Class
Foam::bladeModel
Description
Blade model class calculates:
Linear interpolated blade twist and chord based on radial position
Interpolation factor (for interpolating profile performance)
Input in list format:
data
(
(profile1 (radius1 twist1 chord1))
(profile1 (radius2 twist2 chord2))
);
where:
radius [m]
twist [deg], converted to [rad] internally
chord [m]
