DEVELOPMENT OF A HAZARDOUS VAPOR DETECTION FOR ADVANCED AIRCRAFT
Abstract
A program was conducted to evaluate, develop, and construct instrumentation for the detection of hazardous vapors aboard advanced aircraft. Prototype detection systems were constructed both for monitoring JP-6 fuel vapor in aircraft compartments and for monitoring oxygen in the ullage space of fuel tanks. These systems will be further evaluated in flight tests. Detection of both species is accomplished by the use of a catalyst-coated thermistor sensor. Catalytic oxidation occurring at the catalyst surface liberates heat, which is sensed by the thermistor. The JP-6 sensor consists of a simple probe which can be mounted directly in the space to be monitored. No sampling system is required. The oxygen sensor is more complicated, necessitating flow connections to an external pump and gas supplies. Methods for achieving desired goals in specific installations and operating modes are indicated and are relatively simple. (Author)
