Blow Down Wind Tunnels are a special type of Open Circuit wind tunnel. For Blow Down Wind Tunnels, however, air is blown down into the wind tunnel by a fan located upstream of the test section, as the name implies. Compared to standard Open Circuit wind tunnel configuration, blow-down style tunnels provide an extra degree of testing flexibility. For most Open Circuit tunnels, fan assemblies are located downstream of the test section and air is drawn through the wind tunnel with suction. Most commonly, these tunnels are used for tests requiring liquid or particulate injection. All blow-down style tunnels have custom test sections, and many are requested to include built-in test article mounting arrangements. Because all tunnels are made to fit the customers needs, there is no limitation to the options available.

Unsymmetrical Cantilever Apparatus Angular adjustment can be made easily and the angular position can be read off using the integral angular scale and pointer. The free end of the cantilever has point loads applied using the load hanger and calibrated weights. Unsymmetrical Cantilever Apparatus allows the vertical and horizontal deflections of the free end of a test specimen to be measured when loading occurs along a principle axis or at a known angle. Unsymmetrical Cantilever Apparatus holds the indicators relative to the rigid end of the cantilever to ensure accurate deflection measurement. A solid base holds a rigid vertical end support for the clamping of the test cantilevers. Test cantilevers and rectangular cross section are supplied. The free end movement is measured using deflection indicators. Shear centre work can also be undertaken.

The single-use, User-programmable Temperature Data Logger (UTDL) with an USB interface for data download, analysis, and programming of device settings via a PC. The device shows any temperature alarms that have occurred via a multicolour LED indicator.
Device settings, such as alarm thresholds, logging interval etc., can be programmed by the user via the Plug and Play Configuration Tool software or factory programmed. The device is factory programmed with generic settings by default and if other factory-programmed settings by Honeywell are required, such settings need to be specified upon ordering.
When connected to a PC via the USB interface, the device automatically generates a PDF report showing the recorded temperature data and alarms without the need for additional software.
