The invention provides a deployable annular propeller and a cross-domain aircraft, and belongs to the field of annular propellers, the deployable annular propeller comprises a propeller hub, blades and a locking part, the blades are made of flexible materials, the blades are bent and deformed into a first form or rebound and reset into a second form, one end of each blade is fixedly connected with the peripheral wall of the propeller hub and is set as a root part, and the other end of each blade is set as a locking part; the other end of the paddle is a free end and is arranged as a tip part; the paddle is in a first form and is bent into a ring shape, and the tip part is connected with the locking part; and the locking part releases the tip part, and the paddle is switched to the second state. The annular propeller blades are made of the flexible materials and can elastically deform, the propeller blades are bent to be annular, the tip parts of the propeller blades are fixed to the locking parts, and the formed annular propeller is more suitable for the underwater navigation scene of a cross-domain aircraft; and when the tip parts of the paddles are separated from the control of the locking parts, the paddles are reset and deformed into non-annular propellers, so that the propeller is more suitable for the scene that the cross-domain aircraft sails in the air, and the paddles have the capability of switching from an annular structure to a non-annular structure.
本发明提出了一种可展开的环形螺旋桨及跨域航行器,属于环形螺旋桨领域,包括桨毂、桨叶及锁定部,桨叶为柔性材料制成,桨叶弯曲形变为第一形态或者回弹复位为第二形态,桨叶一端与桨毂外周壁固接并设为根部,桨叶另一端为自由端并设为梢部;桨叶处于第一形态并弯成环形,梢部与锁定部相连接;锁定部放开梢部,桨叶切换至第二形态。本发明的环形螺旋桨叶由柔性材料制成而能够弹性形变,通过将桨叶弯成环形并将其梢部固定在锁定部上,形成的环形螺旋桨更适用于跨域航行器在水下航行的场景,而当桨叶的梢部脱离锁定部的控制而使桨叶复位形变为非环形螺旋桨,其更适用于跨域航行器在空中航行的场景,使桨叶具有从环形结构切换到非环形结构的能力。
