Crystal Ball is a Propeller Component
Effect Facility (PCEF).
The components of a propeller can
be set and adjusted individually, Crystal Ball then calculates
the component change effect
. Multiple components can be changed simulatiously showing
the effect on the propeller’s pitch and RPM.
- DISK AREA RATIO
- PITCH SPAN
- SECTION SHAPE
Display Effective Pitch
Based on the added or included component effect the effective pitch
is calculated and displayed against the measured pitch as a value
also in bar graph form.
Display RPM Change
Based on the added or included component effect the effected RPM is
calculated and displayed against the actual RPM as a value and also
in bar graph
Display Percentage Change
Based on the added or included component effect the percentage change
of the effective pitch and effected RPM is displayed against the
measured pitch and actual RPM.
Display Cup Height
The actual dimension of the cup height is displayed based on the propeller
diameter and the cup component value.
Calculate Required Pitch
After all components values are adjusted and combined the required
RPM is keyed in and the required pitch is calculated and displayed
on the combined component effect.
