Abstract

Developing high-efficiency and low-carbon propulsion systems is a pressing concern within the aviation field. This paper studies a hybrid power system that combines a solid oxide fuel cell and a gas turbine (SOFC-GT) with propane as fuel, which is easy to store and has a high energy density. The analysis focuses on key parameters such as compressor pressure ratio, fuel utilization rate, and fuel distribution. And a balance between system efficiency and the power-to-weight ratio has been achieved through multi-objective optimization. The conclusions indicate that system efficiency and system weight in the hybrid power system are optimized in opposite directions. Within the design parameters, the hybrid power system’s efficiency achieves 0.621, the specific fuel consumption is 115.2 g/kWh, and the power-to-weight ratio is 0.569 kW/kg. Further discussion on the application of this hybrid system in long-endurance unmanned aerial vehicles shows an efficiency of 0.651 during the cruise phase, indicating a promising application prospect of a propane-fueled SOFC-GT hybrid system in the aviation field.

航空应用 SOFC-GT 混合动力系统的优化设计

开发高效、低碳的推进系统是航空领域亟待解决的问题。本文研究了一种混合动力系统，该系统结合了固体氧化物燃料电池和燃气轮机（SOFC-GT），以丙烷为燃料，丙烷易于储存且能量密度高。分析的重点是压缩机压力比、燃料利用率和燃料分配等关键参数。通过多目标优化，实现了系统效率和功率重量比之间的平衡。结论表明，混合动力系统的系统效率和系统重量的优化方向相反。在设计参数范围内，混合动力系统的效率达到 0.621，比油耗为 115.2 g/kWh，功率重量比为 0.569 kW/kg。关于该混合动力系统在长航时无人飞行器中应用的进一步讨论显示，巡航阶段的效率为 0.651，这表明以丙烷为燃料的 SOFC-GT 混合动力系统在航空领域具有广阔的应用前景。
