The Ilyushin Il-90 was a twin-engine, widebody aircraft proposed by the Ilyushin Design Bureau. First mentioned at the Farnborough air show in 1988, the Il-90[1] was a replacement for the Ilyushin Il-62M long-range narrowbody airliner.[2] The Il-90 was designed to carry 200 passengers a distance of 5,900 to 7,000 nautical miles (11,000 to 13,000 kilometres; 6,800 to 8,100 miles). On a 540 nmi (1,000 km; 620 mi) sector, per-passenger fuel consumption would be 18 to 19 grams per kilometre (1.0 to 1.1 ounces per mile).[3] Powerplant choices included the NK-92, an 18,000-kilogram-force thrust (177-kilonewton; 40,000-pound-force) ducted propfan engine[4] that was related to the Kuznetsov NK-93.[5]
