Large-Scale Gust Generation Test Section for the Fejer Wind Tunnel
Abstract
A modification to the Fejer Unsteady Flow Wind Tunnel at Illinois Institute of Technology isproposed that will provide unique large-scale gust generation capabilities. The proposedmodification combines controllable cross-flow and longitudinal velocity components thatwill replicate naturally occurring gusts with fidelity never before achieved in a laboratory.The ability to create gusts with variable amplitude, frequency, and spatial wavelengths willmake it possible to explore the transient flow structures and energy exchange mechanismsthat occur around wings in large-amplitude gust fields, such as, gust-induced dynamic stallvortex development. This new gust-generation technology is a critical component to existingand proposed AFOSR sponsored research at UCLA/Caltech/IIT. The multi-universitycollaboration is studying the flow physics behind unsteady aerodynamics of gusting flows,and is developing low-dimensional models for practical flight vehicle control applications.The gust-generation facility will also enhance the research in an on-going ONR sponsoredgrant investigating the unsteady aerodynamics of a UCAV aircraft landing on aircraftcarriers.
