The Sukhoi KR-860 (Kryl'ya Rossii or Wings of Russia),[1] earlier named the SKD-717, was a double decker wide-body superjumbo jet aircraft proposed by Russian aerospace company Sukhoi.[2]
Development
The design had a maximum weight of about 650 tonnes, a payload of about 300 tonnes, the main deck having a 12-abreast seating with three aisles, while the upper deck had 9-abreast seating with two aisles. It was intended to carry 860 to 1000 passengers. Entry would be through conventional fuselage doors or forward and aft ventral escalators. The wing design had winglets and a fold outboard of the outer engine.[3] For comparison the Antonov An-225 has a maximum weight of 600 tonnes and a payload is 250 tonnes. A 1/24 scale model was shown[4][5][6] at the 1999 Paris Air Show.[7] If built, the aircraft would have been the world's largest, widest, and heaviest airliner.[8]
The concept for the aircraft began in the 1990s with a forecast programme cost of US$10 billion (early published figures were US$4–5.5B) and called for the first aircraft to be built before 2000. With an estimated price per unit of about US$160–200 million (an earlier published estimate was US$150 million) the market was forecast for a total of 300 aircraft, with production planned for the Kazan Aircraft Production Association facility. Initially designed for the carriage of passengers, later a KR-860T (T stands for Tanker) version was proposed for use as an aerial Liquefied natural gas (LNG) tanker for far-north regions. Taking advantage of the presence of LNG on the aircraft, the design proposed using LNG to fuel the turbines, rather than conventional Jet fuel, like on the Tupolev Tu-206.[9]
The project did not proceed beyond the stage of marketing models.
