FUEL TANK INERTING APPARATUS FOR AIRCRAFT

摘要

A system includes a first flow path fluidly connecting a first supply to an inerting apparatus. A second flow path connects a second supply to a turbine of a compressor device. A first valve, located within the first flow path, is configured to be open in a first state and closed in a second state. The first valve is configured to allow a supply of air from the first supply to an inerting apparatus directly. A second valve, located within the second flow path, is configured to be closed in the first state and open in the second state. The second valve is configured to allow a supply of air from the second supply to drive the turbine of the compressor device. When in the second state, the compressor device is operated to compress air from the first supply prior to the air being supplied to the inerting apparatus.

1. A system for supplying conditioned air to an inerting apparatus of an aircraft, the system comprising:
a first air supply source; a first flow path fluidly connecting the first air supply source to an inerting apparatus; a compressor device driven by a turbine; a second air supply source; a second flow path fluidly connecting the second air supply source to the turbine of the compressor device; a first valve located within the first flow path and configured to be open in a first state and closed in a second state, the first valve configured to allow a supply of air to flow from the first air supply source to the inerting apparatus directly; and a second valve located within the second flow path and configured to be closed in the first state and open in the second state, the second valve configured to allow a supply of air to flow from the second air supply source to drive the turbine of the compressor device, wherein, when in the second state, the compressor device is operated to compress air from the first air supply source prior to the air being supplied to the inerting apparatus.
