Clean Sky 2, an innovative wing for the future TP90 regional aircraft of Leonardo


As part of the CLEANSKY2 REG IADP program, the experimental tests campaign in the DNW wind tunnel for the aerodynamic and performance validation of the wing design for the future TP90 regional aircraft of Leonardo was successfully completed in December 2021.

The aerodynamic design of the adaptive wing was created as part of the AirGreen2 project coordinated by CIRA. The wing was designed with extensive natural laminar flow and with innovative adaptive surfaces capable of optimizing aerodynamic efficiency in the different phases of flight. The adaptive surfaces consist of:

  • the flap morphing capable not only of performing the typical functions of take-off and landing but also those of optimizing the aerodynamic design during the cruise;

  • the winglet with 2 movable morphing surfaces for controlling the load on the wing, thus able to limit the disadvantages due to the presence of its mass at the wing tip while maintaining the advantages in terms of aerodynamic efficiency;

  • the deformable leading edge to ensure the maintenance of high aerodynamic efficiencies in the different phases of flight; as an alternative to the winglet;

  • the wingtip at the end of the wing equipped with a movable surface for the control and lightening of the gust load on the wing.

Airgreen2 contributed to the tunnel model (scale 1:3; span greater than 5 m) by creating the leading edges (Polimi, Tecnam), the winglet (Novotech, Tecnam), the flap morphing (Unina), the wingtip (Polimi).

CIRA (“Aeronautics Technology Integration" and “Adaptive Structures") coordinated the activities within the AirGreen2 consortium and managed the interactions with the GRETEL consortium (responsible for building the wing box and integrating the model), the ESTRO consortium (responsible for tunnel tests) and Leonardo.
