In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed (RPM), and the blade pitch is controlled automatically wit… WebDescription. Blade pitch, often shortened to pitch, refers to the angle between the propeller blade chord line and the plane of rotation of the propeller. Blade pitch is most often described in terms of units of distance that the propeller would move forward in one rotation assuming that there was no slippage. "Fine" pitch refers to a fine or ...

WebElectrically controlled constant speed propeller. The electric variable pitch propellers named ELCOPROP® are certified as 2-, 3- and 4-blade propeller models for engines producing up to 350 hp. Feathering capability can be integrated optionally, reverse capability can be integrated for the use on airships, only. Therefore, most propellers use a variable pitch mechanism to alter the blades' pitch angle as engine speed and aircraft velocity are changed. A sailor checks the propeller of a Landing Craft Air Cushion hovercraft A further consideration is the number and the shape of the blades used. See more An aircraft propeller, also called an airscrew, converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating … See more Lowry quotes a propeller efficiency of about 73.5% at cruise for a Cessna 172. This is derived from his "Bootstrap approach" for analyzing the performance of light general … See more Counter-rotating propellers are sometimes used on twin-engine and multi-engine aircraft with wing-mounted engines.
