Concepts for the Actuation System of the Spacecraft Technology Vehicle SHEFEX 2

Stress distribution in the module by the torsion from the aerodynamic loads
The torsion moment transforms the cylindrical module into a regular "square" shape. The picture shows stress levels (by colour) and the magnified deformations, generated by the FEM analysis (finite element method). The highest stresses (yellow and red) occur between the actuators, because the actuators contribute to the stiffness of the thin structure.
