3. I) IN THE BEGINNING… There was no metal There was only wood.
This meant that wings were short.
Short wings need to develop as much lift as possible.

4. II) Wing Designs: A) Straight Leading & Trailing Edges
Straight Leading Edge
Straight Trailing Edge

5. Straight Leading & Trailing Edges

6. B) Tapered Leading & Trailing Edges
Tapered Leading Edge
Once planes were made of metal, the wings could be made longer.
Tapered Trailing Edge

7. Tapered Leading & Trailing Edges

8. C) Sweptback Wings
When planes got even faster, wings were swept back for aerodynamic purposes.

9. Sweptback Wing

10. D) Delta Wings
The fastest of jets use delta wings.

11. DELTA WING

12. III) Frontal Wing Forms
This is the appearance of the wings when looking at them from the front.
The specific design depends on the needs of the aircraft.

13. A) High Wing
High wings allow for greater land view and ground clearance.

15. B) Low Wing
Low wings allow for greater sky visions.

17. C) Mid Wing

19. D) Dihedral Wing
Dihedral wings increase stability against crosswinds.

20. E) Gull Wing and Inverted Gull

21. Focus Point: What are the different Types of Wing Designs?
