摘要
新一代飞机迫切需要研究的核心技术之一是航空能源转型技术,而降低飞机碳排放的有效途径是发展氢能源动力飞机.本文分析了氢能飞机的推进技术和储存技术,构建了氢能飞机改型设计优化方法,针对某通航飞机利用该方法对不同的能源方案进行了计算和优化,验证了不同能源动力方案的可行性.进一步对不同的动力装置组合进行了优化对比分析,分析了不同发动机方案带来的重量收益,并给出了不同起飞重量的飞机采用不同能源动力系统的重量,以期为不同类型和用途的飞机选取能源动力方案提供参考.
Abstract
Aviation energy transformation technology is one of the core technologies that the new generation of aircraft urgently needs to study.The development of hydrogen aircraft is an effective way to reduce carbon emissions.This paper first analyzes the propulsion technology and storage technology of the hydrogen aircraft.Then the optimization method of the modified design of the hydrogen aircraft is constructed,which is used to calculate and optimize different energy schemes,and verifies the feasibility of different energy power schemes.Further different power plant combinations are optimized and compared,and the weight benefits of different engine schemes are analyzed.The weights of different energy power systems used by aircraft with different takeoff weights are given.It is expected to provide reference for selecting energy and power schemes for different types and uses of aircraft.
