The (originally Aerospatiale) AS-365N Dauphin 2 is a much improved development of the original SA-365C Dauphin 2. Until January 1990 the AS-365 models were designated SA-365, and in 1992 Aerospatiale's helicopter division was incorporated into Eurocopter. The AS-356N introduced more powerful Arriel 1C turboshafts, enlarged tail surfaces, revised transmission, main rotor, rotor mast fairing and engine cowling, and retractable tricycle undercarriage.
Deliveries of the improved AS-365N-2 commenced in 1990. It features upgraded Arriel 1C2 engines, improved gearbox, increased max takeoff weight, redesigned cabin doors, revised interior and optional EFIS instrumentation. The AS-365N-3 is a hot and high development with FADEC equipped Arriel 2Cs. Deliveries began in December 1998.
The improved EC-155 (initially AS-365N-4) development was announced at the 1997 Paris Airshow. It features twin Arriel 2Cs equipped with FADEC, a five blade Spheriflex main rotor and a 40% larger main cabin, achieved with bulged doors. First flight was on June 17 1997, with French and German certification awarded in December 1998. |
