Water turbine like a true turbine. Fausto Veranzio in his book "Machinae Novae" (1595) described a vertical axis mill with a rotor similar to that of a Francis turbine. Johann Segner developed a reactive water turbine (Segner wheel) in the mid-18th century in Kingdom of Hungary. It had a horizontal axis and was a precursor to modern water turbines. It is a very simple machine that is still produced today for use in small hydro sites. Segner worked with Euler on some of the early mathematical theories of turbine design. In the 18th century, a Dr. Robert Barker invented a similar reaction
Gas Turbine Research Establishment Gas Turbine Research Establishment Gas Turbine Research Establishment (GTRE) is a laboratory of the Defence Research and Development Organisation (DRDO). Located in Bangalore, 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. Principal achievements of Gas Turbine Research Establishment include: GTX-35VS Kaveri Engine was intended to power production models of HAL Tejas. 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
