Structure for the Vortex Lattice Control Surface tuple = ("Name of Control Surface", "Value"). "Name of control surface defines the name of the control surface in which the data should be applied. The "Value" must be a JSON String dictionary (see Section \ref jsonStringVLMSection). @section jsonStringVLMSection JSON String Dictionary If "Value" is a JSON string dictionary (e.g. "Value" = {"deflectionAngle": 10.0}) the following keywords ( = default values) may be used:

• deflectionAngle = 0.0
  Deflection angle of the control surface.

• leOrTe = (no default)
  Is the control surface at the leading or trailing edge?

  • For leOrTe = 0, the control surface is always between the leading edge and the hinge line.
  • For leOrTe = 1, the control surface is always between the trailing edge and the hinge line.

  The default behavior when leOrTe is not specified: If the hinge location percentage along the airfoil chord is < 50% a leading edge slat is assumed, while >= 50% indicates a trailing edge flap.

• controlGain = 1.0
  Control deflection gain, units: degrees deflection / control variable

• hingeLine = [0.0 0.0 0.0]
  Alternative vector giving hinge axis about which surface rotates

• deflectionDup = 0
  Sign of deflection for duplicated surface

Single Value String

If "Value" is a single string, the following options maybe used:

• (NONE Currently)
