The Chaplygin Siberian Aeronautical Research Institute's re-engined Antonov An-2 made its public debut last month at the Gelendzhik air show on Russia's Black Sea coast.
The Novosibirsk-based institute has replaced the single-engined aircraft's ASh-62 nine-cylinder radial engine with a Honeywell Aerospace TPE-331 turboprop and a Hartzell five-blade propeller.
The upgrade is designed to breathe new life into the 65-year-old design by cutting its operating costs and boosting its performance characteristics.
