Zusammenfassung:	A cavity system is provided. The cavity system (100-600) comprises: a cavity (2) and a spoiler (104-604); and the spoiler (104-604) having a front surface and a rear surface. The spoiler (104-604) is positioned in proximity to a leading edge (14) of the cavity (2), the leading edge (14) being relative to an actual or intended flow direction (3) of a fluid over the cavity (2). The spoiler (104-604) is arranged with its longitudinal axis perpendicular or at an oblique angle to the actual or intended flow direction (3) such that the front surface faces towards the flow direction (3). A first region of the spoiler (104-604) extends further toward the leading edge than a second region of the spoiler (104-604).
