ON THE DESIGN OF SOME AIRFOILS FOR SAILPLANE APPLICATION
Keywords:Aerodynamics, Structures, Design
AbstractAt the Delft University of Technology Low Speed Laboratory (LSL), an investigation was conducted to design and test some new airfoils for the wing of a Standard Class sailplane. To avoid building a new wing, the airfoils were designed such that just by adding material to the surface an existing wing could be modified and tested in flight. For this purpose, the ASW-19B was selected mainly because of its relatively thin wing. The manufacturer, Alexander Schleicher Segelflugzeugbau, was willing to participate in this investigation and provided two wing test segments used for wind tunnel experiments, as well as a new sailplane which was flight tested before and after the wing modification. This paper describes the considerations, tests and results of this
