The story
Founded by Carlo Leopoldo Lualdi in 1954.1
Aer Lualdi was founded in Rome in 1953 by Carlo Lualdi, who had purchased a license to produce a Hiller-designed rotor system (the Hiller "Rotor-Matic") and thereby became the Italian agent for Hiller Helicopters.
Carlo Lualdi had previously used this rotor system in his experimental Lualdi-Tassotti ES 53, which featured a rotor design based on Hiller with a controllable transverse secondary rotor and first flew at Campoformido in 1953. With his new company Lualdi now built a succession of more powerful helicopters incorporating the Rotor-Matic system with a gyro stabilizer of his own design.
The first helicopter following the ES 53 was the L.55, an all-metal prototype which was followed by the L.57 and culminated in the four-seat L.59 which was selected for production by Macchi. One full prototype was built, and the commercial type certificate issued in August 1961.
Air Lualdi never went into full production and closed down in 1964, after the L.59 was cancelled.
