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 system technician Gas turbine system technician Gas turbine systems technicians (abbreviated as GS) is a United States Navy occupational rating. Gas turbine systems technicians (electrical) (GSE) operate, repair, and perform organizational and intermediate maintenance on electrical components of gas turbine engines, main propulsion machinery, auxiliary equipment, propulsion control systems, assigned electrical and electronic circuitry up to the printed circuit and alarm and warning circuitry. Gas turbine systems technicians (mechanical) (GSM) operate, repair, and perform organizational and intermediate maintenance on mechanical components of gas turbine engines, main propulsion machinery (including gears, shafts, and controllable pitch propellers), assigned auxiliary equipment and propulsion control systems.
