Turbojet Engines: What Makes Them Tick?

Posted on October 16, 2019 Henry Fayol Aerospace News

Turbojet engines are truly fascinating pieces of machinery. An array of tiny, individual pieces combine to form something greater than the sum of its parts. While it would be irresponsible to imply that they are simple machines, when you break down a turbojet engine, they are surprisingly easy to understand. Turbojet engines consist of just five primary components. These are the intake, compressor, combustion chamber, turbine, and exhaust.

Air enters through the intake and is funnelled back towards the compressor. Once there, the air is heated and compressed. From here, the air passes into the combustion chamber where, once mixed with fuel, it ignites. This burning fuel creates energy through the heat and expansion of the air. The energy required to power the compressor is removed from the exhaust stream by the turbine. The turbine has sharp discs that rapidly spin as hot gases leave the combustor. The rest of the energy from the exhaust is used to create thrust, which in turn is enhanced by the exhaust nozzle. As the exhaust gas exits via the nozzle, it is accelerated as it expands, therefore providing the propelling force necessary to move the plan forward. 

The basic way an aircraft jet engine works is through the hyper-acceleration of small amounts of air to high speeds. Optimum efficiency of these engines cannot be reached until the speed of the accelerated air roughly matches that of the aircraft. Therefore, turbojet engines do not reach their peak operating ability until speeds around mach 2, over 1500 mph.

While the main components of turbojet engines are relatively simple, each component is made of many individual parts.
