AirshipInertiaFactors:

Path: Airships/Modeling

% Compute the added mass/inertia factors for an airship hull.

   A double ellipsoid geometry is assumed. 
   For a single ellipsoid, a1 = a2.
--------------------------------------------------------------------------
   Form:
   [k1, k2, kp] = AirshipInertiaFactors( a1, a2, b );
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   a1          (1)       Semi-major axis of front ellipsoid   [m]
   a2          (1)       Semi-major axis of rear ellipsoid    [m]
   b           (1)       Semi-minor axis of each ellipsoid    [m]

   -------
   Outputs
   -------
   k1          (1)       Coefficient of added mass, axial
   k2          (1)       Coefficient of added mass, normal
   kp          (1)       Coefficient of added inertia, rotational
