'''Gas Turbine Research Establishment (GTRE)''' is a laboratory of the [[Defence Research and Development Organisation]] (DRDO). Located in Bengaluru, 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.

It was initially known as GTRC (Gas Turbine Research Centre), created in 1959 in No.4 BRD Air Force Station, [[Kanpur]], [[Uttar Pradesh]]. In November 1961 it was brought under DRDO, renamed to '''GTRE''' and moved to [[Bengaluru]], [[Karnataka]].<ref>{{Cite web |title=About Us {{!}} Defence Research and Development Organisation - DRDO, Ministry of Defence, Government of India |url=https://www.drdo.gov.in/labs-establishment/about-us/gas-turbine-research-establishment-gtre |access-date=2022-10-29 |website=www.drdo.gov.in}}</ref>

Principal achievements of Gas Turbine Research Establishment include:
* Design and development of India's "first centrifugal type 10 kN 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===

[[GTRE GTX-35VS Kaveri|GTX-35VS Kaveri]] Engine was intended to power production models of [[HAL Tejas]].<ref name="JAE2006">Gunston, Bill (Ed.) (15 June 2006). "GTRE Kaveri" in ''Jane’s Aero-Engines'', Issue 14. Coulsdon, Surrey, UK: Jane's Information Group Limited. {{ISBN|0-7106-1405-5}}.</ref>

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 [[HAL AMCA|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.<ref name="GTRE develops engine for navy">{{cite web |url=http://www.newindpress.com/NewsItems.asp?ID=IEH20080717034427 |title=DRDO develops marine gas turbine engine for Indian Navy |publisher=Newindpress.com |access-date=2012-01-28 }}{{dead link|date=October 2017 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

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 vehicle|Unmanned Combat Aerial Vehicles]]). The [[Government of India]] has cleared a funding of [[Indian rupee|₹]]2,650 [[Crore|crores]] ($394 Million) for the project.<ref>{{Cite web|url=http://www.americanbazaaronline.com/2015/12/14/project-ghatak-india-to-make-indigenous-stealth-combat-drones/|title=Project Ghatak: India to make indigenous stealth combat drones|last=Bazaar|first=The American|date=2015-12-14|website=The American Bazaar|access-date=2016-07-08}}</ref>

=== 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.<ref name=":1">{{Cite news|url=https://www.theweek.in/news/india/2019/04/16/nirbhay-cruise-missile-to-be-tested-desi-engine-future.html|title=Nirbhay cruise missile to be tested with 'desi' engine in future|date=16 April 2019|work=The Week|access-date=26 August 2019}}</ref>

==Testing==
The KMGT was tested on the Marine Gas Turbine test bed, an [[Indian Navy]] facility at [[Vishakhapatnam]].<ref>{{cite web |url=http://frontierindia.net/demonstration-of-12-mw-kaveri-marine-gas-turbine-for-indian-navy |title=Demonstration of 12 MW Kaveri Marine Gas Turbine for Indian Navy | Frontier India - News, Analysis, Opinion |publisher=Frontier India |date=2008-07-17 |access-date=2012-01-28 |url-status=dead |archive-url=https://web.archive.org/web/20120318203428/http://frontierindia.net/demonstration-of-12-mw-kaveri-marine-gas-turbine-for-indian-navy |archive-date=2012-03-18 }}</ref>

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]].<ref>{{cite web|url=http://pib.nic.in/newsite/erelease.aspx?relid=40470 |title=Modified Kaveri Engine to Propel Indian Navy Ships |publisher=Press Information Bureau, Government of India |date=17 July 2008 | first=Sitanshu | last=Kar |access-date=12 January 2019}}</ref>
