The invention discloses an autorotorcraft landing gear, and relates to the technical field of aircrafts, the autorotorcraft landing gear comprises a rack, a fixed arm and a support arm, a shock absorption mechanism is arranged between the rack and the fixed arm, an anti-impact mechanism is arranged between the rack and the support arm, the top of the support arm is hinged to the anti-impact mechanism, and the top of the support arm is hinged to the shock absorption mechanism. The bottom of the supporting arm is hinged to the fixing arm. The landing gear designed by the invention has excellent impact resistance and impact absorption performance, and risk factors caused by impact during landing of the autorotorcraft are greatly reduced; the undercarriage is provided with the shock absorption mechanism and the shock resistance mechanism, composite shock absorption is utilized, expensive carbon fibers or aviation aluminum materials do not need to be used, the mechanical structure is simple, manufacturing and assembling are convenient, and the cost of the undercarriage can be reduced again; the invention further provides a plurality of structures which can be adjusted according to actual use conditions, and the practical usability is very wide.

    本发明公开了一种自转旋翼机起落架,涉及飞行器技术领域,包括机架、固定臂和支撑臂,所述机架和所述固定臂之间设置有吸震机构,所述机架和所述支撑臂之间设置有抗冲击机构,所述支撑臂的顶部铰接在所述抗冲击机构上,所述支撑臂的底部铰接在所述固定臂上。本发明设计的起落架具有优秀的抗冲击和吸收冲击性能,大大降低了自转旋翼机降落时因冲击产生的危险因素;本发明设置有吸震机构和抗冲击机构,利用复合减震,无需使用价格昂贵的碳纤维或航空铝材,机械结构简单,制造组装方便,能再次降低起落架的成本;本发明还提供了多处可根据实际使用情况调整的结构,具有非常广泛的实际使用性。
