(a) A swept wing with an aspect ratio of 8 and half-chord line sweep of 25° must be modified. The new suggested design has an aspect ratio of 4 and half-chord line sweep of 50°. Note that a, for the original wing is 0.12/degree and for the new design is 0.16/degree. Which design is better and why? (b) Compare the new swept-wing design of Part (a) with a straight wing of same properties as this swept wing. Determine which wing is a better choice and justify your answer.
