If the angle of attack is to be 3 degrees Determine how large zo/c should be in order for this airfoil to produce 50% more lift than a symmetric airfoil would at the same angle of attack. These assumptions include an infinitely thin airfoil, small camber, and small angles of attack. Thin airfoil theory as studied in the class provides a simple means of calculating the lift coefficient for an airfoil, provided several assumptions are satisfied. Do you think 200% more lift is realistic by making zo/c larger yet, and why? If the angle of attack is to be 3 degrees Determine how large zo/c should be in order for this airfoil to produce 50% more lift than a symmetric airfoil would at the same angle of attack. (d) Consider a thin airfoil with the camber line profile (b) In the theory development there is an expressionĬan you explain what is the physical meaning of w', what is x, what is, and how are the two minus signs on the right consistent with our knowledge of the properties of a vortex sheet placed along the chord line? (c) Make an annotated sketch that compares the lift curves of symmetric and cam- bered airfoils. (a) Make a list of the key assumptions as you know them. SOLVED: Thin airfoil theory as studied in the class provides a simple means of calculating the lift coefficient for an airfoil, provided several assumptions are satisfied.
