Demonstration of 12 MW Kaveri Marine Gas Turbine for Indian Navy

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.




  1. mera bharat mahan says:

    here lies the difference between the IAF and the IN:

    1) the navy worked with GTRE to get the product they wanted

    2) the navy invested in test facilities and came up with testing procedures to test and refine the product to their satisfaction

    3) the navy set realistic goals that can be achieved given the current competence level of the country (this is our first marine gas turbine, we’ll only get better). unlike the IAF, the navy did not set their requirements based on glossy magazines: they could have very well said that the GE LM6000 produces 44MW and this is the expectation they have from GTRE.

    let’s not even discuss the pathetic and short-sighted IA

  2. If the KMGT developed by GTRE is only 12MV max whereas their goal is to develop an engine with a max power of about 19MV, then there is nothing much to crow about.

    It is akin to the power plant developed for the LCA. Even with the claimed performance of 95% for the aero engine, the GTRE has failed to reach the intended target of 100%.
    Using this as a yardstick, how long would it take the GTRE to achieve the 19MV for its marine engine? GTRE is really pathetic when it comes to research and delivery schedule.

    GTRE should learn to walk the talk. What is really depressing is to hear grandiose schemes and declarations to please the visiting VIP babus but when it comes to the actual delivery per schedule, there is nothing much to boast about.

  3. It’s incremental. Let them first pass the Brakish water test first. Let us usee the if the metaulargy passes the saline water tests. To early to celebrate.

    By the way, 95% Kaveri Engine thurst is wrong. It has reached 100% thrust. As per FI article it will exceed the thrust. The problem comes when it engages reheat. That is where it has 95% thrust. Certain modules have to be changes. Specifically the exhaust area where heat is maximum. The GTRE metal casing is not able to sustain it. The second area is the fan blades whic have a lower life.

    What GTRE will try to do is integrate the 9.5 Engine to one of the PV’s and fly it. Once it has necessary flying hours, they will derate it and fit into planes with lower thrust needs like IJT.

    Everything depends upon the confidence. They need to install it and fly it.
