Display general information about the available Aero Classes. Setting | Description |
---|
Group, Aero |
Group and name of Aero Class |
RefCS: |
Cross section related to the Aero Class for calculation with CFD module |
Data, Sym |
Type of data and flag indicating if coefficients for - directions can be deduced from those of + directions
- Single Values: Only one coefficient and derivate is given per main direction
- Table: Several values can be given for each main direction
|
FactorX, FactorY, FactorZ |
Additional factors for steady state coefficients |
DragX, FIDx |
Drag coefficient for longitudinal wind and normalization length |

Structural Data Table
|
Display and modify structural data of selected Aero Class. Two lines are available for performing wind design checks. Setting | Description |
---|
eigenm. file |
Name of modal file to read, can be empty. |
VPos, TPos |
Number of lowest Eigenmode with mainly vertical/torsional displacement Note: Only evaluated if modal file name is given
|
Omega V, Omega T |
Vertical and torsional circular frequency |
Inertia V, Inertia T |
Generalized mass and moment of inertia |
Damping V, Damping T |
Damping ratio to critical for vertical/torsional Eigenmode |
Lever arm, GR |
Distance of center of mass and elastic center and radius of gyration
Note: Circular frequencies and generalized mass/inertia can either be read from a modal file or be given directly. The values given in modal file override those in the table.
