrust. But current F404 has 54\84kN thrust. The increase in thrust is about 17% which means that the MToW must also raise hy same amount to about 16-16.5 tons from current 13.5 tons MToW even with some aerodynamic improvement I don't see Tejas becoming medium weight...

Where are the hard points located in Gripen E that add up to 10?

You have to compare Gripen E with Tejas Mk2. Gripen E has empty weight of 8tons and f414 engine but MToW of 16.5 tons. This 17.5 MToW is the suspect. How does Tejas have 1 ton more MToW when engine ia similar to F414? How will the eztra payload be adjusted? The 2 hardpoints at wing tips are...

The newer Kaveri is expected to be in 105kN class and it may be used in AMCA too. So, LCA MK2 has been increased in size to use the maximum potential of the engine. About 700kg increase, the current fuel is 2460kg and that will likely be 3.2tonnes. It is 4000 litre fuel. Also, about 1m increase...

Then it is ToT or at best ToT-exchange, not partnership. I don't think Rolls Royce offered that to India. Rolls Royce offered only partnership which may mean that some things will be Indian while some from Rolls-Royce. Since India wants technology if Rolls Royce and not just combined designing...

What do you mean by partnership? Is it about paying Rolls Royce heavily so that they can get the engine developed and then allow India to assemble it? How will engine quest come to an end if full IPR is not given and India will not be able to manufacture it inhouse? I think it has been stated...

Sorry, I confused EJ200 with EJ230. Anyways, EJ230 is not complete yet. I am not even sure if it will be pursued further as the EU has no plane that needs it. Designing engines at billions of dollars price without having a use for it may not be what Rolls Royce wants.

Who told you that the weight of EJ230 with TVC is 1050kg? Also, EJ230 is 90kN, not 108kN thrust. They are hoping to make it 108kN but that is unlikely as the TWR is already high at 9 for EJ230. Making it higher may be difficult

It is difficult to make an engine heavier without making it bigger. Increasing thickness of parts will reduce area for air flow. Also, the heat will increase due to compression. A metal of 1kg and 10kg melts at the same temperature. So, even thick blades will melt if temperature rises beyond a point

I don't know about LEVCONS, but IAF strongly demanded additional fuel. IAF wanted 4000litre fuel capacity (3200kg, roughly). IAF argued that to fly longer missions with more payload, higher fuel is mandatory. With 30% extra internal fuel and higher payload, the ability to carry external fuel...

Where is the canards which was said to have been present to make it supermaneuverable?

How will the thrust increase without any change? Will they make the engine bigger and heavier? If the engine becomes heavier, then it is meaningless

Here I will quote that: The hot section saw CMC in static parts only, not rotating ones: Just do control+F and find the paragraph. Also, quote the lines which say that 20% increase was seen. I could not see any. I you are saying that EPE is expected to have 20% higher thrust, the you are...

The key word here is LPTB or "Low-pressure turbine blades". What is needed is HPTB or "High-pressure turbine blades"

Yes, GE tested it with cold section, not hot. I have mentioned it in my comment. The hot section is the key. Cold section blades are insignificant and only serve to reduce weight

The EPE is supposed to use CMC blades instead of metal blades. It will provide higher temperature tolerance than rhenium based superalloy including 3rd generation SCB. But that is a distant dream.

The idea of the EPE engine was to get a CMC blade and disk for hot section. They managed to get CMC for cold section but that provides little advantage except for slight weight reduction. The temperature of cold region is significantly low that all blades work well without having to worry about...
