Abstract:
A topical issue in atmospheric science is to find ways to detect and predict clear-air turbulence (CAT). CAT is a physical phenomenon produced by the turbulent movements of air masses in cloudless areas that has potentially disastrous consequences for aircraft and/or passengers, being undetectable by the on-board equipment. In this paper, a new approach of the CAT attenuation methodology is proposed based on active control. The experimental model is represented by a realistic, elastic wing with aileron controlled by an electric linear servoactuator. Numerical simulations and experiments in the subsonic wind tunnel upgraded with a turbulence generator were performed.
