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]
