context_page_description: Akaflieg Karlsruhe is one of ten flying groups attached to German universities. Akaflieg is an abbreviation for Akademische Fliegergruppe, an academic group of students working with a German University. The Akademische Fliegergruppe Karlsruhe e.V. - is a group of students enrolled at Karlsruhe Institute of Technology, who are involved with the development and the design of gliders, as well as research in aerodynamics.
context_section_description: Aircraft designed and/or built at Akaflieg Karlsruhe include:
  Akaflieg Karlsruhe AK-1 "Mischl" self-launching sailplane
  Single seat glider: steel tube frame construction with fiberglass hull, 15 m of wingspan fitted with a retractable 4 cylinder, two stroke, 28 HP motor, type F10A from Hirth industries.
  Akaflieg Karlsruhe AK-2
  An adaptation of a Glasflügel 604 glider with a motor remaining in the hull, which was a novelty in the Seventies.  The project was cancelled in favor of AK-5 after 16 years.
  AFK-3
  A single engine Winch was conceived as a novelty, using one engine for driving the truck on the road and hauling the gliders into the air. The winch is hydro-electric and the winch operator uses the passenger seat instead of a separate operator cabin.
  Akaflieg Karlsruhe AK-5 "Ardea"
  Single-seat standard glider in Fiberglass construction. The hull is a Glasflügel 604. The wings have the shape of a Falcon, a prototype designed by Hansjörg Streifeneder (maiden flight 1981). The aim of the project was to pass on the knowledge and incorporate modern, less expensive construction methods as fiberglass. It can be used in instruction because of easy handling. The first flight was June 1, 1990.
  Akaflieg Karlsruhe AK-5b "Otto K.K."
  This is a development of AK-5 with "winglets" and rebuild hull interior. New, easier steering mechanics allow student pilots to fly and new materials are lighter. The first flight of AK-5b was 1996.
  Akaflieg Karlsruhe AK-8
  Single seat 15m standard class glider. New elliptical shaped were built with an aluminum mold. The hull is a DG-600M. Maiden flight of AK-8 was in 2003. After a crash a new left wing was finished in 2009. Improved wings with winglets and improved performance were added in 2014.
  Akaflieg Karlsruhe AK-9 or DG-1000J D-KAKJ "Jet"
  A 400N turbine was installed in a two seater DG-1000. In Cooperation with the Institute for Thermal Flowengines at the KIT the behavior of an AMT Titan Jet Engine by the Dutch producer Draline were researched and improved with a silencer.
  AK-X
  A pure wing glider-prototype with improved handling and performance is currently being built, inspired by the pure-wing conception of the Horten brothers and based on the experience of the SB-13 built by Akaflieg Braunschweig. A 1:2 model flew mid 2015.
