An aircraft air conditioning system, powered solely using electrical energy, to draw bleed air from outside the aircraft and deliver conditioned air to the aircraft's interior, includes at most three motorized rotary machines, which include: independent first and second motorized turbocompressors, each turbocompressor includes a turbine compressor and an electric motor; and a motor compressor interconnected between the turbocompressors via an interconnection pipe. The motor compressor: generates a primary air flow, which drives a secondary air flow, allowing a breathing air flow to be cooled in a first operation phase, corresponding to a ground operation or at relatively low altitude and relatively low aircraft speed; be at shutdown or at low idle in a second phase of operation at relatively low altitude and relatively high aircraft speed; and, provide a top up breathing air flow in a third phase of operation at relatively high altitude and relatively high aircraft speed.

Air conditioning system for a 'more electric' airplane

Energy management on board an aircraft includes: a plurality of thermal and electrical energy sources, a plurality of loads which are capable of being supplied with power by the various energy sources, among which at least one load is capable of being supplied with power by an electrical energy source and by a thermal energy source, and real-time management means for energy transfers from the various energy sources to the various loads as a function of the present and future energy requirement of the various loads and the present and future availability of the various sources, with the management means providing a permanent and standardized correlation between thermal and electrical energies.
