摘要:

氢燃料电池混合动力客机是未来降低航空业碳排放的可行技术路线之一。然而目前针对不同氢燃料电池混合动力技术对飞机整体特性影响的机理分析和定量趋势研究较少。针对该问题,建立了氢燃料电池混合动力客机关键参数敏感性分析方法,定量研究了关键技术参数变化对飞机整体特性的影响和作用趋势。同时,根据当前至未来10年内各阶段氢能技术发展所能达到的不同技术水平,给出匹配不同阶段的最佳动力分配策略。以窄体干线客机为研究对象,开展关键参数敏感性分析。结果表明,氢燃料电池功率密度对飞机的最大起飞质量和使用空重影响最大,而巡航时的氢动力配比对飞机的碳排放量以及燃料和碳税成本影响最大。在不同技术水平下,提高巡航时的氢燃料电池提供的推力占比整体而言可以降低飞机的最大起飞质量以及燃料和碳税成本,但起飞时氢动力占比不能过大。在未来混合动力技术预期发展过程中,当巡航时氢燃料电池提供的推力占比取0.4、起飞时氢燃料电池提供的推力占比取0.15时,飞机可获得最轻的最大起飞质量和最低的燃料和碳税成本。相比于传统飞机,氢燃料电池混合动力客机在未来10年将降低燃料和碳税成本达15%~26%。

Abstract:

Hybrid hydrogen fuel cell aircraft is one of the feasible technological routes to reduce carbon emissions in the aviation industry. However, there is a lack of mechanism analysis and quantitative trend research on the impact of different hybrid hydrogen fuel cell technologies on the overall characteristics of aircraft. A sensitivity analysis method for key parameters of hybrid hydrogen fuel cell commercial aircraft is established to study the mechanism and impact trend of key technical parameters on the overall characteristics of the aircraft. Optimal power allocation strategies matching different technological development stages from current to future 10-year are proposed based on projected hydrogen energy developments. Focusing on narrow-body commercial aircraft, sensitivity analysis on key parameters are conducted. The results show that the power density of the hydrogen fuel cell has the greatest impact on the maximum takeoff weight and operating empty weight of the aircraft, while the thrust proportion by hydrogen fuel cell during cruising has the greatest impact on the carbon emissions of the aircraft, as well as the fuel and carbon tax costs. At different technical levels, improving the thrust proportion by hydrogen fuel cell during cruising can generally reduce the maximum takeoff weight and fuel and carbon tax costs of the aircraft, though excessive hydrogen power allocation during takeoff should be avoided. Under anticipated hybrid technology development trajectories, the aircraft can obtain the lightest maximum takeoff weight and the lowest fuel and carbon tax costs when the thrust proportion by hydrogen fuel cell during cruising is 0.4 and the thrust proportion by hydrogen fuel cell during takeoff is 0.15. Compared with the traditional aircraft, the hybrid hydrogen fuel cell commercial aircraft can reduce fuel and carbon tax costs by 15%–26% in the next decade.
