DRDO takes 30 years for reaching to prototype stage for LCA TEJA
are you sure DRDO is able to complete this project in your life

troll....know how to read .......its already being done...its not project any more

Is this the same technology that is used to create Single Crystal Blade and DRDO was having trouble creating for kaveri engine.

Havent we heard this before as well.. ? Will be interesting to see what effect this "discovery" has on the non-moving Kaveri.

yes its the same......

single crystal casting process for high pressure turbine blades (HPTB) and high pressure turbine vanes (HPTV)

yes its the same......

So what does this mean in regard to Kaveri development as SCB was one of the main focus point in its development.

SCB able to withstand more mechanical stress and higher operating temperature ......unlike directionally solidification which is used presently....

But DRDO presented Directionally solidified blades quite sometime ago and said that they were working towards very high heat resistive blades

Directionally solidified blades (DSB) is from 70s technology where SCB is 90s technology....
SCB have higher turbine inlet temperature than DSB.......
SCB>>>>1150 C
DSB>>>>1000 C

Directionally solidified blades used quite sometime ago and looks like parallely they were working on the SCB casting and successful in making SCB

Developed??? More like they got TOT...
