This work demonstrates the viability of a novel transverse-gust generator that is capable of producing a controllable time-varying gust without increasing the turbulence level within a large region of the flow facility. The new gust generator concept is based on the utilization of a vortex-generator array (VGA) along one of the walls of a facility's test section at a given streamwise location. Using such a device, a step-like and a sinusoidal gust with an amplitude of 5.7% are demonstrated experimentally in a wind tunnel. A simplified vortex-array model is shown to be a useful tool for the design of the new gust generator.
