Jet engines operate based on the principle of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In the case of jet engines, air is drawn into the engine, compressed, mixed with fuel, ignited, and then expelled at high speed through a nozzle, generating thrust. This process is known as the Brayton cycle, which is the thermodynamic cycle that describes the functioning of the jet engine.
Propulsion systems, on the other hand, encompass a broader range of technologies that produce thrust for aerospace vehicles. This can include not only jet engines but also rocket engines, propellers, and other forms of propulsion.
