The first instance of the upgraded medium-range passenger aircraft Tu-204CM (production No.64150) first took off at 13:25 on December 29, 2010, in Ulyanovsk at the Ulyanovsk Vostochny airport.
The developer of the Tu-204SM aircraft is Tupolev OJSC. The liner is equipped with PS-90A2 engines, which have the characteristics of world-class engines. The reliability of the engine is 1.5-2 times higher than the prototype PS-90A. This aircraft can be in the air without refueling for about nine hours. The Tu-204SM flight range is about 4 thousand km, with a 2-class layout of 174 seats. The aircraft is equipped with new navigation, radio communications, instrumentation, which will allow the crew to control the aircraft not from three, as it was before, but from two people.
The upgraded Tu-204CM has some significant differences from the previously produced Aviastar serial Tu-204-100. Firstly, PS-90A2 engines with a thrust of 16,000 kgs developed in Perm with the participation of the American company Pratt-Whitney will find use in it, which received a certificate of type AR MAK in December 2009. Unlike the serial PS-90A, the modified engine is equipped with a new high-pressure turbine, a new automatic control system, and has several other significant improvements, which ensures the satisfaction of modern world requirements for airworthiness and environmental protection. At the same time, a significant reduction in the life cycle cost and an increase in engine reliability is provided. A new auxiliary power unit TA-18-200, manufactured by the Aerosila OJSC, is also used on Tu-204SM
To reduce the mass of an empty aircraft, several measures are being introduced to improve the design, use new materials, and more modern and lightweight on-board systems. In particular, the use of elevators and directions, as well as wing mechanization made of carbon-fiber composite materials manufactured by Hexcel, a lightweight chassis for the development of Samara Aviation Unit OJSC, and a more advanced digital-controlled air conditioning system are envisaged. The flight crew of the aircraft was reduced from three to two people (flight engineer was excluded from its composition), which became possible due to a significant modernization of on-board equipment. A new integrated display and alarm system KSEIS-204E, a new flight and traction control system VSUPT-85-204 were installed, and virtually all shields and consoles in the cockpit were redesigned. The upgraded avionics made it possible to implement new automatic control modes, in particular, an IIIA automatic approach (Tu-204-100 avionics provided only Category II), director take-off, etc. New mini-helms are used in the crew cabin.
Modernization of the power supply system and lighting equipment also helps to reduce the weight of the aircraft: incandescent bulbs are replaced by LEDs and xenon lamps (in taxi and landing lights). Thanks to all the implemented changes, the mass of an empty aircraft should decrease from 60 to about 58 tons, while the maximum take-off and landing mass, on the contrary increase: from 103 to 105 tons and from 88 to 89.5 tons, respectively. The estimated assigned resource Tu-204CM should increase to 60,000 hours, 30,000 landings, and 25 years of operation (today’s Tu-204-100, respectively, 45,000 hours, 25,000 landings, and 20 years).
Certification tests of the Tu-204CM were completed in 2011 when the delivery of serial aircraft to the start customer Atlant-Soyuz Airlines can begin.
Within the framework of the Tu-204CM project, new directions in the use of training equipment have also been developed integrated by a computer network into educational training complexes (UTK) and multilevel teaching aids. Such as automated training systems as part of computer training classes theoretical training facilities; procedural simulators means of initial and basic practical ground (simulator) training of crews for performing individual flight procedures; complex simulators for the development of aircraft in all modes of its operation. The complex and phased use of the listed training facilities allows you to train crews on the ground with virtually no use of real aircraft.
