| 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)) | |
| (profile2 (radius2 twist2 chord2)) | |
| ); | |
| where: | |
| radius [m] | |
| twist [deg], converted to [rad] internally | |
| chord [m] | |
