The invention discloses an aircraft landing gear shock absorber, an aircraft landing gear, an aircraft and related methods. The shock absorber comprises a stop surface (44) arranged to limit the extension of the shock absorber (6) and a corrugation element (48) configured to deform in the event that an extension load on the stop surface (44) exceeds a predetermined threshold. The corrugation element (48) may form part of an outer stop tube (46) of the shock absorber (6). The deformation of the corrugation element (48) can be identified by measuring the length of the fully extended landing gear by non-destructive testing, or by measuring a change in conductivity of the corrugation element (48).
本发明公开了飞行器起落架减震器、飞行器起落架、飞行器及相关方法。该减震器包括止动表面(44)和折皱元件(48),该止动表面布置成限制减震器(6)的延伸,该折皱元件构造成在止动表面(44)上的延伸载荷超过预定阈值的情况下变形。折皱元件(48)可以形成减震器(6)的外止动管(46)的部分。折皱元件(48)的变形可以通过下述方式来识别:通过无损检测来测量完全延伸的起落架的长度,或通过测量折皱元件(48)的导率的变化。
