摘要
小功率航空活塞发动机是微型无人机系统的主要动力型式,单一燃料的重油使用是未来无人机动力系统发展的必然趋势。结合国内外无人机发展趋势和动力系统型式选择,分析了小功率航空重油活塞发动机的应用需求特点;根据航空燃料发展的单一化趋势,指出了小功率航空活塞发动机采用重油的发展趋势和面临的技术瓶颈;整理了现阶段国内外在小功率航空重油技术方面的不同创新思路和实现型式,分析评估了不同技术路线的应用特点和技术难度。
Small aero-piston engines are the most common power source for micro scale UAV （Unmanned Aerial Vehicle）,and single heavy fuel supply is the future technology development trends. Based on the development of modern small aero-piston engine application in small UAV systems and different power plant options,small aero-piston engine technology requirements are explained;according to the single fuel supply development trends,technology difficulties on heavy fuel application are presented;different innovations and engineering implementations for heavy fuel supply and injection are introduced and analyzed.
