Chapter 10: Designing a Wing

Question 1

Ideal Wing Criteria (2)

Answer 1

High aspect ratio

elliptical lift distribution (0 deltaP @ tip, max @ root)

Question 2

High Aspect Ratio Disadvantage

Answer 2

Wing strike
Construction issues
High speed flight
Aerodynamic damping

Question 3

4 Basic Wing Designs

Answer 3

Elliptical -> Cl constant -> most efficient
Rectangular -> Cl low at tip -> root stall
Straight tapered -> Cl high at mid -> mid stall
Sweepback taper -> Cl high at tip -> tip stall

Question 4

Wing Loading

Effect on vortices

Answer 4

W / S
Commercial -> low wing loading
High wing loading = higher delta P = greater vortices
