The Concordia is an open class glider that was initiated by Dick Butler and Gerhard Waibel and has been optimized for competitive use .

history

The development goal of the aircraft project, which emerged from the 2002 "eta-biter" project, also promoted by Dick Butler, was maximum performance for gliding competitions without regard to profitability, series production and suitability for pilots with little experience. In 2003, Loek Boermans from the Technical University of Delft could be won over to design the wing profile. Much of the work for this was carried out by one of his students, Johannes Dillinger, as part of a master's thesis until 2006. The production took place with the support of Hansjörg and Christian Streifeneder.

The Concordia was first used at the 2012 World Gliding Championships in Uvalde, Texas . Series production is not planned.

construction

The Concordia has an extremely narrow wing with a wingspan of 28 meters, which, with its exceptionally small area, can be flown with higher wing loads than competing aircraft with a similar wingspan. An ASW-27 fuselage is used in the cockpit area . The fuselage-surface transition was also derived from this aircraft type, but optimized for a quick preliminary flight. The tail boom is very slim and, due to the small wing area, can be a little shorter than on comparable aircraft. The calculated best glide ratio is over 70, at 210 km / h a glide ratio of around 50 should still be achieved. The shapes for the wings, like those of the Nimeta, come from Glasfaser-Flugzeug-Service GmbH Hansjörg Stripeeder .
