摘要
传统飞机的辅助动力装置噪声大、碳排放量大、效率低,已无法满足多电/全电飞机的发展要求。而燃料电池具有高能量密度、零排放、使用寿命长、低噪声和高效率等优势。本文建立了燃料电池模型并进行优化,以更好地体现其稳态和瞬态性能。建立了由燃料电池和超级电容组成的混合系统作为飞机辅助能源单元的模型,验证了其电能质量满足GJB181A-2003标准,并与传统辅助动力装置进行对比,显示其在响应速度、效率以及功重比上具有明显优势。
The traditional auxiliary power system with some disadvantages such as wide noise, huge carbon emission and low efficiency, cannot meet the requirement of more/full electric aircraft. However, with the development of the technological level, fuel cells with many advantages such as high energy density, zeroemission, long service life, less noise and high efficiency come to the horizon. This paper modeled the renewable energy device （fuel cell） and optimized it to characterize the performance. And then, modeling the hybrid auxiliary power system with fuel cell/supercapacitor, and comply with the aircraft standard of GJB 181A-2003. Comparing with the traditional APU, the fuel cell system dominates the response speed, efficiency and power to weight ratio.
