[en] This paper describes the latest developments in a research program investigating the
development of “adaptive internal structures” to enable adaptive aeroelastic control of aerospace
structures. Through controlled changes of the second moment of area, orientation or position of
the spars, it is possible to control the bending and torsional stiffness characteristics of aircraft
wings or tail surfaces. The aeroelastic behaviour can then be controlled as desired. A number of
different adaptive internal structure concepts (rotating, moving and split spars) are compared
here using a simple rectangular wing structure in order to determine which are the most effective
for achieving minimum drag at different points in a representative flight envelope. A genetic
algorithm approach is employed to determine the optimal spar orientation for rotating spars
concept. It is shown that it is feasible to adjust the structure and trim characteristics of such wing
structures in order to achieve minimum drag at all conditions.
