Abstract

The paper presents the design, development and experimental validation of the MODular aeroelastic FLEXible wing for wind tunnel tests known as MODFLEX. It consists essentially of a single aluminium alloy spar (load-carrying flexible beam) and four separate aerodynamic sectors, separately connected to the main spar at a single point. The design allows for three active-sector configurations with the purpose of achieving a specified flutter velocity. In support of the design, a finite element (FE) model is described with coupled aerodynamic panels to solve the unsteady aerodynamic using the doublet lattice (DL) method. Active pole placement using the receptance method (RM) is carried out in real-time in a dSPACE environment to increase the flutter velocity by 12%. Experimental tests, carried-out in the wind tunnel facility at the University of Liverpool, are described.
