1. An active twist hollow beam system comprising:

  • a hollow beam having a first end attached to an external structure, the beam being split along a longitudinal length of the beam; and

    an actuator arranged to move split surfaces of the beam in a longitudinal direction relative to each other along the longitudinal length of the beam, inducing a twist in the beam,the system configured such that the actuator moves the split surfaces in the longitudinal direction relative to each other,wherein a cross section of the first end has a plurality of zero-warping displacement locations and maximum warping displacement locations between the zero warping displacement locations,the first end being attached to the external structure at the zero-warping displacement locations and being free of attachment to the external structure at the maximum warping displacement locations.
