Adaptive aeroelastic structures for improved aircraft performance
This paper describes the latest developments in a research program investigating the development of “adaptive internal structuresto 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.
