Study Notes
Propeller Components
- A propeller consists of two primary components: blades and hub.
- Blades have various sub-parts that contribute to the efficient functioning of the propeller.
Blade Components
- Leading Edge: the cutting edge of the blade that faces forward when the propeller is spinning.
- Trailing Edge: the rear edge of the blade opposite the leading edge.
- Suction Face: the backside of the blade facing away from the direction of travel, pulling water into the propeller.
- Pressure Face: the front side of the blade pushing water out of the propeller, producing thrust.
- Root: the thicker base of the blade where it meets the hub.
Hub Components
- Shank: the thickened portion of the blade nearest the hub, also known as the root.
- Tip: the outermost point of the blade furthest from the hub.
- Blade Stations: reference lines marked on the propeller blade, usually measured in inches from the hub.
- Hollow Space: the space between the blades and the hub, allowing water to pass through freely.
Types of Propellers
- Propellers are classified as left-handed or right-handed based on the direction of water flow produced when the propeller rotates clockwise viewed from above.
- Left-hand propeller: rotates counterclockwise while spinning on the shaft.
