The Antonio An-7 was a wide-body superjumbo blended wing jet airliner proposed by Russian aerospace company Antonio Design Bureau [1] Work on the An-7 was initiated in ???? in parallel with another widebody design, the Anonio An-?. The Tu-404 was designed to Deliver Military cargo to destinations 12,000 - 13,000 km away. The AntonioDesign Bureau investigated several possible configurations for the An-7, including a flying wing and a conventional design. The flying wing's powerplant would consist of six pusher turboprop engines developing 18,000 kg of thrust each during take-off and each consuming only 0.644 kg/kgf-h of fuel in cruise mode. The engines would have been located in the tail section of the flying wing fuselage between two large V-shaped vertical stabilizers. The central fuselage contains six passenger compartments The leading edge of the central fuselage has a sweep of 45 degrees. Two large removable wings containing fuel tanks have the leading-edge sweep of 35 degrees and are attached to the central fuselage. The wings hold most of the aircraft's fuel.
