The term AIRSCREW is a combination of two words, AIR and SCREW. An airscrew is a type of PROPELLER used to generate thrust for aircraft. It consists of two or more blades that rotate around a central hub, creating a rotating column of AIR that propels the aircraft forward. The blades are usually made of metal, but can also be made of composite materials such as carbon fiber. The airscrew is an essential part of any aircraft, providing the necessary thrust to keep it in the AIR.
