Abstract:
An equipment mounting device and an installation arrangement for mounting an equipment to two fittings. The mounting device comprises a longitudinal carrier configured to be coupled to the equipment, and sized to span a space between the two fittings. A first coupling is disposed at a first end of the longitudinal carrier. The first coupling is configured to be coupled with a first of the two fittings and, when coupled with the first fitting, to prevent movement of the carrier in a first direction different from a direction along a longitudinal axis of the longitudinal carrier. A second coupling is configured to detachably couple with a second of the two fittings by receiving a part of the second fitting and, when coupled with the second fitting, to prevent movement of the carrier at least in the first direction and the direction of the longitudinal axis of the carrier.
Abstract:
A fuselage structure for an aircraft, comprising a fuselage vessel and a pressure bulkhead arranged in an end region of the fuselage vessel and having a central region extending in a planar manner and a connection region adjoining the central region in a radial direction and surrounding the central region and being secured to the fuselage vessel. The pressure bulkhead divides the fuselage vessel with respect to the longitudinal direction into a first region for subjecting to an internal pressure and a second region for subjecting to an external pressure which is lower than the internal pressure. The central region of the pressure bulkhead has an arching in the direction of the first region of the fuselage vessel.
Abstract:
A coupling device for coupling modules with each other, comprising: a coupling surface, a primary coupling member and at least two secondary coupling members. The primary coupling member is disposed on the coupling surface. A coupling axis disposed parallel to a direction of action of earth's gravitational acceleration extends through the primary coupling member. The at least two secondary coupling members are configured to be complementary to each other and are disposed on the coupling face, and respectively have a predetermined distance from the coupling axis.
Abstract:
A coupling member for coupling modules with each other. The coupling member comprises a coupling portion, which in turn has a coupling rim and at least two hook members disposed on the coupling rim. The coupling portion substantially corresponds in its outer contour to a spherical segment of a sphere with a predetermined spherical radius, wherein the coupling rim represents a circular disk of the spherical segment. In this case, an outer radius of the coupling rim is smaller than or equal to the spherical radius. The at least two hook members, in a lateral view, at least partially follow the outer contour of the spherical cap of the spherical segment. The at least two hook members are engageable with the hook members of a coupling portion of a second coupling member.
Abstract:
A structural member for an aircraft or spacecraft has at least one fiber plastic composite, the fiber plastic composite having at least one or a plurality of plies. The structural member also has at least one pre-stressing means providing internal stresses to the fiber plastic composite. The fiber plastic composite and the pre-stressing means are configured and arranged to form a balanced system the internal stresses of which are essentially balanced to zero in a cured state of the said system. The balanced system of the structural member is able to counteract loading stresses exerted to the airframe in service such, that a damage caused by the loading stress is easily detectable visually.
Abstract:
A device for building a three-dimensional structure in layers includes at least one supply unit, at least one laser unit and one table, wherein the table comprises a circular surface and is adapted for rotating the circular surface around a central axis. The supply unit is adapted for applying a powdery material in layers on the circular surface of the table. The laser unit at the same time can partly or completely melt powdery material already applied by the supply unit while the circular surface is rotating.
Abstract:
A connection system includes two connecting elements each having a respective connecting flange on which a plurality of coupling elements are arranged along a peripheral direction and which has a substantially round external profile; and a coupling belt, on which a plurality of opposing coupling elements are arranged which are configured to form a positive-locking connection with the coupling elements of the two connecting elements for the mutual rotation-proof fixing of the two connecting elements.
Abstract:
A load bearing element for attachment of a heat generating unit to a heat sensitive supporting structure, wherein said load bearing element includes at least one body integrally formed by additive layer manufacturing, ALM. The body is adapted to provide a controlled heat transfer from said heat generating unit to said heat sensitive supporting structure.
Abstract:
A fixing device for fixing an element, in particular a line, a cable, a pipe, a hose or the like in an aircraft or spacecraft, to a component, includes an LFS fixing structure, the latching body and/or the flange portion of the LFS fixing structure having a tolerance compensator for compensating thickness tolerances of the entire arrangement.
Abstract:
A connecting device for manufacturing a peeling-stress-resistant connection between two components. The connecting device includes a carrier, which has a first surface and a second surface opposing the first surface. The connecting device further includes a plurality of hook and loop elements which extend both from the first and the second surface of the carrier and each have at their free ends facing away from the first or the second surface of the carrier a hook and loop head, which is arranged to enter into a hook and loop connection with a component comprising a fiber-reinforced composite material.
