Hybrid fuel tank inerting system
First Claim
1. An inerting system for an aircraft fuel tank comprising:
- a compressor with an inlet connected to the aircraft fuel tank and an outlet connected to a coalescer;
a driving turbine connected to drive the compressor; and
an oxidation reactor,a vapor outlet of the coalescer being connected to an inlet of the reactor,an outlet of the reactor being connected to the inlet of the turbine, andan outlet of the driving turbine being connected to the aircraft fuel tank.

Abstract
A self-regulating system for reducing concentration of hydrocarbon vapor in a container may be performed by introducing air into the container and extracting a mixture of air and vapor from the container. The extracted mixture may be compressed with a compressor to produce a flow of compressed mixture of air and vapor. The compressed mixture may be passed through an oxidation reactor that may be either catalytic or thermal to produce a flow air and CO2. A turbine may be driven with the flow of air and CO2. The compressor may be driven with the turbine. Extraction from the container may continue until vapor concentration is low enough so that flow of CO2 and air from the reactor is insufficient to drive the turbine.
