A Standard Aircraft Diffusion Flame: Spectral Characteristics and a Feasibility Study for Developing an Alternate Calibration Source for Aircraft Optical Fire Detection Systems.
Abstract
The standard aircraft diffusion flame source presents practical difficulties due to its lack of controllability and its production of large amounts of smoke and soot. A source which is more convenient to handle, but which emulates the spectral and power characteristics of the standard flame, might prove useful. The requirements of such a flame were evaluated by measuring the spectral and power characteristics of a standard aircraft diffusion flame over the spectral range 2.5 micrometers to 20 micrometers. The total power output in this range was on the order of 1000 watts. About one-fourth of this was from the 4.4 micrometers carbon dioxide emission and; a small amount was due to weaker emissions of water vapor and carbon dioxide; and the remainder was due to thermal emission from soot particles. Originator furnished keywords include: diffusion flame, optical fire detection.
