An on-board inert gas generating system includes a flow control valve modulated according to changes in ambient conditions to minimize changes to oxygen content within a fuel tank. The quality of the nitrogen-enriched air stream that is provided by the air separation module varies in response to flow. Higher flow rates through the air separation module removes less oxygen relative to lower flow rates. The amount of flow through the air separation module that produces the least amount of oxygen within the fuel tank is determined for an ambient pressure an...
What is claimed is: 1. A method of controlling oxygen content within and aircraft fuel tank ullage, said method comprising the steps of: (a) determining a rate of change in oxygen content within the fuel tank ullage based on atmospheric pressure and temperature of an environment outside of the aircraft and external of the fuel tank ullage, wherein the atmospheric pressure and temperature of the environment outside of the aircraft and the fuel tank ullage are measured by sensors disposed outside of the fuel tank ullage; (b) determining a desired flow rat...
