A new vortex generator (VG) concept is proposed, where VGs are effective during take-off and landing and stowed during cruise by utilizing a function of shape memory alloys (SMAs) and difference in temperature between a cruise altitude and a ground. This new VG is named Smart Vortex Generator (SVG). Numerical simulation using a simplified mathematical model of SVG indicates that temperature of SVG can follow an ambient temperature change during descending/ ascending and SVG can change its shape between a stowed position and a vortex-generating position. Moreover, a conceptual demonstration model of SVG is made of SMA ribbons and ribbon springs. This demonstration model verifies that SVG can be practically transformed between the two positions by cooling and heating. Vortex generators are devices to delay or prevent flow separation by generating vortexes and mixing flow. They are usually solid vanes and fixed on surfaces of vehicles, turbomachines, etc. For some airplanes' wings VGs are necessitated during take-off and landing, when the wings have a high angle of attack and a large camber. However, they have an adverse effect during cruise because of their useless drag.
