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:
 Design and development of India's "first centrifugal type 10kN thrust engine" between 1959-61.
 Design and development of a "1700K reheat system" for the Orpheus 703 engine to boost its power. The redesigned system was certified in 1973.
 Successful upgrade of the reheat system of the Orpheus 703 to 2000K.
 Improvement of the Orpheus 703 engine by replacing "the front subsonic compressor stage" with a "transonic compressor stage" to increase the "basic dry thrust" of the engine.
 Design and development of a "demonstrator" gas turbine engine—GTX 37-14U—for fighter aircraft. Performance trials commenced in 1977 and the "demonstrator phase" was completed in 1981. The GTX 37-14U was "configured" and "optimized" to build a "low by-pass ratio jet engine" for "multirole performance aircraft". This engine was dubbed GTX 37-14U B.

GTX Kaveri

GTX-35VS Kaveri Engine was intended to power production models of HAL Tejas.

Defending the program GTRE mentioned reasons for delay including:
 Non availability of state of the art wind tunnel facility in India
 The technology restrictions imposed by US by placing it in "entities" list

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.

K-Series Engine 
 DRDO K-9 kaveri (90 97 kN) turbofan engines project
 K-10
 K-10 (107 128 kN) turbofan engines project

Manik Engine 
 DRDO Manik 4.25 kN small turbofan powering Nirbhay missile

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.
