AgustaWestland AW139 is a two-engine transport helicopter of the same class to the Bell412 and Sikorsky S-70. It embodied many new technical solutions, and it is sold actively for export.
The development of AW139 started with the project of the company AgustaBell AB139. The prototype of this car took off for the first time on 02/03/2001 at the aerodrome of the Agusta plant in Vergiate. The first helicopter took off on June 24, 2002, and deliveries began in 2003.
The designation was changed to AW139 when Bell sold its stake to Westland and left the project. In 2007, a second plant was opened in Philadelphia to serve the American market. The helicopter is currently used in approximately 30 countries.
In 2004-2006, AW139 participated in the competition, which was announced by the US Army for a light general-purpose helicopter (to replace 300 obsolete OH-58 and UH-1). “AgustaWestland” presented the L3Communications model, but lost to the UH72ALakota, created based on the EurocopterES635.
The AW139 helicopter has fewer components and parts than in earlier machines of the same company. Its advantages also lie in the availability of systems and the use of integrated avionics, which makes maintenance easier. A modern five-blade main rotor and retractable landing gear provide a quick and smooth flight.
Two engines Pratt & Whitney (Canada) RT6S67S, power 1531l.s. (1142kW) give the helicopter impressive properties with the highest take-off weight of 6400kg. AW139 has a higher power ratio than any other twin-engine medium helicopter of this class, and has a great cruising speed under various load cases, even in rather difficult weather conditions. As an option, complete protection against the consequences of icing is provided. The helicopter fully meets the most stringent international standards. This made it possible to attribute it to category “A” (the ability to fly with full weight on one engine) without limitation in a wide range of operating conditions, including a hot and high-altitude climate. This useful quality opened the way for the helicopter to the markets of the Far and Middle East.
For the high level of customer support from AgustaWestland, the Danish aviation company VAOY has named the first and only AW139 the “Agusta Spirit.” The AW139 has reached a safety record that plays for consumers who need to fly over the sea, an important role, for example, supply transport traffic between oil rigs and the shore.
Among modern technologies, we call the integrated avionics system HoneywellPrimusEpic, AFCS (digital ACSULA on four axes), FADEC (digital motor control system), and 4 color LCD monitors with an active matrix, size 152.4×203.2mm.
A spacious cabin with two large doors can accommodate up to 15 people. There is a spacious luggage compartment with access from the outside and the cab.
