Optimal Design of a High-altitude Solar-Powered Unmanned Airplane

Abstract

This paper describes a multi-disciplinary design and optimization framework tailored for the conceptual development of high-altitude solar-powered unmanned aerial vehicles. The aircraft baseline configuration that the framework is able to handle is very similar to that of Zephyr, which is developed by the UK based company QinetiQ. The disciplines of aerodynamics, structures, stability, weight, and systems were considered and integrated into a modeFrontier workflow, capable of providing a relatively simple sizing, but highly realistic airplane.
