Abstract
Folding wingtip (FWT) devices not only enable aircraft incorporating high aspect ratio wings to fit into airport gates, but also can be used as a load alleviation device by allowing the hinge to be released in-flight, known as semi-aeroelastic hinge (SAH). This study establishes a preliminary design framework for wings incorporating such devices, and implements a sizing process to investigate the impact of the device on the wing weight and aircraft range. For the cases considered, it is shown that a 40% reduction in wing weight can be achieved by implementing a SAH device onto a high aspect ratio wing, leading to a 9% improvement in aircraft range.
