Tupolev Tu-104

The Tupolev Tu-104 (NATO reporting name: Camel) was a twin-engined medium-range turbojet-powered Soviet airliner. After the British de Havilland Comet, Canadian Avro Jetliner, and Sud Caravelle, the Tu-104 was the fourth jet airliner to fly, and the second to enter regular service. Its arrival in London during a 1956 state visit shocked Western observers.

Development

At the beginning of the 1950s, the Soviet Union's Aeroflot airline desperately needed a modern airliner with better capacity and performance than any other Soviet plane 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 first version was more similar to the Tu-16 and it got square windows like the early De Havilland Comet, but this was later changed before the airplane made its maiden flight. The airplane was pressure tested in a watertank. The wings, engines, and tail surfaces of the Tu-16 were retained in the airliner, but the new design adopted a wider, pressurised fuselage to accommodate 50 passengers. The first flight of first production Tu-104 was on November 6 1955 at Kharkiv plant in Ukraine. It was fitted with a drogue parachute which could shorten the landing run with up to 400 meters.

By the time production ceased in 1960, about 200 had been built. Aeroflot did not retire the Tu-104 from civil service until 1979, the aircraft continued to serve in in the Soviet Air Force until 1981 when a crash deemed it unsafe, last flight of the type was in 1986 a ferry flight to a museum. CSA Czechoslovak Airlines, the Czechoslovak national airline, bought six (four new and two used) of Tu-104As configured for 81 passengers. CSA crashed three of their aircraft.

Following its removal from civil service, several aircraft were transferred to the Soviet military, which used them as staff transports and to train cosmonauts in zero gravity.

Variants

• Tu-104 - initial version seating 50 passengers.
• Tu-104A - Continuing improvements in the Mikulin engines permitted significant growth in the Tu-104 resulting in a 70-seater variant. The Tu-104A became the definitive production variant.
  • Tu-104D - Tu-104A airframes rebuilt to accommodate 85 passengers
  • Tu-104V - Tu-104A airframes rebuilt to accommodate 100 passengers
• Tu-104B - Further improvements were attained with the stretched Tu-104B fitted with new engines, the Mikulin AM-3M-500 turbojets, and able to accommodate 100 passengers.
• Tu-104E - Record breaking version.
• Tu-104LL Flying testbed. Armed heavy Air-Air missiles tests.
• Tu-107 - Military transport version with rear loading ramp and defense cannon turret.
• Tu-110 - Four-engined transport prototype.
