A gas turbine is a type of combustion engine that converts the energy from burning fuel into mechanical energy using a high-speed rotating shaft. It operates on the Brayton cycle, which involves compressing air, mixing it with fuel, igniting the mixture, and then expanding the high-pressure gases through a turbine to generate power.

How Does a Gas Turbine Work?

• Air Compression: Ambient air is compressed by a series of compressor blades, increasing its pressure.
• Combustion: The compressed air is mixed with fuel and ignited in a combustion chamber.
• Energy Expansion: The high-temperature, high-pressure gases expand through the turbine blades, causing the rotor to spin.
• Power Generation: The rotating shaft drives a generator to produce electricity.

Applications of Gas Turbines:

• Power Plants: Used in combined-cycle power plants for electricity generation.
• Aviation: Provide propulsion for aircraft engines.
• Marine Propulsion: Used in naval vessels and some commercial ships.

Advantages of Gas Turbines:

• Compact Size: Smaller and lighter compared to steam turbines, making them suitable for mobile applications.
• Quick Start-Up: Can reach full power quickly, making them ideal for peak shaving and emergency power.
