Detailed Description

Low speed aerodynamic model. The organization of the data file is

• m Number of models

[ x;y;z ] Rotation axis of model

• [ x;y;z ] Location of model with respect to the reference

If the rotation axis is [0;0;0] then the model is assumed not to rotate relative to the core body.
