Gas turbine on and off to run it only at high efficiency. The emergence of the continuously variable transmission may also alleviate the responsiveness problem. Turbines have historically been more expensive to produce than piston engines, though this is partly because piston engines have been mass-produced in huge quantities for decades, while small gas turbine engines are rarities; however, turbines are mass-produced in the closely related form of the turbocharger. The turbocharger is basically a compact and simple free shaft radial gas turbine which is driven by the piston engine's exhaust gas. The centripetal turbine wheel drives a centrifugal compressor wheel through
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
