Question 2 1 2.6 An aircraft has a total mass (m) of 2200 kg. The planform area (S) of the wings is 26.4 m² with a wingspan (2 xs) of 14.5 m. The wings are straight-tapered with a taper ratio (1) of and with a width at their root (centreline) chord equal to co. The quarter-chord is swept back at 22.5°. a) Show that the planform area (S) of wings is given by S = Co (1+1)s and calculate the root chord (co). b) What will be the change in the Aspect Ratio (AR) if the planform area (S) is kept the same whilst the wingspan (2 x s) is increased by 10%?
