The Tu-334 is a short-haul Russian passenger aircraft developed in the 1990s to replace the retiring Tu-154B, Tu-134 and Yak-42... For some reason, the serial production of the aircraft was not organized. As of June 2013, the project is frozen, but not formally closed.

The aerodynamic layout of the aircraft is a twin-engine low-wing turbojet with engines at the rear, with a T-shaped tail unit and a swept wing. The wing consists of supercritical profiles; specially profiled surfaces are mounted at the ends of the wing to reduce inductive resistance. The aerodynamic index of the aircraft is 16,7.

Widely used in modern aircraft design composite alloys and materials.

Wire control system with mechanical emergency backup. The control system provides wheel control pilots of aircraft and signals VSUPT automatic flight control.

The crew cabin is standardized as much as possible from the cabin Tu-204 / 214, and is designed on the principle of "dark cockpit" on the basis of modern ergonomic standards.

The fuselage of the Tu-334 in cross-section has the same appearance as the Tu-204, with which this aircraft is 60 percent unified, but has a shorter length.

Tricycle landing gear with bow strut. The fly-by-wire braking system was activated with its auto-switching to the mode of forcing the aircraft stop during an interrupted takeoff.

The aircraft is equipped with a complex of navigation and aerobatic equipment, which provides automatic or manual input of initial flight data, automatic selection of flight data, automatic aircraft driving in the airfield area along a programmed route, directorial control of the longitudinal and lateral movement of the aircraft, directorial and automatic landing approach and automatic landing, warning about reaching or approaching controlled flight parameters to the boundaries of operational tolerances.

The luggage compartment consists of 2 cargo compartments - the front compartment is 10 square meters and the rear compartment is 6,2 square meters. It was planned in the future to equip the aircraft with ladder doors released automatically.

The power plant consists of two turbofan engines D-436T1, made according to a three-shaft scheme. Power auxiliary unit - TA-12-60.

The passenger plane Tu-334 is really a quality device. It can calmly compete with world airlines, both in terms of technical parameters and comfort in flight. Indeed, not so long ago flying on one of them, was completely satisfied with both comfort and service. Many people say that these devices of our manufacture are very much below foreign analogues, I do not agree with this opinion at all. Better than worshiping the same Boeing you need to pay attention to our aircraft construction, especially as it has an excellent development. Yes, of course, our planes still have minor flaws, but mostly they are excellent aircraft. The biggest disadvantage is the quality of our aircraft, but the fact that when ordering such a machine, the customer will wait for her for months. And in turn, foreign cars are usually delivered very quickly in a few days or weeks.
