The invention provides an aircraft landing gear. The aircraft landing gear comprises a retractable actuator cylinder, a plate spring, an aircraft wheel and a tire, the folding and unfolding actuatingcylinder drives the plate spring to fold and unfold, one end of the plate spring is connected with the airplane wheel and the tire through a wheel shaft, the other end of the plate spring is providedwith a connecting shaft used for being hinged to an aircraft, and the cross section of the plate spring is gradually reduced from the folding and unfolding actuating cylinder to the wheel shaft. Compared with the prior art, the plate spring of the aircraft landing gear is made of the variable cross-section composite material, the deformation characteristic of the plate spring is good, the productweight can be obviously reduced, the product manufacturing cost is reduced, and the requirements for landing of light aircrafts and unmanned aerial vehicle landing gears, ground sliding impact and buffering, light weight and low cost are met; the aircraft undercarriage is simple in structure, simple in manufacturing process, high in material specific strength and high in specific rigidity.

    本发明提供一种飞行器起落架。所述飞行器起落架包括收放作动筒、板簧、机轮和轮胎,所述收放作动筒驱动所述板簧收放,所述板簧的一端通过轮轴与所述机轮和轮胎连接,所述板簧的另一端设有用于铰接飞行器的连接轴,所述板簧的横截面自所述收放作动筒向所述轮轴逐渐减小。与相关技术相比,本发明所提供飞行器起落架的板簧为变截面复合材料,其变形特性好,可以明显减轻产品重量,降低产品制造成本,满足轻型飞机及无人机起落架着陆及地面滑行冲击及缓冲,以及轻质化及低成本的要求;所述飞行器起落架结构简单,制造工艺简单,材料的比强度大、比刚度大。
