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 take-off in case of engine failure.
The Tu-110 was a major re-design 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 centre-section. The first prototype was flown on the 11th of March 1957.
Production of the Tu-110 was authorised at the Kazan 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-110B's 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-110B's were used for experimental work on avionics, missile systems and boundary layer control systems, remaining active into the 1970s.
