The Akaflieg Berlin B13 is a two-seat motor-glider designed and built in Germany.

[1] Students at Akaflieg Berlin studied a high-performance motor-glider with the engine in the nose and an automatically folding propeller.

After approval was given, a prototype was built in 1991, as the ' Akaflieg Berlin B13', using GFRP (glass-fibre re-inforced plastic) to form a fuselage with smooth lines, housing the engine in the nose and a two-seat side-by-side cockpit covered by a large plexiglas canopy.

[1] Intended to use a sustainer motor, for sustaining flight only, power was to be supplied by a modified 24.5KW (33 hp) engine in the extreme nose driving a 5-blade folding retractable propeller, specially developed by Prof. Oehler.
