Short to medium range airliner
History
The advanced technology Tu-334 100 seat jet is being developed as a replacement for the ageing Tu-134.
Development of a replacement for the Tu-134 has been underway since the late 1980s, but it was not until August 1995 at the Moscow Airshow that the first prototype was displayed publicly. This aircraft had yet to fly at the time of writing.
The Tu-334 is based on the much larger Tu-204 twinjet with Tupolev using as many Tu-204 features in the new design as practical to reduce development time and costs. Examples of this include an identical flightdeck and a shortened Tu-204 fuselage. In addition the Tu-334's wing is based on the Tu-204's, although the latter's is a significantly larger unit.
Apart from commonality with the Tu-204, other notable Tu-334 design features are the rear fuselage mounted Progress D436 turbofans, Ttail and flybywire flight controls.
The Tu-334 is being developed in a number of versions. The first is the basic Tu-334100, while the Tu-334-120 is planned to powered by the BMW Rolls-Royce BR710-48. The Tu-354 (previously Tu-334200) is a stretched, 35m (115ft) long 110 to 126 seater (in a single class). Apart from the fuselage stretch, changes will include more powerful D436T2 or BR71555 turbofans, an increased span wing and four wheel main undercarriage units.
The Tu-334100D will be a longer range Tu-334-100 featuring the 100's standard length fuselage but with more powerful engines, increased fuel capacity, a higher max takeoff weight and the increased span wings of the Tu-334-200. Tupolev has also studied the Tu-334C, which would be a freighter.
Russian AP23 certification for the Tu-334-100 is planned for late 1999.
