Gas Turbine A turbine driven by the expansion of burning fuel.  A gas turbine that has been cut away to show the internals. Back Work Ratio The fraction of the gas turbine work used to drive the compressor. Blade Clearance Gap between blade and casing. Simple Cycle Referring to the gas turbine cycle consisting only of compression, combustion and expansion. Historical Notes - 1791 John Barber patents the basic gas turbine in 1791.
- 1870 George Brayton proposes the thermodynamic cycle for the Gas Turbine. Now known as the Brayton Cycle.
- 1930 Sir Frank Whittle patented the design for a gas turbine for jet propulsion.
- 1949 first gas turbine for an electric utility was installed in Oklahoma as part of a combined-cycle power plant. It was built by General Electric and produced 3.5 MW of power.
