Research Institution
Makel Engineering, Inc. proposes to develop a MEMS Exhaust Monitoring System consisting of several different types of MEMS based sensors using silicon carbide, silicon, and other novel thin film structures to provide measurement of key species. The use ofMEMS sensor technology suitable for high temperature environments enables in-situ analysis of emissions. The sensors can be placed at multiple locations, enabling spatial distribution of the chemical species. MEMS sensors also enable real-timemonitoring, providing accurate mapping of composition variation as a function of time.Our proposed system is being developed to support ground engine tests performed by AEDC. Currently, the composition of the exhaust stream is monitored using conventional analytical equipment. The equipment is expensive in terms of procurement,installation, and maintenance. The gas samples are drawn into the system through long heated sampling lines using pumps which increases the analysis time.The proposed MEMS Exhaust Monitoring System greatly simplifies current AEDC engine test activities, as it can be directly integrated with specialty sample probes, providing much faster response time and eliminating the need of long, heated lines andpumping systems. The proposed device offers a lower cost solution, which can be replicated, enabling tests in multiple locations.
