Abstract

A gust encounter over a flat plate was investigated with a focus on partial chord integration. A transverse gust generator was designed for use in a water tunnel with towing capabilities. Utilizing a GR = 0.5 at a Reynolds number of 10,000, pitching was executed to counteract the gust loading. Employing different integration lengths to evaluate the effective angle of attack needed to pitch, four pitching models were studied 0% to 50% chord, 50% to 100% chord, 25% to 75% chord, and 0% to 100% chord. Force studies demonstrate that taking the full integration length is the best case being able to mitigate 71.28% of the induced lift from the gust. However, in terms of mitigating the drag, integrating 25% to 75% of the chord length resulted in the best case at 15.66% drag mitigation induced by the transverse gust. Furthermore, integration lengths that occupy more than the full chord lengths were studied and found to be more effective than taking the full chord as the integration bound due to the deformation of the gust’s shear layer.
