*3.2. Evaluation Criteria*

In order to compare the alternative morphing technologies and their integration options, a set of relevant evaluation criteria should be chosen. By considering the main advantages and challenges for such architectures, the following criteria have been selected:


Improvements in flight performance represent the primary reason for the consideration of morphing wing structures in the first place. Evaluations according to this criterion should reflect the difference in aerodynamic qualities, flight stability, integration of innovative flight controls, etc. However, a trade-off should be made with the energy required for different morphing modes and morphable wing areas, making it a second criterion. Last but not least, the MM options should be compared according to their system complexity and weight in order to round-up the subject-relevant main global aspects.

For the purpose of easier results interpretation, the criteria will not be weighted for the final solution evaluation.
