Abstract: A method for load relieving a test object, wherein a load is applied by a multiplicity of hydraulic devices positioned side by side each introducing a partial load into the test object such that the test object has a minimum deflection in an area close to its fixation and a maximum deflection in an area far away from the fixation, wherein the load is reduced sequentially from the maximum deflection to the minimum deflection. A test rig is provided that enables an autonomous and non-synchronical load relief of a test object based on pressure difference. A test rig is provided that enables an autonomous and non-synchronical load relief of a test object based on a delay time and a control system for such test rigs.

Abstract: An optical measuring device for measuring a surface contour of an object, includes a tripod on which a camera platform is mounted, wherein on the camera platform at least two photo cameras are arranged for imaging the object comprising marking elements, and the at least two photo cameras are arranged on the camera platform in such a manner that imaging the object can be carried out from two different perspectives, wherein between the camera platform and the tripod a displacement device for the linear displacement of the camera platform in three directions that are independent of each other is arranged.

Abstract: A method and a device for the execution of the method for the reproduction of an impact event of a projectile, with any ratio of energy and impulse, wherein a feed rate of an impress element is controlled by taking account of an alteration in velocity that is proportional to the quotient of a resistance force and a freely selected projective mass.

Abstract: Stated is an impact test device for simulating an impact of a body on a vehicle, which impact test device comprises a movable carriage and an actuator that is attached to the movable carriage. With the movable carriage at a standstill the actuator can move in a linear manner an impact body against the vehicle in order to deform the vehicle and to accelerate the movable carriage away from the vehicle. Since the mass of the actuator is significantly lighter than that of the movable carriage, termination of the impact test may take place very quickly.

Abstract: The present invention provides a cover plate for covering at least portions of a door gap formed between a door covering and a fuselage cell of an aircraft or spacecraft, comprising: a fastening portion by which the cover plate can be mounted on an outer surface of the door covering; a contact portion which rests in a contacting manner against an outer skin of the fuselage cell when the door covering is closed; at least one corner portion associated with a corner of the door covering; and a side portion associated with a side of the door covering, the at least one corner portion and the side portion being configured to press the contact portion with a constant contact pressure against the outer skin of the fuselage cell when the door covering is closed.
