Abstract:
Conventional fossil fuel powered unmanned aircraft systems (UAS) has limited flight range which totally depends on the fuel it carries. Too much fuel on board is not possible for the airplane application due to weight limitation. In addition, fossil fuels produce emissions and pollutants. The most favourable candidate energy source to power the UAS is solar energy. With the PV panel and energy storage devices, the UAS can get enough energy for very long range flights and high enough power for the auxiliary electrical loads. This paper presents a hybrid energy storage system which is composed of PV panel, rechargeable fuel cell and rechargeable battery to solve the energy issues of long endurance UAS. Finally, the MATLAB/SIMULINK model of each component is constructed and the simulation results are shown.
