AK-X

Since October 2010, we have been working on the AK-X project, the development of a new type of flying wing glider. Conventional concepts have been extensively researched and iteratively improved by manufacturers and Akafliegs in recent years. The Akaflieg Karlsruhe is pursuing an unconventional idea with great potential by designing and developing a flying wing glider.

On Wednesday, 30.09.2026 it was finally time. The towing process and rolling behavior was tested, processes were discussed, flight order was filled. At 8:34 a.m., the towing machine, the fs35 of the Akaflieg Stuttgart, tightens the rope. A few moments later, the AK-X takes off for the first time in its history. It is flown by Ingmar Mayerbuch, Head of Flight Operations & Research Flight Department at the German Aerospace Center. Actually, the launch looks like any other, it wouldn’t be the world’s only modern tailless glider that rises here. The aircraft tow goes up to 8000 ft MSL, whereupon Ingmar begins the first tests: trim speeds, rudder authority, bulge flaps, brake flaps,… A little later, the AK-X is in approach to the slope 08 and the first flight is rounded off with a buttery-soft landing.
