These elements are not labeled on the propeller. The Rake measurement indicates the angle of blades’ tilt towards or away from the gear case. A propeller with 0 degree rake has blades 90 degrees perpendicular to the center of the hub. A 20 degree rake results in a blade that is angled 70 degrees from the hub.

Det låter som du behöver gå ned 2" i stigning på propeller. Har du dock en stålpropp med rake och cup så kan det gå att hissa så högt att

1.3 Propeller Geometry: Skew, Rake, and Cup Reference Figures 1.3A and 1.3B for the following terms. No. TERM DEFINITION 1.* Rake The fore or aft slant of a blade with respect to a line perpendicular to the propeller axis of rotation. 1a. Aft Rake Positive Rake. Blade slant towards aft end of hub.

En rake gör att formen på bladet blir till en kon, detta göra att vattenstrålen som bildas koncentreras istället för att spridas ut. En positiv/ökande rake lyfter stäven uppåt, detta ger en högre toppfart och även ett bättre grepp i vattnet. Rake.

Consequently, a propeller with high rake shifts the crucial limit where ventilation phenomena in higher trim angles appear, producing actually more thrust where other propellers cannot. Moreover, since it takes better advantage of the limited amount of water, the bow functions better in trimming, rises more, having as a final result the increase of our final speed.

Propeller Rake Propellers are all variations of helical forms, the pitch being the helix or distance that a blade would advance through a solid medium in one revolution. Thus a three bladed propeller can be thought of as three similar profiles each cut from the flight of a triple thread screw.

The paper describes an investigation of the performances of a tip rake propeller recently chosen as benchmark by the International Towing Tank Conference organization (ITTC hereafter). Propeller Selection Guide What to Consider When Shopping for a Propeller PAC Customer Service 1-800-888-4662 3 What to Consider When Shopping for a Propeller Several characteristics affect how a propeller will perform. Especially important are propeller diameter, pitch, rake, and cup.

The rake angle can be flat, staying the same along the entire blade, or progressive, meaning the angle increases as it approaches the tip.

method for the design of heavily loaded marine propellers with rake and skew along the propeller's blade via variational method, presented by Coney [9]. High rake propellers tend to lift the bow of the boat. On fast, lightweight,.

A greater rake angle generally improves the ability of the propeller to operate in a ventilating situation. Ventilation occurs when blades break and re-enter the water’s surface — such as occurs with 1) a Bravo sterndrive ( XR , XR Sport Master or XR Sport ) installed with a high “X” dimension, 2) a surfacing drive ( M6 or M8 ) or 3) an outboard installed or jacked high on a transom.
