From 1992, Aerospatiale's helicopter division was integrated into Eurocopter. Eurocopter's Ecureuil (= Squirrel) is in extensive civil and military use worldwide undertaking a variety of wide ranging missions. Initial models offered were the Arriel powered AS-350B, which was marketed outside North America, and the LTS-101 powered AS-350C AStar sold in the USA. The AS-350C was soon replaced by the D, with a more powerful engine.
Subsequent developments include the hot and high AS-350B-1 with a 684shp( 510kW) Arriel 1D; the AS-350BA which was certificated in 1991 and was in production through to 1998 and is fitted with the larger main rotors of the AS-350B-2 (AS-350Bs can be retrofitted to BA standard); and the AS-350B-2 (marketed in North America as the SuperStar) with a more powerful Arriel 1D1 turboshaft, and the main and tail rotors developed for the twin engine AS-355F Ecureuil 2 and certificated in April 1989. The AS-350B-3 first flew on March 4 1997 and is a hot and high optimised model. Its most important change is a more powerful Arriel 2D engine. Deliveries began in January 1998.
Later production military Ecureuils are marketed as the AS-550 Fennec. |
