The Cicaré CH-3 Colibrí was a helicopter made by the Argentine manufacturer Cicaré Helicópteros .
history
In 1973 Augusto Cicaré began developing his third helicopter, the CH-3 Colibrí . The prototype was completed in 1974. Due to a request from Fuerza Aérea Argentina in the meantime for a helicopter for training and agricultural tasks, it was rebuilt between 1975 and 1976 - before it even flew - from which the variant CK1 emerged. Ultimately, the first flight took place in early 1976. Although the Air Force was satisfied with the performance and ordered 5 pre-series copies, this order was canceled again for unknown reasons.
construction
The CH-3 was a 2- or 3-seater helicopter with seats arranged next to each other and a closed cabin. The fuselage consisted of a tubular steel construction, which was clad with aluminum sheets. The four-blade main rotor, like the tail rotor, was driven by a Lycoming HO-360-D1A four-cylinder boxer engine with 149 kW.
