    • A method and device for detecting an overstepping of design loads of the fin of an aircraft. The device includes a set of information sources and a section for determining, with the aid of information emanating from the set of information sources, a current bending moment. The device further includes a section for determining, with the aid of information emanating from the set of information sources, a current twisting moment, and a section for carrying out a comparison by comparing the pair formed by the current bending moment and the current twisting moment with a safety envelope representing a chart formed in a plane on the basis of pairs of values of bending and twisting moments and defined so that, for any pair which lies outside the safety envelope, there exists a risk of appearance of permanent deformation on the fin. The device further includes a section for determining whether a structural inspection of the fin has to be performed, at least on the basis of a comparison result provided by the comparison section.
    • 一种用于检测飞行器翅片的设计载荷超标的方法和装置。 该装置包括一组信息源和一个部分,用于借助于从该组信息源发出的信息确定当前的弯矩。 该装置还包括一个部分,用于借助于从该组信息源发出的信息来确定当前的扭转力矩,以及用于通过比较由当前弯矩和当前扭转力矩形成的对来执行比较的部分 其中安全信封代表基于弯曲和扭转力矩值的平面中形成的图表,并且被定义为使得对于位于安全壳体之外的任何一对,存在在翅片上出现永久变形的风险 。 该装置还包括至少基于由比较部分提供的比较结果来确定是否必须执行散热片的结构检查的部分。
