氢涡扇客机概念方案的综合分析与优化
Comprehensive analysis and optimization for conceptual scheme of hydrogen-powered turbofan aircraft
摘要
Abstract
Hydrogen-powered turbofan aircraft is powered by the direct combustion of hydrogen in the turbofan en-gine,which is an important development direction of green aviation.Aiming at the concept design of hydrogen-powered turbofan aircraft,a comprehensive analysis and optimization method is studied.According to the character-istics of hydrogen-powered turbofan aircraft,the liquid hydrogen system model is established based on physical principles,and the discipline analysis methods of conventional aircraft are updated and expanded.A multidisci-plinary analysis method is developed,which consists of engine,liquid hydrogen system,geometry,weight,aero-dynamic,performance,emission and cost modules.Based on the multidisciplinary analysis method,the primary pa-rameters of the 150-seat hydrogen turbofan aircraft concept are optimized,and the effects of the parameters of the liquid hydrogen tank on the aircraft weight and cost are investigated.The results show that the operating empty weight of the optimized aircraft is reduced by 1.63%and the direct operating cost is reduced by 1.79%.The shape of the liquid hydrogen storage tank and the characteristics of the insulation material have significant impacts on the aircraft weight and direct operating cost.The method presented in this paper can be effectively applied to the con-ceptual design of hydrogen-powered turbofan aircraft.关键词
