Instruments in an aircraft have two purposes: to display current flight conditions (such as airspeed and altitude) and to notify of unsatisfactory or dangerous conditions. Standardized colors are used to differentiate between visual messages, with green as a satisfactory condition, yellow for caution or a serious condition that needs monitoring, and red as a color for unsatisfactory or dangerous conditions.

An aircraft propeller consists of two or more blades mounted on a central hub connected via a shaft to the engine. This can be either an extension of the engine’s crankshaft in low-horsepower engines, or a propeller shaft geared to the crankshaft in high-horsepower configurations. In either case, each blade of the propeller essentially acts as a rotating wing, which produces force that creates thrust to pull or push the aircraft through the air. The vast majority of aircraft have a “tractor” arrangement, where the propeller is mounted towards the front of the fuselage and pulls the aircraft, but there are examples of “pusher” arrangements where the propeller is mounted in the back and pushes the aircraft through the air.

You can fold up a piece of paper, give it two wings, and watch it fly. However, you do not have the ability to pick where the paper plane lands or alter how fast it gets there. This is because you most likely did not add propellers to your paper plane. Two recognizable features of an aircraft are the wings and the aircraft propellers. Both of these parts allow the pilot to control the aircraft and navigate it through the skies. Aircraft wings and propellers each manipulate the air in which the aircraft is flying in. The wings, also known as airfoils, direct and redirect the airflow around the aircraft. The propellers are designed to produce thrust, thus, moving the plane forward.

Compressors reduce air volume and therefore increase its pressure. This device is utilized in engines to increase the amount of air allotted to the combustion chamber— the more air that can be added, the more an engine can burn and produce more power. An air compressor specifically compresses air, as opposed to other compressors that condense different types of gases. There are many types of compressors that have been developed for various applications, and new technology and designs have increased efficiency throughout the years.

Almost all modern turbine engine aircraft incorporate air compressors in their systems. Turbine engines use an air compressor to increase the pressure of incoming air before it enters the combustor. There are two types of air compressor used in aviation, axial and centrifugal.

It’s the new normal, to be able to fly from point A to point B, thousands of miles away, in a matter of hours. And yet, the mechanics of this “simple” act are still unknown to a vast majority of people. We take for granted all the advancements and innovations that it took to allow us to travel so far and so fast as regularly as we do. So, it makes sense that to the average person, “turbonormalizing” and “turbocharging” sound like they mean the same thing. Or they remind people of the Fast and Furious franchise. Surprisingly, that’s not entirely wrong.

Propellers are, single-handedly, the most noticeable part on an aircraft. Using energy from the engine to spin, the aircraft propeller is used to create thrust by rotation.

Depending on the type of aircraft, the propeller can look very differently. The number of blades increases as the size of the aircraft engine increases, to ensure proper power distribution. And, propeller blades can vary in material, such as wood, fiberglass, composites, and metals, depending on how strong or durable they have to be.
