能提供涉及装置疲劳相关损坏程度信息的旋翼飞机的装置
Abstract:
本发明涉及用于插入在旋翼飞行器的可能经受反复相对运动的两个部件之间的装置(205)，所述装置包括：至少两个框架元件(205A；205B)，所述框架元件用于被安装在飞行器的两个部件的至少一个上；以及至少一个位于两个框架元件之间的弹性体层(21)，所述至少一个层(21)由第一表面(SI)、第二表面(SE)以及外表面(Sext)限定，第一表面属于所述装置的内部体积，第二表面也属于所述装置的内部体积，外表面不属于所述装置的内部体积(Vint)，其特征在于，所述装置(205)在所述装置的内部体积之内包括至少两个袋(250‑253)，每个袋位于距外表面(Sext)预定距离处，每个袋充注有产品(P)，所述产品能够在裂纹已经从外表面(Sext)朝向袋扩展时流出其袋。
Abstract(English):

A device configured for insertion between two parts of a rotary wing aircraft that are likely to undergo a repeated relative movement. The device includes at least two frame elements intended to be mounted on at least one of the two parts of the aircraft, and at least one layer of elastomer positioned between the two frame elements, the at least one layer defined by a first surface belonging to the inner volume of the device, a second surface also belonging to the inner volume of the device, and an outer surface not belonging to the inner volume of the device. The inner volume of the device includes at least two independent pouches each positioned at a predetermined distance from the outer surface, each pouch being filled with a product capable of flowing outside its pouch when a crack has spread from said outer surface toward the pouch in question.
