The ELA 07 is a series of Spanish autogyros, designed and produced by ELA Aviación of Córdoba, Andalusia. The aircraft are supplied complete and ready to fly.[1][2]

Design and development[edit]

The ELA 07 series features a single main rotor, a two-seats-in-tandem open cockpit with a windshield, tricycle landing gear with wheel pants and a four-cylinder, air-cooled, four-stroke, dual-ignition 100 hp (75 kW) Rotax 912S engine in pusher configuration. The turbocharged 115 hp (86 kW) Rotax 914 powerplant is optional.[1][2]

The aircraft fuselage is made from TIG welded, CNC laser-cut stainless steel tubing for corrosion resistance. The cockpit fairing is non-structural carbon fibre and resin. Its 8.23 m (27.0 ft) diameter rotor has a chord of 22 cm (8.7 in) and is mounted to a rotor head made from a combination of stainless steel and 7075 T6 aluminium. The triple tail is also made from carbon fibre and resin. Equipment fitted includes a pre-rotator, pneumatic pitch trim and mechanical roll trim. The Cougar version has an empty weight of 250 kg (550 lb) and a gross weight of 450 kg (990 lb), giving a useful load of 200 kg (440 lb). A forward baggage compartment with a volume of 60 litres (13 imp gal; 16 US gal) is optional.[1][2][3]

Operational history[edit]

By January 2013 two examples had been registered in the United Kingdom with the Civil Aviation Authority.[4]

Variants[edit]

The aircraft fits an 8 m (26.2 ft) spray boom and an enlarged windshield. The Agro can be quickly returned to two-seat configuration by removal of the spraying equipment.[1][2]
