Abstract
An air management system with a set of compressed air sources for supplying pressurized air to air consumer equipment. In particular, either an air bleed system, electrical compressors, or a combination thereof may perform such supplying of compressed air depending on the aircraft operation condition.
Claims11
A method for supplying pressurized air to air consumer equipment, the method comprising:
- providing an air management system comprising:
- at least one air consumer;
- at least one air source;
- at least one gas turbine engine having a single bleed air port, the single bleed air port located at a low-intermediate compressor stage of the at least one gas turbine engine;
- an air bleed system in fluid communication with the at least one gas turbine engine via the single bleed air port of the at least one gas turbine engine, the air bleed system being configured to supply compressed air to the at least one air consumer;
- at least one electrical compressor in fluid communication with the at least one air source, the at least one electrical compressor being configured to supply compressed air to the at least one air consumer;
- and
- a controller configured to receive an input relative to an aircraft operation condition and selectively operate at least one of the air bleed system and the at least one electrical compressor based on the received input;
- receiving by the controller the input relative to the aircraft operation condition;
- operating at least one of the air bleed system and the at least one electrical compressor based on the received input;
- and
- operating by the controller at least one of the air bleed system and the at least one electrical compressor, depending on the received input, so that:
- in taxiing, the at least one electrical compressor supplies the compressed air to the at least one air consumer;
- in taking-off, the at least one electrical compressor supplies the compressed air to the at least one air consumer;
- in the climb, the at least one electrical compressor supplies the compressed air to the at least one air consumer up to the pre-determined altitude;
- then, the air bleed system supplies the compressed air to the at least one air consumer;
- in the cruise, the air bleed system supplies the compressed air to the at least one air consumer;
- and
- in descent, holding, and landing, the at least one electrical compressor supplies the compressed air to the at least one air consumer.
