Afterburn:

The term afterburn refers to a process commonly used in jet engines to enhance their thrust output.

Definition:

Afterburn, also known as “reheat,” is an additional combustion process that occurs in the exhaust section of a jet engine.

Process:

After the main combustion is completed in the engine’s combustion chamber, unburned fuel is injected into the exhaust and ignited.

Enhanced Thrust:

This ignition of extra fuel in the exhaust section generates a significant increase in the jet engine’s temperature and exhaust velocity, leading to enhanced thrust.

Applications:

Afterburn is primarily employed in military aircraft and supersonic jets where additional thrust is crucial for high-speed operations.

Advantages:

The implementation of afterburn allows for improved acceleration, higher maximum speeds, and enhanced maneuverability in certain aircraft.

Disadvantages:

Although afterburn increases thrust, it leads to higher fuel consumption and decreases the overall fuel efficiency of the engine.
