    Patent number: 4513610
    Abstract: Method and device for attaining a gas flow in a wind tunnel whereby a flow medium, preferably air, is caused to flow from a pressure storage (4) via a turbine (8) to a wind tunnel (9). The turbine (8) is arranged to drive a fan (18) positioned in the wind tunnel (9), and a partial flow of the medium flowing in the wind tunnel (9) is deflected from the wind tunnel circuit, whereas the main part is recycled and mixed with the flow being successively fed from the turbine (8).
