Fixed-pitch propellers are used on airplanes of low speed, power, altitude, or range. Any change in those conditions reduces both the propeller and engine efficiency. They fit a specific set of conditions of both engine and airplane speed. These propellers are designed to provide the best efficiency at forwarding speeds. Fixed-pitch propellers are generally one piece and made of aluminum alloy or wood. Once the propeller has been built, the blade angle can’t be changed.
The propeller that has the blade angle or blade pitch made into the propeller is categorized as a fixed-pitch propeller.
We will look at some of the most common types of aircraft propellers and see how they are different from one another.
There are different types of aircraft propellers available today. Propellers are an essential part of the aircraft as without them an airplane cannot fly. The device that converts rotational energy generated by the engine or any other mechanical source into propulsive force is called a propeller.
