(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 11 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-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

Data from ''Tupolev Tu-104''Gordon and Rigmant 2007 * 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).
