  Different views of the GAD showing the forces and angles involved: Blade cross section showing the normal (:math:`V_n`) and tangential (:math:`V_t`) components of velocity with the normal (:math:`a_n`) and tangential (:math:`a_t`) induction factors, relative wind velocity :math:`V_r`, blade twist angle :math:`\xi`, angle of relative wind :math:`\psi`, blade pitch angle :math:`\phi`, lift (:math:`L`) and drag (:math:`D`) forces, and normal (:math:`F_n`) and tangential (:math:`F_t`) forces; top view showing the flow direction and inclination angle :math:`\Phi`; and front view showing the actuator disk rotating clockwise.
