I am as pessimistic about Indian jet engines as it is humanly possible and for good reasons. Indian research is more of a starry-eyed fantasy which disregards our complete lack of a sophisticated production capabilities. What we need is a AK-47 of Jet Engine --if that is even possible--; something that Indian current production capabilities can mass produce rather than the most exotic jet engine ever conceived .
BTW, India private sector knows these realities. Which is why they produce Tata Nano kind of cars with engines designed for longevity and ease of production rather than greatest performance.
Russia is no US. They can not afford to lose India as a customer, especially when China is moving out of their order books very fast.
