Definitions
- the present invention relates to on-board systems for generating and supplying oxygen (designated in aeronautics by the acronym "OBOGS”) and nitrogen (designated in aeronautics by the sign "OBIGGS”).
- OBOGS devices were developed first, for the supply of oxygen to pilots of military aircraft, then, more recently, for the continuous supply of aircraft passengers.
- OBOGS devices are generally of the type of separation of air component by alternating pressure adsorption designated by the acronym PSA.
- OBIGGS devices then appeared to inert the fuel tanks of helicopters, then of civil planes.
- OBIGGS devices are generally of the type that separates the air component by permeation with polymer membranes.
- the invention provides an on-board system for generating and supplying oxygen and nitrogen comprising: - a first air separator device having an air inlet and at least one outlet, - a second separator device of air having an air inlet and an outlet, - a third air separator device having an air inlet and at least one outlet, - the air inlets of the first and second devices being connectable to a source of pressurized air - the first separator device having an outlet connectable to at least one compartment to be inerted; and - the outputs of the second and third separator devices being connectable to an oxygen supply circuit.
- the third air separator device is of the solid electrolyte type
- the outlet of the third air separator device is connectable to an on-board oxygen tank
- - the second separator device d air is advantageously of the adsorption type
- - the first air separator device is advantageously of the type with polymer membranes.
- the system on board a large civil aircraft essentially comprises a first air separator device of type OBIGGS 2, a second air separator device of type OBOGS 3, and a third air separator device of type OBOGS 4.
- the air separator device OBIGGS advantageously of the type with polymer membranes, such as those marketed by Medal Corp. in the United States, comprises an inlet for pressurized air 5, an outlet for a mixture enriched in nitrogen 6, and an outlet 7 for a mixture depleted in nitrogen.
- the OBOGS 3 air separator device advantageously of the PSA type, with high performance adsorbents, for example with LiLSx zeolite, such as those sold by the Applicant, comprises an inlet 8 for pressurized air, an outlet 9 for enriched mixture. in oxygen and an outlet 10 of mixture depleted in oxygen.
- the inputs 5 and 8 of the first (2) and second (3) air separating devices are connectable, via a distribution / regulation valve 11 to a supply line 12 coming from compressor stages of the engines 13 of the aircraft 1, the line 12 passing through a heat exchanger 14 to cool the compressed gas coming from the engines, and incorporating a control valve 15 and an upstream filter 16.
- the nitrogen outlet 6 of the OBIGGS device 2 is connectable, via a valve distribution 13, to circuits 14a 14b for inerting cargo hold compartments 15 or fuel tanks 16, 17, powering the propulsion engines and the auxiliary equipment for supplying energy to the aircraft.
- the oxygen outlet 9 of the OBOGS device 3 is connected, via a downstream filter 17 and a flow regulator 18, to a circuit 19 for supplying oxygen to the masks 20 of the cockpit and 21 of the passengers in the cabin.
- the OBOGS 4 air separator device with ceramic membranes advantageously of the zirconia type doped with yttrium, has an electrical current inlet 32, an inlet 22 for the admission of air at cabin pressure, an outlet 23 of mixture depleted in oxygen and an outlet 24 of high purity oxygen (greater than 99.9%) at a pressure greater than 100 bar absolute in a secure pipe 25 opening into the flow control device 18 and incorporating a buffer tank d pressurized oxygen 26.
- the regulation valve 15 is controlled by an electronic control device 27 receiving pressure and temperature signals 28 upstream of the line 12 and 29 for measuring the oxygen content in the outlet lines of the separator devices 2 and 3 and of setpoint signals 30 from the cockpit.
- the waste outlet 7 and 10 of the separator devices 2 and 3 communicate with a line 31 for evacuation from the aircraft.
- the separating devices 2 and 3 can be implemented sequentially and / or temporarily simultaneously to supply nitrogen and oxygen respectively from the compressed air. engines and that the reserve of ultra pure oxygen in the tank 26, renewable at will by actuating the separator device 4, can be used, being diluted, in addition to all or part of the flow of oxygen of medium purity available in outlet 9 of the separator device 3.
- the OBIGGS 2 can provide a flow rate of 150 to 250 m 3 / h, typically around 200 m 3 / h of gas mixture having a nitrogen content greater than 90% under a relative pressure of 2-3 bars
- the ceramic OBOGS 4 can provide a flow rate of 0.05 to 0.1 m 3 / h of pure oxygen under a pressure greater than 110 bars, typically around 130 bars .
