Propellers
Propellers are rotating airfoils that produce thrust to propel an aircraft through the air. They convert the rotational energy from the engine into a forward thrust, which propels the aircraft forward. Propellers come in various shapes and sizes, and their design is dependent on the type of aircraft and its intended use. The pitch of the propeller blades can be adjusted to optimize the engine's performance at different altitudes and airspeeds. Propellers can be classified as fixed-pitch or variable-pitch, depending on whether the pitch can be adjusted in flight or not. Propellers are an essential component of most aircraft, including airplanes, helicopters, and some unmanned aerial vehicles (UAVs).
