Modified Kaveri engine to propel Indian Navy ships

-

The Gas Turbine Research Establishment (GTRE), Bangalore of Defence Research and Development Organisation (DRDO) which has been indigenously developing Kaveri engine for propelling the Indian Light Combat Aircraft (Tejas), has now come up with a modified marine version, as a spin off during research, 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 and 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 up to 25 MW of shaft power through a reduction gearbox and a water brake dynamometer.

The Indian Navy has been involved in the development of the engine and participated and supporting the testing phase.

The engine has been tested to its potential of 12 MW at ISA SL 35 degree C condition which is the requirement of Indian Navy for propelling the SNF (Rajput) class of ships.

This engine has been demonstrated to the Prime Minister Dr. Manmohan Singh and others including the Scientific Advisor to Defence Minister M. Natarajan, Vice Admiral B.S. Randhawa, Dr. D.Banerjee, Chief Controller of DRDO.

With this development, India will become self-reliant in the technology of gas turbines for ship propulsion.

This will put India in the elite club of Marine Gas Turbine designers for example USA, Russia, UK and Ukraine. By Kestur Vasuki

The first batch of the indigenously built T-90 Bhishma tanks was on Monday (August 24) flagged off by Minister of State for Defence MM Pallam Raju at the rolling out ceremony held at the Heavy Vehicles Factory, Avadi, in Chennai. The T-90S tank incorporates many new technologies in terms of mobility, protection, fighting capabilities, safety and communication. The tank is equipped with 125mm smooth bore gun stabilised in Elevation and Azimuth, 12.7mm anti-craft machine gun and 7.62mm co-axial machine gun supported with high accuracy sighting systems and Automatic Loader ensuring high rate of fire. A significant feature of this tank is its capability to fire guided missile in addition to conventional ammunition using the same main gun barrel. The integrated fire control system consisting of the gunner’s sight, guided weapon system and ballistic computer facilitates accurate firing of conventional ammunitions as well as the guided missiles. The built in Explosive Reactive Arm...
