Advanced Medium Combat Aircraft [AMCA] Development | Updates & Discussions.

Black bird was used such hybrid engine,

One of several designs that would fit the "Partial Ramjet" category. The X-7 helped pioneer the design that would eventually grace the Blackbird:

The Blackbird used what could be called a Turboramjet, the J58, which provided higher trust when operating at higher speeds versus lower ones:

You can't lay the performance of the engine solely on its design, though. The nacelle it sat in provided benefits too - specifically the shock spike:

And you're right that this type of engine design is less maneuverable as it was designed to operate at sustained high speeds where fuel economy was also greater as a consequence. A drop in speed lessened the engine's efficiency.

If course it didn't help that the SR-71 was 107 feet long. Which that size and being optimized for high speed missions, both by your design and engine and mission, you'd be hard-pressed not to have a turn radius the size of Texas.

Instead of a Turboramjet design, which is optimized for sustained high-speeds, a type of ADVENT engine would be best for a future fighter aircraft:

ADVENT or Adaptive Versatile Engine Technology engines are designed to be what their name suggests, adaptable, and can adjust their performance at lower or higher speeds, as well as their fuel economy. This type of engine lessens the necessity of dedicated high-speed optimized engines like the J58 and engines that perform better at slow-to-medium speeds.
 
Bro it's internal weapon carrying capacity is 2ton. Wing external hard point if fully loaded it can easily carry approx 8ton including internal+ external
Tnq u....,but external weapon configuration will kill the very purposes of amca ie enter enemy airspace being undetected.
 
Its better to throw this project down the dustbin if we are not vying for an Indian Power plant here.

Else I see this as Debacle LCA PART 2.

Even with the purposed GE engine it's not going to be a true fifth gen aircraft anyway. And that's one of the items by the way.
R & D is what required to achieve that capability.

Before even thinking about AMCA it should be the subsystems which should be our focus.
An Indian AESA radar in service which can be improved in future to be used IN AMCA , Indian ECM systems , Indian Power plant , thought we can take Russian help to get thrust vectoring , Indian Infrared and RF based AAMs, light weight cruise missiles , next generation small diameter laser and GPS guided munitions ,aircraft cannon ,Indian refueling probe , Indian next generation Onboard Oxygen generating system ,Indian secure radio and satellite links ,Indian IRST , Indian Targeting pod ,Indian HMDS,Indian HOTAS, etc.

When we have all these, we will be able to design an Indian 5th gen aircraft which in true sense will have multi role capability and will be sanction proof.

Then AMCA will never be a reality,we can't make whole fifth gen aircraft alone.

That will be a better option then. Simply buy off the shelf , and buy the assembling rights and then carry on as we have been doing.
 
Y dont they put a GE 414 EPE in the mk 2...? It would make it future proof
chances are high for GE141 EPE version in first batch of AMCA if india goes for advance super hornet instead of F16V or grippen E as the second MRCA under MII
