@gslv mk3 : No use of posting all this, its still a massive failure for those who cannot phantom what it takes to build an entire industry from base. People who only know paint job will never under what goes in engineering and manufacturing.

Impressive to say the least.
And all this starting from scratch!

Inverted fir tree root design, this is similar to what KWU/BHEL designed High pressure turbines have for steam turbines.
I have two questions here:
1. Do jet engines too have concept of rotary and station blades as we have in steam turbines?
2. What are those oval holes (running axially) along the outer curvature of blade? Haven't seen these in Steam turbines.

1.Yes,jet engine compressors have rotating blades and stationary vanes
2. Those oval holes is put to create a cover of cool air (600+ degree Celsius :p) over the blades.


P.S: I am no expert and will be happy to be corrected

despite great promise and expectations this project has been delayed beyond any reasonable explanations

Delays are there, no doubt. But in no way its a failed project as some members like to picture. Its more like a student scoring a 85 out of 100 when he is capable of scoring a 100 out of 100. And every one has their mistakes in it,ADA,HAL,IAF,GoI
