Lualdi-Tassotti ES 53
The Lualdi-Tassotti ES 53 was an Italian experimental helicopter designed by Carlo Lualdi around a Hiller-designed rotor system and a gyro stabiliser of his own design. It first flew at Campoformido in September 1953. The helicopter was powered by a single 63.4 kW (85 hp) Continental C85 engine and proved so promising that Lualdi purchased a licence to produce the Hiller rotor system in Italy, and formed a new company, Aer Lualdi to develop and market his designs as the Aer Lualdi L.55 The Aer Lualdi L.55 was a prototype Italian helicopter, a development of the Lualdi-Tassotti ES 53 featuring a far more powerful Lycoming O-360 The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-co ....

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...
