The Charlotte was a single-seat, tailless glider owned by the Berlin Academic Aviation Group .
history
Work on the group's first aircraft design began in 1921. Hermann Winter designed the wing and controls, Edmund Pfister fuselage and vertical stabilizer. The construction work was lengthy due to unresolved issues of longitudinal stability and flight control. To support the students, August von Parseval and his assistant Hans Seehase held additional teaching exercises at the TH Berlin . Wilhelm Hoff , as head of the DVL in Berlin-Adlershof, was available for questions.
Construction of the aircraft named after the university location began in the university's attic. Construction delays endangered the desired participation in the Rhön competition in 1922. Thanks to the connection between Seehase and Sablatnig Flugzeugbau , the Charlotte could be completed there.
construction
The Charlotte was a single-seater, braced wooden shoulder decker , covered with fabric, with a half-timbered hull. The wing in Zanonia shape consisted of a rectangular center section and retracted wing tips with attached control flaps. Two elastic runners under the fuselage formed the chassis.
The pilot used two levers on the left and right of the pilot to steer: Movement in the same direction led to elevator and opposite to aileron effects of the control surfaces, which were then deflected in opposite directions. Control around the vertical axis took place via a rudder operated by foot pedals.

Trivia
Despite the 2000 marks received by the jury, there was not enough money for the return transport of the aircraft damaged in the 1922 Rhön competition as rail freight. Ten weeks after his crash, Winter set off on foot with Pfister and others and the remains of Charlotte on foot back to Berlin. The sensation generated in this way led to an article in the national Berliner Vossische Zeitung , whereupon a donor was found for the freight costs by rail from Eisenach.
