Riassunto analitico
The purpose of this thesis is to simulate the aileron maneuver of the reference wing using the piezoelectric material (MFC).The first part of the work talk about the experimental test of the torsion and bending specimens and the comparison of it with the FEM analyses (ANSYS). This specimens are manufactured in Dresden by SMG with a two different composite materials and in the both external surface are glued the piezoelectric material. The purpose of this study is to evaluate the displacement of the specimens under the voltage loads and calibrate the FEM model with the real model. In the document the FSI analysis of the NACA 0012 airfoil has been shown. These analyses have been used to realize the experimental wing section (FW-UNIT), it builts in Dresden by the partener SMG. The piezoelectric material has been glued on the nose and on the tail, in this way it was possible modificated the curvature of the airfoil. Afterwards the two dimensional FSI (Fluid Structure Interation) analyses have been done. The aileron-wing section model and the piezo wing one have been generated by ANSYS. Also in this case the piezoelectric materials have been bonded on the nose and on the tail. The results summarize the mechanical behavior of the wing section (the geometry of morphed section related to control parameters) and the aerodynamic performance (drag polar curves of the wing section for different level of voltages control and different altitudes and Mach numbers). The case analyzed refers to a reference wing based on the geometry of the assumed reference aircraft (the aircraft of the Piaggio Company that is the P180). The study is fully with a three-dimensional even if only half wing models have been analyzed. The results of this comparison reveals the the present technology shows good chances for future industrial implementation in the aerospace field.
