 ## Introduction
-The OpenUAS Design team utilizes SolidWorks to model the UAV designs. The team has created 3 versions: OpenUAS 1.0, 2.0, 3.0, and 5.0 (under-development) which can be looked at in more detail on the left side of your screen. The Design team is also implementing computational fluid dynamics (CFD), using StarCCM+, in their considerations with modifying designs prior to and following flight tests. This allows the team to look at pressure data, for example, to modify existing parts before flight.
