MULTI-PURPOSE FIGHTER Russian patent published in 2001 - IPC

FIELD: aviation. SUBSTANCE: center-wing section of fighter is made in plan in form of lifting disk with leading and trailing edges over its generatrix. Lifting disk is provided with control aerodynamic surface in form of nose segments of lifting disk of center-wing plane with leading edge over generatrix circle of lifting disk located on either side of fuselage. Nose segments are swivel relative to their axes coinciding in its extension in plan with leading edge of adjoining swivel outer wing panel. Axis of turn of deflectable leading edge of each swivel outer wing panel and axis of turn of nose segment of lifting disk of center-wing section adjoining it are parallel in plan. Point of application of total position or negative lift force of aircraft at deflection of swivel panels is brought close to point of aerodynamic center of aircraft ensuring control of fighter with no change in its longitudinal moment in lift force control system. EFFECT: improved maneuvering characteristics; reduced landing run. 3 dwg
