AIRCRAFT OF LIFTING FUSELAGE AERODYNAMIC CONFIGURATION WITH AERODYNAMIC STALL FENCES

摘要

aviation; passenger and transport aircraft of "lifting fuselage: aerodynamic configuration. SUBSTANCE: aircraft has fuselage in form of lifting surface at low aspect ratio and large relative thickness. Aircraft is provided with cabin for crew and payload, fuel tanks, power plant, control members and alighting gear. Lower surface of fuselage is provided with at least one pair of profiled fences. Profiled fences and control members are so arranged that effect of vortex sheet on control members is taken into account. Profiled fences may be mounted movably relative to fuselage. It is good practice to make fences detachable. Profiled fences may be formed by members of lower part of fuselage. EFFECT: improved stability and controllability; full use of lifting properties and maneuverability of aircraft. 4 cl, 3 dwg
