The Symphony SA-160 was designed with two unusual vortex generators on its wing to ensure aileron effectiveness through the stall. A vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) [1] or a rotor blade of a wind turbine. [2]
The SA-160 has an aluminum wing design, utilizing a NASA GAW-2 Whitcomb airfoil. To simplify construction the wing has no washout and instead has two composite vortex generators of a unique design, outboard on each wing, to ensure that the inboard portion of the wing stalls first, thus retaining aileron control through the stall.

Vortex Bladeless Ltd. is a Spanish technology startup company that is developing a specific type of wind power generator without rotating blades or lubricants. [1] Power is produced from resonant vibrations when wind passes through the turbine and is deflected into vortices in a process called vortex shedding .
Nose, wing and ventral strakes Vortices over the wing strakes of an F/A-18E Super Hornet. In aviation, a strake is an aerodynamic surface generally mounted on the fuselage of an aircraft to improve the flight characteristics either by controlling the airflow (acting as large vortex generators) or by a simple stabilising effect.
They can be used as an alternative to wing fences, which also restrict airflow along the span of the wing. [1] Vortilons only stream vortices at high angles of attack [8] and produce less drag at higher speeds than wing fences. [9] Pylons used to mount jet engines under the wing produce a similar effect.

The aircraft does not feature any instances of vortex generators, wing fences or many other aerodynamic devices, aside from the integral winglets, which positively contribute to roll stability, drag-reduction, and enhanced aileron effectiveness. The Katana's T-tail configuration has also been claimed to reduce the negative effects of propeller ...

A dogtooth is a small, sharp zig-zag break in the leading edge of a wing. It is usually used on a swept wing, to generate a vortex flow field to prevent separated flow from progressing outboard at high angle of attack. [1] The effect is the same as a wing fence. [2] It can also be used on straight wings in a drooped leading edge arrangement.
