Gas Turbine Research Establishment

Gas Turbine Research Establishment (GTRE) is a laboratory of the Defence Research and Development Organisation (DRDO). Located in Bangalore, its primary function is research and development of aero gas-turbines for military aircraft. As a spin-off effect, GTRE has been developing marine gas-turbines also.
Products.
Principal achievements of Gas Turbine Research Establishment include:
GTX Kaveri.
GTX-35VS Kaveri Engine was intended to power production models of HAL Tejas.
Defending the program GTRE mentioned reasons for delay including:
Both hurdles having been cleared, GTRE intended to continue work on the AMCA (future generation fighter craft).
This program was abandoned in 2014.
Kaveri Marine Gas Turbine (KMGT).
Kaveri Marine Gas Turbine is a design spin-off from the Kaveri engine, designed for Indian combat aircraft. Using the core of the Kaveri engine, GTRE added low-pressure compressor and turbine as a gas generator and designed a free power turbine to generate shaft power for maritime applications.
The involvement of Indian Navy in the development and testing of the engine has given a tremendous boost to the programme
Ghatak.
The Ghatak engine will be a 52-kilonewton dry variant of the Kaveri aerospace engine and will be used in the UCAV (Unmanned Combat Aerial Vehicles). The Government of India has cleared a funding of INR 2650 Crores ($394 Million) for the project.
Manik Engine/Small Turbo Fan Engine (STFE).
GTRE is developing a new 4.25 kN thrust turbofan engine to power Nirbhay Cruise missile and future UAV, Long range AshM/LAM cruise missile systems. GTRE is working fast to add test capabilities and infrastructure to test the Manik engine.
Testing.
The KMGT was tested on the Marine Gas Turbine test bed, an Indian Navy facility at Vishakhapatnam.
The engine has been tested to its potential of 12 MW at ISA SL 35 °C condition, a requirement of the Navy to propel SNF class ships, such as the Rajput class destroyers.
