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

摘要

The “flying wing”(FW) configuration is one of the most promising alternatives to conventional “tube and wing” scheme. New concept of moderate capacity long-range FW aircraft is investigated in TsAGI over the last years. Various arrangements have been studied with different passenger accommodation, engine positions, control system architecture, etc. Special aerodynamic model with flexible arrangement of tail units, wing tips and nacelles has been tested in several wind tunnels. This paper presents some results of the experimental studies alongside with accompanying CFD results.
