Akaflieg München Mü31
The Akaflieg München Mü 31 is an under construction high-performance glider for the 15 -m FAI racing class the student Fliegergruppe Akaflieg Munich.
History
After the production of the mu 30 there was the end of the 1990s, considerations for a new project. Several student projects at the TU Munich busy at that time trying to reduce the flow resistance of the current gliding configurations. From these considerations, the Mü was 31 with its optimized wing-fuselage junction. Extensive wind tunnel tests at TU Delft demonstrated the advantages of the concept in 2005. The construction work for the prototype are completed and the manufacturing is done currently (as of 2012) in the workshops of Akaflieg Munich in Garching near Munich. With the load test of the wings, the students were able to master end of October 2011 an important step towards approval.
Construction
The entire aircraft is usually manufactured with fiber composites as in modern gliders. In order to reduce construction costs, some parts of the ESP 27 are used for the mu 31. Thus, the entire tail and parts of the fuselage are adopted. A major focus is on the wing-fuselage junction. The surfaces are very high attached to keep the intersection and thus the interference resistance as low as possible.
