飞机可持续滑行技术理论进展与应用挑战

The main types and technical pathways of sustainable aircraft taxiing technologies were outlined. By focusing on single-engine taxiing, dispatch towing taxiing, and onboard system taxiing, the operating principles, operational procedures, and key control points of different taxiing technologies were clarified. Theoretical research progress on sustainable taxiing technologies was reviewed, including environmental performance modelling and evaluation, physical characteristic analysis, and system design. The fuel consumption and pollutant emission measurement methods of different taxiing technologies during the taxiing phase were extracted. Based on engineering practices at Chinese and international airports and airlines, the current application status of sustainable taxiing technologies was discussed, and differences among technologies in terms of operational efficiency, equipment compatibility, and operational complexity were discussed. On this basis, the limitations and applicability conditions of existing sustainable taxiing technologies were comprehensively evaluated from the perspectives of technical performance, cost effectiveness, operational safety, and applicable scenarios. The promotion and application of relevant technologies were summarized in the context of civil aviation operations in China. The results show that sustainable taxiing technologies have significant potential to reduce fuel consumption, carbon emissions, and noise pollution during the aircraft taxiing phase. Clear differences exist among technologies in terms of energy-saving and emission reduction effects, as well as operational characteristics. Single-engine taxiing shows advantages of low implementation cost and relatively mature operating procedures, and it is suitable for promotion within existing operational systems. Dispatch towing taxiing and onboard system taxiing further reduce the operating time of main engines and achieve more pronounced energy-saving and emission reduction effects, but they impose higher requirements on equipment conditions and operational organization. Overall, large-scale application of sustainable taxiing technologies remains constrained by technical maturity, economic feasibility, operational management complexity, and regulatory certification. The technologies should be promoted through technology-specific pilot implementation and standard development in accordance with airport operating environments and aircraft fleet structures.
