Aero HC-2 Heli Baby
The Aero HC-2 Heli Baby is a two-seat light general-purpose utility helicopter, designed by engineer Jaroslav Slechta, and produced by the Czechoslovakian company Aero Vodochody in the 1950s. It has a three-bladed main rotor, and a two-bladed tail rotor. The helicopter has an entirely metal frame and cockpit, and windows made of Plexiglas. It was the first Czechoslovakian-designed helicopter to be produced.
==Design and development==
The helicopter was designed by an engineer named Jaroslav Slechta. Construction of the prototype began in 1951, and testing commenced in 1954. The first flight occurred on December 3, 1954, and the public was introduced to the helicopter in 1955 at the Brno Industries Fair. Production was slated to begin in 1957, however, engine problems delayed it. The initial batch produced 200 of these helicopters. The Czechoslovakian Air Force was a user of the HC-2, as was the Czechoslovak People's Army. The Heli Baby is capable of carrying a pilot and 220 pounds of cargo 62 miles in one hour, while using 4.85 gallons of fuel. In 1959, it was one of the world's lightest two-seated helicopters. Initially powered by an Praga DH engine, the more powerful Avia M 110H engine, designed specifically for use in helicopters, replaced it after approximately six years. The Heli Baby can be used for transport, training, and various "other duties in military and civil service". In addition to its two seats, the helicopter has space behind it to carry cargo, and it had a tricycle undercarriage. Three wheels were used to support the helicopter on the ground.
