Gas Turbine Research Establishment Explained

Gas Turbine Research Establishment
Established:1959
City:Bengaluru
Research Field:Aerogas turbine technology
Director:Shri. Dr. S V Ramana Murthy
Operating Agency:Defence Research and Development Organisation
Country:India
State:Karnataka
Former Name:Gas Turbine Research Centre (GTRC)

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.[1]

Products

Principal achievements of Gas Turbine Research Establishment include:

GTX Kaveri

See main article: GTRE GTX-35VS Kaveri. GTX-35VS Kaveri engine was intended to power production models of HAL Tejas.[3]

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.[4]

The involvement of Indian Navy in the development and testing of the engine has given a tremendous boost to the programme. The base frame for KMGT was developed by private player Larsen & Toubro (L&T).[5]

Ghatak engine

The engine for DRDO Ghatak 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 2,650 crores ($394 Million) for the project.[6]

Manik Engine

Small Turbofan Engine (STFE), also known as Manik engine is a 4.5 kN thrust turbofan engine developed by GTRE to power Nirbhay series cruise missile and under development UAVs, Long range Anti-ship and Land Attack cruise missile systems.[7] In October 2022, STFE was successfully flight tested.[8]

DRDO is currently on search for a private production partner to mass produce Manik engine. It is estimated that 300 units will be produced over the course of five years. This amount could be allocated to the GTRE-identified industries. An Expression of Interest (EOI) will first identify two industries to supply three engines each over the course of eighteen months. After that, an RFI for mass production quantities will be issued.[9]

In July 2024, ABI Showatech India Pvt Ltd was awarded the contract to supply Casting Vane Low-Pressure Turbine (LPNGV) subcomponent of the engine as a part of the cruise missile programme. The low pressure turbine is "responsible for extracting energy from the exhaust gases to drive the fan and other compressor stages."[10]

Testing

The KMGT was tested on the Marine Gas Turbine test bed, an Indian Navy facility at Vishakhapatnam.[11]

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.[12]
