ARRANGEMENT AND AERODYNAMIC STUDIES FOR LONG-RANGE AIRCRAFT IN “FLYING WING” LAYOUT

摘要

The “flying wing”(FW) configuration is one ofthe most promising alternatives to conventional“tube and wing” scheme. New concept ofmoderate capacity long-range FW aircraft isinvestigated in TsAGI over the last years.Various arrangements have been studied withdifferent passenger accommodation, enginepositions, control system architecture, etc.Special aerodynamic model with flexiblearrangement of tail units, wing tips and nacelleshas been tested in several wind tunnels. Thispaper presents some results of the experimentalstudies alongside with accompanying CFDresults.
