Fortunately, today various free softwarepackages are available to give students a fundamental understanding of the effects of flowregimes on different attributes such as coefficient of lift and drag of airfoils. As part of anintroductory aerospace engineering course, the students at the University of Denver are given aproject to study the NACA 0012 airfoil in the incompressible and compressible flow regimeswith JavaFoil, primarily a vortex panel method with add-on models for viscous and compressibleeffects.

, this level of training is not always sufficient. For universities or businesses vying for lucrative grants,oftentimes these teams may not be considered competitive without having some level of formal education andexperience with UAS/sensor suites. Engineers and scientists may desire to serve as Program Investigators (PI)for grants or as Mission Directors for team flight operations, but often lack practical experience. Likewise,newer UAS pilots may lack requisite technical expertise in UAS/sensor capabilities.In the academic world, students are also looking for ways to gain practical aerospace engineering, remotesensing, and UAS missions experience.
