Turboprop aircraft are generally deployed on regional or short-haul flights, with medium and long-haul services typically being the domain of jet-powered aircraft. A key reason for this is that the latter type tends to perform much better in terms of speed and range. However, one notable outlier to this trend was the Tupolev Tu-114.
Based on a bomber
The Tupolev Tu-114 was a product of the 1950s, a time when post-war innovation was revolutionizing the world of aviation. The design resulted from a directive issued in August 1955 when the Soviet Union's Council of Ministers and Ministry of Aircraft Production requested an airliner based on the Tupolev Tu-95.
The Tu-95 was a long-range strategic bomber that first flew in November 1952. Still in use today (the Russian Aerospace Forces plans to keep them in service until at least 2040), the aircraft's swept wings and powerful contra-rotating propeller engines were conducive to high-speed, long-range flight. As such, the Council wanted Tupolev to harness these advantages to create an aircraft with a range of 8,000 km (4,971 miles). In the end, the company comfortably exceeded this target.
While Tupolev directly transferred certain design elements of the Tu-95, it fitted the Tu-114 with a significantly wider fuselage. This greatly increased the aircraft's weight, resulting in an increase in the surface area of its landing flaps. The Tu-114 ultimately made its first flight in November 1957 and entered service in April 1961 on the Moscow to Khabarovsk route. While still in its testing phase in 1959, the Tu-114 carried Nikita Khrushchev on his first trip to the US.
A strong performer
The Tu-114 was a sizeable aircraft, clocking in at 54.1 m (177 ft) long and 51.1 m (167 ft) wide. Standing at 15.44 m (50 ft) tall, this imposing turboprop aircraft could carry up to 220 passengers, as well as a 5/6-person flight crew and 10 flight attendants. Its 870 km/h (540 mph) maximum speed was comparable to jet aircraft, and its range peaked at an impressive 8,950 km (5,560 miles).
When the Tu-114 entered service, it initially did so on a domestic basis with Aeroflot. However, international destinations were soon added to its repertoire, allowing the type to fully showcase its long-range, high-speed capabilities. The airline deployed the Tu-114 on various intercontinental routes from Moscow Sheremetyevo Airport (SVO), including to Havana and Montreal.
The aircraft also flew to Tokyo, in partnership with Japan Airlines, with a unique two-class configuration seating a total of 105 passengers. At least one pilot and five of the ten flight attendants were from Japan Airlines, although the service ended in 1969 after just two years.
However, Tupolev only ended up producing 32 examples of the Tu-114, as the advent of the jet age led to its replacement by the likes of the Ilyushin Il-62. Nonetheless, it was ranked highly in terms of fuel efficiency and was revered for its reliability and safety, having only been involved in a single fatal accident - Aeroflot flight 065 from Moscow Sheremetyevo to Brazzaville, with stopovers in Conakry and Accra in 1966. On take-off, the aircraft struck snow piled by the side of the runway, which sent it off course, and in the subsequent fire, around half of those onboard perished.
Short but sweet
Just as the Tu-114 had made history as the world's fastest turboprop, it was replaced by the similarly ground-breaking Ilyushin Il-62, which, at the time of its launch, was the largest jet aircraft in the world. This contributed to the Tu-114's decline, and with Aeroflot's examples having largely reached their 14,000-hour airframe fatigue limit by the mid-1970s, the aircraft retired from commercial service in 1976. By this time, the imposing aircraft had carried more than six million passengers.
One of Aeroflot's Tu-114s was later put on display at the Central Air Force Museum in Monino, just outside of Moscow. The Soviet military continued to fly the Tu-114 until 1991.
Today, Sheremetyevo Airport remains Aeroflot's largest hub, although the carrier's route network has been significantly cut due to sanctions imposed as a result of the conflict in Ukraine. Among the limited number of international destinations still operated by Aeroflot are Hong Kong (HKG), Dubai (DXB), and Beijing (PKX).
