Abstract

Leaks on the Space Shuttle while on the Launch Pad have generated interest in hydrogen leak monitoring technology. Microfabricated hydrogen sensors are being fabricated at Case Western Reserve University and tested at NASA Lewis Research Center. These sensors have been integrated into hardware and software designed by Aerojet and Marhsall Space Flight Center. This complete system allows for rapid, multipoint leak monitoring. The monitoring system processes data from the hydrogen sensors and presents the operator with a visual indication of the leak location and magnitude. Although the leak monitoring system was designed for hydrogen propulsion systems, the possible applications of this monitoring system are wide ranged. This system is in operation in an automotive application which requires high sensitivity to hydrogen.
