BF-1 Beija-Flor
The Aircraft Department (PAR) of the Brazilian Research Institute (I.P.D.) built three prototypes of a small, two-seat light helicopter, originally designed by Professor Henrich Focke. The first prototype, designated I.P.D. BF-1 Beija-Flor, took flight on January 1, 1959, but did not enter series production.
Brazil’s Pioneer Helicopter
The BF-1 became the first helicopter designed, built, and flown in Brazil. The helicopter was constructed and tested under the aegis of the Center for Aeronautical Technology (CTA); in some sources, it is referred to as the CTA Beija-Flor.
Innovative Design and Market Challenges
The unusual feature of the BF-1 helicopter was its power plant: a Continental E225 piston engine delivering 225 hp (168 kW) with six horizontally opposed cylinders. The engine was situated in the extensive nose section, driving a three-bladed main rotor through a shaft system that proved too heavy. Flight performance suffered as a result, and the helicopter could not find its niche in a market already dominated by “Bell” and “Hiller” companies.
