The work on the Tu-404 was initiated in 1991 along with another large passenger aircraft project - the Tu-304. The Tu-404 was designed to transport
more than 1,200 passengers to destinations 12,000 - 13,000 km away. The Tupolev Design Bureau was working on several variants of the new heavy
passenger transport.
One of the possible configurations for the aircraft was that of a flying wing. In this configuration the aircraft'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 are located in the tail section of the flying wing fuselage between two large V-shaped vertical stabilizers.
The central fuselage contains six passenger compartments accommodating 1214 passengers. 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.
the craft is desinged to be powerd by four NK-44 or rolls royce"trent"engines installed on under wing pulons.the aircrafts undercarriage cosists of
several carts with multiple wheels in each cart.it is retracted into the central fuselage section of the aircraft
