As part of the AIRGEEN2 Project of CLEANSKY2 REG IADP, the experimental ground tests campaign for the structural validation of the Morphing Flap for the the wing of the future TP90 regional aircraft of LEONARDO was successfully completed in July 2022 by NOVOTECH in its plant of Casoria (NA).
The morphing flap design was created as part of the CLEAN SKY2 AirGreen2 project coordinated by CIRA. The morphing flap detailed design was developed by UNINA and the full scale ground demo test article (5×0.35 m) was manufactured and tested by NOVOTECH. The morphing flap successfully completed all structural static and functionality tests.
The morphing technology was applied to the design of the flap in order to extend the use of the flap not only to the take off and landing flight segments but also during the cruise to obtain enhanced performance in terms of lift generation in take-off and landing and to adequately set the load distribution along the wing during cruise, thus minimising the stress level and enhancing the aerodynamic efficiency. The device in fact assures three different working modes: full camber variation in fully deployed configuration for hyper-lift purpose and combined and differential deflection of the tabs along the span in retracted configuration to control the distribution of load.
