I think we dont need any out of the box solution...wheel has already been invented... we just need to learn (experiment) and perfect an every aspect of a jet engine.....I think we need to develop more expertise in the area of metallurgy...I dont know if our institutions are well equipped to train people in that domain! But we seriously need to do more as we are billion plus people and we should not rely on foreign countries for such an important tech in long run!
This is an interesting read if you want to understand the technology,
Jewel in the crown: Rolls-Royce's single-crystal turbine blade casting foundry | In-depth | The Engineer
The single-crystal structure isn’t intended to cope with temperature, however; it’s to make the blades resistant to the huge mechanical loads that result from their rotational speed. “Every single blade extracts power from the gas stream equivalent to a Formula One car engine,” Glover said. “And the centrifugal force on them is equivalent to the weight of a double-decker bus.
When it crystallises, nickel forms a structure known as face-centred cubic (fcc); each cube has a face with five atoms, one at each corner and one in the middle. When alloys are made, generally the atoms just swap in and out of the fcc lattice. But under the right conditions, aluminium and nickel combine in such a way that nickel goes to the centre of the faces and aluminium to the corners.
“In the bulk alloy, you’d place the balls representing the components of the alloy, about 10 different elements including nickel, aluminium, chromium, tantalum and titanium, pretty randomly, and when you got to the gamma-prime precipitate you’d put in this ordered arrangement of aluminium at the corners and nickel in the middle. It’s all on the same regular lattice, oriented the same way, so it’s all the same crystal, but you have these much stronger regions where there’s the array of gamma-prime precipitate.”
Business Minister opens the most Advanced Turbine Blade Casting Facility in the world – Rolls-Royce
Rolls-Royce today marked the official opening of its new £110m Advanced Blade Casting Facility (ABCF) with a ceremony conducted by Business Minister Matthew Hancock. When fully operational in 2017, the 150,000 sq ft (14,000 sq m) facility in Rotherham will employ 150 people and have the capacity to manufacture more than
100,000 single crystal turbine blades a year
u need standing ovation 
@GURU DUTT @Zebra would u take care or should i destroy this thread
