ATR 42 (APR 42)

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 the concept of the aircraft, the design of a twin-engined monoplane was chosen, with a high-placed, elongated wing of a trapezoidal shape and a “T” -shaped tail. The first prototype of the aircraft received the designation ATR-42-200. This modification was built for testing purposes and was not mass-produced. The wing of the aircraft and the nacelles for the engines were designed by the now-abolished French aircraft engineering company, Aerospatiale. The length of the wing of the aircraft is equal to the 24,57 meter. Such a wingspan, with the total length of the aircraft in 22,67 meters, allows it to remain as stable as possible at low flight speeds, for example, when approaching. Under the wings of the first prototype, ATR-42, as the power plant, were used Pratt & Whitney Canada PW120 turboprop engines, power 1800 hp. Bugatti.

The first flight of the ATR prototype 42, 16 held August 1984 years.

The aircraft was certified in September 1985. After that, the release of the serial machine, which received the designation ATR 42-300, began. On this modification were used engines PW120 2000 horsepower. and four-blade propeller. This model has become the basic version of the aircraft ATR 42 family. It allows you to carry an 42 passenger over a distance of 1500 kilometers at an average speed of 450 kilometers per hour. This modification was produced before 1996 year, after which it was discontinued, but is still in operation. Improving the version of ATR 42-300, have two modifications. The first modification is the ATR 42-320, which received the Pratt & Whitney Canada PW121 engines with the HP 2100 power. The second modified version, designated as ATR 42-400, had engines that were previously installed on the ATR 42-320, but with a six-blade propeller.

In October 1995 year the airline began deliveries of the new aircraft ATR 42-500.

This new version of the ATR 42 family, has a more modern and ergonomic interior design with improved sound insulation compared to the previous version. The ATR 42-500 is equipped with PW127E turboprop engines with HP 2400 power. and new six-blade 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.

This version is equipped with new PW127M engines, which are 5 percent more efficient than PW127E engines. Also, the new ATR 42-600 has lower operating costs and higher fuel efficiency. New, comfortable and lighter passenger seats are installed in the cabin. Flight performance of the aircraft has also become much higher. The cruising speed of the new car is equal to 556 kilometers per hour. It is capable of carrying up to 52 passengers over an average distance of 1555 kilometers. ATR 42-600, equipped with the latest avionics and navigation equipment, including five multifunctional LCD monitors, to display all flight information, and a multi-purpose computer MPC (Multi-Purpose Computer). This contributes to the ease of management, and hence further improve flight safety.
