摘　　要：小型二冲程航空活塞发动机是微型无人机动力系统的主要动力装置,结合燃油一体化要求下重油燃料的使用,对国内外小型二冲程重油航空发动机的研究现状和技术方案进行优劣势分析,提出未来主要技术发展方向以及难点和创新技术,希望对我国二冲程重油发动机的研究起到借鉴作用。The small two-stroke aero-piston engine is the main power source of the micro-UAV(Unmanned Aerial Vehicle). Based on the use of heavy fuel under the requirements of fuel integration,this article analyzes the research status and technical strengths and weaknesses of small two-stroke heavy fuel aero engines at home and abroad. The main technical development direction in the future,as well as the difficulties and innovative technologies are presented,and hope that it can be used as a reference for the research of two-stroke heavy fuel aero engines in China.
