This technical report concerns with experimental investigations carried-out at the CNR-INSEAN towing tank on oscillating 3D wings. The experimental campaign is aimed at characterizing the behavior of 3D translating and pitching wings, with different sectional shapes, in terms of unsteady hydrodynamic loads due to selected harmonic pitching laws. The main interest of the activity is on the dynamic stall onset that, if present, changes the hydrodynamic response of the wing respect to the stationary operating condition. For this reason, data analysis highlights the differences between steady and unsteady forces to define the operating conditions boundaries for each wing-type herein investigated. This document represents the Project Deliverable 2.0 in fulfillment to tasks 4-7 of Contract 05CT12.

Abstract
This technical report concerns with experimental investigations carried-out at the CNR-INSEAN towing tank on oscillating 3D wings. The experimental campaign is aimed at characterizing the behavior of 3D translating and pitching wings, with different sectional shapes, in terms of unsteady hydrodynamic loads due to selected harmonic pitching laws. The main interest of the activity is on the dynamic stall onset that, if present, changes the hydrodynamic response of the wing respect to the stationary operating condition. For this reason, data analysis highlights the differences between steady and unsteady forces to define the operating conditions boundaries for each wing-type herein investigated.
