This paper deals with modelling the performance of an air transport network operated by existing subsonic and the prospective supersonic commercial aircraft. Analytical models of indicators of the infrastructural, technical/technological, operational, economic, environmental, and social performance of the network relevant for the main actors/stakeholders involved are developed. The models are applied to the given long-haul air route network exclusively operated by subsonic and supersonic aircraft according to the specified “what-if” scenarios.The results from application of the models indicate that supersonic flights powered by LH2 (Liquid Hydrogen) could be more feasible than their subsonic counterparts powered by Jet A fuel, in terms of about three times higher technical productivity, 46% smaller size of the required fleet given the frequency of a single flight per day, 20% lower sum of the aircraft/airline operational, air passenger time, and considered external costs, up to two times higher overall social-economic feasibility, and 94% greater savings in contribution to global warming and climate change. These flights could be less feasible in terms of about 70-85% higher aircraft/airline operational costs, 70% and 19% higher fuel consumption and emissions of Green House Gases, respectively, and 6-13% higher noise compared to the specified acceptable levels.

亚音速和超音速飞机运营的航空运输网络的建模性能

本文涉及对现有亚音速和未来超音速商用飞机运营的航空运输网络的性能进行建模。开发了与主要参与者/利益相关者相关的网络的基础设施、技术/技术、运营、经济、环境和社会绩效指标的分析模型。将模型应用于特定的由亚音速和超音速飞机根据指定的“假设”场景运营的给定长途航线网络。模型应用结果表明，由 LH 提供动力的超音速飞行2（液氢）可能比由 Jet A 燃料驱动的亚音速同类产品更可行，技术生产率提高约三倍，考虑到每天单次飞行的频率，所需机队规模缩小 46%，总和降低 20%飞机/航空公司的运营、航空乘客时间和考虑的外部成本，总体社会经济可行性提高了两倍，对全球变暖和气候变化的贡献节省了 94%。这些航班可能不太可行，因为飞机/航空公司的运营成本高出 70-85%，燃料消耗和温室气体排放分别高出 70% 和 19%，噪音比规定的可接受的高出 6-13%水平。
