Curved Wing in Airflow
Open to everyone until Friday, October 2
To keep it, print it while it is open.
A wing’s upper surface curves upward. Air moves faster over that curve than beneath, so the pressure above drops and the wing is pushed upward.
In the picture
- The curved upper surface: the arched edge where air travels a longer path.
- A tightly spaced streamline above the wing: fast-moving air at lower pressure.
- The lower surface: the underside where air moves more slowly and pressure is higher.
- The larger upward arrow: the net upward force on the wing.
Examples
- A paper airplane glides farther when air flows over its curved wings.
- An airplane rises from the runway as air moves over its wings.
Key takeaways
- Faster air over a curved surface has lower pressure.
- Higher pressure below a wing pushes it upward.
