Abstract: In order to allow or improve a laminar air flow in a transition region between aerodynamic profile elements, a pressure plate arrangement is proposed. The pressure plate arrangement comprises a pressure plate body and at least one cover strip, in particular a sealing strip. The pressure plate body has an outlet region from which free-flowing sealant can exit during pressing. The cover strip already contains cured sealant and presses the free-flowing sealant flat in order to be able to form the transition region.

Abstract: A system and a method for evaluating performance of a porous skin of an aircraft including the porous skin, and a boundary layer control system. The performance evaluation system includes a first sensor providing data related to the performance of the porous skin. The performance evaluation system is further configured to clean the porous skin based on the performance of the porous skin determined using the data received from the first sensor in order to ensure that the porous skin operates at its maximum capability.

Abstract: An extrusion device and method for filling a groove with a filling compound. The extrusion device includes an extrusion head which is designed or configured to spring in and out in an extrusion direction of the extrusion device in a manner that is spring-resilient in the extrusion direction.

Abstract: A method to control operation of a robot includes generating at least one virtual image by an optical 3D measurement system and with respect to a 3D measurement coordinate system, the at least one virtual image capturing a surface region of a component. The method further includes converting a plurality of point coordinates of the virtual image into point coordinates with respect to a robot coordinate system by a transformation instruction and controlling a tool element of the robot using the point coordinates with respect to the robot coordinate system so as to implement the operation.

Abstract: A method for determining a surface profile change in a filling compound in a recess includes determining a first surface profile of a surface of the filling compound across the recess at an initial temperature; cooling or heating the recess comprising the filling compound to a predetermined measurement temperature; determining a second surface profile of the surface of the filling compound across the recess at the measurement temperature; and comparing the second surface profile with the first surface profile to determine the surface profile change.
