Abstract

A device and a method to generate electricity on board an aircraft, including plural generators and plural air-conditioning units having an outside air intake. This device includes a control to command air-conditioning units as emergency generators and a storage device.

Claims

1-11. -11. (canceled)

12. A device for electricity generation on board an aircraft, including plural generators and plural air-conditioning units having an outside air intake, the device comprising:

means to command air-conditioning units as emergency generators; and

a storage device.

13. A device according to claim 12, further comprising:

an essential bus bar on which critical loads of the aircraft and the storage device are connected; and

means to connect static converters, linked with the air-conditioning units, to the essential bus bar.

14. A device according to claim 12, wherein the storage device comprises storage batteries, super-capacitors, or kinetic accumulators.

15. A device according to claim 12, wherein the storage device comprises two separate sub-systems:

one for +270 VDC and one for −

270 VDC.

16. A device according to claim 12, wherein the storage device comprises two sub-assemblies and two static DC/DC converters.

17. A device according to claim 12, wherein the storage device comprises an active filtering function.

18. A device according to claim 12, in which the aircraft is an airplane.

21. An aircraft comprising a device according to claim 12.

22. An aircraft comprising a device configured to implement the method according to claim 14.

19. A method to generate electricity on board an aircraft including plural generators and plural air-conditioning units having an outside air intake, the method comprising:

under normal functioning supplying the air-conditioning units with high voltage, and under emergency functioning using the air-conditioning units as emergency generators; and

ensuring supply of electricity, during transitory periods between normal functioning and emergency functioning and on landing of the aircraft, by a storage device.

20. A method according to claim 19, wherein under normal functioning the air-conditioning units are supplied via static converters used as inverters, and wherein under emergency functioning the air-conditioning units are used to supply an essential bus bar on which critical loads of the aircraft and the storage device are connected, via the static converters used as rectifiers.
