Abstract:
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 said jacket manifold for receiving oxygen that has permeated the fibers; said canisters extending to a downstream end and into a nitrogen outlet; said jacket manifold communicating with a jacket manifold outlet and an outlet for separated oxygen, said jacket manifold outlet being at a downstream end of said canisters; said oxygen outlet is also at said downstream end of said air separation module; and said oxygen outlet being connected to a use for oxygen and said nitrogen outlet being connected to a use for nitrogen.
