Detailed Description

Blade model class calculates:

  • Linear interpolated blade twist and chord based on radial position
  • Interpolation factor (for interpolating profile performance)
Usage
Minimal example by using constant/fvOptions: rotorDiskSource1 { Mandatory/Optional (inherited) entries ...

Mandatory entries (runtime modifiable) blade { Mandatory entries (runtime modifiable) data ( (profile1 (radius1 twist1 chord1)) (profile1 (radius2 twist2 chord2)) ... ([0] ([1] [2] [3])) );

Optional entries (runtime modifiable) file <fileName>; } }

where the entries mean:

Property Description Type Reqd Dflt
blade Dictionary name: blade word yes -
data Blade characteristics in list format list yes -
[0] (profile) Corresponding profile name per section word yes -
[1] (radius) Radial position of the blade section [m] scalar yes -
[2] (twist) Twist angle of the blade section [deg] scalar yes -
[3] (chord) Chord length of the blade section [m] scalar yes -
file Name of file containing blade characteristics word no -
Note
  • The entry twist is internally converted from [deg] to [rad].
