The IPD Urubu (Brazilian-Portuguese name for the Vulture) also known as the IPD/PAR PE 80367, was a two-seat sailplane of high-wing.
Design and development
In July 1978, the Ministry of Aeronautics asked IPD to develop a biplace glider to replace the LET L-13 Blaník, which was reaching the end of its service life. The work was executed by PAR (Divisão de Aeronaves) of the IPD. Development was completed in a few months and the prototype ordered from Aerotec, having been completed in 1979.
Construction
Monocoque construction, entirely made of metal, the new glider was baptized "Urubu", and underwent a series of tests that proved its efficiency in flight, being approved by the Civil Aviation Department. Biplace, in tandem-seat, had a bubble canopy, and a fixed auxiliary wheel, built into the fuselage.
