The invention provides an annular propeller of a cross-domain aircraft, the cross-domain aircraft and a use method of the cross-domain aircraft, and belongs to the field of cross-domain aircrafts, the connecting part, close to the downstream, of the connecting part of a propeller blade and a propeller hub is a heel part, and the part, from the blade tip to the heel part, of the propeller blade is a rear section; the rear section comprises a spiral section, a straight section and a movable section, one end of the spiral section extends to the blade tip, the other end of the spiral section extends towards the heel part, the straight section is arranged at the heel part and straightly extends by aligning to the free end of the spiral section, one end of the movable section is inserted into the straight section, and the other end of the movable section abuts against the free end of the spiral section; and the movable section moves towards the straight section and is separated from the spiral section. The rear root part of the annular propeller is provided with the movable section, the movable section can move and enter the straight section, the propeller blades are switched between the annular structure and the non-annular structure, the propelling direction of the propeller blades does not need to be changed according to the change of the navigation environment, and the annular propeller can also be applied to a cross-domain navigation unmanned aerial vehicle.

    本发明提出了跨域航行器的环形螺旋桨及跨域航行器及其使用方法,属于跨域航行器领域,桨叶与桨毂相连接的部位靠近下游的连接部位为后根部,桨叶上从叶梢到后根部的部分为后段;后段包括螺旋段、笔直段及活动段,螺旋段一端延伸至叶梢且另一端朝向后根部延伸,笔直段设置在后根部并对准螺旋段的自由端笔直延伸,活动段一端插设在笔直段内且另一端与螺旋段的自由端相抵接,活动段朝向笔直段内移动并与螺旋段脱离接触。本发明的环形螺旋桨后根部具有活动段,活动段能够移动并进入到笔直段内部,通过使桨叶在环形结构与非环形结构之间进行切换,使桨叶无需根据航行环境的改变而改变推进方向,而使环形螺旋桨也能够应用到跨域航行无人机上。
