from Wikipedia

edited by Tim Wing

The Antonov An-72 (UEDF reporting name Coaler) was a Soviet transport aircraft, developed by Antonov. It was designed as a Short Take-Off and Landing (STOL) transport and intended as a replacement for the Antonov An-26. Variants also found success as commercial freighters.

The An-72 and An-74 get their nickname, Cheburashka, from the large engine intake ducts, which resembled the oversized ears of the popular Soviet animated character of the same name. Nickname Galya (Galina – the popular Ukrainian female name) is also known.

Design and development

An-72 3The An-72 first flew in December 1977. Produced in tandem with the An-72 was the An-74 variant, which added the ability to operate in the harsh Polar Regions. It could be fitted with wheel-skis landing gear, de-icing equipment and a number of other upgrades which allowed the aircraft to support operations in Arctic or Antarctic environments. Other An-72 versions included the An-72S VIP transport and An-72P maritime patrol aircraft.

An unusual design feature of the An-72 was the use of the Coandă effect to improve STOL performance. This worked by utilizing engine exhaust gases blown over the wing’s upper surface to boost lift. The An-72’s first flight was made on 31 August 1977, but it was only in the 1980s that production started. The power plant used was the Lotarev D-36 turbofan engine. The An-72 bore a strong resemblance to the American Boeing YC-14, a STOL prototype from the early 1970s.

The rear fuselage of the aircraft had a hinged loading ramp with a rear fairing that slid backwards and up to clear the opening. The An-72 could air drop up to 7.5 tons, and was equipped with folding side seats for 52 passengers.

The An-72 had STOL capabilities with a minimum takeoff roll of just 620 meters and a landing run as short as 420 meters. This aircraft was designed to be used on unprepared surfaces: its robust undercarriage and high-flotation tires allowed operations on sand, grass or other unpaved surfaces. This was a feature

Operational history

The An-72 first entered service with the Soviet Air Force in 1980. It served with the Soviet Air Force as a medium transport until the Invid Invasion. Among its many uses, the An-72 served most famously with the Soviet Air Force Frontal Aviation as a transport for air borne forces. With a payload capacity of nearly 20 metric tons, the Coaler was capable of transporting a single armored vehicle such as the BMP-3.

The An-72 also saw success on the civil aviation market. Over a hundred examples were sold all over the world, primarily to African carriers who needed an aircraft with good short, unimproved airfield performance. It was just this capability that put the An-72 into heavy demand in the post war period. It was this market demand that caused Antonov to put the Coaler back into production.
