The following variables and equations are included to help describe the specialized coordinate systems used by BladeGen.
| 
 Z  | 
 =  | 
 Axial location.  | 
| 
 R  | 
 =  | 
 Radius or radial location.  | 
| 
 q or Theta  | 
 =  | 
 Rotation around Z axis from X towards Y axis (right hand rule).  | 
| 
 b or Beta  | 
 =  | 
 Blade Angle, measured from the axial or tangential direction. Internally, BladeGen always uses the axial definition.  | 
| 
 S  | 
 =  | 
 Fractional distance along a curve (between 0 and 1).  | 
| 
 M  | 
 =  | 
 Distance along meridional curve.  | 
| 
 M’ or M-Prime  | 
 =  | 
 Radius normalized distance along meridional curve.  | 
| 
 C  | 
 =  | 
 True 3D distance along camberline (meanline).  | 
| 
 q’ or Theta-Prime  | 
 =  | 
 Terminology given to describe the integral of R*dTheta. (See equations below)  |
