摘要:
A door and its frame especially in an aircraft are constructed for circulating air through the structure for preventing cold air from forming near the door in an aircraft cabin. For this purpose at least one air flow channel is provided in the door construction. The air flow channel communicates with at least one inlet port with at least one outlet port so positioned that air circulation is maintained through the door structure. The outlet port passes preferably through a cabin floor for discharging cold air into a space below the cabin floor.

A device for temperature regulation of sections of the interior of an aircraft includes a controlled mixer valve for the mixing of engine bleed air and air that is cooler than the engine bleed air in order to obtain pre-tempered mixed air flowing out of the mixer valve; a distribution line connected to the outlet of the mixer valve which is connected to the respective sections by at least two supply lines; individual heating units assigned to the respective sections; sensors assigned to the individual sections for the respective actual temperatures; transmitters for the respective nominal temperatures; and a regulator unit which controls the mixer valve dependent upon the respective nominal temperatures and the respective actual temperatures in the individual areas.

Aircraft fuselage with an upper deck, constructed as a passenger area, and a lower deck, including a freight area, and with a ventilation installation for the upper deck and lower deck, wherein a bilge area is constructed as a vacuum chamber against the freight area and is connected to the lower deck solely via flow orifices in the abutment area between a lower floor and the fuselage wall.

The invention concerns a cooling system for an aircraft with an air inlet (4) through which air from the environment of the aircraft enters a ram air channel (2), and an air outlet (6) through which air emerges from the ram air channel (2). A heat exchanger (10) is arranged in the ram air channel (2). A ventilation device (8) is in fluid communication with the ram air channel (2). Also connected to the ram air channel (2) is a distribution line (12) to cool at least one heat-loaded component of the aircraft, in particular a cabin air conditioning system, and/or to ventilate an installation space of the at least one heat-loaded component.

The present invention relates to a bus system for transmitting a data packet between multiple devices in an aircraft, which is based on the CAN data bus system, but has an expanded identification field, in which a fixed region is designed for identification of the manifold aircraft systems, through which each aircraft system may be addressed uniquely. According to an exemplary embodiment, the data packet may be sent with different priorities, through which “important” data packets have priority on the transmission medium.

In a cooling system (10) for cooling heat-generating installations (44, 46, 48) in an aircraft, with a refrigerating installation (12), at least one refrigeration consumer (44, 46, 48) and a refrigeration transport system (14) connecting the refrigerating installation (12) and the refrigeration consumer (44,46, 48), it is provided that the refrigerating installation (12) comprises at least one refrigeration machine (18, 20) which covers the maximum refrigeration requirement of the at least one refrigeration consumer (44, 46, 48) and in that the at least one refrigeration consumer (44, 46, 48) is supplied with cold generated in the refrigerating installation (12) via a refrigerating agent circulating in the refrigeration transport system (14).

A ram air channel (10) for the supply of ambient air in an aircraft includes a first air inlet (12) and a main flow channel (16) which extends downstream of the first air inlet (12). In order to guarantee that the systems on board the aircraft are supplied, in a simple and reliable way, with the required ambient air in any operational state of the aircraft, ie. both during the flight and on the ground, the ram air channel (10) has a second air inlet (24) which is independent from the first air inlet (12).
摘要:
A process for temperature regulation of sections of the interior of an aircraft with the following steps: recording of the respective actual temperatures and the respective nominal temperatures in the individual sections; mixing of engine bleed air and air which is cooler than the engine bleed air in order to obtain pre-tempered mixed air at a temperature which essentially corresponds to the lowest of the nominal temperatures recorded; distribution of the pre-tempered mixed air to all sections; and post-tempering of the mixed air distributed to the sections with higher nominal temperature corresponding to the differences between the respective nominal temperatures and the respective actual temperatures can be carried out in a device with a controlled mixer valve for the mixing of engine bleed air and air that is cooler than the engine bleed air in order to obtain pre-tempered mixed air flowing out of the mixer valve; to a distribution line connected to the outlet of the mixer valve which is connected to the respective sections by means of at least two supply lines; individual heating units assigned to the respective sections; sensors assigned to the individual sections for the respective actual temperatures and transmitters for the respective nominal temperatures; a regulator unit which controls the mixer valve dependent upon the respective nominal temperatures and the respective actual temperatures in the individual areas in such a way that the pre-tempered mixed air is of a temperature which essentially corresponds to the lowest of the nominal temperatures for all sections, and which controls the heating units assigned to the other sections corresponding to the differences between the respective nominal temperatures and the respective actual temperatures.

An improved organizer is provided that may be hung on a CPU, cubicle partition, file cabinet or other structure commonly found in an office or work place. The organizer may include a single backing member connected to a variety of organizing elements or may be of a saddle-type where two backing members are connected together by one or more overhang straps thereby providing organizing elements on either side of the structure, such as a CPU. The organizing elements include pockets, trays, baskets, bulletin boards, dry erase boards and other types of display surfaces.

A laundry basket has a bottom panel with a perimeter. A contiguous side wall extends generally upward from the perimeter of the bottom panel and terminates at an upper end. A basket interior is defined above the bottom panel and bounded by the side wall. A curved wall section of the side wall is curved concavely inward toward the basket interior. The bottom panel and the contiguous side wall, including the curved wall section, are formed of a primary material. A cushion pad is positioned generally at the upper end of the curved wall section and is formed from a secondary material that is softer than the primary material of the curved wall portion.
