U. S. Army Aircraft In-Flight Fire Detection and Automatic Suppression Systems
Abstract
In-flight fire reports at U.S. Army Materiel System Analysis Agency (combat) and U.S. Army Agency for Aviation Safety (noncombat) for UH-1, AH-1 and CH-47 helicopters were studied to determine the cause and location of helicopter compartment fires. Two Army helicopter operating bases were visited for firsthand information. The in-flight fires were divided into groups, and from the number of incidents in each group, a priority was established to secure the most effective results toward development of automatic suppression systems. A survey was made of fire detectors and methods of extinguishment and suppression, and the characteristics of such systems were evaluated for possible use in the fire suppression systems. System concepts were developed and methods of detection and extinguishment/suppression were selected as most suited for integration into the aircraft system. Design criteria for the various concepts were developed and recommendations made as to systems to be used in the test phase. Simulations of engine, oil cooler, and electronics compartments were fabricated, and selected systems were tested.
