Construct an airfoil.

Construction should include

• following the engineering design process
• adhering to specifications and constraints
• creating internal and external structures
• using multiple fabrication techniques where appropriate
• adjusting.

Process/Skill Questions:

• Why is it necessary to balance the airfoil?
• What effect would using different materials have on an airfoil?
• What conditions support the use of a particular fabrication technique?
• How are wings and propellers similar and different?
