propeller for which the angle of the blades is adjustable

A variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. This adjustment allows the propeller to maintain optimal aerodynamic efficiency under varying flight conditions such as changes in speed, altitude, and aircraft load. The ability to alter the pitch provides improved performance over a wider range of conditions than constant-pitch propellers.
