"WebThis three-bladed airscrew is designed for an aero engine of 1,009 horse-power. It has a diameter of 13 feet and weighs 360 lb. The pitch of the blades can be altered as required for take-off, climb, or high-speed level flight. The blades of an airscrew revolving at high speed form what is known as an airscrew disk.
