A Literature Review on UAVs in Low Pressure Atmospheres

Abstract

Over the years, there has been a rapid development of UAVs, but there is still limited research on their function in low pressure/high altitude systems. This is mostly because of limited access to low pressure testing environments, technological constraints, and high research and development costs. However, UAVs in low pressure environments can be extremely beneficial for space exploration and even search-and-rescue missions on high peaks like Mount Everest. In such environments, reduced air density makes it difficult for UAVs to maintain lift. [1] Specially designed UAVs, however, could provide aerial support as well as payload delivery. To facilitate the design of UAVs capable of flying in low pressure environments, this paper investigates previous related missions and lays the groundwork for dynamics and control of these unique vehicles.
