Products

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

GTX-35VS Kaveri Engine was intended to power production models of HAL Tejas.Gunston, Bill (Ed.) (15 June 2006). "GTRE Kaveri" in ''Jane’s Aero-Engines'', Issue 14. Coulsdon, Surrey, UK: Jane's Information Group Limited. . 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.
