The Anatomy of an Aerospace Engine

The Anatomy of an Aerospace Engine


Airbreathing and non-airbreathing engines make up the two main categories of aerospace engines. For simplicity, Airbreathing engines (also known as airbreathers) function by utilizing the air that the aircraft is flying through, both as an oxidizer for the fuel in the combustion chamber and as a working fluid for thrust generation. Non-airbreathing engines are rocket engines in which the propellant gas is produced aboard the vehicle. A rocket engine is a type of jet propulsion system that generates thrust by ejecting stored substances known as a propellant.


Airbreathing engines are divided into 2 types: reciprocating engines and jet engines. The Wright brothers' first successful flight was propelled by a piston engine. Up until jet engines took over, it remained the predominant source of propulsion for aircraft. Piston engines with water-cooled engines were utilized from 1903 to 1908. Excess drag and weight created by liquid-cooled engines hampered airplane performance at the time. In 1908, liquid-cooled engines had been replaced by air-cooled ones, resulting in weight reductions of up 40%. However, the performance of these air-cooled engines fell short of expectations. To increase the efficiency of air-cooled aircraft, The National Advisory Committee for Aeronautics (NACA) created a cowling that encased the engine. This engine enclosure restricted the passage of air over the engine cylinders to air in contact with the cooling fins of the cylinders.


Aircraft engines come in all different shapes and sizes.


However, piston engines were much too heavy to compete with jet engines in terms of power output. The capacity to fly at greater altitudes and at faster speeds with simpler control is one of the most evident benefits of jet engines versus reciprocating engines. The increased airflow makes cooling less difficult. On the other hand, the continuous ignition system of the reciprocating engines is not required, spark plugs are only utilized for the startup. There is no need for a carburetor or a mixture control.


The first jet engines appeared in the 1940s, and during the next 60 years, they underwent enormous progress that has continued to this day. Whether they are turbojets, turbofans, or turboprops, the engines utilized in some aircraft applications are all collectively referred to as "jet engines."

The Most Turbulent Flights in the World Turbulence is a common phenomenon experienced on flights all across the world. However, factors such as weather that greatly influence turbulence are more prevalent in certain areas than others. This begs the question: are certain flights more prone to turbulence than others? The short answer is yes and many factors lead up to this. As such, today we will examine these factors and which air routes are the world's most turbulent. ROUTES READ MORE »

The Story of the Forgotten Emirates A340 Fleet The Airbus A340 is a long-range, wide-body passenger airliner that was developed and produced by Airbus. In the mid-1970s, Airbus developed the A340 quadjet. The A340-300 took its maiden flight on 25 October 1991. It was certified along with the A340-200 on 22 December 1992 and both versions entered service in March 1993 with launch customers Lufthansa and Air France. The larger A340-500/600 were launched on 8 December 1997; the A340-600 flew for the first time on 23 April 2001 and entered service on 1 August 2002. NEWS READ MORE »
