Aeris Naviter AN-2 Enara

The Aeris Naviter AN-2 Enara (Basque for 'Swallow') is a Spanish helicopter that was under development by Aeris Naviter of San Sebastián. The AN-2 was first shown at the 2009 Paris Air Show at Paris–Le Bourget Airport. The aircraft was intended to be supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft.[1][2]

Introduction 2009
Status Development ended (2012)

The AN-2 was intended to have certification completed in the European Aviation Safety Agency Very Light Rotorcraft category by May 2010, and then again by the end of 2012 but, by January 2013, this does not seem to have been completed. Kits were intended to be ready for delivery in February 2010, but were not yet available as of January 2013. By late in 2011 there was no indication that the prototype had been flown.[3][4]

By 2012 the company website was redirected to Cicare Europe and all mention of the AN-2 had been removed. It is likely development had ended by that point.[5]

Design and development

The AN-2 Enara features a two-rotor coaxial main rotor, a two-seats-in tandem enclosed cockpit, tricycle landing gear with suspension, an H-tail and a four-cylinder, four-stroke, 115 hp (86 kW) BMW automotive engine. Plans for other powerplants include the four cylinder, air-cooled, four-stroke, dual-ignition 115 hp (86 kW) Lycoming IO-233 light-sport aircraft engine.[1]

The aircraft fuselage is made from aluminium sheet. Its 6.99 m (22.9 ft) diameter two-bladed rotors both have chords of 18 cm (7.1 in). The aircraft has an empty weight of 390 kg (860 lb) and a gross weight of 600 kg (1,323 lb), giving a useful load of 210 kg (463 lb).[1]
