Baumann Brigadier

The Baumann Brigadier was a light passenger aircraft produced in small quantities by the “Baumann Aircraft Corporation” during the 1950s. It was essentially based on the B-250 prototype, which first flew in June 1947.

The prototype featured a mid-wing cantilever design with structural elements made from light alloys. It had a semi-monocoque fuselage, a simple empennage, and retractable tricycle landing gear.

Original Design Features

The power plant consisted of two horizontally mounted Continental C125 engines, each delivering 125 hp, positioned on either side of the fuselage. These engines were housed in wing nacelles and drove two-bladed pusher propellers with prominent spinners.

While the B-250 possessed good handling characteristics, it was distinctly underpowered. Consequently, the production model, the B-290, launched in a limited series in 1952, utilized a more powerful engine setup. Yet, even with this improvement, its radical appearance, and relatively spacious cabin, the aircraft failed to attract customer interest.

Planned Variants and Legacy

Two further versions with more powerful engines were planned: the B-360 Brigadier (with a 180 hp Lycoming) and the B-480 Super Brigadier (with a 240 hp Continental O-470), but neither of these concepts was ever realized.

One B-250 Brigadier was eventually purchased by the Piper company and operated under the designation PA-21 Twin.
