HOW JET ENGINES WORK
Low-pressure turbine TURBOFAN Outer drive shaft
Fan sucks
Heat shield air in Exhaust gases
provide extra thrust
Blade tip
sealing shroud
Fan Bypass air provides
blade main thrust
Exhaust
cone High-pressure turbine
Rotating blades Fuel spins outer drive shaft
compress air inlet to drive compressor
Inner drive shaft
Fuel/air mixture ignites
TURBOPROP
Combustion
chamber
Fuel inlet Three-stage turbine
Compressor driven by hot gas
sucks air in
Core jet pipe Propeller spins
(exhaust to provide Exhaust gases
fairing) main thrust add a little thrust
Rotating blades Turbine shaft drives
Reduction gearbox
compress air propeller and
Scavenge oil line compressor

TURBOJET Combustion
Inter-module chamber
bolted joint Fuel inlet Turbine blades
Compressor driven by hot gas
Fuel shut-off valve cable sucks air in
SECTIONED PRATT & WHITNEY Exhaust gases
CANADA PW305 MODERN TURBOFAN provide all
the thrust
Rotating blades Fuel/air Turbine drives
compress air mixture compressor via drive
