Airfoil
- Definition & basic design - terms of an airfoil |
Term used for the surfaces of an aircraft that provide lift.
Symmetrical airfoil - equal curvature on the top and bottom surface. Asymmetrical airfoil - different curvature on the bottom of the wing when compared to the top surface. (response 1 of 2) |

|
Relative Wind
|
When a glider flies through undisturbed air, relative wind is the forward velocity and is parallel to and opposite of the direction of flight
Is affected by movement of aircraft through air as well as wind sheer. (response 1 of 1) |
|
|
Angle of Attach
|
Angle formed between the relative wind and the chord line of the wing.
You control angle of attach by changing the "pitch attitude" of the aircraft. (response 1 of 1) |
|
|
Center of Pressure
- Definition - General behavior |
Point on chord line where lift is concentrated. Also called center of lift.
(response 1 of 2) |
|
|
Forces of flight
- Four (4) forces - Considerations regarding glider |
Lift, weight, thrust, drag
(response 1 of 2) |
|
|
Lift
- General behavior of lift when wing in flight - Wing performance with regard to air density |
Lift acts perpendicular to the flight path through the wing's center of lift (center of pressure)
(response 1 of 2) |
|
|
Lifting forces (1 of 4)
- Magnus effect |
Rotating cylinder in airstream. If the top surface is rotating in the direction of the airstream, the local velocity at the surface is higher. On the bottom the velocity is lower. This tends to lower pressure on the top and increase pressure on the bottom of the cylinder
(response 1 of 1) |

|
Lifting forces (2 of 4) - Ventrui effect
- Defined - As it applies to an airfoil |
The Venturi effect is the phenomenon that occurs when a fluid that is flowing through a pipe is forced through a narrow section, resulting in a pressure decrease and a velocity increase.
