Design of a UAV with Variable-Span Morphing Wing (original) (raw)

2016

Abstract

Significant interest towards unmanned aerial vehicles (UAV) has developed nowadays. These aircraft systems are designed to carry out certain missions such as surveillance, reconnaissance, and monitoring in civil, military and custom applications. Due to the various requirements and mission constraints, various UAV configurations exist, among which conventional and morphing aircrafts. The latter category refers to aircrafts whose configuration can be altered to achieve certain performance characteristics, namely increased flight range and endurance. This paper discusses the design process and manufacturing of a remote-controlled, experimental UAV for two wing configurations: fixed and variable span, in order to assess the potential benefits of a morphing-wing aircraft. The morphing actuation is projected to be by means of a belt-and-pulley mechanism. The aircraft is intended to transmit live images to a ground station, transmitted from a camera attached underneath the fuselage.
