Reference values used by VSAero for aerodynamic computations. If this node is created automatically by the tool's input mapping ( Framework integration mode), the selected aircraft model's common reference length is used for <lengthCMXCMZ> and <lengthCMY>. If this node is created manually (for Toolwrapper input mode), the CPACS-Outputfile uses <lengthCMY> as common reference length.
This is the reference area, used to calculate all the aerodynamic coefficients.
This is the reference length, used to calculate all the rolling and yawing moment coefficients (C Mx and C Mz ).
This is the reference length, used to calculate all the pitching moment coefficients (C My ).
This is the reference point in (global coordinate system), used for all moment computations. It further is origin of the three axis' for quasi steady rotation calculations. VSAero itself always uses the origin of the global coordinate system as origin for the quasi steady rotations. Hence, for the VSAero computation, the whole aircraft model is moved in a way, so that the <momentReferencePoint> is located at the origin [0,0,0] of the global coordinate system. The results are transformed back into the CPACS coordinate system afterwards.
