A fluidic oscillator device, in particular for a or in a flow control system for an aircraft or spacecraft, has a first and a second fluidic actuator, wherein each of the actuators has an inlet for supplying pressure and a first and a second outlet, from which an actuator flow can be discharged. The device further has a fluidic control for controlling an oscillating discharge of the actuator flow from the first and second outlet of the actuators, wherein the control has a connection portion which is arranged between the first actuator and the second actuator.

Aircraft or spacecraft fluidic oscillator device

An actuator assembly is capable of manipulating a fluid flowing around a flow body, the fluid being received or able to be received in a volume of at least one cavity arranged in the flow body, and the fluid passing through at least one opening in the at least one cavity during manipulation of the fluid. In this process, the volume of the at least one cavity can be changed by moving a wall portion delimiting or defining the cavity. The actuator assembly has a drive unit with at least one actuator, which executes a periodic movement over time when actuated, causing a translational movement of the wall portion delimiting or defining the cavity and the wall portion being shaped in terms the topology thereof in such a way that it is adapted to the shape of the at least one cavity with the at least one opening thereof.

Actuator assembly

A cooperative actuator system for active flow control, a vehicle comprising such cooperative actuator system, and a method for operating an actuator system for active flow control. The cooperative actuator system includes actuators, a control unit, and a data unit. The actuators are distributed along the surface in at least a first group and a second group downstream of the first group. The control unit is configured to control the actuators of the first group so that they form a first flow structure along the surface. The data unit is configured to provide data of the first flow structure. The control unit is further configured to control the actuators of the second group based on the data of the first flow structure, so that the actuators of the second group cooperatively interact with the first flow structure to form a second flow structure along the surface.

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.

A micromechanical rotation speed sensor with a gimbals-mounted structure capable of vibration includes two vibration elements () which are swivelled about two axes (A, B) oriented perpendicular toward each other. An excitation unit in the form of an electrode () sets the first vibration element () into a vibration about the first axis of rotation (A). A read out unit in the form of a read out electrode () records a tipping or vibration of the second vibration element () about the second axis of rotation (B) as a measure for the rotation speed of the sensor. Additional mass elements () which are symmetrically aligned are situated on the upper side () and the underside () of the first vibration element () which form a rocker. The sensor is manufactured of at least three individually processed wafers which are finally joined together and form a top part (), a midsection () and a bottom part ().

A self-testing sensor (especially to measure an angular rate or acceleration) includes a resonant structure, an actor unit configured to excite the structure to a first periodic vibration, a piezoresistive element configured to generate an output signal that depends on the measured quantity, and an isolator configured to isolate a test signal component from the output signal, whereby the test signal component is generated by a second periodic vibration of the structure superposed on the first vibration. A device for self-testing a sensor includes an isolator configured to isolate a test signal component superposed on a useful signal component from the periodic output signal of the sensor, and it includes a comparator configured to compare the test signal component with a predefined value or a test signal fed to the sensor. For the self-test, a second periodic vibration is superposed on a first vibration of the structure, and an output signal containing information on the measured quantity is determined. A test signal component contained in the output signal is monitored.

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.
