Embodiment Construction

[0066] figure 1 Depicted in is an emergency oxygen system 1 constituting an exemplary embodiment of the present invention.

[0067] The emergency oxygen system 1 is intended to deliver supplementary breathing gas (oxygen) to passengers on board the aircraft. The emergency oxygen system 1 is implemented in the aircraft, more precisely in the aircraft cabin. The cabin of the aircraft is pressurized such that the cabin ambient air 4 is pressurized and includes a standard oxygen rate (about 21%). emergency oxygen system 1 is intended to deliver supplemental breathing gas (oxygen) to passengers on board the aircraft in case of depressurization due to failure of pressurization devices or uncontrolled leaks between the cabin and the outside, and / Or when toxic gases, especially smoke, are present in the cabin ambient air 4 . In a variant, the emergency oxygen system 1 can deliver supplemental oxygen to the crew.

[0068] like figure 1 As shown, the emergency oxygen system 1 main...

Abstract

An emergency oxygen system (1) for aircraft comprising: a breathing gas supply circuit (10) to be connected upstream to a source of breathing gas (12) and downstream to at least one mask (14), a flowcontrol valve (15, 18) configured to adjust the flow of breathing gas supplied to the mask (14), an electronics board (20) configured to control the flow control valve (15, 18), a power source (2), aswitching device (30) interposed between the power source (2) and the electronics board (20), the switching device comprising a switch (T1) configured to have a first state in which power from the power source (2) is supplied to the electronics board (20) and a second state in which the electronics board (20) is not supplied with power from the power source (2).

Description

technical field [0001] The present invention relates to an emergency oxygen system for an aircraft and a method of operating an emergency oxygen system. Background technique [0002] During the cruise portion of the flight, most commercial airliners operate at altitudes in excess of fourteen thousand feet. At these altitudes, there may be insufficient oxygen in the ambient air to sustain human consciousness or life. Accordingly, the cabin of the aircraft is pressurized, usually to an altitude equal to approximately eight thousand feet. At such "chamber altitudes", enough oxygen is usually present in the ambient air to avoid hypoxia and thus sustain human consciousness and life. [0003] For example, when an aircraft flies above, say, fourteen thousand feet, a loss of cabin pressure poses a risk for passengers (and crew) to experience hypoxia. Accordingly, aircraft are often equipped with emergency oxygen systems configured to temporarily provide supplemental oxygen to pas...
