Create vortex's lmfao

The vortex generator transports energy into the boundary layer from the outer flow, and is used mainly for control of already separated flow rather than for the prevention of separation on wings, diffusers, or bends in channels at subsonic and supersonic speeds.

@margssweetie ah that old concept. Still destroys decals tho 😉
