The DAR 1 Peperuda (butterfly) was a 1920s Bulgarian two-seat touring or trainer biplane, designed by Hermann Winter and built by the DAR - Drjavna Aeroplane Robotilnitsa - State Aircraft Workshops.[1][2]
The aircraft was a conventional two-seat single-bay biplane with a fixed tail-skid landing gear, powered by a 60 hp (45 kW) Walter NZ radial engine.[1][2] Further development resulted in the DAR 1A, which was powered by a 85 hp Walter Vega engine, eight DAR 1As being produced.
After the maiden flight and successful flight tests the DAR 1 was put into production in 1926.[1] Production DAR 1A aircraft were delivered from 1928.[1]
The tewelve DAR 1 and eight DAR 1A aircraft were used by the Bulgarian Air Force at the Kazanlak Air School, for primary training and the Yato fighter squadron for continuation training, from 1926 to the early 1940s. Some DAR 1A aircraft were also used by the Civil Air Service as glider tugs.
