Piaggio Aerospace, in collaboration with Von Karman Institute and SONACA, thanks to the funding received from the Clean Sky 2 Joint Undertaking (JU), designed and tested an innovative blowing flap high lift device within the frame of the MOTHIF project, in order to increase STOL aircraft capability to take off from runaway shorter than 800m. This paper aims to present comprehensively the results of the blowing high lift device wind tunnel test campaign conducted at VKI during Summer 2021, in comparison with CFD-based design data: the blowing jet and its influencing parameters effects on aerodynamic coefficients is exposed, especially regarding lift augmentation.
