Abstract
An aircraft turboprop engine (310) including at least a low-pressure body (12) and a high-pressure body (14), possibly also an intermediate-pressure body. At least one of the bodies includes a compressor. The low-pressure body drives a first gearbox (16) The turboprop engine also includes at least one load compressor (60) for supplying air to an air-conditioning circuit of an aircraft cabin. A rotor (61) of the load compressor is coupled to the low-pressure body. The load compressor (60) includes an air inlet (62) connected to a conduit (72) to bleed air from the compressor of the turboprop engine when all of the aforementioned bodies include only a single compressor, or from the compressor of the low-pressure body or the compressor of the intermediate-pressure body of the turboprop engine when all of the bodies include at least two compressors.
