Dogtooth Extension
A dogtooth is a small, sharp zig-zag double kink in the leading edge of a wing. On a swept wing, it is used is to generate a vortex of air flowing backwards over the wing, reducing spanwise airflow.
Where the dogtooth is added as an afterthought as for example with the Hawker Hunter and some variants of the Quest Kodiak, the dogtooth is created by adding an extension to the outer span only of the leading edge.

Famous quotes containing the word extension:
“We know then the existence and nature of the finite, because we also are finite and have extension. We know the existence of the infinite and are ignorant of its nature, because it has extension like us, but not limits like us. But we know neither the existence nor the nature of God, because he has neither extension nor limits.”
—Blaise Pascal (1623–1662)
