VORTEX GENERATOR ARRANGEMENT, FLOW CONTROL SYSTEM AND METHOD FOR CONTROLLING A FLOW ON A RUDDER SURFACE

摘要

Described and claimed is a vortex generator arrangement for an aircraft comprising a surface section forming a flow surface interacting with a flow surrounding the aircraft in operation, wherein the surface section comprises an opening, a vortex generating means movable between a retracted position and an extended position, a retaining means for holding the vortex generating means in the retracted position, a biasing means for biasing the vortex generating means towards the extended position and a release means for releasing the vortex generating means from the retaining means such that the vortex generating means can be moved towards the extended position. Further, a sealing membrane is provided completely sealing the opening when the vortex generating means is in the retracted position. The vortex generating means is movable through the membrane from the retracted position to the extended position. Furthermore, a flow control system, an aircraft and a method of controlling flow are described and claimed.
