fixed-pitch propeller

A fixed-pitch propeller is a type of propeller used in aircraft. It functions as a rotating airfoil, generating thrust by moving air. The blade angle on these propellers is set for a single flight condition, which limits their overall performance. While some fixed-pitch propellers can be adjusted on the ground for better performance in a specific flight phase, they lack the flexibility of variable-pitch propellers that allow pilots to adapt to different flight conditions like takeoff or cruising. The primary purpose of any propeller, including fixed-pitch ones, is to produce thrust and propel a vehicle, such as an airplane, forward.12
