Flight Testing of Dynamic Soaring Part-2 : Open-Field Inclined Circle Trajectory

Résumé

This paper presents the second part of flight experiments for a known dynamic soaring trajectory; open-field inclined circle trajectory. Energy extraction through dynamic soaring can improve the range and endurance performance of fixed-wing vehicles on certain missions such as ocean monitoring, or flying over orographic wind sources. However, fundamental challenges are making the dynamic soaring difficult to apply, such as simultaneous exploration and exploitation of the dynamic wind field, estimation of the total energy state, high-level optimum path planning, guidance for trajectory tracking, and finally the low-level attitude control. Real-life application of dynamic soaring presents even more additional challenges such as poor and limited sensor measurements, limited computation, disturbing atmosphere, and estimation of the dynamic wind field. In this study, we assess the feasibility of dynamic soaring in open-field inclined circle trajectory with a small autonomous glider to show the positive power contributing segments during the flight. Moreover, it is observed that the inclined circle trajectory can be flown more energy efficient than flat ones in the presence of wind. Several representative cases have been analyzed, quantifying the ratio between power values for invested, required, and harvested.
