Abstract
The aircraft emergency oxygen supply system includes one or more sources of supplemental breathable oxygen, one or more inlet valves for one or more breathing devices, connected to the inlet valves, and one or more cabin air pressure transducers. A pressure controller controls the inlet valves in response to the one or more cabin air pressure transducers. One or more second pressure transducers may connected to conduits downstream of inlet valves to be monitored, and the pressure controller may also control operation of the inlet valves in response to the one or more second pressure transducers.
Claims20
An emergency oxygen supply system for an aircraft with a pressurizable passenger cabin comprising:
- a first on-off inlet valve connected via a first conduit to a first source of supplemental breathable oxygen and not connected to a second source of supplemental breathable oxygen;
- a second on-off inlet valve connected via a second conduit to the second source of supplemental breathable oxygen and not connected to the first source of supplemental breathable oxygen, the first conduit and second conduit are separate;
- at least one first breathing device configured to receive supplemental breathable oxygen from the first source of supplemental breathable oxygen and not from the second source of supplemental breathable oxygen, and at least one second breathing device configured to receive supplemental breathable oxygen from the second source of supplemental breathable oxygen and not from the first source of supplemental breathable oxygen;
- a first manifold connected between the first on-off inlet valve and the at least one first breathing device, and a second manifold connected between the second on-off inlet valve and the second at least one breathing device;
- and
- a pressure controller that receives a cabin air pressure input signal and controls operation of the first and second on-off inlet valves by transmitting a single control signal to each of the first on-off inlet valve and the second on-off inlet valve based on the cabin air pressure input signal.
