A gas turbine is a type of internal combustion engine that uses pressurized air to rotate a turbine wheel at high speeds It is a highly efficient and reliable type of engine that provides high power output while consuming relatively small amounts of fuel. Gas turbines are widely used in both stationary and mobile applications, such as power plants, ships, aircraft, and automobiles.
The basic design of a gas turbine consists of a compressor, a combustion chamber, and a turbine. The compressor compresses air which is then heated by burning fuel in the combustion chamber. The hot air is then directed to the turbine, which rotates as it expands, producing a rotation force on the turbine wheel. This rotation force is transferred to a shaft or gearbox, which provides the output shaft power.
Gas turbines offer several advantages over other types of power generation equipment, such as higher power-to-weight ratios, lower pollutant emissions, and more compact designs. They can also be more efficient than reciprocating engines due to their higher compression ratios and increased air flow through the turbine.
Here are five of the best examples of gas turbines:
1. Pratt & Whitney FT8: The Pratt & Whitney FT8 is a high-efficiency low-emission turbofan engine designed for commercial aircraft. It features advanced technologies such as full authority digital engine control, which allows for precise fuel control and improved engine performance.
