Bücker Bü133 Jungmeister

The Bücker Bü 133 Jungmeister (pronounced “Young master”) was an advanced trainer of the Luftwaffe back in the 1930s. This aircraft was a single-engine, single-seat biplane built of wood and tubular steel and it was covered in fabric. This single-seat advanced trainer, was manufactured by Bücker and built by Casa Dornier aircraft company.

The Bü 133 was a development of the Bücker Bü 131 Jungmann (“youngmann”) two-seat basic trainer. First flown in 1935 (by Luise Hoffmann, the first female works pilot in Germany), it was slightly smaller than the Bü 131. The prototype, D-EVEO, was powered by a 140 hp (104 kW) Hirth HM506 inverted, air-cooled inline-6 engine.

The aircraft showed “astonishing agility” at its first public appearance, the 1936 International Aerobatic Championship at Rangsdorf, but the Bü 133A garnered no orders; only two Bü 133Bs, with 160 hp (119 kW) Siemens-Bramo Sh 14A radials, were built.

The main production type was the Sh 14A-powered Bü 133C, which had a distinctive cowling and a 13 cm (5.1 in)-shorter fuselage, and the same fine aerobatic performance as the Bü 133A.

Fifty-two were manufactured under licence by Dornier for the Swiss Air Force (which kept it in service until 1968),. A similar number were built for the Spanish air force by CASA, and were designated the CASA 1-133.

The Operational history is as follows: CASA-built 1-133C Jungmeister at Blackpool (Squires Gate) Airport in 1957

The Bü 133C racked up numerous victories in international aerobatic competition, and by 1938 was the Luftwaffe’s standard advanced trainer. At the Brussels meet that year, a three-man Luftwaffe team made a strong impression on Reichsmarschall Hermann Göring, who ordered a nine-man team be formed. It dazzled the crowds at the International Flying meet in Brussels the next year.

The Jungmeister design remained competitive in international aerobatic competition into the 1960s.
