Method and device for precisely positioning a vehicle in a wind tunnel

A method for the accurate positioning of a measurement object to be examined aerodynamically, in a measurement position in a wind tunnel, in which the object assumes an accurately predefined relative position in relation to the axis of the wind tunnel, the measurement object being supported in the measurement position in a stable position on a floor of the wind tunnel by auxiliary supports, comprising:

• outside the wind tunnel, placing the measurement object onto a measurement-object carrier that is adapted to be movable at least in a longitudinal direction of the wind tunnel, the measurement object thereby being aligned accurately with respect to the carrier, and
• moving the measurement-object carrier with the aligned measurement object into the wind tunnel, and stopping the measurement-object carrier in the wind tunnel in an accurately redefined position, transferring the measurement object subsequently to a measurement section of the wind tunnel only in the vertical direction and thereby or subsequently locking the measurement object, the measurement-object carrier being brought into a waiting position that neither influences nor interferes with the measurement, after the measurement, accepting the measurement object by the measurement-object carrier again or transferring the measurement object to the measurement-object carrier, and finally, taking out the measurement-object carrier with the measurement object of the wind tunnel.
