The Antonov An-74 is a STOL - transport aircraft for short and medium-haul flights from Soviet and Ukrainian production. Originally, this variant of the An-72 was further developed for civilian supply missions in the Arctic . The two turbofan engines are arranged in front of or above the wings and guide the air flow over the wings in order to increase the lift ( Coandă effect ).

description

The prototype first flew at the end of 1983. Series production in Kharkov started in 1985. Due to its STOL properties, the An-74 manages with a 300-meter landing runway and a 250-meter take-off runway, as demonstrated in 1987 when it landed on the drifting ice floe of the polar station SP-27.

The arrangement of their engines led to the nickname " Cheburashka ", a film and novel character with big ears.

For use in the Arctic, skis can be mounted on the chassis. The wing leading edges can be de-iced. This allows use in zones from −60 ° to + 45 °. This allows it to operate from unpaved runways or from ice and snow surfaces in the Arctic, where other aircraft can no longer take off and land. In addition, improved navigation instruments and additional tanks were installed.

variants

The latest versions are the An-74T (freighter) and An-74TK-200 ( combined freighter ). Only two crew members are required here, and a higher take-off weight (larger payload) is possible.

The An-74TK-300 has conventionally suspended engines under the wings. The first flight was on April 20, 2001.

A new type of aircraft was developed based on the An-74-300 . This was equipped with improved engines and bears the designation Antonov An-148 .
