FIBERCELL OVERHEAT HAZARD DETECTION SYSTEM.
Abstract
The purpose of the program was the development of an airborne overheat hazard detection system, utilizing the proprietary power-generating Fibercell concept as the sensor. Such a sensor must have a detection capability in the primary temperature range from 300F to 1000F, plus the capacity to withstand transient temperatures in excess of these limits. In general, Fibercell consists of a ceramic electrolyte electrochemical cell in the shape of a fiber, which is dependent on its temperature for electrical power output. Since the electrolyte resistivity is logarithmically related to temperature, the cell power output lessens rapidly with decreasing temperature. Below a particular temperature (determined by ceramic electrolyte composition), the cell is effectively disconnected from the alarm system -- a behavior that lends itself to long service life of the cell. During this program, developmental work was directed toward: an improvement of Fibercell performance at the lower end of its operating range; the design of sensors for airborne alarm systems; and the evaluation of sensors under simulated alarm and aircraft conditions to determine their mechanical stamina, as well as their performance as overheat condition sensors.
