What is an Aircraft Engine? How Does it Work?
So, what is an aircraft engine?
The first generation of aircraft had a propeller mechanism powered by engines resembling car engines. However, this situation changed over time. In terms of air transport, one of the biggest developments was the start of the use of turbojet engines in 1952. Propeller engines and jet engines had their own advantages and disadvantages. It has been observed many times that attempts were made to combine the good aspects of both engines into a single engine.
How does it work?
The most commonly used aircraft engine during this period is known as the turbofan engine. These aircraft engines force a large fan, connected to turbines, and a very high volume of air through a duct surrounding the jet engine. This airflow passes through the fan ducts, gains higher speed, and exits, significantly increasing the total thrust of the aircraft engine. The turbofan aircraft engine is designed based on the principle that a larger amount of air moving at a much lower speed creates much greater thrust than a smaller amount of air moving at a much faster speed. The first commercially produced turbofan aircraft engine was tested and successful in 1955. A turbofan or jet engine on an aircraft can be easily distinguished from a less efficient turbojet aircraft engine by the bulky appearance of the nacelle covering the fan. The thrust produced by a turbojet engine is approximately twice the speed of sound when considering the speed of the aircraft, due to exhaust gases. The high-speed exhaust gases from a turbofan aircraft engine meet the lower-speed air passing through the fan, thereby significantly reducing engine noise. New cooling techniques are located at the exit of the engine's combustion chamber. Gas temperatures in these parts can rise above 1500 degrees. Thus, the aircraft's efficiency increases significantly. Aircraft technology is developing day by day. The combination of the two engines has greatly benefited the speed of aircraft. Further development is expected over time.
