초록

A controllable vortex generator for reducing aerodynamic drag when vortex generation is not desired. The vortex generator includes a fin having a fixed forward portion and an aft portion which is movable between deflected and undeflected positions. At least a portion of the fin is formed of a memory shape alloy. The fin is attached to a base mountable to a surface such as the wing skin of an aircraft. An electrical resistance heating element is bonded to the fin and a controllable source of electric power is connected to the element. When the fin is heat...
