Abstract: In some embodiments, an aircraft includes a structural assembly, a skin, and a snubber. The structural assembly comprises a first rigid element and a second rigid element. The first and second rigid elements are separated from each over by a void. The skin is disposed proximate to the structural assembly and adjacent to the void such that the skin would deflect into the void in response to an impact force received by the skin. The snubber is disposed in the void between the first and second rigid elements and positioned such that, when the skin deflects in response to the impact force, the skin contacts the snubber and the snubber reduces further deflection of the skin into the void.

Abstract translation: 在一些实施例中，飞行器包括结构组件，皮肤和缓冲器。 结构组件包括第一刚性元件和第二刚性元件。 第一和第二刚性元件由空隙分隔开。 皮肤靠近结构组件设置并且邻近空隙，使得皮肤响应于由皮肤接收的冲击力而偏转到空隙中。 缓冲器设置在第一刚性元件和第二刚性元件之间的空隙中并且定位成使得当皮肤响应于冲击力而偏转时，皮肤接触缓冲器，并且缓冲器减少皮肤进一步进入空隙的偏转。
