The following list outlines the AVL inputs along with their default value available through the AIM interface.
- Mach = 0.0
Mach number.
- Alpha = NULL
Angle of attack [degree]. Either CL or Alpha must be defined but not both.
- Beta = 0.0
Sideslip angle [degree].
- RollRate = 0.0
Non-dimensional roll rate.
- PitchRate = 0.0
Non-dimensional pitch rate.
- YawRate = 0.0
Non-dimensional yaw rate.
- CDp = 0.0
A fixed value of profile drag to be added to all simulations.
- AVL_Surface = NULL
See Vortex Lattice Surface for additional details.
- AVL_Control = NULL
See Vortex Lattice Control Surface for additional details.
- CL = NULL
Coefficient of Lift. AVL will solve for Angle of Attack. Either CL or Alpha must be defined but not both.
- Moment_Center = NULL, [0.0, 0.0, 0.0]
Array values correspond to the Xref, Yref, and Zref variables. Alternatively, the geometry (body) attributes "capsReferenceX", "capsReferenceY", and "capsReferenceZ" may be used to specify the X-, Y-, and Z- reference centers, respectively (note: values set through the AIM input will supersede the attribution values).
- Lunit = 1 m
Reference length of the configuration for Eigen value analysis. The aircraft is scaled by this quantity
- Munit = 1 kg
Reference mass of the configuration for Eigen value analysis. Units must be specified. Values in the MassProp are scaled by this quantity.
- Tunit = 1 s
Time units for Eigen value analysis.
- MassProp = NULL
Mass properties used for eigen value analysis Structure for the mass property tuple = ("Name", "Value"). The "Name" of the mass component used for documenting the xxx.mass file. The value is a JSON dictionary with values with unit pairs for mass, CG, and moments of inertia information (e.g. "Value" = {"mass" : [mass,"kg"], "CG" : [[x,y,z],"m"], "massInertia" : [[Ixx, Iyy, Izz, Ixy, Ixz, Iyz], "kg*m2"]}) The components Ixy, Ixz, and Iyz are optional may be omitted.
- Gravity = NULL
Magnitude of the gravitational force used for Eigen value analysis.
- Density = NULL
Air density used for Eigen value analysis.
- Velocity = NULL
Velocity used for Eigen value analysis.
