Device for localizing sectional displacement of cover layer from sandwich fiber plate in e.g. aerodynamical active area, in air craft, has vacuum chamber arranged above panel by telemeter so as to determine lifting quality of cover layer

摘要

The device (1) has a vacuum chamber (2) mounted on a fiber component and provided with a support and a circulating gasket (3). The vacuum chamber is admitted with pressure up to -0.9 Bar by a vacuum generator. The vacuum chamber is closed by a radiation-permeable panel for a housing and arranged above the radiation-permeable panel by optical telemeters i.e. laser triangulation sensors (5, 6), that are positioned within measuring surfaces so as to contactlessly determine lifting quality of a cover layer. A wavelength range of laser of the sensors is 5 micrometers to 100 nanometers. An independent claim is also included for a method for localizing sectional displacement of a cover layer from a sandwich fiber plate in aerodynamical active areas in an air craft.
