Gas Turbine Research Establishment, Bangalore of DRDO had been indigenously developing Kaveri engine for propelling the Indian Light Combat Aircraft (Tejas). As a spin off during development, a marine version has been evolved to develop shaft power for propelling Indian Naval ship. Using the core of the Kaveri engine, the scientists of GTRE have added Low Pressure Compressor & Turbine as a gas generator and designed a Free Power Turbine to generate shaft Power for the maritime application.
The Kaveri Marine Gas Turbine (KMGT) as it has been named has been transported to Naval Dock Yard, Vishakapatnam and installed on to the Marine Gas Turbine test bed which is an Indian Navy Facility capable of testing the Gas Turbines upto 25 MW of shaft power through a reduction gearbox and a water brake dynamometer.
The involvement of Indian Navy in the development of the engine including their participation during testing has given a tremendous push to the success achieved so far.
During the recent visit of the Prime Minister of India, Dr. Manmohan Singh to Naval Dock Yard, Vishakapatnam, T Mohana Rao, Director, GTRE has demonstrated the engine to the VVIP along with the Senior Naval Officers. The engine has been further tested to its potential of 12 MW at ISA SL 35°C condition which is the requirement of Indian Navy for propelling the SNF (Rajput) class of ships. This peak power was demonstrated to various dignitaries including the Scientific Advisor to Raksha Mantri Shri M. Natarajan, Vice Admiral B S Randhawa, PVSM, AVSM, VSM, Dr. D.Banerjee, CC (R&D) among others.
