Transonic wind tunnels are similar in design to subsonic wind tunnels, but can achieve speeds close to the speed of sound (Mach 1). The highest speed is achieved in the test section. Because transonic ...

It was donated by General Motors. This tunnel will be set up as long as the lab space is available. It is particularly suitable for ground vehicle testing. This is a closed-circuit, closed test ...

The small wind tunnel with a 16-by-16 inch test section is a low speed, open return tunnel, as shown in Figure 1. It is mainly used for airfoil section tests and teaching. he velocity is up to 50 m/s.

although they are also used in other wind tunnels, e.g. for analysis and exposure to high Reynolds numbers. The Institute operates a pitch test rig (NVS) to demonstrate forced motion. It consists of a ...

Characterizing the aerodynamic performance of a vehicle usually requires a wind tunnel since ... and precision-graded section of road, anyway. Turns out the Catesby Tunnel in the UK meets those ...

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 ...

While recent simulations seemed to support Tesla’s claims, the best way to confirm Tesla's numbers is by testing a production Cybertruck in a wind tunnel. Independent test results are unlikely ...

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 ...

ABB has upgraded a variable speed drive to extend the life of NASA’s National Transonic Facility (NTF) wind tunnel by at ...

The test validated the missile's design and confirmed the wind tunnel test outcomes on its updated aerodynamics.

Typically, when we talk about wind tunnels, we think of the big facilities in use by the aerospace and motorsports industries. However, there’s nothing stopping you building a wind tunnel of ...

The air in a wind tunnel is squeezed around the test vehicle so there’s always blockage which distorts the air, he adds. ‘Catesby Tunnel has blockage too but has a large cross section (40m2) ...
