초록 ▼

A system and apparatus are disclosed for providing oxygen-rich gas for breathing by aircrew and passengers of commercial passenger aircraft. Oxygen-rich gas output by molecular sieve concentrator apparatus 11 is delivered by way of a compressor 17 and a priority valve 24 to a flight crew gas storage cylinder 22 and passenger gas storage cylinders 23. An electronic control unit (ECU) 38 controls cycling of the concentrator apparatus 11 in obtainment of gas enriched with oxygen to at least 90%. The ECU is connected for receiving signals from a monitor 35 which senses the content of oxygen in gas delivered by the concentrator apparatus. The ECU receives signals from pressure sensors 42 and 43 in the cylinders 22 and 23 to initiate start up of the system when the content of these cylinders is sensed to have fallen below a predetermined value. The ECU is connected to switch the priority valve for preferential charging of the crew cylinder when both sets of cylinders require charging. The ECU is further connected for opening a vent valve 46 whereby on start-up of the system, gas delivered by the concentrator apparatus is vented to ambient until the oxygen concentration is sensed to be 90% or more. The system reduces the requirement for ground servicing and weight of oxygen gas storage cylinders carried by present day passenger carrying aircraft. Also, it enables the number of cylinders to be kept at a minimum in meeting the requirements for emergency oxygen on new air routes which are now being developed.

Apparatus for supplying oxygen-rich gas for breathing by crew and passengers of a passenger carrying aircraft, comprising first gas storage means adapted for pre-charging with oxygen-rich gas and connected by first supply line means for delivering said oxygen-rich gas to an aircraft flight crew cabin for continuous breathing by a flight crew member flying the aircraft above a predetermined altitude and for breathing by all flight crew in the event of cabin decompression; second gas storage means adapted for pre-charging with oxygen-rich gas and connected by second supply line means for delivering said oxygen-rich gas for breathing by occupants of an aircraft passenger cabin in the event of cabin decompression; means for monitoring the content of oxygen-rich gas in the first and second gas storage means; molecular sieve oxygen concentrator means having a supply air inlet end and an oxygen-rich gas outlet end; supply air delivery means adapted for connection between a source of supply air and the inlet end of the concentrator means; oxygen-rich gas delivery means adapted for connection between the outlet end of the concentrator means and the first and second gas storage means; means for sensing the content of oxygen-rich gas in the first and second gas storage means; means for initiating operation of the concentrator means when the content of oxygen-rich gas in one or both of the first and second gas storage means is sensed to have fallen below a required content value; means for monitoring the content of oxygen in oxygen-rich gas delivered by the concentrator means; spill valve means connected in the oxygen-rich gas delivery means; means connecting the spill valve means with the oxygen-rich gas sensing means whereby the spill valve means is signalled by the sensing means to open and vent to ambient oxygen-rich gas delivered by the concentrator means when the oxygen content of said gas is sensed as being below a required value; compressor means connected in the oxygen-rich gas delivery means; means connecting the compressor means with the oxygen-rich gas sensing means whereby the spill valve means is signalled to close and the compressor means is signalled to commence operating to increase the pressure of oxygen rich gas delivered by the concentrator means when the content of said gas is sensed to be above the required value for delivery to the first and second gas storage means.
