Water turbine took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" for "whirling" or a "vortex". The main difference between early water turbines and water wheels is a swirl component of the water which passes energy to a spinning rotor. This additional component of motion allowed the turbine to be smaller than a water wheel of
Gas Turbine Research Establishment 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. The involvement of Indian Navy in the development and testing of the engine has given a tremendous boost to the programme The Ghatak engine 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
