How do Jet Engines Work?

Jets engines work by harnessing the principles of jet propulsion to produce thrust. This allows an aircraft to move forward and overcome the forces of drag. The process begins with the intake of air, which passes through the engine's components, undergoes compression, fuel combustion, and exhausts out the back, creating a high-velocity jet of gases that propels the aircraft forward.
