Aircraft ventilation device

摘要

The ventilation device according to the invention includes a fan and an inverter. The fan comprises a rotary electrical machine and a wheel for setting an air flow into motion, integral with the rotary machine to set it in rotation. The inverter is connected to the rotary machine and, in one motor power mode of the ventilation device, is suitable for forming the supply current of the rotary machine. The inverter is suitable for being connected to a power supply network. The inverter is reversible and is, in a generating mode of the ventilation device, suitable for converting the electrical energy supplied by the rotary machine when it is driven mechanically by the wheel and injecting said converted electrical energy into the power supply network.

1. An aircraft ventilation device comprising:
a fan comprising a rotary electrical machine and a wheel for setting an air flow in motion, integral with the rotary machine for setting in rotation thereof; and an inverter suitable for being connected to a power supply network, and to which the rotary machine is connected, the inverter being, in one motor supply mode of the ventilation device, suitable for forming the supply current of the rotary machine, the inverter being reversible and being, in an energy generating mode of the ventilation device, suitable for converting the electrical energy supplied by the rotary machine when it is mechanically driven by the wheel, and injecting said converted electrical energy into the power supply network, wherein the ventilation device comprises a controller and a distributor extending transversely in front of the wheel, the distributor including vanes extending radially, the controller, controlling the orientation of the vanes so that in the motor supply mode, the vanes are oriented in a first position maximizing an air flow generated by the wheel when it is driven by the rotary machine, and, in the energy generating mode, the vanes are oriented in a second position maximizing the electrical energy supplied by the rotary machine when it is driven by the wheel, itself being driven by a flow of air passing through the distributor, the first and second positions being distinct from one another, wherein the inverter comprises a set of switches, and wherein, in the energy-generating mode, the set of switches of the inverter forms a bridge rectifier controlled by the controller.
