The Tupolev Tu-104 (NATO reporting name: Camel) was a twinjet medium-range narrow-body turbojet-powered Soviet airliner. It was the second to enter regular service, behind the British de Havilland Comet, and was the only jetliner operating in the world from 1956 to 1958, when the British jetliner was grounded due to safety concerns.[1]

In 1957, Czechoslovak Airlines – ČSA, (now Czech Airlines) became the first airline in the world to fly a route exclusively with jet airliners, using the Tu-104A variant between Prague and Moscow. In civil service, the Tu-104 carried over 90 million passengers with Aeroflot (then the world's largest airline), and a lesser number with ČSA, while it also saw operation with the Soviet Air Force. Its successors included the Tu-124, the Tu-134 and the Tu-154.

Design and development[]

At the beginning of the 1950s, the Soviet Union's Aeroflot airline needed a modern airliner with better capacity and performance than the piston-engined aircraft then in operation. The design request was filled by the Tupolev OKB, which based their new airliner on its Tu-16 'Badger' strategic bomber. The wings, engines, and tail surfaces of the Tu-16 were retained with the airliner, but the new design adopted a wider, pressurised fuselage designed to accommodate 50 passengers. The prototype build in MMZ 'Opit' first flew on June 17, 1955 with Yu.L. Alasheyev at the controls. It was fitted with a drag parachute to shorten the landing distance by up to 400 metres (1,300 ft), since at the time not many airports had sufficiently long runways.[1] The first serial TU-104 took off on 5 November 1955.[2]

The Tu-104 was powered by two Mikulin AM-3 turbojets placed in the wing roots (resembling the configuration of the de Havilland Comet). The crew consisted of five people: two pilots, a navigator (seated in the glazed "bomber" nose), a flight engineer and a radio operator (later eliminated). The airplane raised great curiosity by its lavish "Victorian" interior – so-called by some Western-hemisphere observers – due to the materials used: mahogany, copper and lace.[1]

Tu-104 pilots were trained on the Il-28 bomber, followed by mail flights on an unarmed Tu-16 bomber painted in Aeroflot colors, between Moscow and Sverdlovsk. Pilots with previous Tu-16 experience transitioned into the Tu-104 with relative ease. The Tu-104 was considered difficult to fly, as it was heavy on controls and quite fast on final approach, and at low speeds it would display a tendency to stall, a feature common with highly-swept wings. Experience with the Tu-104 led the Tupolev Design Bureau to develop the world's first turbofan series-built airliner, the Tupolev Tu-124, designed for local markets, and subsequently the more commercially successful Tu-134.[citation needed]

Operational history[]

On 15 September 1956, the Tu-104 began revenue service on Aeroflot's Moscow-Omsk-Irkutsk route, replacing the Ilyushin Il-14. The flight time was reduced from 13 hours and 50 minutes to 7 hours and 40 minutes, and the new jet dramatically increased the level of passenger comfort.[1] By 1957, Aeroflot had placed the Tu-104 in service on routes from Vnukovo Airport in Moscow to London, Budapest, Copenhagen, Beijing, Brussels, Ottawa, Delhi, and Prague.[citation needed]

In 1957, ČSA Czechoslovak Airlines became the only export customer for the Tu-104, placing the aircraft on routes to Moscow, Paris, and Brussels. ČSA bought six Tu-104As (four new and two used examples) configured for 81 passengers. Three of these aircraft were subsequently written off (one due to a refueling incident in India and another to a pilot error without fatalities).[1]

In 1959 a Tu-104 was leased to Sir Henry Lunn Ltd. (Lunn Poly) of London which used the aircraft to transport holiday-makers to Russia with a 4.5 hour flight time.[citation needed]

Whilst the Tu-104 continued to be used by Aeroflot throughout the 1960s and 1970s, the safety record of the aircraft was poor in comparison to subsequent jet airliners (16 of 96 aircraft were lost in accidents). The Tu-104 was unreliable, heavy, very unstable with poor control response, with an inclination to Dutch roll. Poor design aerodynamics of the wings resulted in a propensity to stall with little or no warning and a dangerous tendency to pitch-up violently before stalling and entering an irrecoverable dive. Due to the fear of inadvertent stalls aircrew would fly approaches above the recommended approach speed, landing at 270–300 km/h (170–190 mph), nearly 50 km/h (31 mph) faster. At least two accidents were attributed to the pitch-up phenomenon, prompting changes to the design of the aircraft and operating procedures, but the problem remained. Aeroflot retired the Tu-104 from civil service in March 1979 following a fatal accident at Moscow, but several aircraft were transferred to the Soviet military, which used them as staff transports and to train cosmonauts in zero gravity. After a military Tu-104 crash in February 1981 killed 52 people (17 were senior army and naval staff), the type was permanently removed from service. The last flight of the Tu-104 was a ferry flight to Ulyanovsk Aircraft Museum in 1986.[citation needed]

Data from: [1]

  • Tu-104 – initial version seating 50 passengers. It used two Mikulin AM-3 turbojet engines, each with 6,735 kilograms (14,848 lb) of thrust. 29 airframes were built.
  • Tu-104 2NK-8 – Proposed version powered by two Kuznetsov NK-8 turbofan engines.
  • Tu-104A – Improved version appearing in June 1957; continued improvements of the Mikulin engines (Mikulin AM-3M each with 8,700 kilograms (19,200 lb) of thrust) permitted significant growth in capacity, resulting in a 70-seater variant. The Tu-104A became the definitive production variant. On 6 September 1957, it flew with 20 t of payload at 11,211 metres (36,781 ft) of altitude. On 24 September 1957, it reached 970.8 km/h (603.2 mph) average speed with a two tonne payload. A total of 80 airframes were built, of which six were exported to Czechoslovakia.
  • Tu-104AK – testbed aircraft for Zero-G cosmonauts' training and testing the Soviet space programme equipment
  • Tu-104A-TS – Five Tu-104A's converted to freighter/medevac aircraft.
  • Tu-104B – Further improvements made by stretching fuselage 1.2 metres (3 ft 11 in) and fitting new Mikulin AM-3M-500 turbojets (9,700 kilograms (21,400 lb) of thrust each). The Tu-104B was able to accommodate 100 passengers. This variant took advantage of the newer fuselage from the Tu-110 and the existing wings. It began revenue service with Aeroflot on 15 April 1959 on the Moscow-Saint Petersburg route. A total of 95 airframes were built. Most were later rebuilt to Tu-104V-115 standard.
  • Tu-104B-TS – Six Tu-104B's converted to freighter/medevac aircraft.
  • Tu-104D – VIP version with two sleeper cabins forward and a 39-seat cabin aft.
  • Tu-104D-85 – Tu-104A airframes rebuilt to accommodate 85 passengers.
  • Tu-104D 3NK-8 – Project powered by three NK-8 engines, precursor of Tu-154.
  • Tu-104E – A higher performance Tu-104 powered by RD-16-15 engines giving better fuel economy and greater thrust. Two prototypes were converted from Tu-104B's CCCP-42441 and CCCP-42443. The program was cancelled in the mid-1960s in favor of the Tu-154.
  • Tu-104G – VIP version for the Federal government with two VIP cabins forward and a 54-seat cabin aft.
