Periodic Energy-Optimal Path Planning for Solar-Powered Aircraft

Abstract: This paper considers energy-optimal path planning in a loitering mission for solar-powered unmanned aerial vehicles (UAVs) which collect solar energy from the sun to power their flight. We consider ascending and descending flight maneuvers in a periodic mission constrained to the surface of a vertical cylinder. The coupling of the aircraft kinematic and energetic models is treated in a novel scheme that implements both the periodic and cylindrical constraints. Optimum trajectories are identified by specifying … Show more

“…The position of the sun plays an important role in the amount of energy collected. This model is more formally presented in [15]. If a and e are the azimuth and elevation angles of the sun respectively, then the input φ , the bank angle of the aircraft, is related to the incidence angle i as…”

“…The sun position is however assumed constant. Spangelo [37] investigates optimal climb and descent maneuvers during loitering. Hosseini [20] adds sun-position time dependence, but assumes perfect clear-sky conditions instead of considering meteorological data.…”
