Bücker Bü 133 Jungmeister


The Bücker Bü 133 Jungmeister 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

The Bü 133 was a development of the Bücker Bü 131 Jungmann two-seat basic trainer. First flown in 1935, it was slightly smaller than the Bü 131. The prototype, D-EVEO, was powered by a 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 version of that same Hirth HM506 inline-6 engine, were built.
The main production type was the Siemens-Bramo Sh 14A radial powered Bü 133C, which had a distinctive cowling and a -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. A similar number were built for the Spanish Air Force by CASA, and were designated the CASA 1-133.

Operational history

The Bü 133C racked up numerous victories in international aerobatic competition, and by 1938 was the Luftwaffes 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.
