Title: (Optional) Explain how relative wind, angle of attack, center of lift, and laminar flow affect the performance of an airfoil.
Course: Aviation Maintenance Technology I (20114-I) > Section: Exploring Airframe and Control Surfaces

Explanation should include definitions of

- relative wind—the direction of movement of the atmosphere relative to an aircraft or an airfoil
- angle of attack—the angle between a reference line on a lifting body (often the chord line of an airfoil) and the vector representing the relative motion between the lifting body and the fluid (air) through which it is moving
- center of lift—the point at which the pitching moment coefficient for the airfoil does not vary with lift coefficient (i.e., angle of attack)
- laminar flow—a flow regime characterized by high momentum diffusion and low momentum convection; the opposite of turbulent flow (laminar flow is smooth, while turbulent flow is rough).

Process/Skill Questions:

- What is relative wind?
- What is significance of laminar flow vs. turbulent flow?
