The present invention relates to a network for an aircraft, comprising a master device and a plurality of slave devices (3a, 3b, 3c) connected in series in a daisy-chain arrangement. Each of the slave devices (3a, 3b, 3c) has an associated unique identifier taken from a predetermined ordered sequence of identifiers. The master device (2) is adapted to transmit polling data packets (8) along the series of slave devices (3a, 3b, 3c), each including one and only one identifier, and the polling data packets (8) are transmitted in successive sequences, each including for each of the slave devices (3a, 3b, 3c) one and only one polling data packet (8) and including the polling data packets (8) in the order defined by the predetermined sequence of identifiers. Each of the slave devices (3a, 3b, 3c) comprises a first data interface (4) for connection in an upstream direction, a second data interface (5) for connection in the downstream direction, and a processing unit (6) adapted to compare for each received polling data packet (8) the identifier thereof with the identifier of the respective slave device (3a, 3b, 3c), and output a response data packet (9) to the master device (2) if the two identifiers match, and forward the polling data packet (8) to the second interface (5) at least if the two identifiers do not match. Each processing unit (6) comprises an adjustable time delay element (7) adapted to delay the output of the response data packets (9) by an adjustable delay period (19). For each of the slave devices (3a, 3b, 3c) the delay period (19) is set to a value depending on the relative position of the respective slave device (3a, 3b, 3c) in the daisy-chain arrangement, such that it continuously decreases from slave device (3a, 3b, 3c) to slave device (3a, 3b, 3c).

The present invention relates to a network for an aircraft (1), comprising a data line (3), and at least two network access devices (4), comprising a first interface (9) and at least one second interface (10) and being connected to the data line (3) via the first interface (9). Identifiers are assigned to the second interfaces (10) in pairs. The network access devices (4) are adapted to receive and/or transmit data via the first interface (9) in first data frames (5) having a fixed format and comprising a first portion (17) and second portions (18) following the first portion (17), the first and second portions (17, 18) having predefined lengths and locations within the first data frame (5). The network access devices (4) are to transmit in the first data frames (5) a sequence of second data frames (12) and, for each second interface (10), a sequence of third data frames (13a, 13b) received on the second interfaces (10), wherein the network access device (4) includes a first processing unit (7) adapted to insert the second data frames (12) in the first portion (17) of the first data frames (5), split each third data frame (13a, 13b) into a plurality of fragment frames (20a, 20b), including a part (19a, 19b) of the respective third data frame (13a, 13b) and reassembly information allowing regeneration of the third data frame (13a, 13b) from the fragment frames (20a, 20b), and insert the fragment frames (20a, 20b) into the second portions (18). The network access devices (4) are also adapted to process received first data frames (5) by extracting the second data frame (12) and the fragment frames (20a, 20b), to regenerate the corresponding third data frames (13a, 13b), and to output the regenerated third data frames (13a, 13b) on corresponding second interface (10).

The invention is an inlet system (300) for an Auxiliary Power Systems ("APS") (200), the said inlet system (300) comprising: - an inlet (310) having an entrance aperture (313) able to receive a flow (F) from an airstream, - at least an APU air intake duct connection (318, 418a, 418b) able to drive the flow (F) directly to client functions of the APS (200), - a divider (215) positioned inside the inlet (310), able to divide the flow (F) to feed in air each client function of the APS (200), the divider (215) being a deflector able to move inside the inlet (310) defining variable geometry channels (316a, 316b), in order to guide, optimize and regulate dynamically the flow (F) according to the volume and/or rate of flow (F) required by each active client function of the APS (200).

Described and claimed is a method for transmitting continuously created data items from an aircraft to a receiver. The data items are of a plurality of data types and each have a different priority. For each data type a live LIFO buffer and a main LIFO buffer are provided. In a regular operation mode continuously created data items are continuously stored in the main buffers. In a transmission operation mode continuously created data items are continuously stored in the live buffers, consecutive data packets are transmitted and for each data packet the data is selected from the buffers, wherein data items stored in live buffers are transmitted before data items stored in main buffers and data items of higher priorities are transmitted before data items of lower priorities. Further, a transmitter and an aircraft are described and claimed.

The present invention provides to a system (1) for producing components of composite material, and especially elongate or continuous components of fibre-reinforced polymer. In this regard, the system (1) comprises: a winding mechanism (4) for winding an elongate sheet (3) of composite material about a winding axis (X) that is at an angle (²) to a perpendicular to a longitudinal axis (L) of the elongate sheet (3) so as to form a helical coil (5) of wound sheet (3); a mechanism for drawing or conveying the helical coil (5) of wound sheet (3) along a process path (P), wherein the process path (P) is preferably substantially parallel to the winding axis (X); and a shaping mechanism (10) for forming or shaping the coil (5) of wound sheet (3) as it is drawn or conveyed along the process path (P). In addition, the present invention provides a corresponding method of producing a composite component.
