Astonishingly large fairings, which blend thick, blunted leading edge, wing and fuselage creating an aerodynamic continuum, are one of design key features.
By eliminating acute angles and producing lift, this organic shape reduces
both drag due to wing-fuselage interference effects and drag due to the gap in the lift distribution across the span at the fuselage.
This means that KATANA is designed to be efficient at high angles of attack a
condition in which an aerobatic aircraft spends much of its flying time.
