Advanced Air Separation Module Performance Evaluation
Abstract
Results of an experimental performance evaluation of two advanced lightweight permeable membrane(PM) air apace modules(ASM) are presented. ASMs produce nitrogen enriched air which is used for airplane fuel tank inerting. The airplane inerting system is termed On-Board Inert Gas Generator System (OBIGGS). ASMs were obtained from two sources: A/G Technology Corp. and Permea Inc Steady state performance envelope, long term endurance, hot/cold start-up on/off cycling, moisture, vibration, contaminant, and high temperature destructive tests were conducted. Results indicate that a significant breakthrough in OBIGGS weight reduction has been achieved. Both the A/G and Permea ASMs offer significant reductions in weight over present SOTA (state-of-the-art) ASM technology. Performance of the A/G and Permea ASMs is directly compared to other ASM technology in terms of ASM weight as well as total airplane penalties which include bleed air usage and bleed system component weight. Comparisons indicate that the advanced ASMs will allow significant weight reductions in the bleed air system compared to present SOTA ASM technology. This was accomplished by using less bleed air at higher temperatures. Basic ASM performance models are presented along with analysis of ASM moisture sensitivity, pressure drop, and thermal response.
