Tupolev TU-334

Tu-334 is a Russian regional jet aircraft, developed in the 90s to replace the outdated Soviet Tu-134 and Yak-42 airliners. For several reasons, the serial production of the aircraft was not organized – the project was frozen.


Work on the Tu-334 began back in the late 1980s, but development and production were slow due to financial problems.

In the late 1980s, to replace the outdated regional aircraft, it was decided to begin developing a new generation aircraft. Initially, it was planned to launch production at two plants – in Russia at KAPO named after S. P. Gorbunov and in Ukraine at the Kyiv plant, but subsequently, it was decided to produce it only in Russia.

The prototype made its first flight in 1999 under the command of A.N. Soldatenkova. Two flight specimens were made, which, subsequently, were repeatedly exhibited at various air shows. In 2003, the Tu-334-100 baseboard was introduced as a model for mass production. However, by 2007 5 gliders were made (2 of which were intended for static tests).

December 30, 2003, the aircraft received a certificate of type ST231-Tu-334-100. In 2005, a series of tests were conducted to expand the expected operating conditions.

In 2005, the Government of the Russian Federation approved a decree on mass production at KAPO Gorbunova. However, the decision was not implemented – the program was not included in the Federal Target Program. The project was frozen, losing a state tender for a regional airliner to another aircraft – SSJ 100.


The aerodynamic design is a low wing with a rear-engine, swept wing, and T-tail. Supercritical profiles and winglets form the wing. The design of the aircraft is widely used in modern composite materials and alloys.

The aircraft and, first of all, the cockpit is unified by Tu-204/214 family aircraft. The fuselage also has the same cross-section as the Tu-204 but has a shorter length.

Tricycle landing gear with bow stance. An electric brake system is engaged with its automatic switching to the forced stop mode of the aircraft during interrupted take-off.

The luggage compartment consists of two cargo compartments – the front 10 m³ and the rear 6.2 m³. In the future, it was planned to equip the aircraft with manufactured ramp doors.

Power plant – two turbofan engines D-436T1, made according to the three-shaft scheme. Also, in the tail of the APU installed.
