The Tupolev Tu-330 was a proposed Russian medium-size transport aircraft developed by Tupolev since the early 1990s. The project was stopped around 2000s due to lack of funding and difficult economic situation of the Russian aircraft industry at the time.
The Tu-330 was to have a swept high-mounted wing design with two high-bypass ratio PS-90A engines mounted below the wings. An optional powerplant system has also been proposed, using NK-93 engines that can operate on LNG (liquefied natural gas) fuel. The aircraft was also designed for commonality with the Tu-204/Tu-214 civilian airliner series, in order to simplify production and minimize costs of manufacturing, maintenance and parts.
In addition to Tu-330, the following variants were proposed:[1]
