The Tupolev Tu-110 (NATO reporting name: Cooker) was a jet airliner designed and built in the USSR, which saw its maiden flight in 1957.

Design and development[]

Realising that the export potential for the Tupolev Tu-104 was limited, the Council of Ministers issued directive No. 1511–846 on 12 August 1956, requiring the Tupolev Design Bureau to develop a four-engined version of the Tu-104, to enable the aircraft to safely cross large expanses of ocean, and improve safety on takeoff in case of engine failure.

The Tu-110 was a major redesign of the Tu-104, powered by four Lyulka AL-7 turbojets rated at 5,500 kgf (53.9 kN; 12,100 lbf) thrust each, with two staggered engines in the root of each extended centresection. The first prototype was flown on 11 March 1957.

Production of the Tu-110 was authorised at the , with an initial order for ten aircraft, but only three aircraft were completed before the programme was terminated. The production aircraft featured extended-chord wings and enlarged baggage holds, as well as seating for up to 100 passengers in an all-tourist class seating arrangement.

All four aircraft were converted to Tu-110Bs with Soloviev D-20 turbofan engines, in an attempt to improve the performance of the aircraft, but to no avail. No further orders were forthcoming and the four Tu-110Bs were used for experimental work on avionics, missile systems and boundary layer control systems, remaining active into the 1970s.

Variants[]

  • Tu-110 – The sole prototype of the Tu-110 (CCCP-L5600).
  • Tu-110A – Production aircraft with doubled seating capacity (all economy class), increased capacity baggage holds, increased area flaps and increased MTOW of 87,200 kg (182,320 lb). Three aircraft were built (CCCP-L5511 – L5513)
  • Tu-110B – Experimental medium-haul versions converted from the prototype and three production aircraft, fitted with four Soloviev D-20 turbofan engines.
  • Tu-110L – The prototype aircraft modified with boundary layer control supplied with bleed air from the D-20 turbofan engines.
  • Tu-110D – A projected medium-haul airliner with four D-20 engines in paired nacelles on either side of the rear fuselage,
  • Tu-117 – A projected military transport version with a rear fuselage loading ramp and defensive tail turret.
