Abstract
Within the U. S., the pollutant emissions at Navy and Air Force airbases are not regulated by civil law. However, there is a desire to be a good neighbor to the local population. On the other hand, military engine test facilities are designated as ground emission sources which are subject to civil air quality regulations. Both situations contribute to a Navy and Air Force requirement for the generation of air quality scenarios, which in turn requires ready access to engine emissions data. A considerable body of emissions data has been collected for U. S. military aircraft engines over the last twenty years. However, this data is not readily accessible, because it is distributed in a variety of technical publications, and is not presented in a consistent format. Therefore the Navy, with Air Force cooperation, has sponsored a program to develop an engine emissions database system tailored to their requirements, for use on a microcomputer. The program was conducted by Northern Research and Engineering Corporation. The resulting database contains all of the available emissions data, as well as background information on each engine model and the conditions for each test. All of the unclassified operational engine models of the Navy and Air Force are listed, whether or not emissions data are available. When emissions data is not available for a particular model, but there is a similar engine model whose data can reasonably be substituted, this is identified. The system provides an easy and versatile means of accessing the available emissions data. In general, the computerized database approach can increase the value of many types of experimental data.
