Abstract

An air separation module has an inlet for receiving a source of air. The inlet communicates with an inlet manifold and the inlet manifold communicates with a plurality of canisters. The canisters are provided with hollow fibers constructed such that oxygen can permeate the fiber and nitrogen passes through the fiber. A jacket manifold surrounds the canisters and the jacket manifold receives oxygen that has permeated the fibers. The canisters extend to a downstream end, and to an outlet. The jacket manifold communicates with a jacket outlet manifold and an outlet for separated oxygen. The outlet for the jacket manifold is at a downstream end of the canisters.

First claim

The invention claimed is:

1. An onboard nitrogen generating system comprising:
a source of hot air;
an air separation module having an inlet for receiving a source of air, said inlet communicating with an inlet manifold, and said inlet manifold communicating with a plurality of canisters, said canisters being provided with hollow fibers constructed such that oxygen can permeate the fiber and nitrogen passes through the fiber;
a jacket manifold surrounding said canisters, and s…
