Indroduction
• One of the fundamental drivers of the aerospace,
is research and technology development (R&TD).
• Growth of the most successful aerospace firm is
directly linked to investment in R&TD that leads
to successful product commercialization.
• For the industry to remain successful and grow,
there will need to be sustained investment in
product and process innovation.
• Piaggio Aero Industries has continue to invest in R&D tosustain the growth

• Develop Aerodynamics and Structural Simulation tool for wing design and Aero data generation.
• The purpose of the methodology is to run CFD coupled with computational structural model (FEM) in order to optimize the wing aero-shape taking into account the aeroelastic deformation

• Computational simulation of ice accretion is a key tool in the design, development and qualification or certification of aircraft for flight into known icing conditions;
• To reach this goal currently Piaggio Aero is involved in use Navier-Stokes solvers CFD++ were run with these conditions to generate a flow-field for input into 2D code (Multiice) to a collection efficiency and ice shape cuts;
• Ice shape cuts were used to produce lofts for aero performance degradation (both numerical and wind tunnel).
