In this paper, work is presented that extends a concept for a novel aircraft roll control system considered in an earlier paper by the authors. The focus of this paper will consider principally the influence of acticulated winglets on the resulting surface pressures on a flying wing test model for possible applications to gust load alleviation. The experimental model tested, analysed, and evaluated used two actively controlled wingtips (one mounted at each wingtip) that were free to rotate about the wing-tip chord axis line. The model was also purpose build to allow for multiple dynamic surface pressure measurement on one upper wing surface to measure, under test conditions, the real-time aerodynamic changes during winglet actuation.
