Research
The main objective of the project DAVYD is to reduce the impact of flight vehicles on the environment both in terms of pollution and noise emissions according to the specialization areas (Aerospace), defined by PNR 2015-2020 and SNSI, and ACARE 2050 goals. The consortium DAVYD focuses on two aircraft components, and the application of innovative technologies will reduce noise and pollution. The two systems of interest are the electromechanical landing gear system and the control surfaces of an aircraft/fast rotorcraft. In both cases, the idea is to reduce the vehicle's CO2 and NOx emissions by modifying the component's weight and then achieve noise reduction. Furthermore, the identification of more eco-friendly materials and processes aimed at reducing material waste will be investigated to further reduce their environmental impact.
As a consequence, the project has two main aims: III.The development, up to TRL4, of novel control surfaces (CS) in hybrid metal-composite materials having low weight and high strength for tiltrotor applications. Activities of research and development concerning the material trade-off and characterization, conceptual studies (aeroelasticity), trial manufacturing and relevant experimentation (acoustic) will be performed. IV.The development, up to TRL4, of an Electro-mechanical Actuator (EMA) for landing gear system and related technologies. Both the actuators (including the locking mechanism) and the electronic control unit (ECU) will be based on 270 Vdc technology, allowing a substantial weight reduction with respect to the current state of art of low voltage actuators. These actuators will be developed and tested in laboratory. Thanks to these activities, the partners of the DAVYD project will be at the forefront of the application of improved and innovative processes in the aviation field by contributing in retaining Europe’s industrial leadership in the aviation field. In particular, these technological improvements will strengthen the capabilities of the Italian aeronautic industries such as Leonardo and Piaggio Aero industries. Moreover, this project will support the growth of technological competences and knowledge of the Southern Italy in the aeronautic field, as well as creating new job opportunities for young researchers/engineers coming from universities.
