Antonov An-72
Designed as a strategic military freighter, the Antonov An-72
(NATO reporting name: "Coaler") was intended as a replacement for the An-26, but
variants have found success as commercial freighters. Produced in tandem with
the An-72, the Antonov An-74 variant adds the ability to operate in harsh weather
conditions in polar regions. Other An-72 versions include the An-72S VIP
transport and An-72P maritime patrol aircraft.
An interesting design feature of the An-72 and -74 is the use of the Coanda
effect to improve STOL performance, utilizing engine exhaust gases blown over
the wing's upper surface to boost lift. The first flight was made in August,
1977. The power plant used is ZMKB Progress D36. The freighter can travel at a
speed of 330 knots / 611 km/h / 0.50 mach.
The An-72 bears some resemblance to an earlier aircraft, the experimental
Boeing YC-14.
