Design and validation of a forced motion variable stiffness aerolastic wind tunnel set-up

Research output: Chapter in Book/Report/Conference proceedingConference paper

Abstract

The Active Aeroelastic Test Bench (AATB) is designed for the study of low subsonic unsteady aerodynamics and aeroelasticity. The AATB is equipped with four linear motors offering separate control of the pitch and plunge position of the wing. The AATB allows to perform forced motion unsteady aerodynamic experiments when operated in open loop. In addition, when operated in closed loop, aeroelastic experiments can be performed, with both linear, or nonlinear variable structural behaviour. For this closed-loop operation the directly measured loads are fed back to the real-time controller. This controller then outputs the user desired position, emulating structural behaviour of the wing.
