Jet engines work through the process of compression, combustion, and expansion, generating thrust to propel the aircraft forward.
Bypass air, which exits the engine without going through the core, plays a crucial role in generating thrust and making the engine more efficient.
Jet engines consist of various components including the fan blade, compressor section, combustion chamber, turbines, and exhaust, all working together to produce thrust and power the aircraft.
