Claim 0:
1. A system for converting and transporting electrical energy in an aircraft propelled by at least one turbojet engine on which power can be bled or injected via a high-pressure and/or low-pressure turbine shaft and including at least one gas turbine to provide power transients, wherein each of said high-pressure and/or low-pressure turbine shafts is connected to a first doubly-fed asynchronous machine delivering, on the one hand, a first three-phase AC voltage over an AC distribution grid and on the other hand a second polyphase AC voltage for a first AC/DC bidirectional converter supplying a DC voltage over a DC distribution grid, at least one second DC/AC bidirectional converter connected to said DC distribution grid converting this DC voltage into a third polyphase AC voltage supplying at least one second doubly-fed asynchronous machine engaged with a rotation shaft of said at least one gas turbine, said second doubly-fed asynchronous machine further delivering a fourth polyphase AC voltage over said AC distribution grid.
