The Baumann Brigadier was a prototype American light transport aircraft of the late 1940s. It was a twin-engined monoplane, which, unusually, was of pusher configuration. Only two were built, plans for production never coming to fruition.
Development and design
[edit]Jack Baumann, who had worked for the Taylor Aircraft Company (later to become Piper Aircraft) and Lockheed,[1][2] set up the Baumann Aircraft Corporation in Pacoima, Los Angeles, California in 1945.[3] His first design for the new company was the B-250 Brigadier, a twin-engined pusher monoplane intended as an executive transport. It was of all-metal construction, with cantilever shoulder mounted wings, and with the pusher engines mounted in nacelles on the wing. An enclosed cabin accommodated a pilot and four passengers, while the aircraft was fitted with a retractable nosewheel undercarriage.[3]
The first prototype, powered by two 125 hp (93 kW) engines (hence the B-250 designation) flew on 20 June 1947.[4] Piper Aircraft was interested in building a tractor version of the Brigadier, and purchased the B-250 prototype and its drawings, designating it the PA-21,[4][5] with some sources [4] claiming that the B-250 formed the basis of the Piper Apache, although other sources state that Piper abandoned work on the PA-21 and that the Apache was unrelated.[5]
Baumann continued development of the pusher Brigadier, with the second example, the B-290, being fitted with 145 hp (108 kW) Continental C-145 engines but was otherwise similar to the B-250. The B-290, registered N90616, crash-landed at Pacoima on January 8, 1953, heavily damaging the fuselage and injuring pilot Ward C. Vettel and flight engineer Thomas Cox.[6] Production at a rate of one aircraft per month was planned for the B-290.[3] The Brigadier was chosen by Willard Ray Custer as the basis of his Custer CCW-5, which used the fuselage and tail of the Brigadier, but had a modified wing with the engines sitting in U-shaped ducts,[7] but other than the two CCW-5s no production of the B-290 followed. Baumann continued to propose more powerful versions of the Brigadier, but no airframes resulted.[4]
