AI Technical Summary
Technical Problem
Conventional aircraft fuel tank inerting systems face issues with ASMs having short service life due to contamination and high temperature, requiring costly filtration and cooling, and vortex tubes offer fixed separation performance or are prone to clogging, necessitating backup systems.
Method used
A vortex tube assembly with a movable throttle pin in the inlet passage allows adjustable separation performance and acts as a failsafe, reducing reliance on filtration and backup systems by clearing obstructions and adapting to varying flow requirements.
Benefits of technology
The vortex tube assembly provides reliable nitrogen-enriched air supply with reduced need for filtration and backup equipment, maintaining performance despite fluctuations and potential faults.
