Absolutely correct, I've got a professor here who holds a patent on prediction of Combustion instability(mainly acoustic instability) in gas turbine engine. You know, the reason why kaveri engine couldn't deliver the requiste thrust is ssomething to do with acoustic instability when the frequency of swirling flame inside combustion chamber matches with natural vibrating frequency of Combustion chamber- this induces cyclic stresses in longitudinal direction- i.e. tensile and compression. Any turbomachinery rotating at 50000RPM and undergoing cyclic stresses won't really last long.
How come they did not hire you to fix the problem with Kaveri? You seem like an expert on the topic. Also with all the research going on in India, the research papers being published and patents being issued it still have to import its ab-initio trainer and all its aviation programs have failed or just marginally successful after a lot of imported input.
