windtunnel measurements on some airfoil sections at
Reynoldsnumbers between 60,000 and 500,000"

Information about "De Starthaak"
The Model Aviation Club "De Starthaak" is active on a very nice location in the region between Eindhoven and Heeze in the Netherlands. Radio controlled (thermal) soaring models are allowed to fly from this field. The picture below shows the the location photographed from a full scale
sailplane.

The field can be reached by taking exit Geldrop / Heeze on highway A67, direction Heeze. At the first roundabout, go to the right. 300 m after the railway crossing, go to the right (Kreyl) and and the first road to the left (Huisvenseweg). At the end of that road (after 3 km) you will find the field.
More information about the club and its activities can be obtained from the secretary and the chairman of De Starthaak and from the next link (in Dutch).
This is a preliminary report on wind tunnel measurements performed during my
study on some airfoils that were popular around 1977.
The final
report has never been finished, but the pictures in the report speak for
themselves for all people who are interested in airfoil characteristics.
