Webb5 sep. 2012 · A gas turbine engine is a device that is designed to convert the thermal energy of a fuel into some form of useful power, such as mechanical (or shaft) power or a highspeed thrust of a jet. The engine consists, basically, of a gas generator and a power-conversion section, as shown in Figures 1.1 and 1.2. WebbA gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. [1] The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: a rotating gas compressor. a combustor. a compressor-driving turbine. ray bernoties
