Did planes have wooden propellers?
Until the mid-1920s, wood propellers turned the power of the aircraft engine into thrust to propel aircraft forward. They featured a permanently set blade angle, called fixed-pitch, and were made from layers of wood. After that, small general aviation aircraft relied upon them for thrust. …
What were the airplanes used in ww1 made of?
Airplanes in 1914 were not like airplanes today. They were not made of metal. The earliest airplanes had stitched canvas stretched over a wooden frame. The canvas was then painted to reduce drag and help pilots recognize planes from their own country.

The reason for wooden propellers was that the airplane manufacturers did not possess the ability, skill and technology to make metal propellers. Generally speaking, every airplane from the WW1 era was made from wood and covered in fabric.
How to identify wooden aircraft propellers?
The positive identification of wooden aircraft propellers can be frustrating, time consuming, and often very difficult. Positive identification of usage is made by correlation with a drawing number (also called design number, serie no., etc.) that was stamped on the propeller at the time of manufacture.
Why was wood used to build airplanes?
Wood was the material of choice for aircraft construction into the 1930s. Part of the reason was the slow development of strong, lightweight, metal aircraft structures and the lack of suitable corrosion-resistant materials for all-metal aircraft.
