The Tupolev Tu-134 (NATO reporting name: Crusty) is a twin-engined, narrow-body, jet airliner built in the Soviet Union from 1966 to 1989. The original version featured a glazed-nose design and, like certain other Russian airliners (including its sister model the Tu-154), it can operate from unpaved airfields.
One of the most widely used aircraft in former Comecon countries, the number in active service is decreasing because of political intention and noise restrictions. The model has seen long-term service with some 42 countries, with some European airlines having scheduled as many as 12 daily takeoffs and landings per plane. In addition to regular passenger service, it has also been used in various air force, army and navy support roles; for pilot and navigator training; and for aviation research and test projects. In recent years, a number of Tu-134s have been converted for use as VIP transports and business jets. A total of 854 Tu-134s were built of all versions (including test bed examples) with Aeroflot as the largest user; by 1995, the Tu-134 had carried 360 million passengers for that airline.
Following the introduction of engines mounted on pylons on the rear fuselage by the French Sud Aviation Caravelle, airliner manufacturers around the world rushed to adopt the new layout. Its advantages included clean wing airflow without disruption by nacelles or pylons and decreased cabin noise. At the same time, placing heavy engines that far back created challenges with the location of the centre of gravity in relation to the centre of lift, which was at the wings. To make room for the engines, the tailplanes had to be relocated to the tail fin, which had to be stronger and therefore heavier, further compounding the tail-heavy arrangement.
During a 1960 visit to France, Soviet leader Nikita Khrushchev was so impressed by the quiet cabin of the Caravelle, that on 1 August 1960 the Tupolev OKB received an official directive to create the Tu-124A with a similar engine arrangement. The requirement was also driven by the need to replace slow, aging piston-engined Il-14s on domestic routes. In 1961, the Soviet state airline, Aeroflot, updated its requirement specifications to include greater payload and passenger capacity.
The first Tu-124A prototype, SSSR-45075, first flew on 29 July 1963. On 22 October 1963, the prototype British BAC One-Eleven, which had a similar layout, crashed with the loss of all crew while testing its stalling properties. The aircraft had entered pitch-up: the high-mounted tailplane became trapped in the turbulent wake produced by the wings (deep stall), which prevented recovery from the stall. As a result, the tailplane on Tu-124A was enlarged by 30% for greater control authority. Since Aeroflot's requirements dictated a larger aircraft than initially planned, the Soloviev Design Bureau developed the more powerful D-30 low-bypass turbofan engines. On 20 November 1963, the new airliner was designated Tu-134.
Design curiosities of the Tu-134 included a sharp wing sweepback of 35 degrees, compared to 2528 degrees in its counterparts. The engines on early production Tu-134s lacked thrust reversers, which made the aircraft one of the few airliners to use a brake parachute for landing. The majority of onboard electronics operated on direct current. The lineage of early Soviet airliners could be traced directly to the Tupolev Tu-16 strategic bomber, and the Tu-134 carried over the glass nose for the navigator and the landing gear fitted with low-pressure tires to permit operation from unpaved airfields.
Serial production began in 1966 at the Kharkov Aviation Production Association, and production of the Tu-124 was discontinued. The Tu-134 was designed for short-haul lines with low passenger traffic. Originally the aircraft had 56 seats in a single class configuration, or 50 seats in a two-class configuration.
In 1968, Tupolev began work on an improved Tu-134 variant with a 72-seat capacity. The fuselage received a 2.1-meter (6 ft 11 in) plug for greater passenger capacity and an auxiliary power unit in the tail. As a result, the maximum range was reduced from 3,100 kilometers to 2,770 kilometers. The upgraded D-30 engines now featured thrust reversers, replacing the parachute. The first Tu-134A, converted from a production Tu-134, flew on 22 April 1969. The first airline flight was on 9 November 1970. An upgraded version, the Tu-134B began production in 1980, with the navigator position abandoned, and seating capacity increased to 96 seats. Efforts subsequently began to develop a Tu-134D with increased engine thrust, but the project was cancelled.
In September 1967, the Tu-134 made its first scheduled flight from Moscow to Adler. The Tu-134 was the first Soviet airliner to receive international certification from the International Civil Aviation Organization, which permitted it to be used on international routes. Due to this certification, Aeroflot used most of its Tu-134s on international routes. In 1968, the first export customers, Interflug of East Germany and LOT Polish Airlines purchased the Tu-134. In 1969, the Tu-134 was displayed at the Paris Air Show.
In its early years, the Tu-134 developed a reputation for reliability and efficiency, especially when compared with previous Soviet designs. After the establishment of tougher noise standards in the ICAO regulations in 2002, the Tu-134 was banned from most western European airports for its high noise levels. In early 2006, 245 Tu-134s were still in operation, 162 of which were in Russia. After a fatal accident in March 2007, and at the instigation of Russian Minister of Transportation Igor Levitin, Aeroflot announced that it would be retiring its fleet, and the last Tu-134 was removed from service on 1 January 2008. Some are still in operations with Aeroflot subsidiaries on local routes within Russia. The Tu-134 also found a new life as a business jet with many having an expensive business interior installed. High fuel and maintenance costs are increasingly limiting the number used today.
Many Tu-134s have been preserved as memorials at airports throughout the former Soviet Union.
Some 69 Tu-134 have been destroyed in accidents and wars, of which 35 were non-fatal incidents (in one of the remaining 34 fatal incidents no one on the plane died).
