THIS PRESENTATION WILL GIVE A SIMPLE
DEMONSTRATION OF HOW JET ENGINE COMPRESSORS WORK
2
THE COMPRESSING ACTION CONSISTS OF TAKING A
QUANTITY OF AIR AND FORCING IT INTO A SMALLER AND
SMALLER SPACE
LETS SEE HOW THIS IS DONE

WHENEVER AIR IS FORCED INTO A SMALLER SPACE TWO
THINGS HAPPEN
FIRST- THE PRESSURE OF THE TRAPPED AIR INCREASES
SECOND- THE TEMPERATURE OF THE TRAPPED AIR ALSO
INCREASES
YOU CAN PROVE THESE TWO EFFECTS WITH A BICYCLE
PUMP!
IN A JET ENGINE COMPRESSOR, IT IS A CONSTANT FLOW
OF AIR CONSTANTLY BEING COMPRESSED.
