The mid-range airliner Tu-204SM represents the further evolution of the Tu-204/Tu-214 family. The Tu-204SM is a deeply-modernized version of the Tu-204 using new PS-90A2 engines with better service life and reliability performance, with a two-member crew, and with upgraded or new, modern equipment.
The airplane meets Russian and international flight safety requirements, including the newly-introduced ICAO and Eurocontrol requirements, as well as the ETOPS-120. In its performance, the Tu-204SM matches its modern foreign counterparts.
The Tu-204SM airplane surpasses older versions of the Tu-204 family of airplanes in terms of flight and navigation performance and meets current international standards of efficiency, comfort, and maintainability, including the noise standards prescribed by ICAO Chapter 4.
The Tupolev Design Bureau started working on the design of a mid-range Tu-204, which was expected to replace the Tu-154 in mass production and operation by the end of the 20th century back in the 1970s. The Tu-204, which first took off on January 2, 1989, would see consistent development in a number of further versions of the baseline design, which would feature a highly-refined aerodynamic design of the airframe and structural elements allowing for the new airplanes to meet the highest international standards and compete with similar airplanes produced by international aircraft manufacturers.
In the 1990s and first half of the 2000s, PJSC Tupolev, jointly with the Central Institute of Aero-Hydrodynamics (TsAGI) and other industry organizations and companies, were considering a number of possible Tu-204/Tu-214 family development projects.
The creation of Tu-204/Tu214 airplanes was a crowning achievement of the Russian aircraft-production industry. For that work, the team of PJSC Tupolev was honored by the President of the Russian Federation with the State Prize of the Russian Federation in the field of science and technology, pursuant to a Presidential Decree dated September 9, 2004.
Work to design and produce the most recent version of the Tu-204, the streamlined medium-haul Tu-204SM, dates back to the early 2000s.
The first upgraded medium-range airliner Tu-204SM (MSN 64150) first took off at Ulyanovsk-Vostochny Airport on December 29, 2010. The airplane is produced by the Aviastar-SP aircraft production company at its production site in Ulyanovsk, Russia.
Flight certification tests of the modernized Tu-204SM were completed in May 2013. The new airliner was tested in low temperatures and high-intensity icing conditions, successfully completing trial operation in the Northeast Yakutia Region at the airport in the City of Yakutsk, which has historically been used as a test site for testing aircraft at extremely low temperatures. Certification test flights were also conducted at high temperatures in the United Arab Emirates, along with a series of takeoffs and landings to evaluate the airplane’s behavior on a wet runway.
A supplement to Type Certificate No.ST233-Tu-204-120SE/D10 was issued to PJSC Tupolev by the Aviation Register of the Interstate Aviation Committee on May 31, 2013.
The Tu-204SM boasts highly-improved operating performance. The airplane can carry 194 passengers over a distance of up to 4,800 km; the two-class cabin arrangement offers seating capacity for 174 passengers.
More than twenty new systems and components have been installed in the Tu-204SM. PCSC Tupolev has managed to create a civil airplane that matches its foreign counterparts in terms of performance while meeting international standards of efficiency, comfort and serviceability. The airplane can spend about nine hours in the air without refueling.
The modernized Tu-204SM features a number of significant differences from the older production of Tu-204s. First, it is equipped with PS-90A2 engines with 16,000 kgf thrust developed by the Perm Engine Plant with the participation of Pratt & Whitney, which received a type certificate from the IAC AR in December 2009. In contrast to the production version of PS-90A, the new modified engine is provided with a new high-pressure turbine, a new automatic-control system, and has some other incorporated modifications that ensure compliance with modern airworthiness and environmental requirements. PS-90A2 engines allow the Tu-204SM to compete nearly on par with its foreign rivals. Furthermore, a considerable decrease in lifecycle cost and improvement in engine reliability has been achieved.
The Tu-204SM is also equipped with a new TA-18-200 auxiliary power unit produced by PJSC Aerosila, which offers improved fire resistance.
This version comes with an all-English flight desk, except for three airplanes intended solely for domestic flights in Russia. Additionally, the airplane has been provided with an upgraded air-conditioning system that adds comfort for passengers and crew.
Pursuing the goal of achieving a reduction in empty weight, the designer has completed a large scope of work to refine the structure, introduce new materials and introduce newer and lighter aircraft systems. In particular, elevators, rudders and wing high-lift devices are made using carbon fiber composite materials from Hexcel. A lighter landing gear developed by Samara-based PJSC Aviaagregat has been installed.
Due to the substantial modernization of airborne equipment (new integrated display and alerting system, and a new flight and thrust-control computer system, rearranged panels and boards in the flight crew compartment), it was possible to design the new flight deck without a Flight Engineer’s station. Upgraded avionics made it possible to use new automatic control modes, in particular, Cat. IIIA automatic approach, director-controlled take-off, etc. The flight crew compartment is fitted with new miniature control wheels.
Specially for the Tu-204SM airplane, the PNK-204 flight control and navigation system was designed by Radio-Electronic Technologies Concern (KRET), a member of Rostec State Corporation.
The Flight Management System and automatic control system have been developed by the Moscow Institute of Electromechanics and Automation, a member of KRET. The majority of instrumentation and components of the integrated flight control and navigation system are produced by another KRET enterprise — Ulyanovsk Design Bureau. The number of PNK-204 replaceable units has been cut in half and total number of avionics-equipment items in the Tu-204SM reduced by a factor of five, resulting in a total weight reduction of 300 kg.
The airplane’s overall weight reduction was also furthered by the modernization of electrical and lighting equipment — incandescent bulbs in taxi and landing lights were replaced with LED and xenon bulbs. What’s more, the reliability of units was improved, while the labor intensity and cost of avionics maintenance were reduced.
As a part of the Tu-204SM Project, new methods of using simulator training facilities integrated into training and practicing complexes with computer networks, as well as multi-tier training tools, were developed. Examples include: automated training systems as part of computer-based training classrooms, theoretical training tools, cockpit procedure trainers, initial and basic ground (simulator) crew training facilities for particular in-flight procedures training, and full flight simulators for mastering the airplane in all of its operating modes. The comprehensive and staggered use of those training and practice facilities allows for flight crew training on the ground with little or no use of actual airplanes.
