The embodiment of the invention discloses a landing buffering structure for an aircraft. The landing buffering structure comprises a buffering assembly of an inverted-cone-shaped structure. The buffer assembly includes: a central buffer member located at a central position; and annular air bags which are arranged on the periphery of the central buffering component in a surrounding mode, wherein the inner diameters of the annular air bags are different, and the plurality of annular air bags with different inner diameters are mutually stacked to form an inverted cone-shaped structure. The buffering structure further comprises a shape follow-up component of an inverted-cone-shaped curved surface structure, and the shape follow-up component is fixed to the side, away from the aircraft, of the buffering assembly. According to the landing buffering structure, the crushing phenomenon caused to the central buffering component during landing is utilized, the supporting effect of the annular air bag is combined, automatic righting of the aircraft in the landing process is achieved, the landing buffering structure can consider aerodynamic design of the aircraft in the reentry process, the aerodynamic appearance and the aerodynamic bearing capacity of the aircraft are not affected, the attitude stability of the aircraft in the landing process is improved, and the landing safety of to-be-returned equipment and load samples in the aircraft is improved.

    本发明实施例公开了一种用于飞行器的着陆缓冲结构,包括呈倒锥状结构的缓冲组件;所述缓冲组件包括:位于中央位置的中央缓冲构件;以及围绕在所述中央缓冲构件外围的多个内径不同的环状气囊;多个内径不同的环状气囊相互堆叠呈倒锥状结构设置;所述缓冲结构还包括有呈倒锥状曲面结构的随型构件,所述随型构件固定于所述缓冲组件的背离飞行器的一侧。本着陆缓冲结构利用着陆时对中央缓冲构件造成的压溃现象,结合环状气囊的支撑作用,实现了飞行器着陆过程中的自动扶正,且该着陆缓冲结构能够兼顾飞行器再入过程气动设计,不影响飞行器气动外形和气动承载能力,增加飞行器着陆过程的姿态稳定性,提升飞行器内部待返回设备及载荷样品的着陆安全性。
