Abstract

The Active Aeroelastic Test Bench (AATB) is a novel wind tunnel test setup that used higly dynamic electric linear actuators to command the pitch and plunge position of a cantilver wing. For the presented study the AATB is used to study the level of nonlinearities in the response of a cantilever wing to enforced 1-cos gust motion as well as multisine experiments. The cantilever wing being studied in the AATB is equiped with accelerometers and optical Fibre Bragg Grating (FBG) strain sensors. Measurements in the linear aerodynamic regime at small angles of attack, as well as at large angles of attack are studied and compared. It is illustrated how the Best Linear Approximation (BLA) can be estimated from multisine experiments using the Local Polynomial Method (LPM) as a first step to the modeling of the nonlinear aeroelastic response from wind tunnel tests.
