bool BladeLayerData( int nBlade, int nLayer, uint uiFlags, BgMLDatArr &DatArr ); Description: Creates a mean line data array for the specified blade at the specified layer.

bool ExBladeLayerData( int nBlade, int nLayer, uint uiFlags, BgMLDatArr &DatArr ); Description: Creates a extended mean line data array for the specified blade at the specified layer. Data extends from inlet to outlet. Extensions have a thickness value of zero.

double MidLenSpanFraction( int nLayer ) const; Description: Returns the mid length span fraction for the specified layer.

bool AreaProps( int nBlade, int nLayer, BgMLDat &mldCentroid, double &dArea ); Description: Defines the centroid and airfoil area of the specified blade at the specified layer. Returns true if successful, false if unsuccessful.

double PitchFraction( int nBlade ) const; Description: Returns the pitch fraction for the specified blade.

EndType BladeLeEndType( int nBlade ) const; Description: Returns the type of end on the leading edge of the specified blade.

EndType BladeTeEndType( int nBlade ) const; Description: Returns the type of end on the trailing edge of the specified blade.

int NumLePoints( int nBlade, bool bExtended=false ) const; Description: Returns the number of points in the leading edge of the specified blade. If bExtended is set to true, the number reflects the effect of the extension (if it exists).

int NumTePoints( int nBlade, bool bExtended=false ) const; Description: Returns the number of points in the trailing edge of the specified blade. If bExtended is set to true, the number reflects the effect of the extension (if it exists).

bool PntAt( const double &dU, const double &dV, double &dZ, double &dR ); Description: Determines the meridional coordinate (Z,R) for the meridional position (U,V). Returns true if successful, false if unsuccessful. Input: const double &dZ, const double &dR. Output: double &dU, double &dV.

bool CoordAt( const double &dZ, const double &dR, double &dU, double &dV ); Description: Determines the meridional position (U,V) for the meridional coordinate (Z,R). Returns true if successful, false if unsuccessful. Input: const double &dZ, const double &dR. Output: double &dU, double &dV.
