摘要:
An air duct for supplying ambient air in an aircraft includes an air inlet, a flow duct portion and a feed device that is devised to feed ambient air through the air inlet and the flow duct portion. A flow control flap closes the air inlet in a first position, releases a first flow cross-section of the air inlet in a second position and releases a larger second flow cross-section of the air inlet in a third position. The flow control flap is designed to not increase drag significantly in the second position while still enabling flow through the flow duct portion, while increasing drag to increase air fow through the flow duct portion in the third position.

Cooling of an electronic device in an aircraft by case-by-case single-phase or two-phase coolingThere is proposed a method for cooling an electronic device in an aircraft (11), comprising the following steps:circulating a coolant in a cooling circuit,cooling the electronic device (2) by means of the coolant, andin an aircraft outer-shell heat exchanger, emitting the heat taken up by the coolant. The coolant evaporates, at least partially, during the cooling of the electronic device (2), and condenses in the aircraft outer-shell heat exchanger (7). The coolant circulates in the coolant circuit by natural convection.

The invention relates to an air duct (10) for supplying ambient air in an aircraft, comprising an air inlet (12), a flow duct portion (16) extending downstream of the air inlet (12) and a feed device (22) that is devised to feed ambient air through the air inlet (12) and the flow duct portion (16). A flow control flap (24) closes the air inlet (12) in a first position, releases a first flow cross-section of the air inlet (12) in a second position and releases a second flow cross-section of the air inlet (12), which is larger than the first flow cross-section, in a third position. The flow control flap (24) is so designed and disposed that a first surface portion (28) of the flow control flap (24), in the second position of the flow control flap (24), is aligned in the region of the air inlet (12) substantially parallel to an aircraft outer skin portion (18) is surrounding the air inlet (12), and that the first surface portion (28) of the flow control flap (24), in the third position of the flow control flap (14), is aligned in the region of the air inlet (12) at an angle to the aircraft outer skin portion (18) surrounding the air inlet (12).

摘要:
A system (10) for ventilating an explosion hazard region (12) of an aircraft comprises a ram-air channel (16), which has an air inlet for feeding ambient air into the ram-air channel (16) as well as an air outlet (18). The ram-air channel (16) is devised to feed air to a device that is to be cooled on board the aircraft. A ventilation line (22) has an air inlet (24) for feeding air flowing through the ram-air channel (16) into the ventilation line (22) as well as an air outlet (26). The ventilation line (22) is devised to feed air to a region (12) of the aircraft that is to be ventilated. An accumulator (28) is disposed between the ram-air channel (16) and the air inlet (24) of the ventilation line (22) and is devised to convert the dynamic pressure of the air flow conveyed through the ram-air channel (16) at least partially into static pressure.
