Design of the AS350 family of light single-engine helicopters was started in the early 1970s as a successor to the SA 316 Alouette and the SA 341 Gazelle. The design was one of the first to be executed by the newly formed helicopter division of French aircraft manufacturer, Aerospatiale. Aerospatiale was formed in the early 1970s by combining most of the French government-owned aerospace companies, including Sud Aviation, which had been responsible for helicopter design and production. In the 1990s, the helicopter division of Aerospatiale was merged with the German MBB helicopter company to form Eurocopter. Today, Eurocopter is a division of EADS, a multinational European aerospace giant.
The AS350 was a completely new design that introduced several major innovations to the helicopter world, including the use of composites for the cabin structure, the rotor head as well as the blades. The helicopter was originally designed to accept two different engines (a Lycoming LTS 101 for the North American Market and a Turbomeca Arriel 1B for the rest of the world). However, the AS350B2, was offered only with the Turbomeca engine as a result of customer preference. Cabin design incorporates a wide, unobstructed cabin as first used on the SA 316. The standard seating configuration has a pilot and one or two passengers up front and a four-place bench in the back. Alternatively, two litters can be placed longitudinally on the left side of the cabin, one on top the other. The helicopter is also approved for external lift work. The AS350 series has proven to be very popular with all segments of the commercial helicopter industry. In addition, many law enforcement and military organizations have found it to be a cost-effective machine.
The drivetrain for the AS350B2 uses a Turbomeca Arriel 1D1 engine and a three-bladed composite rotor head and blades. The AS350B2 differs from its predecessors, the AS350BA and the AS350B1, by using an engine with higher shaft horsepower, a transmission with a higher power rating and a higher maximum takeoff gross weight.
The AS350B2 was certificated in 1989 and production started in 1990. In addition, some older AS350B1 and AS350BA, have been converted to AS350B2 status.
Soloy Aviation Solutions takes the AS350B2 model and swaps the power plant with a Honeywell LTS101-700D-2 engine, producing 650 shp while retaining all the original drivetrain components. This improves fuel consumption for the same mission.
