Currently, wide area coverage with manned aircraft, or existing UAS, requires expensive logistical operations and many flight sorties, which are made especially difficult if operating from remote airfields in inhospitable climates. There is currently a need for a low-altitude long endurance unmanned aircraft that can provide the expansive coverage necessary for cryospheric investigations. Extreme cold places unique requirements on aircraft if they are to operate consistently and reliably in these environments. This Phase I SBIR will, through design, analysis and test activities, determine the feasibility and system impact of making a low altitude ultra-long endurance UAS compliant with varying levels of minimum temperature requirements.
