The project proposal concerns the challenges posed by the physical integration of smart intelligent
structural concepts. It addresses aircraft weight and operational cost reductions as well as an
improvement in the flight profile specific aerodynamic performance.
This concerns material concepts enabling a conformal, controlled distortion of aerodynamically
important surfaces, material concepts enabling an active or passive status assessment of specific
airframe areas with respect to shape and potential damages and material concepts enabling
further functionalities which to date have been unrealizable.
Past research has shown the economic feasibility and system maturity of aerodynamic morphing.
However, few projects concerned themselves with the challenges arising from the structural
integration on commercial aircraft. In particular the skin material and its bonding to the substructure
is challenging. It is the aim of this project proposal to demonstrate the structural
realizability of individual morphing concepts concerning the leading edge, the trailing edge and the
winglet on a full-size external wing by aerodynamic and structural testing.
Operational requirements on morphing surfaces necessitate the implementation of an independent,
integrated shape sensing system to ensure not only an optimal control of the aerodynamic surface
but also failure tolerance and robustness. Developments made for structural health monitoring will
be adapted to this task. Similar systems optimized for rapid in-service damage assessment have
progressed to a maturity which allows their inclusion in the next generation of aircraft. However,
the time consuming application of these sensor systems has to be further improved by integration
at the component manufacturing level. The additional benefit of a utilization of these adapted
systems for part manufacture process and quality control shall be assessed in SARISTU.
Addressing the Nanotechnology aspect of the call, benefits regarding significant damage tolerance
and electrical conductivity improvements shall be realized at sub-assembly level.
