Abstract:

The report describes the development, design, fabrication and testing of a self-generating overheat detection system for USAF aircraft. The system consists of a loop sensor cable connected by way of a junction box and thermocouple type extension wires to a control unit. The developed sensor consists of a continuous coaxial cable which changes its electrical properties as cable temperature is changed. Here, cable thermoelectric voltage as well as impedance is utilized in establishing alarm signal levels. Theoretical work involving such factors as thermocouple signal transmission and detection, together with an investigation of cable materials and electronic componentry available for aircraft use is described.
