The first flight of the prototype, which was given the name TR-301/117performed on October 1, 2025 and lasted about 10 minutes, according to a Russian Telegram channel TAKE-OFF.
Manufacturer Technoregion has for years focused on the modernization and remotorization of the An-2. In this new configuration, the machines used are TV2-117which is usually mounted on the Mi-8t helicopter.
Conversion and performance
To adapt the engine to the aircraft, engineers changed it to single shaft turboprop. The free turbine is removed and the gearbox is connected directly to the compressor.
After modification, power dropped from 1,500 to approx 900 horsepower — a reduction of about 40%. Nevertheless, Technoregion is confident that the new model TR-301/117 will surpass the previous version equipped with a Czech-made engine M601 (720 hp).
Basic model TR-301 is a lightweight version of the An-2, without lower wings and with tubular reinforcement on the upper wings. According to Russian Federal Air Transport Agencynine of these aircraft have received airworthiness certificates, and another sixteen are officially registered.
Experimental history
Before selecting the TV2-117 engine, Technoregion had tested several power alternatives, including the Czech engine M601helicopter engine GTD-350car engine Zmz-409and even diesel engines from Kamaz.
Now, the company considers the use of the TV2-117 as the most promising solution to revive the An-2 fleet — an aircraft that has been widely used in agricultural aviation, regional transport and utility missions in Russia since the 1940s.
