Western Michigan University's applied aerodynamics laboratory took over the advanced design wind tunnel from the former McDonnell Douglas ... Low turbulence and good flow direction control are ...

Buried some 30ft below the surface and absolutely straight, the tunnel offers consistent temperature and humidity while its new surface was laid in one continuous flow ... out in a wind tunnel ...

The basic research wind tunnel at Western Michigan ... growth of the wall boundary layers. The tunnel in its present configuration has a contraction ratio of 10.67. Immediately upstream of the ...

The H2K of the DLR Institute of Aerodynamics and Flow Technology in Cologne is a wind tunnel with a free-jet test section. The facility enables aerodynamic and aerothermal characterisation for scale ...

The fans in these wind tunnels are often powerful enough to achieve the required wind speeds without the need for complex components to manage the air flow. High-speed wind tunnels are used to test ...

Subsonic wind tunnels can achieve speeds up to 400 km/h and have an open return or return flow structure. Air is moved by a large, axial fan that overcomes viscous losses by increases in dynamic ...

The transonic cascade wind tunnel (TGK) is installed at the Institute ... Among other things, this is made possible by the continuous closed-loop operation of the tunnel. In addition, the aerodynamic ...

The transparent walls for observation are created out of acrylic, while a simple fan provides the necessary flow. The desk-sized wind tunnel can then be instrumented with a manometer, tachometer ...

Postdoctoral researcher Girguis O. Sedky  sitting inside of the wind tunnel, showing the covert feather-inspired flaps attached to the 3D-printed model airplane wing. The flaps deploy automatically in ...

Meanwhile, Earth's potent magnetic field (generated by Earth's metallic core) deflects many particles from solar storms and ...
