A numerical and experimental investigation is described considering the design, manufacture and test of tow-steered composite wind tunnel wings. The generic construction of each wing consisted of a rectangular flat plate with foam aerofoil surfaces. Tow-steered composite layers of the wings were manufactured using two different techniques: Continuous Tow-Shearing and Discrete Stiffness Tailoring. Finite Element models of the wings were optimised in order to determine the tow-steered composite layer orientations, as well as unidirectional composite orientations, that reduced the maximum strains due to equivalent “manoeuvre” and “gust” loads (at a tunnel speed of 20 m/s). A series of static and dynamic, wind-on and wind-off tests were performed to validate the numerical modelling capability and to illustrate the capabilities of tow-steering technologies.
