The Kaveri Saga
Kaveri, an afterburning turbofan engine, was sanctioned on 30th March 1989 for ₹382.21 crore and was made to power the then-under development LCA. The venture was placed under GTRE, who already had quite an experience making engines. GTX37-14U was an augmented turbojet engine in 1977 and demonstrated in 1981, or a centrifugal type 10 kN thrust engine (i.e., F107-WR-105), which they made around 1959. Another low-bypass engine was made called GTX37-14UB with GTX 37-14U as its core, which was an 89 kN Class engine; it was proposed for LCA before Kaveri but was overruled due to its large frontal section. The GTX 37-14U was a flat-rated twin-spool turbojet having a throttle ratio of 1.13 and a bypass ratio of 0.2:1. Again, GTX 37-14U was also suffering from its own fair share of problems. Let's talk about Kaveri or GTX-35VS: It's an afterburning, twin-spool, low-bypass turbofan engine. It borrows its core, called Kabini, from it....
