Abstract
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).
Claims20
A cavity system, comprising:
- a cavity and a spoiler;
- and
- the spoiler having a front surface and a rear surface,
- wherein the spoiler is positioned in proximity to a leading edge of the cavity, the leading edge being relative to an actual or intended flow direction of a fluid over the cavity, the cavity having a pair of longitudinal edges, where at least a portion of the front surface continuously extends from one of the longitudinal edges in the pair of longitudinal edges to the other one of the longitudinal edges in the pair of longitudinal edges,
- wherein the spoiler is arranged with its longitudinal axis perpendicular or at an oblique angle to the actual or intended flow direction such that the front surface faces towards the flow direction, and
- wherein the front surface is non-planar.
