Load type > Mean pitch

Definition of the pitching moment due to wind loading across the element axis (wind direction normal to the axis) (m = cp * Rho * v^2 / 2).

SettingDescription
From, To, Step Element series to be loaded
Assembly Alternative to load assignment via element series: Name of the assembly to be loaded. The specified load is applied to every element of the specified assembly.
Rho Air density (tons per volume unit)
Note: No default value. The density must be explicitly specified. (Value appr. 0.00125 t/m^3; mass unit always tons t, cannot be changed)
Alpha Attack angle (angle of incidence, angle between the local z-axis of the element and the wind direction, positive from +z to the wind direction in direction +y
Note: Loads in negative z-direction may be modeled either by defining an  attack angle of 180° or by specifying a negative drag coefficient
v-beg Wind velocity at element begin
v-end Wind velocity at element end
Note: The load intensity is calculated for the element begin and element end, and then applied as linearly distributed torsional moment load.
cp Pitch coefficient (positive, if the moment turns from +z to +y)
cd' Derivation of drag coefficient with respect to alpha (irrelevant for static loading).
Options: None, Mult. by CS width, Mult. by CS depth
  • None: Area included in the pitch coefficient (m = cp * Rho * v^2 / 2)
  • Mult. By CS width: Pitch coefficient related to the cross-section width b (m = cp * b * b * Rho * v^2 / 2)
  • Mult. By CS depth: Pitch coefficient related to the cross-section depth h (m = cp * h * h * Rho * v^2 / 2)
