SHAFT ANGLES |
|
|
|
|
In addition to aperture size, shaft angle affects the maximum propeller diameter. The higher the shaft angle for a given engine location, the further below the hull bottom the propeller shaft will emerge from its bearing. Thus, the greater the propeller diameter can be. This is a particularly important on twinscrew crafts. In
a new design, or in any major refit and repowering, some thought
should be given to the possibility of increasing diameter by increasing
shaft angle, within reasonable limits. |
