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.

Switchable vortex generator and array formed therewith, and uses of the same

An aircraft passenger seat has at least one seat element characterized by at least one monitoring apparatus for monitoring the seat element. The seat arrangement has a plurality of seats, wherein at least one seat includes at least one sensor module for monitoring a seat element and a control unit for checking and controlling the monitoring, wherein the at least one sensor module is in a data exchange relationship with the control unit.

The invention relates to a vortex generator (), in particular for a model () in a fluid-dynamic channel. In order to save time during the development of vehicles, in particular aircraft, in particular to save wind tunnel time, it is suggested to configure the vortex generator () switchable. Further, the invention relates to various uses of such a switchable vortex generator (), in particular on models in fluid-dynamic channels and in fluid-dynamic channel tests.

A rate of rotation sensor is suggested which is structured out of silicon (silicon compounds or silicon/glass compounds) or other semiconductor materials by means of micromechanical techniques. The rate of rotation sensor has the form of a tuning fork whose prongs are situated in planes in parallel to the surface of the semiconductor wafer. These prongs are exited to carry out vibrations in a plane perpendicular to the wafer plane. By means of a sensor element which registers the torsion of the tuning fork suspension, the angular velocity of a rotation of the sensor about an axis in parallel to the tuning fork suspension is measured.
