Fire tests were conducted in a turbojet powerplant installation to determine the effectiveness of an Ediaon and a Honeywell Ultraviolet Fire Dectection System. The four sensor units for each system were installed on the forward bulkhead of the engine nacelle's accessory nd compressor compartment (Zone II) and provided surveillance aft to the firewall. Fires having fuel-flow rates of 0.04 and 0.13 gallons per minute were initiated about 12 inches forward of the firewall at several locations around the periphery of the engine.

As part of the coordinated AMC fire-safe fuel research program, the U.S. Army Fuels and Lubricant Research Laboratory (AFLRL) was instructed to undertake the following: (1) Conduct an engine parameter optimization study with the "fire-safe fuel".

Development in the UK of aircraft fuels which resist fire in a crash has concentrated almost entirely on polymeric additives which prevent kerosene fires under realistic crash conditions with both flame and heated duct ignition sources. High internal phase ration emulsions gave no fire resistance in these tests.

The purpose of this effort was to determine the effectiveness of several newly developed identification beacons for airport emergency vehicles. Fourteen different light bar configurations were tested on the National Aviation Facilities Experimental Center (NAFEC) airport during various environmental conditions and human appraisal of the different combinations was performed for suitable airport use. The results lead to conclusions as to which signal characteristics are most effective for use within the aircraft movement areas of airports.

A series of vertical gunfire tests was conducted at Wright-Patterson AFB in order to assess the effectiveness of fuel additives in reduction of the fire and explosion hazards that can be associated with kerosene (JP8) fuel under gunfire conditions. This program considered commercial additives which have been developed for the fire safe fuel efforts of the FAA. the Army, and the British Government. The additives were intended to prevent fuel mist or spray during a crash situation. -This effort considered the effectiveness of these additives at a concentration of approximately 0.3% wt. in the prevention of explosions of fuel mist or spray as a 50 caliber armor piercing incendiary (API) ordnance round passes through the liquid-vapor interface. Results indicated that additives could be 'effective. Two of the four materials evaluated, CONOCO AM-l and Imperial Chemical Industries. Ltd. FH-4 reduced average pulse pressure' rise to less than 10 psi as compared to 40 psi rise with neat JP-8. Additives were not effective when evaluated in JP-4 fuel. , .
