Abstract
A system and a method for ventilating a plant including an auxiliary power unit (APU) in an aircraft compartment are disclosed. The compartment is ventilated in an independent manner with individualized air feeds to each item of equipment concerned. According to one embodiment, a system for feeding and ventilating an aircraft auxiliary power source plant includes an APU and items of equipment mounted in connection with the APU. The APU is fitted with an exhaust nozzle which leads into a gas discharger mounted outside the compartment. Separate and independent ducts channel air between air inlets made through the compartment, and the APU and items of equipment. At least one ventilation duct that is separate and independent from the other ducts is coupled to an air inlet of the compartment in order to ventilate the APU and the items of equipment of the plant.
