Gas turbines are a type of internal combustion engine that converts natural gas or other fuels into mechanical energy. They are widely used in power plants to generate electricity, providing a reliable and efficient source of energy. The basic operation involves compressing air, mixing it with fuel, and igniting the mixture to produce high-speed exhaust gases that drive a turbine. These engines are also utilized in aviation, where they power jet aircraft. Their design allows for high power-to-weight ratios, making them ideal for flight. Overall, gas turbines play a crucial role in modern energy systems and transportation.
