AESURF

Bulk Data Entry Specifies an aerodynamic control surface as a member of the set of aerodynamic extra points. The forces associated with this controller will be derived from rigid rotation of the aerodynamic model about the hinge line(s).

Comments

  1. The ID on AESURF and AESTAT entries are ignored.
  2. The degrees-of-freedom defined on this entry represent a rigid body rotation of the control surface components about their hinge lines.
  3. Either one or two control surface components may be defined.
  4. If EFF is specified, then the forces produced by this surface are modified by EFF (as in, to achieve a 40% reduction, specify EFF=0.60).
  5. The continuation line is not mandatory.
  6. The CREFC and CREFS values are only used in computing the non-dimensional hinge moment coefficients.
