| 摘要 |
The invention relates to a test arrangement (10) having a test model (20), to which a flow (S) can be applied for flow-dynamic analysis and which has at least one control element (22, 23, 24, 25, 26) which essentially influences the flow behaviour of the test model (20). A flow setting device (60), which is arranged upstream of the test model (20) and is intended to influence the flow (S), and a sensor system (80) for detecting the flow (S) which is applied to the test model (20) are also provided, wherein the control element (22, 23, 24, 25, 26) can be adjusted on the basis of at least one value which is determined by the sensor system (80) and/or on the basis of the setting of the flow setting device (60). The invention also relates to such a method and to an actuator for use in such an arrangement or such a method. |
