Turbine waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to Swedish engineer Gustaf de Laval (1845–1913) for invention of the impulse turbine. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery. The word "turbine" was coined in 1822 by the French mining engineer Claude Burdin from the
Turbine-electric transmission generator is operated when the gas turbine engine is running and also when the motor's battery needs charging. The aircraft gas turbine engine system, patent number 5,867,979, is a gas turbine engine that is mounted on an aircraft, which the system generates and utilizes electrical and other power. The gas engine turbine system’s core is made up of a compressor, a three shaft propulsive gas turbine engine, which has three electrical generators. Each generator is connected to one segment of the shaft, which is part of the engine. Then a propulsive fan is driven by the compressor and the generators.
