Tupolev Tu-124
The Tupolev Tu-124 (NATO reporting name: Cookpot) was a 56-passenger short-range twinjet airliner built in the Soviet Union.
== Design and development ==
Developed from the medium-range Tupolev Tu-104, the Tu-124 was meant to meet Aeroflot's requirement for a regional airliner to replace the Ilyushin Il-14 on domestic routes. Resembling a 75% scaled-down Tu-104, the two were hard to tell apart at a distance but it was not a complete copy of the Tu-104. The Tu-124 had a number of refinements, including double-slotted flaps, a large centre-section airbrake and automatic spoilers. Unlike the Tu-104, the wing trailing edge inboard of the undercarriage was unswept.〔("TU-124 – Details of Tupolev's Medium Range Turbofan" ) ''Flight International'', 16 August 1962, pp.229–230, article includes drawings〕
The Tu-124 retained a drogue parachute to be used in an emergency landing or landing on a slippery surface and had low pressure tires to aid operation from unpaved airfields.〔Gunston 1995, p. 433.〕〔Stroud 1968, pp. 227–229.〕 As on the Tu-104 the engines were integrated into the wings, but the turbofan engines were more fuel efficient. The placement of the engines amplified vibrations, which affected the comfort of the passenger cabin, and also the fatigue lifetime of the wing assembly.
The standard seating of the basic version was 44 seats. The first of two prototype, SSSR-45000 (C/N 0350101) made its first flight from Zhukovsky airfield on 24 March 1960. The second prototype, SSSR-45001 (C/N 0350102), followed in June 1960. Two other airframes served as a static test cells. Testing was successful, and the aircraft entered production at Factory 135 at Kharkov, Ukraine, replacing the Tu-104 in production.〔〔Duffy and Kandalov 1996, p. 134.〕 Deliveries to Aeroflot began in August 1962, with the type operating its first scheduled passenger service, between Moscow and Tallinn in Estonia, on 2 October 1962.〔Duffy and Kandalov 1996, pp. 134–135.〕
