Overview 2
The Bücker Bü-133 Jungmeister (Young master) was an advanced trainer of the Luftwaffe in the 1930s. It was a single-engine, single-seat biplane of wood and tubular steel construction and covered in fabric.
Development 2
The Bü-133 was a development of the Bücker Bü-131 Jungmann 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) version of that same Hirth HM506 inline-6 engine, were built.
The main production type was the 160 hp (119 kW) Siemens-Bramo Sh 14A radial 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.
Operational History 2
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.
