This axes system positions the aerofoil relative to the reference axes. The origin is at the quarter-chord position, a quarter of the way from the leading edge to the trailing edge along the chordline. The X-axis of the system is parallel to the chordline, and the Y-axis perpendicular to it. If omitted, the reference axes will be used as the quarter-chord axes.

  • OffsetInReferenceX: number (m)
  • OffsetInReferenceY: number (m)
  • RotationAboutReferenceZ: number (rad)

Properties

OffsetInReferenceX: number (m), optional

The offset of the axis system origin from the reference axes in x.

default = 0.0

OffsetInReferenceY: number (m), optional

The offset of the axis system origin from the reference axes in y.

default = 0.0

RotationAboutReferenceZ: number (rad), optional

The rotation of the axis system's x and y axes around the reference z axis (the section plane normal).

default = 0.0
