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-engine monoplane was chosen, with a high-located, elongated trapezoidal wing 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 and engine nacelles were designed by the now defunct French aviation engineering company, Aerospatiale. The wing length of the aircraft is 24,57 meters. Such a wingspan, with a total aircraft length of 22,67 meters, allows it to remain as stable as possible at low flight speeds, for example, when landing. Under the wings of the first prototype, ATR-42, Pratt & Whitney Canada PW120 turboprop engines with a capacity of 1800 hp were used as a power plant. Bugatti ".

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

The aircraft was certified in September 1985. After that, the production of a serial machine began, which received the designation ATR 42-300. The PW120 2000 hp engines were used on this modification. and a four-blade propeller. This model has become the basic version of the ATR 42 family aircraft. It can carry 42 passengers over a distance of 1500 kilometers at an average speed of 450 kilometers per hour. This modification was produced until 1996, after which it was discontinued, but is still in operation. The ATR 42-300 version was improved by two modifications. The first modification is the ATR 42-320, which received 121 hp Pratt & Whitney Canada PW2100 engines. The second modified version, designated ATR 42-400, had the engines that were previously installed on the ATR 42-320, but with a six-blade propeller.

The ATR 42-500 is powered by PW127E 2400 hp turboprop engines. and new six-blade propellers made of composite materials. Also in the new version, it was possible to increase the carrying 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 has the new PW127M engines, which are 5 percent more efficient than the PW127E engines. Also the new ATR 42-600 has lower operating costs and higher fuel efficiency. New, comfortable and lighter passenger seats are being installed in the aircraft cabin. The aircraft's flight performance has also become much higher. The cruising speed of the new car is 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 for displaying all flight information, and a multi-purpose computer MPC (Multi-Purpose Computer). This contributes to ease of control, and hence to further enhance flight safety.
