Phase I Final Report

Eternal Flight

Description
An investigation into a new mission concept approach to achieve unlimited high altitude long endurance flight to achieve geosynchronous atmospheric satellites for civil missions.  The study will compare the new approach to existing approaches, with detailed analysis of the key differences that enable a reduction in structural weight by 50%, while also decreasing the drag by 50% through significantly higher aspect ratio wings, higher wing loading, and lower payload drag.
