未来的无人机将向远程,高空方向发展,以提高自身的生存能力,对指定目标实施不间断的跟踪监视.为了在高空长时间工作,除了要求飞机的气动性能好外,轻巧、省油、大功率的发动机是必不可少的. 二冲程活塞式汽油发动机有体积小、重量轻,升功率大,操作简单等优点,而成为超轻型飞机尤其无人机的动力装置。二冲程的比四冲程的发动机重量轻、升功率大、操作简单,燃烧频率也高1倍,因此旋
The future of UAV will be long-range, high-altitude direction in order to improve their viability, the designated target implementation of uninterrupted tracking surveillance.In order to work at high altitude for a long time, in addition to requiring the aircraft’s aerodynamic performance, light, fuel-efficient, High-power engine is essential.Euro-stroke two-stroke piston engine has the advantages of small size, light weight, high power, simple operation, etc., and become the UAV aircraft especially UAV power plant. Two-stroke four-stroke engine than the light weight, high power, simple operation, the combustion frequency is also high 1 times, so spin
