摘要:
In a multicore type error correction processing system which can simultaneously cope with a plurality of error correction methods and a plurality of code lengths, an interconnect part 11 has a barrel shifter which extends across a plurality of error correction processing parts 12a-12c. An error correction process can be selectively performed by collectively using a group of the plurality of the error correction processing parts 12a-12c or by individually using each of individual error correction processing parts 12a-12c in response to interconnection configuration information. With this structure, the plurality of the error correction processing parts 12a-12c are collectively used if computation resources are insufficient and an idling error correction processing part is assigned to another error correction process if computation resources are excessive.

A fuselage structure, particularly an aircraft door (1) of composite material comprising at least one panel (2) and at least one beam (3) mounted to each other and the panel (2) with the panel (2) being formed of at least one group of composite layers (5, 6, 20). The at least one beam (3) is provided at least at one of its respective ends (10, 11) with a flange (13) suitable for adhesive engagement with the at least one panel (2). The at least one group of composite layers (5, 6, 20) of the panel (2) is in form locking engagement with this flange (13) of the beam (3).
摘要:
A method of fabricating components (23) based on fiber-reinforced plastics material, in particular with the help of a wrapped mold core (10), includes the following steps:a) fabricating the mold core (10); b) wrapping the mold core (10) with a wrapper (14) that withstands resin; c) applying fiber semi-finished products (16) and introducing resin to create the plastics component (23); and d) hardening the plastics component (23) under the effect of temperature; which method is improved by the fact that, under all circumstances, and during hardening in step d), substantial pressure equilibrium is established across the fiber semi-finished product (16, 20) between ambient pressure (pu) and the pressure (pk) inside the core. A device is also described.
摘要:
A composite element made from a preform of fiber-reinforced plastic material arranged around a core with a multi-layer thermoplastic foil between the preform and the core and a method for fabrication of such a composite element. At least one of the layers of said multi-layer thermoplastic foil has a different melting temperature from the melting temperature of at least one of the other layers.

The invention relates to an aircraft door arrangement, especially for an aeroplane, said arrangement comprising a door, a doorframe, a supporting section with a pivotal axis (AD) on the door side, along which the door is pivotably positioned, and a pivotal axis (AF) on the frame side, along which the supporting section (8) is pivotably positioned on the door frame. At least the pivotal axis (AD) on the door side is defined by two articulations (G1, G2) which are interspaced in the vertical direction (Y) of the supporting section (8), at least one (G1; G2) of said articulations comprising two vertically (Y) interspaced bearings (L1a, L1b). The inventive door arrangement also comprises a pivotal drive (10) which is arranged on the door side of the supporting section (8) and is used to pivot the door, and an output element (12; 14, 16) which is coupled to the pivotal drive (10) and the door and transfers an actuating movement of the pivotal drive (10) to the door. Said aircraft door arrangement is characterised in that one (L1b) of the two bearings (L1a, L1b) of at least one (G1) of the articulations (G1, G2) on the frame side is embodied (L1B) as a pivotal drive mounting (34) to which the pivotal drive (10) is fixed.
