A turbojet engine primarily generates thrust by accelerating high-speed exhaust gases. In simple terms, the operation of a turbojet involves drawing in air through an intake, compressing it in the compressor, mixing it with fuel, and igniting the mixture in the combustion chamber. The high-pressure, high-temperature gases produced from combustion then expand rapidly through the turbine and exit the engine at a high speed through the nozzle. This rapid expulsion of exhaust gases creates a reaction force in the opposite direction, according to Newton's third law of motion, thereby producing thrust.

This principle is fundamental to the design and operational efficiency of turbojet engines. The acceleration of the exhaust gases is what enables turbojets to achieve high speeds and altitude performance, effectively propelling the aircraft.
