An aircraft with at least one elastically deformable component and method for determining the onset of a wear-related component remaining service life on an aircraft

摘要

The invention relates to an aircraft with at least one elastically deformable component as a structural part and / or bearing part, to which in the course of operation of changing flight maneuver dependent, different deformation forces act, leading to a component wear duration limiting component wear. According to the invention, a time-repeating, respectively identical flight maneuver is predetermined, to which a specific, respectively identical deformation force is assigned. Upon detection of such a predetermined flight maneuver (2), a measuring operation is automatically started by a start signal and carried out (3), wherein a component deformation is measured as a parameter for a current component stiffness. Then, a comparison of a current deformation measurement with respect to previous stored deformation measurements is made (9) with the result that the deformation measurements stored over a relatively long useful life, or the component stiffness in a low slope plateau region (17) are about the same secure component function is detected, or that thereafter over a short period of use successively detected deformation measured values are successively and progressively larger, whereby the beginning of a wear-dependent predeterminable component remaining service life is determined and a corresponding warning information is output (12).
