Development
The
Tupolev confirmed the use of the D-436 for the turbofan version shortly afterward.
Information about the propfan engine began to be revealed during the second quarter of 1990, although the details were often conflicting. In April 1990, while announcing the interim aircraft's service entry date of 1993, Tupolev's chief designer said that the ultrahigh bypass engine to be used would be a Lotarev (now renamed to the Progress design bureau) propfan resembling the
Work commenced on the Tu-334 in the early 1990s, but proceeded slowly due to funding problems arising from the
Development remained slow due to protracted budget problems. In turn, the certification of the aircraft and its planned entry into serial production was delayed multiple times. As of December 2006 there were firm orders for the Tupolev Tu-334 from seven airlines, including Atlant-Soyuz Airlines and there were letters of intent from 24 airlines to obtain another 297 airplanes.[13][14] The price per unit for the business version is estimated to be around $43–44 million.[citation needed]
One of the projected customers for the type was
As late as 2008, Tupolev reported that a total of about 100 airlines had expressed an interest in placing orders for Tu-334s; on 31 July 2008, Tupolev Managing Director Sergei Ilyushenkov announced that production was targeted to begin no later than January 2009.[citation needed] However, this date also passed without any reported progress on Tu-334 serial production.
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, which led to the formation of United Aircraft Corporation. In mid-2009, the decision was taken to not continue with the Tu-334 programme and instead focus efforts on the
