 Effects of installation angle on the energy performance for photovoltaic cells during airship cruise flightYi Jiang, Mingyun Lv and Kangwen Sun Energy, 2022, vol. 258, issue C Abstract: The installation angle of photovoltaic (PV) cell on airship may affect the received solar radiation on the surface. Cruise is one of the most common flight states of airship, but the investigation about the energy performance with considering installation angle of PV cell during cruise flight is rare. In this paper, an energy model including solar radiation and trajectory planning is established. The flight condition of airship is discussed through numerical simulation. Further, the sensitivity of rotatable angle, elevation angle of PV cell, as well as the sensitivity of two factors to the power output are investigated in detail. The results show that the power output duration time in a day increases with the decreasing of the rotation angle or the elevation angle of PV cell, the PV cell outputs more total energy at smaller installation angle and the ideal installation angle of PV cell is within ±20° when the airship flight in cruise. These results would be helpful for the design of photovoltaic array and improving the power output when airship flights in cruise.
