Vortex generator, associated vortex generating system, aircraft and method of improving aerodynamic performances

Abstract

A vortex generator for an aircraft. The generator includes a base configured to be connected to an external surface of an aircraft, a baffle being connected to the base and moveable in rotation around a rotation axis relative to the base, and an actuator configured to move the baffle in rotation around the rotation axis relative to the base. The actuator is controllable into at least one active configuration in which the actuator is moving the baffle to a predetermined active position relative to the base and a passive configuration, in which the actuator is allowing rotation of the baffle relative to the base. The baffle is in a feathered position relative to the base when the actuator is in its passive configuration.
