A turbine engine is a type of internal combustion engine that converts fuel into mechanical energy. It works by drawing in air, compressing it, mixing it with fuel, and igniting the mixture. The resulting high-pressure exhaust gases then expand through a turbine, which spins and produces thrust or drives a generator. Turbine engines are commonly used in aircraft, where they are known as jet engines. They are also found in power plants, where they generate electricity. The efficiency and power of turbine engines make them essential for modern transportation and energy production.
