  • Method of and apparatus for monitoring the condition of structural components
    Patent number: 8779943
    Abstract: The present invention relates to a method of monitoring the condition of structural components, in which an optical sensor in conjunction with a computing unit ascertains image deviations from successive images of the structural components to be monitored, and therefrom ascertains changes in shape of the structure. Robust three-dimensional scanning of the structural components is possible when using two or more sensors. The invention further relates to an apparatus for monitoring the condition of structural components having an optical sensor and an apparatus having two or more sensors. Finally the invention relates to an aircraft in which the methods or apparatuses according to the invention are used.

  • Expansion tool and method for cold expansion of holes
    Patent number: 8302448
    Abstract: A method for cold expansion of a hole formed in a work piece. The method comprises providing a body comprising at least a cylindrically shaped part having an inner hole in axial direction of the body. The body further comprises along its circumferential direction a plurality of members which are movable in radial direction of the body, such that the outer diameter of the cylindrical part of the body can be changed.
