The invention discloses an engine and an unmanned aerial vehicle, the engine comprises a cylinder body, a combustion chamber with a lower opening, a piston mounted in the combustion chamber and capable of sliding back and forth along the axis of the combustion chamber; the crankcase is fixedly connected with the bottom of the cylinder body, and a crankshaft cavity communicated with the combustion cavity is formed in the crankcase; the crankshaft is mounted in the crankshaft cavity, is in transmission connection with the piston through a connecting rod and can be driven by the piston to rotate along the axis of the crankshaft; the output shaft is in transmission connection with the crankshaft and can rotate along the axis of the output shaft; the axis of the output shaft is parallel to or coincides with the axis of the combustion cavity. The axis of the output shaft is parallel to or coincides with the axis of the combustion cavity, so that the whole engine is formed by arranging all parts along the axis, an axial flow linear structure is integrally formed, wind resistance is reduced, light weight of the unmanned aerial vehicle is achieved, and flexibility is improved.

    本发明公开了一种发动机及无人机,一种发动机包括:缸体,具有下部开口的燃烧腔,所述燃烧腔内安装有一活塞,所述活塞能沿燃烧腔的轴线往复滑动;曲轴箱,与缸体底部固定相连,内设有与燃烧腔连通的曲轴腔;曲轴,安装于曲轴腔,通过连杆与活塞传动相连,以能在活塞的带动下沿自身轴线旋转活动;输出轴,与曲轴传动相连,以能沿自身轴线转动;所述输出轴的轴线与燃烧腔的轴线平行或重合。本发明通过将所述输出轴的轴线与燃烧腔的轴线平行或重合,使得发动机的整体是沿一轴线布置各个部件,整体形成一个轴流线性的结构,减少了风阻,实现了无人机的轻量化并提高了灵活性。
