The invention relates to a speed reducer suitable for an air-drop type unmanned aerial vehicle, and belongs to the technical field of aircrafts. The parachute comprises a parachute cover (1), parachute cords (2), a wire bundling hoop (3) and a connector (4), the connector (4) comprises a connector upper shell (5), a connector base (6), an upper ball bearing (7), a lower ball bearing, an upper connecting ring (8) and a lower connecting ring (9), the speed reduction device is in a cross-shaped parachute form, the lower connecting ring is connected with the decelerated cylindrical unmanned aerial vehicle through the parachute cords, and the parachute cords are connected with the lower connecting ring through the lower connecting ring. The upper connecting ring and the lower connecting ring are both installed in the connector shell, the maximum outer diameter of the upper connecting ring and the maximum outer diameter of the lower connecting ring are both slightly smaller than the inner diameter of the connector shell, the speed reduction and rotation reduction technology of the air-drop type unmanned aerial vehicle is broken through, speed reduction and rotation reduction of the air-drop type unmanned aerial vehicle in the parachute landing process are achieved, and the scheme is simple in design, high in reliability, simple in process, low in machining cost and light in weight; the popularization value is realized.

    本发明涉及一种适用于空投型无人机的减速装置,属于飞行器技术领域。本发明包括:伞面(1)、伞绳(2)、束线箍(3)、连接器(4),所述连接器(4)包括:连接器上壳体(5)、连接器底座(6)、上滚珠轴承(7)、下滚珠轴承、上连接环(8)和下连接环(9),所述减速装置采用十字伞形式,下连接环通过伞绳与被减速的筒装无人机相连,上下连接环均安装在连接器壳体内,上下连接环的最大外径均略小于连接器壳体的内径,本发明突破了空投型无人机减速减旋技术,实现了空投型无人机伞降过程的减速与减旋,该方案设计简约、可靠性高、工艺简单、加工成本低、质量轻,具有推广价值。
