NettetQuestion: Q 2) A proposal for a new aircraft design has a linearly tapered wing of aspect ratio R=6 with taper ratio 5 (ratio of root chord to tip chord). To reduce manufacturing cost the wing is to be untwisted and have the same aerofoil section along the span; the 2-D stall angle of the aerofoil profile is 15º and the lift curve slope is 27 per radian. Nettetwing about an aerodynamic center, and the angle of zero lift. Because of the importance of span load distribution, numerous methods for computing it have been proposed but, since they are generally lengthy and complicated, they have been little used in practice. In reference 1 the span loading was given for linearly tapered wings with rounded tips.
