A vortex generator is useable in a model in a fluid-dynamic channel. In order to save time during the development of vehicles, in particular, aircraft, to save wind tunnel time, it is suggested to configure the vortex generator to be switchable. A switchable vortex generator can be used, in particular, on models in fluid-dynamic channels and in fluid-dynamic channel tests.

1. A vortex generator for generating vortices, the vortex generator comprising: a vortex generating element, switchable between at least two stable switching states, such that the vortex generating element maintains each stable switching state without energy input; anda bistable biasing component configured to contact the vortex generating element to enable switching of the vortex generating element between the stable switching states by an energy impulse. 2. The vortex generator according to claim 1, wherein the bistable biasing component comprises at least one force generator chosen from the group comprising a magnetic force generator, an electrostatic force generator, an electrodynamic force generator, a mechanical elastic element and a mechanical spring. 3. The vortex generator according to claim 1, wherein the bistable biasing component includes a first magnet for holding the vortex generator in a first stable switching state and at least one second magnet for holding the vortex generator in a second stable switching state. 4. The vortex generator according to claim 1, wherein the biasing component includes at least one bistable spring element. 5. The vortex generator according to claim 1, wherein the vortex generator is switchable between the two stable states by the application of an external force. 6. The vortex generator according to claim 1, wherein at least one magnet element is associated to the biasing component to switch the biasing component from one of the stable states to the other of the stable states by applying an external magnetic field. 7. The vortex generator according to claim 1, further comprising an actuator membrane moveable between at least two positions to switch the vortex generator between the at least two stable states. 8. The vortex generator according to claim 1, wherein the switching mechanism includes at least one actuator from a group of actuators comprising electromagnetic actuators, piezo-electric actuators, electrostatic actuators, pneumatic actuators, hydraulic actuators, permanent-magnetic actuators and thermoelectric actuators. 9. The vortex generator according to claim 1, further comprising a covering membrane having a smooth surface, against which a flow to be influenced by the vortex generator can flow. 10. The vortex generator according to claim 1, further comprising a switching mechanism configured to switch the vortex generator between an ON state and an OFF state. 11. The vortex generator according to claim 10, wherein the switching mechanism is signal-controlled.
