The Bücker Bü 133 Jungmeister was a single-seat development of the Bücker Bü 131 - a double-decker from Bücker Flugzeugbau .
It was a bit smaller, single-seater and more powerfully motorized, but otherwise largely identical. The first flight took place on August 21, 1935 by works pilot Luise Hoffmann . The machine was used by various air forces, especially for aerobatics and air combat training. Because of its maneuverability and clean demolition behavior, it was also popular as a competitive aerobatic aircraft for a long time. Here is especially Albert Falderbaum to mention the Bü 133 was a master.
It was available with a Hirth HM-6 in-line engine of 101 kW (135 hp) as the Bü 133 A , as the Bü 133 B with a Hirth HM 506 in-line engine with 119 kW (160 hp) or from 1937 as the Bü 133 C (see data), in which the body was shortened.
A total of around 280 Bü 133s were built, 52 of them under license from Dornier (in Altenrhein in Switzerland), of which a few are still registered in Germany today.
production
The production of the Bü 133 in the German Reich cannot be precisely determined. The Bücker annual report reports that 99 aircraft (1 A, 89 C, 9 D) had been manufactured by the end of 1938. Up to March 31, 1941, 145 aircraft had been commissioned or were expected to be commissioned. 88 of the aircraft produced had been sold: 48 to the RLM, two to private individuals in Germany and 38 for export. The RLM order amounted to 68 Bü 133, which could be delivered by the beginning of the war. With a total of 68 RLM deliveries, two private sales and 60 exports, Bücker's production amounted to around 130 Bü 133s. The Luftwaffe had 68 aircraft on March 1, 1940. Since several aircraft were written off after accidents, it can be assumed that some unsold aircraft were taken over by the Luftwaffe for export at the beginning of the war. In June and July 1941 another ten Bü 133s were delivered to the Luftwaffe. The production in the German Reich probably did not exceed 160 Bü 133.
Switzerland flew a total of 52 Bü 133s, three of which were imports, i.e. 49 licensed buildings from Dornier, Altenrhein. CASA in Spain built 25 Bü 133 under license. A total of four Bü 133s were built as post-war buildings at Bitz in Augsburg between 1967 and 1969. Thus, the total production of the Bü 133s was less than 240 copies.
