Question

Is plan forms with smooth edge shapes?

(a) True

(b) False

This question was posed to me during a job interview.

My question comes from The Lifting Surface Theory topic in section Flow over Airfoils over Finite Wing of Aerodynamics

Answer 1

Correct option is (a) True

To elaborate: Plane forms with smooth edge shapes with finite tip chord, suitable loading modes are readily defined of the leading and trailing edge respectively and the wing semi span then to ensure that the downwash modes are regular.
