    Yes, any engine can be derated to a lower thrust rating. You can even flat rate an engine to a lower thrust level.

    Answering your question, DRDO has not directly taken any offsets so far. Presently, Rafale has an offset clause, and DRDO has been asked to fill it up. we are specifically talking of the Kaveri engine’s last mile problem. we are running the five Kaveri engines that we have. These were even flown as a part of the experimental test-bed in Russia. we know they are good engines. The problem with the engine is that when used for higher power, it makes a noise. we don’t know the effect it can have on the performance. to resolve this issue, DRDO is planning to rope in snecma (as part of the Rafale offset). The project has already entered the first phase. snecma will study the engine and work on its modifications, certify and fit it on the Light combat Aircraft (LcA) tejas. we should be able to fly one of the LcA’s with Kaveri engine at least after two years.

    According to wiki Avanger C drone uses a Pratt & Whitney Canada PW545B engine with 17.75 kn thrust.

    Engine dimension are
    Length 68.6 inches = 1740 mm approx
    Diameter 27.3 inches = 6930 mm approx

    and we have HTFE-25 with same length and smaller diameter with 40% more thrust. I believe our own Avenger C type program is already in work.
    Also BAE Transis and Dassult nEUROn both uses Rolls-Royce/Turboméca Adour with 29 kn thrust which is much bigger and heavy engine. So a scalled up model of this engine will even sufficent for AURA/Ghatak.

    During one aero india seminar someone from HAL aero engine division called HTFE-25 a TD. So don't keep high hopes here.
