Abstract: A wind tunnel with an open jet measurement section for simulating wind direction changes, preferably for testing vehicles, is provided with a nozzle that can be swivelled during operation of the wind tunnel in order to change the wind direction. The front part of the nozzle is surrounded by a cylindrical surface sealed with respect to the measurement chamber in the front face of the nozzle pre-chamber, in the manner of a plug.
