LocalAngleOfAttack:

Path: ACPro/ACProAerodynamics

--------------------------------------------------------------------------
   Compute the local angle of attack.

   The surface rotates by an angle delta about a body axis aB. The
   freestream velocity direction in the body frame is assumed to be: 

     vDirB = [-cos(alpha);0;-sin(alpha)]

   Since version 2014.1
--------------------------------------------------------------------------
   Form:
   alphaE = LocalAngleOfAttack( alpha, aB, delta )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   alpha     (1,1)   Angle of attack (rad)
   aB        (3,1)   Unit axis vector of control surface for rotation
   delta     (1,1)   Angle of rotation about axis (rad)

   ------
   Outputs
   ------
   alphaE    (1,1)   Effective or local angle of attack at the plate.
