The Tupolev Tu-124 was
designed to fill an Aeroflot need for a turbine- powered,
short/medium-range airliner to replace the piston-engined Ilyushin
Il-14 in service on important routes. A capability for a new aircraft
to operate from shorter length or unpaved runways was an essential part
of the requirement. Engine designers discovered that improved
combustion chambers and increased compression ratios offered lower fuel
consumption, but it was the development of turbofan engines that
changed the economics of pure jet engines, and, at the same time,
considerably reduced noise pollution
at airport environments.
The Tu-124s entered service with Aeroflot on November 10, 1962 on the
Moscow to Ul’yanovsk route. There was passenger capacity for 44,
however the Tu-124V (introduced at a later date) seated 56. It is
believed about 100 of the Tu-124s were built: of these, three were
operated by Ceskoslovenske
Aerlinie, two to East Germany’s Interflug, and others to air forces of
East Germany, India and Iraq. By the mid 1980's, about 80 remained in
service with Aeroflot.
