ATR 42, a family of short-haul aircraft, the production of «Avions de Transport Regional» combined Franco-Italian aviation group.
Turboprop, twin-engine ATR 42, is the regional aircraft designed primarily for passenger transport on short in routing. Final assembly of the aircraft ATR 42, like the Airbus, made in Toulouse.
The program for the development of ATR 42, was officially opened in October 1981 years.
As aircraft design concept of the twin-engine monoplane was selected with vysokoraspolozhennym, elongated wing trapezoidal shape and "T" -shaped tail. The first prototype aircraft was designated as ATR-42-200, This version was built for testing purposes and is not produced in series. Wing aircraft and nacelles for the engines were designed by the now abolished French, aviainzhenernoy company, «Aerospatiale». aircraft wing length is equal to 24,57 meters. Such wingspan, with the overall length of the aircraft in 22,67 meters, allowing him to remain as stable as possible in small flight speeds, for example during the approach. Under the wings of the first prototype, ATR-42, as the power plant, were used turboprop engines Pratt & Whitney Canada PW120, with a capacity of 1800 hp .. The aircraft was used tricycle, retractable landing gear, which was responsible for the development of French company «Messier Hispano Bugatti».
The first flight of the ATR prototype 42, 16 held August 1984 years.
The certification of the aircraft took place in September 1985 years. Then began production of the serial machine, which received the designation ATR 42-300. In this modification, the engines were used PW120 power 2000 hp and four-bladed propeller. This model has become the base version of the ATR family of aircraft 42. It allows you to carry a passenger on the distance 42 1500 kilometers at an average speed 450 kilometers per hour. This modification was produced until 1996 years, after which it was taken out of production, but is still in operation. Improved version of the ATR 42-300, were two of its modifications. The first modification - ATR 42-320, which received engines Pratt & Whitney Canada PW121 power 2100 hp The second modified version, designated the ATR 42-400, had engines that were previously installed on the ATR 42-320, but with a six-bladed propeller.
In October 1995 year the airline began deliveries of the new aircraft ATR 42-500.
This new version of the family of ATR 42, has a more modern and ergonomic interior design with improved sound insulation as compared to the previous version. On ATR 42-500 installed capacity of turboprop engines PW127E 2400 hp and new lopostnye six screws, made of composite materials. Also in the new version, it was possible to increase the load capacity.
2 2007 October, the General Directorate of the company «ATR», announced the launch of the new version of the short-haul turboprop aircraft, the designation ATR 42-600.
In this version installed new engines PW127M, which in 5 percent more efficient engines PW127E. Also, the new ATR 42-600, has lower maintenance costs and better fuel efficiency. In the cabin installed a new, comfortable and lighter passenger seats Aircraft Flight indicators were also much higher. The cruising speed of the new machine is 556 kilometers per hour. He is able to carry up to 52 passengers on an average distance of 1555 kilometers. ATR 42-600, equipped with the latest avionics and navigation equipment includes five multifunction LCD monitors to display all the flight information, and a multi-purpose computer MPC (Multi-Purpose Computer). This facilitates ease of management, and thus to further improve safety.
The main operators large aircraft ATR 42 for today are: Brazilian regional airline «TRIP Linhas Aereas», the US postal and courier transport airline «FedEx Corporation», leasing the French «Airlinair» airline, as well as a group of Russian and foreign airlines "UTair.
To date, it produced about 425 aircraft ATR 42.
