Development

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),[1] 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.[1]

The aircraft showed "astonishing agility" at its first public appearance, the 1936 International Aerobatic Championship at Rangsdorf,[1] 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.[1]

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,[1] and the same fine aerobatic performance as the Bü 133A.[1]

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

Operational history
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.[1] 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.[1] It dazzled the crowds at the International Flying meet in Brussels the next year.[1]

The Jungmeister design remained competitive in international aerobatic competition into the 1960s.[1]
