Prediction Model Validation for Circular Flight Paths for CREATeV

This study focused on the analysis of flight test data collected during an 18-hour flight for CREATeV. CREATeV is an unmanned solar Clean Renewable Energy Aerial Test Vehicle that aims to achieve complete ultra-long endurance flight using 96 wing-mounted solar cells. Flight test data were extracted to understand the aircraft’s power collection and usage. A prediction model was validated by considering wind effects and position of the sun throughout a selected flight segment. The model was validated through methods discussed in this study. The validated prediction model can be applied to any circular flight to predict the power required for banking turn, solar power collected, battery charging power, aircraft bank angle and heading. A theoretical flight scenario was inputted into the validation model to demonstrate how the model may be used.
