Aerodynamic Evaluation

This chapter is devoted to the aerodynamic evaluation to experimentally investigate first the flow structure and the morphing effects on the tRS (transonic Reduced Scale) prototype of 15 cm chord, and secondly to evaluate the impact of the optimal morphing cambering on the LS (Large Scale) prototype in respect of the aerodynamic performance increase. The first part concerning the transonic regimes involves morphing through optimal trailing edge region vibration performed in the wind tunnel of IMP-PAN concerning cruise phase conditions and the second investigates the aerodynamic perfomance through cambering of the high lift flap of 1 m chord and 2 m span, emebedded in the fixed wing configuration of 4 m span in the POLIMI’s wind tunnel in take-off and landing conditions.
