Abstract:
The ullage in aircraft fuel tanks becomes potentially explosive when the oxygen concentration of the fuel vapor-air mixture exceeds approximately 9 by volume. To insure effective and efficient use of active fuel tank inerting under a wide range of environmental and operational conditions, the oxygen concentration must be continuously monitored. This study has resulted in the development of a laboratory breadboard model of a sensor which is specific for oxygen. The concept employs a change in frequency of a radio-frequency RF oscillator due to the paramagnetic property of oxygen. Demonstration of feasibility was limited to ambient laboratory conditions.
