Abstract : The report summarizes the results of an in-house effort to develop and demonstrate the feasibility of an integrated fire and overheat detection system for an aircraft engine nacelle. The integrated system was conceived in 1965 as a means of decreasing the number of nondetected engine nacelle fires and the incidence of false fire warnings on operational Air Force aircraft. Analysis of the reported engine nacelle fires and fire warnings shows that approximately 50% of the fires were not detected by the fire or overheat detection system during the six-year period 1965-1970, and 83% of the fire and overheat warnings were false. Two integrated systems were developed to demonstrate total system feasibility, and these systems were further evaluated on flight test aircraft. The report presents the results of this evaluation.
