Detailed Technology Description

Researchers at Nagoya University invented a novel vortex generator, Smart Vortex Generator (SVG). SVG is composed of shape memory alloy and changes its shape automatically depending on air ambient temperature, without any energy supply and mechanical/electrical controls. Shape memory function enables SVG to transform its shape between a vortex generating position at the ground temperature and a drag reducing position at the cruise altitude temperature. When the difference between the temperature at takeoff/landing and at steady cruise reaches around 130 degrees Fahrenheit, SVG transforms its shape for vortex generation/drag reduction.
