The Antonov An-71 ( NATO code name : Madcap ) is the prototype of a Soviet early warning aircraft . The machine is a variant of the Antonov An-72 and corresponds to this in the design.
The main differences are the modified vertical tail fin with a negative sweep that carries the early warning radar, more powerful main engines and a third Kolessow / Saturn RD-36A engine in the rear fuselage section.
history
Work began in the spring of 1983 under the direction of Pyotr Balabuyev. The two prototypes of the An-72 were converted for the first two test models. The first roll tests took place on July 5, 1985, seven days later, on July 12, in 1985 Alexander Tkachenko took off at 2:30 p.m. with the first prototype with the aircraft registration number SSSR-780151 for the first flight. The second machine (registration number SSSR-780361) started for the first time on February 28, 1986. A total of only three prototypes were produced, the fourth was not completed in the specified period. Parts of the fourth machine were used to repair the first prototype, which was damaged in a crash landing. The first two prototypes were generally used for flight tests, the third was used for static tests in the Kharkov aircraft factory . The program was discontinued in 1990 after a total of 749 flights in favor of the Yakovlev Jak-44 .
The first prototype is on the premises of the manufacturer on the Kiev Sviatoshyn Airfield (UKKT), ( 50 ° 28 '23.7 " N , 30 ° 23' 5.9" O )
