An on-board inert gas generation system is disclosed that includes an air separation module that is configured to produce nitrogen enriched air from a non-enriched air. The non-enriched air to the air separation module has a desired operating temperature range. A compressor system is in fluid communication with the air separation module. The compressor system is configured to rotate at a speed and provide the non-enriched air to the air separation module. A controller is in communication with the compressor system and is configured to reduce the speed in response to a parameter reaching an undesired value, which would result in a non-enriched air temperature that would exceed the desired operating temperature range. The reduced speed is selected to maintain the non-enriched air temperature within the desired operating temperature range.

A method for correcting a hot start condition in a gas turbine without requiring a complete shutdown and reinitiation of the startup sequence includes temporarily interrupting the flow of fuel to the engine for a brief period of time following detection of an impending hot start condition.
