SCHLIEREN APPARATUS FOR AF300

A monochrome Schlieren apparatus for use with the Intermittent Supersonic Wind Tunnel (AF300).

The Schlieren apparatus allows students to see density gradients as variations in intensity of illumination. This allows them to see supersonic air flow patterns around models. It also clearly shows shockwaves and expansions, and students can compare their positions and angles with values predicted by theory.
The mirrors and lenses are of high optic standards to reduce any possibility of optic distortions of the images.

The apparatus includes digital imaging equipment to record the images, this is useful when using an intermittent supersonic wind tunnel.

The video monitor is particularly useful to display the images to groups of students. The imaging equipment can capture still images and any real-time changes in the image.
