gázturbinahajtóm

A gázturbinahajtóm, commonly known as a gas turbine engine, is a type of internal combustion engine that uses the Brayton cycle to generate power. It operates by compressing incoming air, mixing it with fuel, and igniting the mixture. The resulting hot, high-pressure gases then expand through a turbine, which drives a compressor and often an output shaft. This process allows for the generation of mechanical power or thrust.

The primary components of a gas turbine engine include a compressor, a combustor, and a turbine. The compressor increases the pressure of the intake air. The combustor is where fuel is injected and burned, creating hot, expanding gases. The turbine extracts energy from these gases to drive the compressor and produce output power. Gas turbines are widely used in aviation as jet engines, providing propulsion for aircraft. They are also employed in power generation for electricity production, particularly in peaking power plants due to their rapid startup capabilities. Additionally, gas turbines are utilized in industrial applications, such as driving pumps and compressors in oil and gas facilities.

The efficiency of a gas turbine can be improved through various methods, including increasing the turbine inlet temperature, improving component aerodynamics, and employing combined cycles where the waste heat from the gas turbine is used to generate additional electricity in a steam turbine. Despite their advantages in power-to-weight ratio and flexibility, gas turbines are susceptible to high operating temperatures and can be less fuel-efficient than other engine types in certain applications.
