BRAYTON CYCLE: 

BRAYTON CYCLE

PowerPoint Presentation: 

The Brayton cycle is a thermodynamic cycle that describes the workings of the gas turbine engine, basis of the jet engine . It is also sometimes known as the Joule cycle. The Ericsson cycle is similar but uses external heat and incorporates the use of a regenerator. Reverse Brayton cycle: A Brayton cycle that is driven in reverse, via net work input, and when air is the working fluid, is the air refrigeration cycle Its purpose is to move heat, rather than produce work. This air cooling technique is Aircrafts

WORKING: 

WORKING COMPRESSOR: compresses the air and pressurize it COMBUSTION CHAMBER: where fuel air mixture are ignited and burnt TURBINE: burnt gases gets expanded AFTERBURNER: where reheating or extra fuel is sprayed to gases to get more thrust

METHODS TO IMPROVE: 

METHODS TO IMPROVE If pressure ratio is increased, efficiency also increased. If afterburner is used more thrust produced.
