Taxiing configuration analysis and test platform of hybrid propulsion systems

This study investigates the optimal hybrid propulsion system configuration for taxi operation of light electric aircraft considering current technological advancements. System designs are developed based on the specifications of contemporary components such as energy storage systems, generators, and electric motors. Configuration analyses are conducted for the designed systems using a test platform created in MATLAB Simulink, evaluating parameters such as system efficiency, weight, hybridization ratio, fuel consumption, and emissions. A failure analysis is performed to compare system reliability and assess the impact of each component's failure on the aircraft's mission profile. Based on the analysis results and information gathered from the literature, a SWOT analysis is conducted to compare the strengths, weaknesses, opportunities, and threats of each configuration. The hybridization analysis of taxi operation using state of the art components concludes that the parallel hybrid propulsion system is more efficient, reliable, and feasible compared to the series hybrid propulsion system. Due to the negative impact of the series hybrid system on internal combustion engine conversion efficiency, weight, safety, cost, and ergonomics, the parallel hybrid system is expected to be more preferable for the hybridization of an existing aircraft design.
