Embodiment Construction

[0034] figure 1A bleed air supply system 10 according to the prior art is shown. The bleed air supply system 10 includes a bleed air source 12 that discharges hot air from an engine 13 and is connected to a bleed air supply device 14 . A shut-off valve 16 actuated via a shut-off circuit 18 is arranged between the bleed air source 12 and the bleed air supply device 14 . If the shutoff circuit 18 is cut off, the shutoff valve 16 closes and the air supply from the bleed air source 12 is interrupted. The bleed air supply means 14 supplies hot air to consumers (not shown) in the aircraft.

[0035] Cool air supply system 20 directs cool air from the aircraft environment via cooling inlet 22 to heat exchanger 24 . The cold air supply system 20 may be connected to, for example, an air inlet of the engine 13 . A heat exchanger 24 is also connected to the bleed air source 12 .

[0036] The cold air supply system 20 comprises a cold air line 28 and a control valve 30 adapted to be c...

Abstract

The present invention relates to a wiring arrangement (50) for protecting a bleed air supply system (10) of an aircraft against overheating, the bleed air supply system (10) comprising a bleed air source (12), a bleed air feed (14), a shutoff valve (16) arranged in the bleed air feed (14) and a leakage monitoring device (38) with a monitoring control device (39), which is connected via a shutoff circuit (18) to the shutoff valve (16) in such a way that the shutoff valve (16) is closed when the shutoff circuit (18) is interrupted, it being provided that the wiring arrangement (50) comprises a thermal switch (52), which is connected in series with the shutoff valve (16) and the monitoring control device (39) to the shutoff circuit (18) and which, once a predetermined limit temperature (TG) has been exceeded, interrupts the shutoff circuit (18).

Description

technical field [0001] The invention relates to a circuit arrangement for preventing the overheating of the bleed air supply system of an aircraft, the bleed air supply system includes a bleed air source, a bleed air supply device, and is arranged between the bleed air supply device and the bleed air source A shut-off valve in between, and a leakage monitoring device with a control device, wherein the control device is connected to the shut-off valve via a shut-off circuit such that the shut-off valve is closed when the shut-off circuit is cut off. The invention also relates to a bleed air supply system with such a wiring arrangement. Background technique [0002] In modern aircraft there is usually a considerable number of devices to which warm and compressed air must be supplied. One of the most important consumers of this air is the air-conditioning system of commercial aircraft, which must be artificially created due to the high flight altitudes of modern commercial air...
