Akaflieg München Mü31
The Akaflieg München Mü31 is a high-performance single-seat glider aircraft that is under design in Germany as of 2010. Development. After completion of the Akaflieg München Mü30 Schlacro, students turned to the design of a new 15m-FAI racing class glider, with a maximum span of 15m (49 ft 3in), a maximum of 150 liters (40 US gallons) of water ballast and full-span flaps. Designated Akaflieg München Mü31, this glider is being designed to minimize interference drag between fuselage and wing root, with several variations being studied to select the ideal configuration : These concepts were wind-tunnel-tested in 2006. The third configuration was deemed to be best. The resulting fuselage wing joint is similar to a pylon with the wing suspended by the leading edge, leaving uninterrupted flow at the trailing edge. This layout has the advantages of: To keep construction costs low, the Mü31 will be built using components from the Schleicher ASW 27, such as the forward fuselage, rear fuselage and tail and outer wings.
