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.


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[edit]

GTX-35VS Kaveri Engine is intended to power production models of HAL Tejas.[1]

GTRE will be successful soon to come up with successful engine ( in terms of required thrust) for the HF-2000 Tejas fighter aircraft.

In its defence the GTRE has mentioned that the reasons for delay as : Non availability of state of the art wind tunnel facility in India The technology restrictions imposed by US by placing it in "entities" list

Now both these hurdles have been cleared and GTRE is planning to work on the AMCA (future generation fighter craft).

This program as of 2014 has been abandoned.

Kaveri Marine Gas Turbine (KMGT)[edit]

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.[2]

The involvement of Indian Navy in the development and testing of the engine has given a tremendous boost to the programme.


The KMGT was tested on the Marine Gas Turbine test bed, an Indian Navy facility at Vishakhapatnam.[3]

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.[4]
