Parks College Wind Tunnel Center Results

This page displays six pictures of the actual cross parachute wind tunnel test at the Parks College Wind Tunnel Center. Comparisons of actual and simulated geometries as well as of average drag results are also available.

This first picture is simply a view of the Parks Wind Tunnel setup. More information on the dimensions of the wind tunnel and of the cross parachute model is available.

Next we have a fairly good view of the final geometry of the cross parachute as given by the wind tunnel test. Also see a comparison of the actual and simulated geometries.

Shown at right is a view of a reefed cross parachute; the base of the chute is tied to force it to be much narrower than normal, as can be seen by comparing this picture to the previous one.

Here, an apex line has been attached to the middle of the cross parachute, and is being pulled to force a different geometry. Among other things, the stability of the new geometry was tested.

The reefed cross parachute at right has also been forced to take a different geometry, using an apex line as in the previous picture.

Finally, the cross parachute here has had its skirt folded (the sides of the cross parachute are half as long as before.)
