Why Fighter Jets Have 'Sawtooth' Wings #Shorts

Added: 2026-05-27

[00:00:00]Ever notice those jagged sawtooth notches on high-performance fighter jet wings?

[00:00:04]They aren't there for style.

[00:00:06]Those notches, known as dogtooth extensions, serve a critical aerodynamic purpose.

[00:00:12]At high angles of attack, air tends to flow spanwise toward the wing tips, which can lead to a dangerous stall.

[00:00:18]That sharp sawtooth creates a powerful vortex that re-energizes the airflow over the outer portion of the wing.

[00:00:24]This keeps the aircraft stable and responsive, even during aggressive maneuvers that would make a standard wing lose all lift.

[00:00:31]It's a simple, elegant piece of engineering that keeps pilots in control when the physics of flight gets extreme.

[00:00:36]Ever wonder what other hidden shapes on aircraft do?
