Scheibe SF-27A Zugvogel V (migratory bird) is a single-seat Standard Class glider designed by Egon Scheibe and Rudolf Kaiser at Scheibe Flugzeugbau GmbH in Dachau, West Germany, in the 1960s. It is a shoulder-wing aircraft of mixed construction, with wooden wings covered with plywood and fabric, and a fuselage welded from steel tubes, covered with laminate in the front section (up to the trailing edge of the wings) and fabric in the rear. The landing gear is fixed, with a tail wheel.
The prototype made its maiden flight on 12 May 1964. One example of the SF-27B version with a 17 m wingspan was also built. An SF-27M version was also developed, equipped with a retractable two-stroke, four-cylinder Hirth F-102 A2 engine of 26 hp housed in the fuselage, enabling the pilot to reach an airfield in case of loss of thermals.
120 examples were produced in West Germany. These gliders were also manufactured under licence in France under the designations LCA-10 and LCA-11 “Topaze”.
The exhibited example, serial number 6054, registration D-1790, manufactured in 1966, was donated to the Museum’s collection by Piotr Goliasz in June 2024.
