Sir.
The sanction for Kaveri happened in 1990. They made initial tests but could not succeed. The actual backing was given by Vajpayee in 1998-99 along with Tejas LCA.
I am surprised that you find it necessary to keep posting fiction and figment of imagination. For example, your statement here exemplifies that you are an obstinate person who neither knows, nor is willing to know.
Fact check for you:
Project LCA was conceived in 1981 (
B.N. Raghunandan, Charlie Oommen, R.K. Sullerey in Air Breathing Engines & Aerospace Propulsion: Proceedings of NCABE 2004) and GTRE expressed it's confidence in provision of an engine for the project in 1981 itself. At the time, GTRE was already ready with configured experimental engines GTX-37-14U and GTX-37-14UB. Based on this, they promised delivery of the engine for LCA, which, once the ASQR was issued in 1985, was found to be untenable. GTRE concluded that 'there was no engine in the world which could match the specification required in the ASQR' and the work had to be started on the Kaveri from scratch. The development started in first quarter of 1989 and your claim as above is - hogwash.
Please do note that around this time India was being actively wooed by USA in the backdrop of USSR's Afghanistan intervention. In early 1980s, US offered GE 404 for India's LCA project and the same was taken up (please note that this engine was ready by 1978 and was to power the F-18s entering US forces in 80s).
It would please you to note that the GTRE was tasked with finding an engine for the aircraft and had failed to mention about the suitability of GE-404 (something which they had imported by 1987 or thereabouts).
It shall also please you to note that the HAL had already prepared the designs for a follow on of Marut by 1975, which could not take to skies due to non-availability of a suitable engine.
At the time, US was not willing to offer an engine to India. The situation was to change with Soviet intervention into Afghanistan. Also it shall please you to note that the Indian scientists were already well enroute to assimilating critical know how in Carbon Composites, for this program.
Your subsequent post is a plethora of refuse that has no value either.
Kabini C1 and C2 underwent ground test from 1995 to 1998 (350 hours) and 45 hours of Altitude tests.
Satisfied by the performance of C1 and C2, and with inputs from the tests, GTRE was confident of Kaveri. (K1, K2 and K3) Tests from same, both ground and altitude, allowed the GTRE the confidence to fabricate the graded weight engine K4. (K4, K5, K8 and K9 developed earlier than K6 and K7). K5 underwent further 56 hours of Exploratory Altitude Testing for different altitudes and mach numbers. Based on successful tests of K5, further refinement in weight was undertaken. Time was taken by MIDHANI and DMRL to match up to specifications required for the alloys needed. The delay was more due to ecosystem being created.
All this was occurring as years went by and the ASQR underwent changes with passage of time.
It is also interesting to note that by 1993, according to CAG report of 2015, 54 permanent waivers of critical types were obtained by ADA-HAL-GTRE over the original ASQR. IAF was willing to dilution of ASQR as long as the product came on time (1990s).
How much fund do you want? 1 lakh crores?Do quantify the same. As for test bed, ADA-HAL-GTRE undertook the responsibility to create an ecosystem. May I enquire as to how two engines as mentioned earlier by me, were ready by 1981?
