MULTI-PURPOSE FLYING VEHICLE (VERSIONS) Russian patent published in 2000 - IPC

FIELD: aeronautical engineering. SUBSTANCE: flying vehicle has fuselage high-set and low-set wings connected by means of pylons over their tips, pusher propulsor mounted in tail section of fuselage. Low-set wing is swept-back wing having positive dihedral V angle. High-set wing is swept-forward wing having negative dihedral V angle; it is provided with elevators. Separation of chords of root and tip sections of wings in height and length are determined from the following relationship: root sections - no less than root chord of wing; tip sections - comparably with tip chord of wing. Pylons have aerofoil profile forming tensile stress in longitudinal direction of panel of low-set and high-set wings. High-set wings are connected in root over central axis of pusher propulsor. Flying vehicle may have wide fuselage. EFFECT: enhanced stability; controllability; fatigue strength; safety; ease of pilotage, etc. 15 cl, 12 dwg
