RADIATION

THE PROPOSED PROJECT WOULD EVALUATE THE FEASIBILITY OF DEVELOPING A WATER FOG OR SPRAY GENERATOR TO CONTROL ON BOARD AIRCRAFT FIRES BY ATTENUATING RADIATIVE HEAT TRANSFER . INFRARED (IR) RADIATION FROM THE FLAME MAINTAINS COMBUSITION OF THE BURNING SURFACE AND AIDS IN THEINGITION OF COLD SURFACES--THEREBY SPREADING THE FIRE. OPTIMAL USE WILL NEED TO BE MADE OF THE WATER, SINCE IT WILLBE CARRIED ON THE AIRCRAFT AND THUS REPRESENTS LOSS OF FUEL CAACITY OR PAYLOAD. THE OBJECTIVE OF THE PROPOSED PHASE I STUDY IS TO DETERMINE THE FEASIBILITY OF THE WATER FOG GENERATOR FOR ATTENUATING FIRE RADIATION FROM CABIN FIRES. THE FEASIBILITY OF THE METHOD WILL BE DETERMINED BY A COMBINATION OF TASKS WHICH INCLUDE THE SELECTION OF OPTIMUN DROPLET SIZE THROUGH ANALYSIS, THE DESIGN AND LABORATORY TESTING OF A SPRAY RSULTING ON-BOARD SYSTEM. BASED ON THER E RESULTS OF PHASE I, A PHASE II PROGRAM WILL BE PURSUED WITH THE GOAL OF DEVELOPING APROTOTYPE FOG GENERATOR FOR RADIATION ATTENUATION.
