摘要
在分析国内外航空重油活塞发动机发展现状的基础上,对现有成熟机型进行对比分析,获得了不同功率级别航空重油活塞发动机的核心技术指标,提出我国发展航空活塞发动机重油化和国产化的重要意义.按照功率级别分析了航空重油活塞发动机发展的技术途径,总结了高功质比航空重油活塞发动机面临的技术难点,提出了点燃式航空重油活塞发动机的关键技术,即重油燃料的快速雾化技术、快速冷起动技术、爆震抑制技术以及高空增压功率恢复技术,突破以上关键技术将对航空重油活塞发动机技术的发展具有重要意义.
Abstract
Based on the analysis of the development status of aviation heavy fuel piston engines at home and abroad,the core technical indexes of engines with different power levels were obtained by comparing and analyzing the existing mature models,and the important significance of developing aviation heavy fuel piston engines in China was put forward.According to the power level,the technical path of the development of aviation heavy fuel piston engine was analyzed,the technical difficulties faced by the heavy fuel engine with high power-to-weight ratio were summarized,and the key technologies of the spark-ignition aviation heavy fuel piston engine,namely,the rapid atomization technology,the rapid cold start technology,the knock suppression technology and the high-altitude supercharging power recovery technology of heavy fuel,were presented.A breakthrough over the above key technologies will be of great significance to the development of aviation heavy fuel piston engine technology.
