Measurement arrangement for the precise and rapid positioning of fluid flow measurement sensor relative to vehicle or vehicle component in wind tunnel

摘要

The flow sensor is positioned on the forward end of a traversing device and moved relative to the surface of the vehicle in a precise position. To ensure that the position is as desired a laser measurement device (16) is used that transmits a laser beam towards the surface of the vehicle and from the reflected beam determines the position of the sensor from the surface. The measured value is used to correct the probe position to its intended position.
