History Public Joint Stock Company Tupolev,
Tupolev Tu-334 was a Russian short-to-medium range airliner
The Tupolev Tu-334 (Russian: Туполев Ту-334) was a Russian short-to-medium range airliner project that was developed to replace the aging Tu-134s and Yak-42s in service around the world. The airframe was based on a shortened Tu-204 fuselage and a scaled-down version of that aircraft's wing. Unlike the Tu-204, however, the Tu-334 has a T-tail and engines mounted on the sides of the rear fuselage instead of under the wings. With the nationalisation of the Russian aircraft companies in 2009 to form United Aircraft Corporation it was decided not to continue with the programme
Development
The Tupolev Design Bureau introduced the Tu-334 in early 1989 as an eventual propfan-powered airliner to potentially enter service for Aeroflot in 1995. However, it would have an interim turbofan-powered version that would begin airline service around 1991–1992. Consuming about 20 percent less fuel than the best Soviet turbofan, the propfan engine would be a then-unnamed geared powerplant from the Lotarev engine design bureau. The engine would have a thrust specific fuel consumption (TSFC) of 13 g/(kN⋅s) (0.46 lb/(lbf⋅h)), resulting in a per-passenger aircraft fuel consumption rate of 13 grams per kilometre (0.74 ounces per mile). The turbofan-powered version of the Tu-334 would use Lotarev D-436T engines with a TSFC of 18 g/(kN⋅s) (0.62 lb/(lbf⋅h)) and a bypass ratio of 6.5, and it would consume 20 g/km (1.1 oz/mi) per passenger. The propfan Tu-334 would seat 104-137 passengers, compared with 86-102 passengers for the shorter, turbofan Tu-334.

In 2009, with the project years behind the projected schedule and only two examples built and flying ten years after the first flight, the Tu-334 came under review during the rationalisation of the Russian aircraft companies.
