Realising that the export potential for theTupolev 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 fourLyulka AL-7 turbojets rated at 5,500kgf (53.9kN; 12,100lbf) thrust each, with two staggered engines in the root of each extended centre-section. The first prototype was flown on 11 March 1957.
Production of the Tu-110 was authorised at theKazan Aircraft Factory, 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 withSoloviev 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.
