Effect of flight level to maximum power utilization for PEMFC/supercapacitor hybrid uav with switched reluctance motor thruster

Eyyup Oksuztepe et al.

Summary: In this study, the performance of a fixed-wing PEMFC/SC hybrid UAV with an SRM thruster was investigated at different flight levels. The negative impact of flight levels on the PEMFC was analyzed due to changing ambient conditions. A derived international standard atmosphere (ISA) model was used to predict PEMFC voltage-current-power ratings at 100 m intervals for altitudes up to 7500 m. The study confirmed the effectiveness of utilizing a maximum power point tracking (MPPT) model to prevent overshooting the maximum power level and the use of SC as an auxiliary power source.
