FIELD: aircraft engineering.
SUBSTANCE: invention relates to aircraft power recovery. Method of energy recovery in aircraft consists in fact, that when aircraft is on the ground, heat energy, dissipated by auxiliary power generation (20), is recuperated with heat exchanger (1) at level of its releasing (14) to provide regenerative cycle of turbocompressor (10) for creation of additional mechanical energy to auxiliary power generation (20). When aircraft is at height, turbocompressor (10), driven by air recuperated at cabin exit (40), then heated by heat exchange (1) at level of releasing (14), produces addition to compression of load compressor (22) to provide compression ratio, required to supply air to conditioning system (30).
EFFECT: invention provides optimum energy recovery of aircraft both at height and ground.
