In aerodynamics, the taper ratio (often represented as “λ” or “TR”) is a geometric parameter used to describe the shape of a wing, specifically a wing’s planform. The taper ratio is defined as the ratio of the tip chord (“ct”) to the root chord (“cr”) of a wing.
- “ct” is the tip chord (width) of the wing.
- “cr” is the root chord (width) of the wing.
