Abstract

A detailed performance investigation of the gust generator built for the Open Jet Facility wind tunnel at TU Delft is summarised in this paper. The influence of various parameters such as reduced frequency, measurement location, and excitation amplitude on the generated gust profile was quantified. In addition, unsteady lift measurements were performed using a rigid wing exposed to various gust profiles. In addition, unsteady incremental lift was compared with the DLM method which showed good agreement.
