|DP1,68-8,37_DS||08.37%||(27. Nov 2006) "The DP-DS-airfoils are made for extreme top speed DS-sessions (Re = 1.000.000 - 2.000.000. They start to run at a speed of 40 m/sec or more. They are thick so that it´s easier to build a rigid wing and dam fast. If you will use them for a normal F3B or F3F soarer you will be disappointed. The design has a much longer laminar flow than the DS-19 which is used by Brian McLean's Extreme. This should lead to a remarkable higher top DS-speed. The laminar bucket is for the most of the airfoils between Cl = 0.15 and 0.6 and therefore in the most used lift regions what concerns DS.
The airfoils can be used by every private person. A commercial use is restricted by the designers copyright. If a commercial use is desired or someone needs a different design for a different task please .
If you have build a soarer with one of these airfoils please contact me to tell me your flying impressions. If you are interested in a substantial support for a complete DS-soarer by my person or if you have any remarks to the airfoils please . "
(1 dec 2006) - I got several requests for airfoils which are suitet for smaller ds planes (2m or 80") and a Reynoldnumber of 500.000-1.000.000. You can use the thicker one at the wing root and the thinner one at the wing tip, or from the middle of the wing up to the tip.
